The diminishing nutritional quality of rice with increasing concentrations of atmospheric CO2 is currently a major global concern. The present study was designed with the objective of assessing the impact of biofertilisers on grain quality and iron homeostasis in rice under elevated CO2. A completely randomised design with four treatments ([KAU, POP (control), POP+Azolla, POP+PGPR, and POP+AMF]), each replicated three times under ambient and elevated CO2 conditions, was followed. The analysed data revealed that yield, grain quality, and iron uptake and translocation were modified in an unfavourable manner under elevated CO2, which was reflected in the lower quality and iron content of the grains. The response of iron homeostasis in the experimental plants to the application of biofertilisers, especially plant-growth-promoting rhizobacteria (PGPR), under elevated CO2 strongly suggests the possibility of utilising them for designing iron management strategies for achieving higher quality in rice.

Eco-friendly anti-algal agents are in demand for preventing the growth of unwanted algae. Green synthesized nanoparticles exhibit antimicrobial properties and have been used as a better alternative against chemical and physical processes. In the present study, treatment of silver nitrate with leaf extracts (5% w/v) of Tinospora cordifolia, a plant with proven antimicrobial effects, exhibited UV-visible absorption maxima between 440-460 nm after 1h indicating bioreduction of silver to nanoparticles. The green synthesised silver nanoparticles (5 mgl-1) exhibited inhibition zones against Chlamydomonas reinhardtii in in vitro agar assays. Treatment with green synthesised silver nanoparticles during exponential phase of algal growth resulted in significant reduction in algal population, carbohydrate, protein and chlorophyll contents confirming the anti-algal potential. This is the first report on the growth inhibitory potential of green synthesised silver nanoparticles against green algae.

The damage caused by high temperature is one of the most important abiotic stress affecting rice production. Reproductive stage of rice is highly susceptible to high temperature. The present investigation was undertaken to identify polymorphic microsatellite markers (SSR) associated with heat tolerance. The rice cultivars NERICA– L 44 (heat tolerant) and Uma (heat susceptible) were crossed to generate F1 and F2 populations. The F2 population was subjected to heat stress at >38°C and the 144 F2 plants were evaluated for their tolerance. The results note that the mean of the F2 population was influenced by the tolerant parent with regards to the traits of plant height, membrane stability index, photosynthetic rate, stomatal conductance, evapotranspiration rate, pollen viability, spikelet fertility and 1000 grain weight. Ten each of the extremely susceptible and tolerant plants were selected based on the spikelet fertility percentage. Their DNA was pooled into tolerant and susceptible bulks and Bulked Segregant Analysis (BSA) was carried out using 100 SSR markers to check for polymorphism. The survey revealed a polymorphism of 18% between the parents. RM337, RM10793, RM242, RM5749, RM6100, RM490, RM470, RM473, RM222 and RM556 are some of the prominent markers that were found to be polymorphic between the parents and the bulks. We performed gene annotation and enrichment analysis of identified polymorphic markers. Result revealed that the sequence specific site of that chromosome mostly enriched with biological processes like metabolic pathway, molecular mechanism, and subcellular function. Among that RM337 was newly reported marker for heat tolerance. Expression analysis of two genes corresponds to RM337 revealed that LOP1 (LOC_Os08g01330) was linked to high temperature tolerance in rice. The results demonstrate that BSA using SSR markers is useful in identifying genomic regions that contribute to thermotolerance.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
The essential package of palliative care for cervical cancer (EPPCCC), described elsewhere, is designed to be safe and effective for preventing and relieving most suffering associated with cervical cancer and universally accessible. However, it appears that women with cervical cancer, more frequently than patients with other cancers, experience various types of suffering that are refractory to basic palliative care such as what can be provided with the EPPCCC. In particular, relief of refractory pain, vomiting because of bowel obstruction, bleeding, and psychosocial suffering may require additional expertise, medicines, or equipment. Therefore, we convened a group of experienced experts in all aspects of care for women with cervical cancer, and from countries of all income levels, to create an augmented package of palliative care for cervical cancer with which even suffering refractory to the EPPCCC often can be relieved. The package consists of medicines, radiotherapy, surgical procedures, and psycho-oncologic therapies that require advanced or specialized training. Each item in this package should be made accessible whenever the necessary resources and expertise are available.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Women with cervical cancer, especially those with advanced disease, appear to experience suffering that is more prevalent, complex, and severe than that caused by other cancers and serious illnesses, and approximately 85% live in low- and middle-income countries where palliative care is rarely accessible. To respond to the highly prevalent and extreme suffering in this vulnerable population, we convened a group of experienced experts in all aspects of care for women with cervical cancer, and from countries of all income levels, to create an essential package of palliative care for cervical cancer (EPPCCC). The EPPCCC consists of a set of interventions, medicines, simple equipment, social supports, and human resources, and is designed to be safe and effective for preventing and relieving all types of suffering associated with cervical cancer. It includes only inexpensive and readily available medicines and equipment, and its use requires only basic training. Thus, the EPPCCC can and should be made accessible everywhere, including for the rural poor. We provide guidance for integrating the EPPCCC into gynecologic and oncologic care at all levels of health care systems, and into primary care, in countries of all income levels.

PURPOSETo enable design of optimum palliative care for women with cervical cancer, we studied the most common types of suffering and their severity, prevalence, and duration.METHODSWe first reviewed the literature on the major types, severity, prevalence, and duration of suffering associated with cervical cancer. We then conducted a modified Delphi process with experts in cervical cancer care to supplement the literature. For each type of suffering, we distinguished between decedents (those who die from cervical cancer in a given year) and nondecedents (those who have cervical cancer in a given year but do not die). By applying the suffering prevalence and duration estimates to the number of decedents, nondecedents, and family caregivers in 2017, we were able to estimate their palliative care needs and the intensity of palliative care needed to respond adequately to this suffering.RESULTSThere is a high prevalence among decedents of moderate or severe pain (84%), vaginal discharge (66%), vaginal bleeding (61%), and loss of faith (31%). Among both decedents and nondecedents, there is a high prevalence of clinically significant anxiety (63% and 50%, respectively), depressed mood (52% and 38%, respectively), and sexual dysfunction (87% and 83%, respectively). Moderate or severe financial distress is prevalent among decedents, nondecedents, and family caregivers (84%, 74%, and 66%, respectively). More than 40% of decedents and nondecedents are abandoned by their intimate partners. Most patients experience some combination of moderate or severe physical, psychological, social, and spiritual suffering. In total, 258,649 decedents and 2,558,857 nondecedents needed palliative care in 2017, approximately 85% of whom were in low- and middle-income countries where palliative care is rarely accessible.CONCLUSIONAmong women with advanced cervical cancer, suffering is highly prevalent and often severe and multifaceted.

Introduction: As the pandemic of COVID-19 stretches, its wings across the different parts of the world over the past few months, it is very likely that mental health problems increase, particularly among the health-care workers who have higher risk of exposure to the disease and also to sufferings of the people affected with the disease. Objective: To assess the prevalence and factors associated with depression, anxiety, and stress among health-care workers from Kerala during the COVID-19 pandemic. Materials and Methods: A cross-sectional study among 544 health-care workers from Kerala was conducted by a self-administered online questionnaire in Google Forms by chain referral sampling with Depression, Anxiety, and Stress Scale-21 scale during initial phase of the COVID-19 pandemic. The tests of significance used were Mann–Whitney U-tests and Kruskal–Wallis tests. Odds ratios and 95% confidence interval are estimated. Results: During the early pandemic period, 9.7% of health-care workers had mild depression and 13.3% had moderate-to-severe depression. While 4% had mild anxiety and 3.5% had moderate-to-severe anxiety, about 6.8% had mild stress and 6.4% had moderate-to-severe stress. The anxiety symptoms were significantly higher among nurses compared to doctors. Emotional and social support from higher health authorities is a significant protective factor against stress and depression. Frontline workers have 84% higher risk to have depression. Conclusions: Frontline health-care workers who are directly involved in the screening, diagnosis, treatment, and care for patients with COVID-19 are at higher risk of experiencing poor mental health outcomes. Emotional and social support from higher health authorities is a significant protective factor against depression and stress among health-care workers.

High temperature induced by climatic fluctuations are an important threat for plant growth, development and quality of agricultural produces. Adaptableness to environmental changes generally derives from a large set of genetic traits affecting physio-morphological, biochemical and agronomic parameters. Therefore, the identification of genotypes with higher yield and good quality parameters at high temperatures is becoming increasingly necessary for future breeding programs. Here, we analyzed the performance of different tomato genotypes grown under elevated temperatures in terms of yield and nutritional quality of the fruit. High temperature stress was induced from flower initiation to maturity stage by keeping the pots in a temperature controlled green house facility for 45 days. The quality and yield parameters were taken at the harvesting stage. Starch and soluble sugar concentration in the leaves of tomato genotypes showed significant reduction in its amount under heat stress. Titrable acidity (TA), total soluble solids (TSS) and ascorbic acid content of tomato fruits were highest under high temperature conditions compared to ambient condition but lycopene content decreased with rise in temperature. The yield attributes viz., number of fruits/plant, fruit set %, average fruit weight (g), yield per plant (g/plant) were significantly lower for Arka Saurabh, Arka Rakshak and Pusa Rohini when compared to other genotypes under study. Molecular characterization of selected 22 tomato genotypes were assessed using 25 simple sequence repeat (SSR) markers. Phylogenetic tree was constructed by the unweighted neighbour-joining method (UPGMA) using NTSYSpc cluster analysis software. The Jaccard's similarity matrix was constructed using the SIMQUAL method using UPGMA algorithm in NTSYSpc. Jaccard's similarity matrix among these tomato genotypes ranged from a minimum of 0.22 to a maximum of 1 with an average genetic similarity of 0.67. Hence this study has importance in identifying genotypes that could maintain good quality and higher yield under high temperature condition.

Field experiments were conducted at two different geographical regions viz., tropical region (Naraseepuram village, Coimbatore) and temperate region (Kookal village, Kotagiri, The Nilgiris) in summer and winter season’s to assess the bioefficacy of insecticides used against Diamondbackmoth (DBM), Plutella xylostella and their potential impact on natural enemies in cauliflower. The results revealed that the diamide insecticides like cyantraniliprole 10.26 OD @ 60 g a.i ha-1, chlorantraniliprole 18.50 SC @ 10 g a.i ha-1 and flubendiamide 20 WG @ 18.24 g a.i ha-1 registered more than 95 percent population reduction over untreated control followed by emamectin benzoate 5 SG @ 10 g a.i ha-1 and thiodicarb 75 WP @ 750 g a.i ha-1. Quinalphos 25 EC @ 500 g a.i ha-1and chlorpyriphos 20 EC @ 400 g a.i ha-1 were observed as least effective among the treated insecticides. The diamide insecticides recorded considerably less toxic effect on the natural enemies, especially spiders and coccinellids. Population reduction of natural enemies was noticed immediately after insecticide spray but it gradually increased and was recorded on par with the control population. Hence, cyantraniliprole 10.26 OD @ 60 g a.i ha-1, chlorantraniliprole 18.50 SC @ 10 g a.i ha-1 and flubendiamide 20 WG @ 18.24 g a.i ha-1 can be used as potential component in the integrated pest management against DBM in cole crops.

Pharmacology - Abstract
Snake bite is a life-threatening neglected tropical infection reporting high mortality across the world including India. Out of the available yearly statistics of this occupational hazard caused 4.5-5.4 million people and nearly 1,38,000 fatalities were reported globally. Several factors such as the low availability of antivenom, inadequate health centres in rural areas, poor transportation facilities affected the higher number of morbidity and mortality cases of snake bite. The prognostic and diagnostic approach towards the snake bite infection is difficult due to its complexity in venom. The conventional therapy is polyvalent antivenom derived from horses or sheep, with its limitations. The traditional physicians use plants and other herbs as its sustainable remedy for snake bite treatment. Nearly, 523 plant species from 122 families reported their neutralizing property against toxic venom. The secondary metabolites extracted from plants, are capable of reducing the toxic effects of the venom. Many research works has been reported the inhibitory potential of the plant compounds against the snake venom enzymes. Therefore, there is a necessity for increasing therapeutic studies on plant metabolites and the development of an antidote for the better treatment of snakebite. This review article discusses various herbal plant used for snake bite in India.

General Medicine - Abstract
An experiment was conducted at the Department of Seed Science and Technology, College of Agriculture, Vellayani to study the influence of gamma irradiation in enhancing storage life of grain cowpea. The experiment consists of six treatments (100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy and control) with different doses of gamma rays. All the treatments were effective in control of pulse beetle infestation without any seed damage and consequently no weight loss compared to control with 56.333, 28.182 per cent seed damage and weight loss. The treatments showed higher germination parameters compared to control at lower doses of gamma rays. The treatment T2 (200 Gy) recorded highest seed germination percentage (84.33%). Speed of germination, seedling shoot length and seedling dry weight was highest at T2 (200Gy) with 32.13, 11.83 cm and 0.703 g. Seedling root length was highest at T1 (100 Gy) with 13.84 cm. Seedling vigour index I and II were maximum at T2 (200 Gy) with 2130.49 and 59.28. In the field experiment, progressive decrease in all morphological parameters was observed with increase in doses of beyond 200 Gy. No significant variation was observed in 100 Gy, 200 Gy and control. However, among all the gamma doses, 200 Gy (T2) recorded the least seed damage, weight loss and improvement in germination compared to control.

Limited information exists regarding the ideal packaging and storage conditions for optimum quality and storage life of rambutan. In this study, the physicochemical properties of rambutan fruits were monitored during storage. Fruit were packaged in Ventilated LDPE (150 gauge), Ventilated Polypropylene (PP) (100 gauge), Polystyrene tray with cling film wrap, Shrink wrapping and stored under room (30±2?C and RH 80-85%) or refrigerated (10±2?C and RH 90-95%) conditions were investigated for their potential to enhance the quality and extend the storage life of the fruit. Rambutan pre-packaged in ventilated polypropylene (PP) reduced weight loss. Refrigerated storage extended storage life of PP packed fruits compared to un-refrigerated fruits up to 14 days. Result of study revealed that Rambutan pre-packaging of rambutan in ventilated polypropylene (PP) reduced weight loss, while refrigerated storage extended storage life of PP packed fruits compared to un-refrigerated fruits up to 14 days. These results provide important information regarding the storage behavior of rambutan fruits and indicate that packaging and storage conditions are effective for reducing moisture loss and extending storage life of fresh rambutan fruit.

Women with cervical cancer, especially those with advanced disease, appear to experience suffering that is more prevalent, complex, and severe than that caused by other cancers and serious illnesses, and approximately 85% live in low- and middle-income countries where palliative care is rarely accessible. To respond to the highly prevalent and extreme suffering in this vulnerable population, we convened a group of experienced experts in all aspects of care for women with cervical cancer, and from countries of all income levels, to create an essential package of palliative care for cervical cancer (EPPCCC). The EPPCCC consists of a set of interventions, medicines, simple equipment, social supports, and human resources, and is designed to be safe and effective for preventing and relieving all types of suffering associated with cervical cancer. It includes only inexpensive and readily available medicines and equipment, and its use requires only basic training. Thus, the EPPCCC can and should be made accessible everywhere, including for the rural poor. We provide guidance for integrating the EPPCCC into gynecologic and oncologic care at all levels of health care systems, and into primary care, in countries of all income levels.

The essential package of palliative care for cervical cancer (EPPCCC), described elsewhere, is designed to be safe and effective for preventing and relieving most suffering associated with cervical cancer and universally accessible. However, it appears that women with cervical cancer, more frequently than patients with other cancers, experience various types of suffering that are refractory to basic palliative care such as what can be provided with the EPPCCC. In particular, relief of refractory pain, vomiting because of bowel obstruction, bleeding, and psychosocial suffering may require additional expertise, medicines, or equipment. Therefore, we convened a group of experienced experts in all aspects of care for women with cervical cancer, and from countries of all income levels, to create an augmented package of palliative care for cervical cancer with which even suffering refractory to the EPPCCC often can be relieved. The package consists of medicines, radiotherapy, surgical procedures, and psycho-oncologic therapies that require advanced or specialized training. Each item in this package should be made accessible whenever the necessary resources and expertise are available.

PURPOSE To enable design of optimum palliative care for women with cervical cancer, we studied the most common types of suffering and their severity, prevalence, and duration. METHODS We first reviewed the literature on the major types, severity, prevalence, and duration of suffering associated with cervical cancer. We then conducted a modified Delphi process with experts in cervical cancer care to supplement the literature. For each type of suffering, we distinguished between decedents (those who die from cervical cancer in a given year) and nondecedents (those who have cervical cancer in a given year but do not die). By applying the suffering prevalence and duration estimates to the number of decedents, nondecedents, and family caregivers in 2017, we were able to estimate their palliative care needs and the intensity of palliative care needed to respond adequately to this suffering. RESULTS There is a high prevalence among decedents of moderate or severe pain (84%), vaginal discharge (66%), vaginal bleeding (61%), and loss of faith (31%). Among both decedents and nondecedents, there is a high prevalence of clinically significant anxiety (63% and 50%, respectively), depressed mood (52% and 38%, respectively), and sexual dysfunction (87% and 83%, respectively). Moderate or severe financial distress is prevalent among decedents, nondecedents, and family caregivers (84%, 74%, and 66%, respectively). More than 40% of decedents and nondecedents are abandoned by their intimate partners. Most patients experience some combination of moderate or severe physical, psychological, social, and spiritual suffering. In total, 258,649 decedents and 2,558,857 nondecedents needed palliative care in 2017, approximately 85% of whom were in low- and middle-income countries where palliative care is rarely accessible. CONCLUSION Among women with advanced cervical cancer, suffering is highly prevalent and often severe and multifaceted.

A study was undertaken to evaluate the physiological and biochemical parameters and to quantify yield of twenty-two contrasting tomato genotypes when exposed to high temperature stress. Experiment was conducted in the Department of Plant Physiology, College of Agriculture, Vellayani during two growing seasons i.e., September to December, 2019 and March to June, 2020. The experiment was laid out in completely randomized design with two treatment levels i.e. control and high temperature stress (36+/-2oC) with three replications each under first season and 38+/-2oC during the second season. The high temperature stress was induced from flower initiation to maturity stage by keeping the pots in a temperature controlled green house facility for 45 days. The presence of stigma exertion, reduction in chlorophyll content and photosynthetic rate, reduced starch content and soluble sugar content, reduced chlorophyll fluorescence, low leaf membrane thermostabilty (LMT) were the major limitations for reproductive success and good yield. The correlation and regression analysis showed that yield under control conditions had strong positive correlation between LMT, pollen viability, photosynthetic rate, chlorophyll fluorescence, starch, soluble sugar and chlorophyll content. A negative correlation was observed between yield and stomatal conductance and transpiration rate. Under high temperature stress condition, all the parameters showed a positive correlation with yield. Based on the performances of various tomato genotypes under control and heat stress conditions, we were able to identify traits that could be manipulated to improve the high temperature tolerance in tomato.

Background: In brick kiln and construction industry the exposure to carbon monoxide and silica dust is the most common occupational hazard to the workers in these industries. A study on occupational health hazards of working women in these two unorganized sectors was undertaken by Lokmanya Medical Research Centre. Objectives: To study the effect of work site environment on the health of the women working in brick kiln and construction industry. An attempt was also made to study the seasonal changes in the concentration of carbon monoxide and dust at the worksite. Material and Methods: A cross-sectional study was conducted among the working women (age 18-40 years) at brick kilns and construction sites during summer and winter season. They were examined primarily to assess the effect of working environment on health. Gasteck Detector Pump of model 800 and air sampling instrument (SKC Air Check–52) were used to measure concentration of carbon monoxide and dust in the air respectively. Results: There were 66% of women who were in the age group of 18-40 years and most of them (94%) were married. At brick kiln sites, average CO exposure was 62.8 ppm and 55.5 ppm and average dust exposure was 3 3 146.1 mg/m and 91.4 mg/m in summer and winter season respectively.At construction sites, average dust exposure was 41.5 ppm and 90.8 ppm in summer and winter. Conclusion: Both exposure to CO and dust were more in summer than in winter in brick kiln industry whereas in construction industry the exposure to dust was more in winter season. A high level of morbidity in the form of headache, bodyache, problems with vision, cough and breathlessness were observed in both industries. It is strongly recommended to take pollution control measures.

Ninety landraces of rice were evaluated for various physio-morphological traits in completely randomized design with two treatment levels, i.e. control and high-temperature stress (3–5 °C) more than the ambient condition with three replications each. The high-temperature stress was induced from panicle initiation to maturity stage by keeping the pots in a temperature-controlled green house facility. High values of genotypic coefficient of variability, phenotypic coefficient of variability, heritability and genetic advance were found for the traits number of unfilled grains/panicle and number of filled grains/panicle, indicating the pre-ponderance of additive gene action and, therefore, scope for improvement of the trait through selection. Four principle components were depicted having Eigen value > 1 and cumulative variation of 59.84%. Based on the performances of various physio-morphological traits under control and heat stress conditions, we were able to identify Karuthacheera, LN-9956-Vellakaravala (Pavumba) and Pokkali white were recorded the highest number of fertile grains under high temperature.

Heat stress is an important abiotic stress affecting the productivity of tomato. Understanding the physiological basis of heat tolerance is needed to adapt to the current or future heat stress. Thus this study was undertaken to evaluate the phenology, physiology, biochemical and yield parameters of twenty-two contrasting tomato accessions when exposed to high temperature stress and to identify SSR markers associated with these traits. The experiment was laid out in completely randomized design with two treatment levels i.e. control and high temperature stress (36 ± 2 °C) with three replications each. The high temperature stress was induced from flower initiation to maturity stage by keeping the pots in a temperature controlled green house facility for 45 days. Twenty five SSR primers were employed to analyze genetic diversity and population structure among 22 tomato accessions collected from different eco-geographical regions of India. SSR markers proved to be more informative in genetic diversity assessment. These accessions showed significant genetic variability for physio-morphological and yield traits under both control and high temperature condition. Clustering by average linkage method was done to establish a relationship among the 22 tomato accessions. All the accessions were clustered into mainly three clusters. Principle component analysis revealed that, the first principal component revealed 43.39 per cent variation, while the second component showed 12.93 per cent variation under high temperature condition. Principle co-ordinate analysis evidently differentiated the accessions to three main groups based on genetic relatedness. Population structure analysis also obviously separated the accessions to four sub populations.GLM analysis identified 10, 9 highly significant marker traits association under high temperature and control condition respectively. Among them, RM270, SSR605 and RM356 were linked to more than one traits. Identified tolerant accessions and molecular markers can be utilized for developing high yielding high temperature tolerant tomato varieties in breeding programmes.

The effect of high-temperature stress has a critical impact in causing reduced crop yield. The focus of the current investigation is the identification of heat-tolerant rice varieties that can alleviate the effects of stress. Among the ten genotypes evaluated across various parameters such as leaf area, dry weight, photosynthetic rate, stomatal conductance and spikelet fertility, N-22 showed superior characteristics for the grain filling parameters along with CR-Dhan 307. The variety CR-Dhan 307 with significantly higher mean pollen viability (80.23%), spikelet fertility (81.18%) and 1000 grain weight (25.45 gm) can be utilized as a heat-tolerant variety. Other genotypes Ptb-7 and CR-Dhan 202 seemed to have tolerance traits beneficial at the vegetative stage. The genotype Rajalakshmi can be characterised as heat susceptible as it had significantly lower values for all parameters. Polymorphic analysis was carried out to validate SSR markers associated with heat tolerance. The polymorphic information content (PIC) was found to be the highest for RM236 and RM6100. The SSR marker RM6100 has been validated in the current investigation to be associated with heat tolerance. As the PIC value is an indication of the ability of the marker in indicating genetic diversity, the PIC values of the 11 polymorphic markers is useful for identify heat-tolerant genotypes. The genetic diversity analysis was carried out using DendroUPGMA to establish the relationship between the genotypes. The genotypes Ptb-7 and CR-Dhan 204 were thus found to be closely related to the heat-tolerant check variety, N-22 indicating genetically related traits for tolerance to heat.

It is essential to elucidate genetic diversity and relationships among related varieties of origin and landraces for improving the breeding process. Since rice breeding has improved agronomic traits such as yield and eating quality during green revolution, modern rice varieties are originated from narrow genetic resource and closely related. To resolve the population structure and genetic diversity in bold type rice varieties of southern India, we used a total of 81 rice genotypes by 100 simple sequence repeat markers composed of 36 improved varieties and 45 landraces, which are representative and important for bold type grain rice breeding. The landraces exhibit greater gene diversity than improved lines, suggesting that landraces can provide additional genetic diversity for future breeding. Clustering by Ward method was done to establish a relationship among the 81 rice genotypes. All the genotypes were clustered into mainly 5 clusters. Principle component analysis revealed that the first principal component revealed 42.87% variation, while the second component showed 14.01% variation. Among the eight morpho-physiological and plant production traits studied, the relative water content and spikelet fertility percentage contributed towards maximum diversity. Principle co-ordinate analysis evidently differentiated the genotypes to high yielding varieties with common ancestry. Population structure analysis also obviously classified the genotypes into high yielding susceptible and indigenous tolerant groups. These old varieties and landraces present in crop germplasm collections represent a strategic reserve of genetic variation that can be tapped for varieties and understanding of stress response and developing new varieties that are physiologically adapted to highly variable, climate-resilient environments.

General Energy - Abstract
At present plants had to face adverse climatic fluctuations which are often detrimental for their growth in order to cope up with this situation, they develop certain adaptive tactics like synthesis of new proteins, micro RNAs, compatible solutes/ osmolites and radical release to avoid its adverse effects. Of these study on compatible solutes such as polyamines (PAs) gained popularity among researchers. In plant, they are involved in a wide variety of regulatory and cellular processes under normal conditions. During these stresses they acts by activating biosynthesis of signaling molecules like NO, H2O2; affects abscisic acid synthesis; Ca2+ homeostasis; ion channel signaling or even apoptosis in severe conditions. Over expression of PAs is reported in various stresses due to the presence of stress-responsive elements in the promoters of PA biosynthetic genes. This review paper, summarizes the effect of polyamines in boosting plants growth during abiotic stress and its mechanisms of action.

Background: Cowpea is a leguminous crop of indeterminate growth habit and continues to produce flowers throughout its life cycle. In order to realize the genetic yield potential of cowpea, nutrient requirements of later formed flushes also needs to be met. Hence the present study was formulated to assess the effect of foliar application of water-soluble macro nutrient fertilizers viz., NPK 19:19:19 and potassium nitrate and micronutrient fertilizers viz. zinc sulphate and solubor for yield maximization in bush vegetable cowpea. Methods: The field experiment was conducted at Coconut Research Station, Balaramapuram, during Rabi 2020-21. The experiment was laid out in randomized block design with 13 treatments in three replications. The treatments comprised of recommended dose of conventional fertilizers (RDF) NPK 20:30:10 kg ha-1 as control and RDF + foliar application of water-soluble fertilizers 19:19:19 (0.5%) and potassium nitrate (0.5%) with zinc sulphate (0.05%) and solubor (0.025%) in twelve different combinations. Result: Results revealed that compared to RDF alone, RDF + foliar application of water-soluble macro and micro nutrient fertilizers at 45 DAS significantly improved the dry matter production, number of pods per plant and pod weight and recorded a yield enhancement of 22 to 55 per cent. Among the treatments, RDF + foliar application of 19:19:19 (0.5%) and solubor (0.025%) at 45 DAS recorded the highest dry matter production per plant (39.51 g), pods per plant (30.88 no.), pod yield (7410 kg ha-1), net return (82651 Rs ha-1) and B:C ratio (2.26). The treatments, RDF + foliar application of 19:19:19 (0.5%) at 45 DAS; RDF + foliar application of 19:19:19 (0.5%), zinc sulphate (0.05%) and solubor (0.025%) at 45 DAS; and RDF + foliar application of potassium nitrate (0.5%) and solubor (0.025%) at 45 DAS also recorded comparable number of pods per plant, green pod yield, net return and B:C ratio. Considering the highest green pod yield, net return and B:C ratio, RDF + foliar application of NPK 19:19:19 (0.5%) and solubor (0.025%) at 45 DAS could be recommended for yield maximization in bush type vegetable cowpea.
