Ammonia (NH3) volatilization from NH3-based fertilizer and animal manure reduces their nitrogen (N) fertilizer value and is a source of environmental pollution. Mixing manure with biochar may lower NH3 volatilization from manure by adding H+, adsorbing mineral N, or increasing N immobilization in microbial biomass. The objective of this study was to determine whether wood-based biochar could lower NH3 volatilization from vented pails containing manure (liquid swine, dairy slurry, and solid poultry manure) or a urea ammonium nitrate solution (UAN). Two types of wood-based biochar (BlueLeaf and Dynamotive) were mixed with three types of manure and UAN fertilizer solution at 0, 2.5, 5, 10, and 25% biochar by volume in vented pails. After 21 d storage in an outdoor shaded area, the greatest NH3 volatilization was from poultry manure, which had pH 9.4 on average and low water content regardless of the biochar source and application rate. There was less NH3 volatilization from UAN fertilizer solution when mixed with 25% (v/v) of Dynamotive biochar compared with NH3 volatilization from UAN fertilizer solution mixed with 0%–10% (%) of Dynamotive biochar, probably because pH decreased from 7.0 to 6.4 after 21 d contact. Mixing wood-based biochar with manure had no impact on NH3 volatilization, suggesting that these biochar sources did not appreciably change the pH and N dynamics in stored manure after 21 d.

In spite of the rapid progress in the field of medicine, humanity still striving for cure of diabetes, a disorder of metabolism. From literature study it is inferred that no one therapeutic agent is isolated and/ or synthesized to treat diabetes, but to manage the disease. Therefore, it is of much importance to address this medical issue with phytochemical synergism for boosting immunity and limiting the severe side effects of synthetic hypoglycemic agents. The antioxidant and hypoglycemic effects of black seeds and chickpea have been determined previously, however the combined hypoglycemic effect of these seeds has not been studied until now. In present study the combined methanolic extract (CME) of Nigella sativa (black cumen) and Cicer arietinum (chickpea) seeds has shown the significant antioxidant potential as revealed by its significantly reduced IC50 value for radical scavenging activity in DPPH assay (-36.39%, p0.05) increase (2.12%) in observed body weights, however, showed the significant decrease in blood glucose levels (-42.24%, p

The current study investigates the antioxidant, antidiabetic, hepatoprotective, and nephroprotective potentials of a polyherbal mixture containing the methanolic extracts of seeds from

Varied floristic works relevant to Kashmir Himalaya were thoroughly examined to compile taxonomic contributions of various taxonomists viz. a viz. diversity in gymnosperms of this region. Extensive field surveys and standard taxonomic methods were used to locate, collect, identify and prepare an updated list of the target group. A total of 25 species of gymnosperms belonging to 13 genera in 6 families and 4 orders have been documented from the Kashmir Himalaya. Wild gymnosperms are represented by 11 species with conifers forming the most dominant group. Among families, Pinaceae is highest represented with 6 species, while Taxaceae is least represented. Cultivated gymnosperms exceed wild growing species, and Cupressaceae is most dominant with 9 species whereas Ginkgoaceae is least represented. Out 25 species 19 (7 wild + 12 cultivated) are trees, 5 (3 wild + 2 cultivated) are shrubs and only 1 is sub-shrub.

As reported recently by the present authors, vermicomposting by the epigeic earthworm Eisenia fetida transforms the highly ligninous and allelopathic aquatic weed salvinia (Salvinia molesta) into a benign organic fertilizer. The present study was carried out with four other earthworm species, including three epigeic species of different sizes and phytophagic habits: Eisenia andrei, Lumbricus rubillus, and Perionyx sansibaricus. One anecic species, with geophytophagous habits, was also explored for comparison: Drawida willsi. The objective was to see whether the type of salvinia transformation caused by E. fetida is a general phenomenon or whether there are significant differences in the nature of biocomposts generated by different earthworm species. Accordingly, the characteristics of the biocomposts separately generated by each of the six species mentioned above were assessed with UV-visible spectrophotometry, Fourier-transform infrared spectrometry, differential scanning calorimetry, thermogravimetry, and scanning electron microscopy. The studies reveal that, with minor variations, the biocomposting by all four species was able to remove the intransigence of salvinia and impart plant/soil-friendly attributes to it in substantial measures. All the findings obtained with different techniques corroborated each other in arriving at this conclusion. Hence, it can be said that, in general, biocomposting by earthworms takes away the toxicity of pernicious weeds such as salvinia, converting them into plant-friendly and soil-friendly biofertilizers.

Purpose: To evaluate the antidiabetic, hypolipidemic and antioxidant potential of seed oil of Nigella sativa L (NSO). Methods: Nigella sativa seed oil (NSO) was extracted with Soxhlet apparatus using petroleum ether, and was given orally at a dose of 2.5 ml/kg body weight to alloxan-induced diabetic rabbits daily for 24 days. Biochemical parameters including total cholesterol (TC), triglycerides (TGs), low density lipoprotein cholesterol (LDL), very low lipoprotein cholesterol (VLDL), high density lipoprotein (HDL) and plasma glucose were determined in the treatment and control groups. Furthermore, bilirubin, vitamin C, catalase and mean body weight were assessed. Results: NSO treatment significantly lowered serum blood glucose levels and lipid contents, but increased the mean body weight, HDL-C and vitamin C levels of diabetic rabbits (p < 0.001). Moreover, NSO significantly decreased catalase activity, TC, TGs, LDL-C and VLDL-C levels, but normalized bilirubin levels in diabetic rabbits. Conclusion: These results indicate that NSO possesses significant antidiabetic potential. Thus, it may be useful as an adjunct with antidiabetic medication but further studies are required to ascertain this. Keywords: Black cumin, Diabetes, Hypoglycemic, Hypolipidemic, Antioxidants

Surface runoff from agricultural fields is the largest non-point source of phosphorus (P) that pollutes surface water in humid temperate regions. Best management practices have attempted to reduce P loading and improve P retention in agricultural soils, but significant losses continue to occur, emphasizing the need for novel solutions. The objective of this study was to determine whether wood-based biochars applied to an agricultural field, 3 years earlier, could reduce P loss in surface runoff by increasing water infiltration or by improving soil stability. Field plots amended with Dynamotive, Basques and Pyrovac biochars (5 and 10 t ha−1) or without biochar were subjected to 30-min of simulated rainfall to determine runoff volume, time-until-ponding, infiltration rate, and water holding capacity, as well as the P concentration and P load in runoff. The distribution of soil macro- and micro-aggregates and their total organic C and total P content was measured. Soil water dynamics were not affected by biochar amendments, however, runoff contained significantly less ortho-P in field soil amended with Dynamotive and Basques biochar at 5 t ha−1 and significantly less particulate P when amended with biochar at 10 t ha−1. Biochar-amended soil had significantly greater microaggregate stability, organic C and total P content than the control soil without biochar. The reduction in particulate P concentration in runoff may be the result of biochar integration within the microaggregate structure, which indirectly promotes P retention in macroaggregates.

Background: Indian Himalayan region has a rich heritage of species and genetic strains of flora and fauna and is considered as mega hot spot of biological diversity. Wild plant raw material is in great demand around the world for use by pharmaceutical companies, ethnomedicinal practitioners and variety of traditional medicines. India is one of the world’s major exporters of raw herbal drugs and the Himalayas are renowned for their vast storehouse of medicinal plants. The present study conducted at Baba Ghulam Shah Basdshah University located in District Rajouri, Jammu and Kashmir recorded the presence of 46 species of medicinal plants belonging to 34 families.

The design and testing of a novel vermicomposting system, acronymed FLUVTS ─ FLippable Units Vermireactor Train System ─ is presented. It enables rapid vermicomposting of paper waste without the need of pre-composting and requires animal manure supplementation to the extent of only 10:1 paper: manure mass ratio in contrast to reported systems which must have 50% or more of the feed mass as animal manure. Moreover, the system enables the vermicomposting to be accomplished at a high rate, achieving near-total convertion of feed to vermicast at solid retention times of just 30 days in comparison to conventional systems which take 90–120 days for the same process. Uninterrupted vermireactor operation for 6 months, during which the feed was put in and its vermicompost harvested once in 30 days, demonstrates the robustness and the consistency of the system. The suitability of the paper-waste vermicompost as an organic fertilizer was then tested in terms of it's effect on seed germination and early growth of four food plants chilly (Capsicum annuum), ladies finger, (Abelmoschus esculentus), cucumber (Cucumis sativus), and tomato (Lycopersicon esculentum). In general, the paper waste vermicompost when applied at levels

Utilization of Salvinia molesta, an aquatic weed which is notorious for its allelopathy and invasiveness, has been explored by its vermicomposting. Fourier transform infrared spectroscopy (FT-IR) and plant bioassay tests were conducted to analyze the composition and fertilizer value of S .molesta vermicompost. Germination and seedling growth tests were performed in soil supplemented with vermicompost at levels ranging from 0.75 to 40% by weight of the soil on three common food plants, ladies finger (Abelmoschus esculentus), cucumber (Cucumis sativus), and green gram (Vigna radiata). The influence of S. molesta's vermicompost on some of the physicochemical and biological attributes of the soil was also studied. FT-IR analysis revealed that S. molesta loses its allelopathy, as the chemical compounds that are responsible for it are largely destroyed, in the course of its vermicomposting. There is also an indication that a portion of lignin content of S. molesta is degraded. Vermicompost enhanced the germination success and promoted the morphological growth and biochemical content of the plant species studied. It also bestowed plant friendly physicochemical and biological attributes to the soil. The findings raise the prospect that billions of tons of S. molesta biomass-which not only goes to waste at present but is also a cause of serious harm to the environment-may become utilizable in organic agriculture.

Purpose In a novel attempt, vermicompost derived from an intransigent and noxious weed salvinia was assessed for its fertilizer value and pest repellent properties. Methods In outdoor experiments which simulated the way vegetables are cultivated by farmers, ladies finger (Abelmoschus esculentus) seeds were germinated and grown in soil supplemented with salvinia vermicompost at four levels: 0 (V0), 2.5 (V1), 3.75 (V2) and 5 (V3) t/ha. Besides assessing germination success and subsequent growth, yield, and biochemical content of the plants, the impact of pest attacks on them was also studied. Results Salvinia vermicompost significantly enhanced germination success, growth, and yield of the plants. Maximum growth in terms of shoot length (96.2 cm), root length (48.2 cm), shoot and root dry weight (23.31, 7.96 g), stem diameter (14.04 mm), and number of leaves and branches (26.8, 4.8) was recorded in V4 (5t/ha). Likewise, the mineral and biochemical content in vermicompost-treated plants was significantly higher than in the controls. The vermicompost also induced resistance in plants against pests and disease. Compared to the controls, vermicompost had reduced the fruit borer infection by 65, 78 and 82% in V1, V2 and V3, respectively. Conclusion The toxicity of salvinia is largely eliminated when it is vermicomposted, and the product acquires the qualities of a good organic fertilizer. The present work can potentially lead to the development of an inexpensive, sustainable and eco-friendly method of utilizing billions of tons of phytomass that is generated annually by salvinia, and which presently goes to waste.

The composition and the fertilizer value of vermicompost derived solely from ipomoea, a weed known for its toxicity and allelopathy, has been studied employing Fourier transform Infrared Spectroscopy (FT-IR) and plant bioassay (germination and seedling growth). The impact of ipomoea’s vermicompost on the physicochemical and biological characteristics of the soil was also studied. FT-IR analysis revealed that chemical compounds that are responsible for the deleterious effect of ipomoea are largely destroyed in the course of ipomoea’s vermicomposting. The ipomoea vermicompost was seen to be a good organic fertilizer as it significantly enhanced germination success, promoted growth of the seedlings and induced plant friendly physicochemical and biological features to the soil. The studies raise the possibility that very large quantities of biomass that are generated by ipomoea across the world can be utilized in producing organic fertilizer through vermicomposting. This may also provide a means of checking the seemingly unstoppable spread of ipomoea and cushioning its adverse impacts.

The study objective was to discover if carvedilol enhanced constructive and functional variations in the left ventricle and decreased mortality within patients with hypertensive heart disease. The parameters of echocariography, blood pressure, heart rate, and research variables were evaluated pre and post therapy with carvedilol in 98 qualified patients. At a median 50 milligram dose per day, carvedilol, in between the period of treatment in hypertensive heart disease reduced blood pressure level 10/10 mmHg, heart rate 10 beats/min, enhanced left ventricular ejection fraction from standard to follow-up (median: 6 years) (36%–47%)) and decreased left ventricular end-diastolic and end-systolic proportions (62 vs 56 mm; 53 vs 42 mm, respectively, all p-values Carvedilol decreased cardiac dimensions and enhanced left ventricular ejection fraction and cardiac renovating in patients with hypertensive heart disease. These types of treatment-related variations possessed an advantageous impact on the rate of survival. Keywords: Left ventricular reverse remodeling, beta-blockers, hypertensive heart disease, ejection fraction, survival.

Nonspecific binding of monoclonal antibodies (mAbs) to Fc-receptors on leukocytes is an important cause of background fluorescence in flow cytometry, and failing to block such nonspecific binding can lead to erroneous results. A major part of previous studies on blocking reagents for flow cytometry have been done in mice, and published results are not completely in agreement. In humans, Fc-receptors are found on most leukocytes, with highest abundance on monocytes/macrophages. Therefore, in the present study our aim was to thoroughly investigate the efficiency of different commonly used blocking reagents regarding inhibition of nonspecific binding of mouse mAbs to human peripheral blood mononuclear cells (MNCs) and monocyte-derived macrophages (MDMs). Monocytes and MDMs showed strong nonspecific binding of IgG1 and IgG2a isotypes, but not IgG2b. In contrast, B-cells, T-cells, and NK-cells did not substantially bind any of the mouse isotype control antibodies evaluated (IgG1, IgG2a, and IgG2b). Importantly, we show that binding of IgG1 and IgG2a to monocytes and MDMs can be eliminated by blocking, either with a commercial Fc-blocking reagent, with mouse or human serum, or with mouse or human IgG in high concentration. Previously, isotype controls have been widely used in flow cytometry assays. However, we show that such controls may be highly unreliable, and we believe they should not be used as gating controls, or to determine background signal. Based on these results, as well as considerations of price and applicability, our recommendation is not to use isotypes as gating controls in flow cytometry, but instead to use 100 μg/mL of purified human IgG as blocking reagent for elimination of nonspecific binding of mouse mAbs to human MNCs and MDMs. © 2016 International Society for Advancement of Cytometry

Characteristics of the highly pernicious weed ipomoea ( Ipomoea carnea ) were studied before and after its vermicomposting by the earthworm ( Eisenia fetida ). The studies, supported by UV–visible and Fourier transform infrared spectroscopy (FT-IR), thermogravimetric (TG) and differential scanning calorimetry (DSC), gas chromatography–mass spectrometry (GC–MS), and scanning electron microscopy (SEM) reveal a drastic change in the characteristics. There was a sharp reduction in the carbon-to-nitrogen ratio from 26.1 to 9.9, and in humification index from 7.7 to 1.9. By all accounts there was substantial mineralization of organic matter. Complex aromatics such as lignin and polyphenols were degraded into simpler carbohydrates and lipids. GC–MS analysis showed significant fragmentation, bio-oxidation and molecular rearrangements of chemical compounds in vermicompost in comparison to those in ipomoea. SEM micrographs of ipomoea vermicompost reflected strongly disaggregated material compared to ipomoea. The phenols and alkaloids which are specifically responsible for the toxicity and allelopathy of ipomoea, were significantly degraded in the course of the weed's vermicomposting, turning it into a plant-friendly organic fertilizer. These findings make it appear possible that millions of tons of ipomoea biomass, which is generated annually but goes to waste, can be transformed into organic fertilizer.

Vermicompost, which had been derived solely by the action of the epigeic earthworm Eisenia fetida on parthenium (Parthenium hysterophorus), was tested for its impact on the germination and early growth of green gram (Vigna radiata), ladies finger (Abelmoschus esculentus) and cucumber (Cucumis sativus). Seedlings were germinated and grown in soil amended with 0 (control), 0.75, 1.5, 2, 4, 8, 20 and 40% (by weight) parthenium vermicompost. Even though parthenium is known to possess strong negative allelopathy, as also plant/animal toxicity in other forms, its vermicompost (VC) manifested none of these attributes. Rather the VC enhanced germination success, introduced plant-friendly physical features in the container media, increased biomass carbon, and was seen to promote early growth as reflected in several morphological and biochemical characteristics in plants which had received parthenium VC in comparison to those which had not. All these effects were statistically significant. Fourier Transform Infrared (FTIR) Spectrometry revealed that the phenols and the sesquiterpene lactones that are responsible for the negative allelopathic impact of parthenium were largely destroyed in the course of vermicomposting. FTIR spectra also indicated that lignin content of parthenium was reduced during its vermicomposting. The findings open up the possibility that several other invasives known for their negative allelopathy and toxicity may also produce vermicompost which may be plant-friendly and soil-friendly. It also makes it appear possible that the huge quantities of phytomass that is generated annually by parthenium can be gainfully utilized in producing organic fertilizer via vermicomposting, thereby providing a means of exercising some control over parthenium's rampant growth and invasion.

In what is believed to be the first study of its kind, the compositions of the toxic and allelopathic weed parthenium, and its vermicompost, have been investigated using UV–visible and Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, gas chromatography–mass spectroscopy, and scanning electron microscopy. The studies reveal that the weed is transformed into a totally benign organic fertilizer during the course of its vermicomposting. This is indicated by substantial improvements in the humification index, mineralization of organic matter, and degradation of complex aromatics such as lignin and polyphenols into simpler carbohydrates and lipids when parthenium is turned into its vermicompost. There are also significant fragmentation, bio-oxidation and molecular rearrangements of chemical compounds in parthenium vermicompost compared to the parent substrate. In particular, parthenin, which is principally responsible for the toxicity and allelopathy of par...

In evidently the first study of its kind, vermicompost derived solely from salvinia (Salvinia molesta Mitchell), arguably the world’s most invasive and dominant aquatic weed, has been assessed for its nature and composition. Salvinia is known to contain exceptionally high concentrations of polyphenols, and has unusually ligneous leaves—the two attributes that make it strongly allelopathic and hardy, enabling it to elbow out other vegetation. The present study, supported by UV–vis and FTIR spectrometry, thermogravimetric and differential thermal analysis, and GS-MS analysis, reveals that upon vermicomposting salvinia loses its allelopathy. It happens because chemicals responsible for the alleopathy of salvinia are destroyed, transforming the weed into a potent organic fertilizer. Much of the salvinia’s lignin is also biodegraded. Scanning electron microscopy shows marked disaggregation of the material in the vermicompost as compared to well-formed matrix of salvinia leaves. The findings open up the possibility of utilizing billions of tonnes of salvinia biomass – which not only goes to waste at present but is also a cause of serious harm to the environment – in making organic fertilizer.

Microscopic plant parasitic nematodes are round worms that feed on plants and damage them. The most common and serious amongst the nematodes is the root-knot nematode found throughout the country with a very wide host range of cultivated crops. Brinjal (Solanum melongena) crop yield is considerably reduced by root-knot nematodes particularly Meloidogyne incognita. Root-galls of brinjal caused by Meloidogyne incognita can be controlled effectively by using the bio-agents and botanicals which in turn increases the yield and plant growth. Present study explored the effect of leaf extracts of certain plants on the root-knot development, plant growth and nematode multiplication in pot experiments. Extract treated and nematode inoculated plants showed improvement on growth over untreated inoculated plants and reduced the disease development. Five (viz., margosa, marigold, datura, hemp and tobacco) leaf extracts, irrespective of concentration, apparently induced tolerance in inoculated plants as evidenced by better plant growth in comparison to control and suppressed the multiplication of nematode which resulted in low root-knot index. Margosa (Azadirachta indica) leaf extract suppressed the nematode multiplication, reduced root galling and improved the plant growth of inoculated plants. Margosa and marigold (Tagetes erecta) leaf extracts were found more effective in controlling the root-knot development than the leaf extracts of hemp (Cannabis sativa), datura (Datura metel) and tobacco (Nicotiana tabacum). Higher concentrations (20 ml/plant) of leaf extracts were found to be more effective in controlling the root knot development. Based on our observations, it may be concluded that margosa or marigold extract treatment of brinjal seedlings prior to transplantation can avoid severe damage by suppressing the nematode multiplication and inducing the tolerance in treated inoculated plants.

In evidently the first study of its kind, vermicompost derived solely from a weed known to possess plant and animal toxicity was used to assess its impact on the germination and early growth of several plant species. No pre-composting or supplementation of animal manure was done to generate the vermicompost in order to ensure that the impact is clearly attributable to the weed. Whereas the weed used in this study, Lantana (Lantana camara), is known to possess strong negative allelopathy, besides plant/animal toxicity in other forms, its vermicompost was seen to be a good organic fertilizer as it increased germination success and encouraged growth of all the three botanical species explored by the authors - green gram (Vigna radiata), ladies finger (Abelmoschus esculentus) and cucumber (Cucumis sativus). In terms of several physical, chemical and biochemical attributes that were studied, the vermicompost appeared plant-friendly, giving best results in general when employed at concentrations of 1.5% in soil (w/w). Fourier transform infrared spectrometry revealed that the phenols and the sesquiterpene lactones that are responsible for the allelopathic impact of Lantana were largely destroyed in the course of vermicomposting. There is also an indication that lignin content of Lantana was reduced during its vermicomposting. The findings open up the possibility that the billions of tons of phytomass that is generated annually by Lantana and other invasives can be gainfully utilized in generating organic fertilizer via vermicomposting.

In this paper an attempt has been made to understand the patterns and determinants of crop diversification in Jammu and Kashmir agriculture. Entropy index has been applied to explore the extent of diversification or specialization across crops and districts. Entropy indices of diversification and Gross Cropped Area (GCA) under non-foodgrains were regressed on different explanatory variables. The study revealed that the crop sector of Jammu and Kashmir agriculture at an aggregate level is gradually diversifying in favour of high-value crops. However, while analyzing the extent of diversification at regional level, the Jammu division is witnessing a specialization in foodgrain crops, whileas Kashmir division depicting a trend towards diversification.Further, an analysis of determinants that facilitated the process of crop diversification revealed all the factors considered under study have significantly affected crop diversification in the state, except fertilizer consumption.

Fused real-time ultrasound and magnetic resonance imaging (MRI) may be used to improve the accuracy of advanced image guided procedures. However, its use in regional anesthesia is practically nonexistent. In this randomized controlled crossover trial, we aim to explore effectiveness, procedure-related outcomes, injectate spread analyzed by MRI, and safety of ultrasound/MRI fusion versus ultrasound guided Suprasacral Parallel Shift (SSPS) technique for lumbosacral plexus blockade. Twenty-six healthy subjects aged 21–36 years received two SSPS blocks (20 mL 2% lidocaine-epinephrine [1 : 200,000] added 1 mL diluted contrast) guided by ultrasound/MRI fusion versus ultrasound. Number (proportion) of subjects with motor blockade of the femoral and obturator nerves and the lumbosacral trunk was equal (ultrasound/MRI, 23/26 [88%]; ultrasound, 23/26 [88%];p=1.00). Median (interquartile range) preparation and procedure times (s) were longer for the ultrasound/MRI fusion guided technique (686 [552–1023] versus 196 [167–228],p<0.001and 333 [254–439] versus 216 [176–294],p=0.001). Both techniques produced perineural spread and corresponding sensory analgesia from L2 to S1. Epidural spread and lidocaine pharmacokinetics were similar. Different compartmentalized patterns of injectate spread were observed. Ultrasound/MRI fusion guided SSPS was equally effective and safe but required prolonged time, compared to ultrasound guided SSPS. This trial is registered with EudraCT (2013-004013-41) and ClinicalTrials.gov (NCT02593370).

In perhaps the first-ever study of its kind, the effect of vermicompost, derived solely from an allelopathic weed, on the germination, growth, and yield of a botanical species, has been carried out. In test plots, the soil was treated with the vermicompost of lantana (Lantana camara) at the rates of 5, 7.5, and 10 t ha(-1), and cluster bean (Cyamopsis tetragonoloba) was grown on it. The performance of these systems was compared with the systems in which the soil was fortified with inorganic fertilizers (IFs) in concentrations equivalent to those present in the respective vermicompost (VC) treatments. Additionally, a set of control was studied in which the soil was used without fortification by either VC or IF. It was seen that up to 51.5 % greater germination success occurred in the VC treatments compared to controls. VC also supported better plant growth in terms of stem diameter, shoot length, shoot mass, number of leaves, and leaf pigments. The positive impact extended up to fruit yield. In addition, vermicast application enhanced root nodule formation, reduced disease incidence, and allowed for a smaller number of stunted plants. The results indicate that allelopathic ingredients of lantana seem to have been totally eliminated during the course of its vermicomposting and that lantana vermicompost has the potential to support germination, growth, and fruit yield better than equivalent quantities of IFs.

Vermicomposting is a process in which earthworms are utilized to convert biodegradable organic waste into humus-like vermicast. Past work, mainly on vermicomposting of animal droppings, has shown that vermicompost is an excellent organic fertilizer and is also imbibed with pest-repellent properties. However, there is no clarity whether vermicomposts of organic wastes other than animal droppings are as plant-friendly as the manure-based vermicomposts are believed to be. It is also not clear as to whether the action of a vermicompost as a fertilizer depends on the species of plants being fertilized by it. This raises questions whether vermicomposts are beneficial (or harmful) at all levels of application or if there is a duality in their action which is a function of their rate of application. The present work is an attempt to seek answers to these questions. To that end, all hitherto published reports on the action of vermicomposts of different substrates on different species of plants have been assessed. The study reveals that, in general, vermicomposts of all animal/plant based organic wastes are highly potent fertilizers. They also possess some ability to repel plant pests. The factors that shape these properties have been assessed and the knowledge gaps that need to be bridged have been identified.
