The experiment was carried out at the Etay El-Baroud Experiment Station, El-Beheira Governorate, Egypt during the three successive seasons of 2014-2015, 2015-2016 and 2016-2017. The present study aimed at measuring the efficiency of two methods of selection used in the flax breeding program namely; pedigree method (PM) and bulk method (BM) on one flax population droved from previous work by the other (self) in 2014. F2 seed from the previous work furnished the source material for subsequent generations of flax populations (S2465/1 x Giza 8). In 2017 season, the high yielding selected lines (20) from each methods of breeding (two methods i.e. pedigree and bulk). Comparison between two breeding methods, mean square due to breeding methods were significant for days to flowering, No. of capsules / plant, length of fruiting zone, No. of seeds / capsule, seed index, seed yield /plant, technical stem length, and oil percentage. This result indicated the difference between breading methods. The pedigree methods gave the highest value for all traits. The pedigree method proved to be more efficient than bulk method for selection based on these traits may be due to the two parent good combiner for most traits. Also, gave the earliness of days to flowering. These result in this cross where a two parent were good combiner for most trait. For days to flowering, the result indicated that the pedigree method produced more superior lines than bulk method compared the best parent with fifteen and sixteen lines respectably. The best line was No. 7 of pedigree method. As for No. of capsule/ plant, 20 and 9 lines showed significant higher than best parent for pedigree and bulk method gave the highest number of capsules/ plant . Regarding to No. of basal branches/plant, the pedigree method produced consistently none superior parent compared the best parent, with three and four lines for pedigree and bulk, respectively. For No. of seeds / capsules, only the line No. 14 of pedigree method of breeding gave the highest no. of seeds / capsule. Concerning seed index, all lines of pedigree and bulk methods surpassed the best parent. Also, the line No. 9 of pedigree method gave the behavior seed index. With regard to seed yield/plant, four and six lines surpassed significant seed. Yield compare the best parent. The best line was No. 19 of pedigree followed by No. 2 of bulk method of breeding. For total length, sixteen lines of both breeding methods surpassed significant compare the best parent. The best line was No. 1 of pedigree method (123, 67). Regarding technical stem length, fourteen and nine lines showed significant higher than the best parent for pedigree and bulk methods, respectively the best line was No. 6 (112. 67) followed by No. 5 (111 . 33) of pedigree method . For fiber percentage, none of lines showed significant compare the best parent or over mean. [ABSTRACT FROM AUTHOR]

This investigation was undertaken at the Experimental Farm of the Faculty of Agriculture, Moshtohor, Benha University during the two summer growing seasons of 2018 and 2019. To estimate combining ability under two nitrogen levels and superiority% relative two check hybrids for five quantitative characters. N levels and genotypes mean squares were significant for all studied traits. Mean squares due to genotypes x N levels were significant obtained for all studied traits. SCA was higher than GCA for all studied traits revealing that the nonadditive effects were controlled these traits. The overall study of GCA effects suggested that parents M65, M66 and M48 were significant for general combiner for grain yield, M70 and M57 for earliness and M50 and M70 for short plants and ear stature. However, the genotypes M65xM10, M17xM10, M37xM10 and M48xCLM550 showed high SCA effect for grain yield plant-1. The maximum heterosis was recorded by the cross M48xCLM550 in combined across nitrogen levels they out-yielded SC128 and SC2031 reached 18.00 and 14.00%, respectively. 100-grain weight were correlated significantly with grain yield with r values being 0.707** in the combined analysis. Factor analysis for combined across N levels divided characters of maize into three factors accounted for 78.63% of the total variability. The first factor contributed by 39.14% included ear length, ear diameter, No. rows ear-1, No. kernels row-1, 100-kernel weight and shelling%. The second factor accounted for 24.83% and is mainly loaded by days to 50% tasseling and silking. The third factor accounted for 14.66% is mainly described by plant and ear heights.

Two field experiments were conducted at Moshtohor region, Kalubia Governorate, Egypt, during 2019/20 and 2020/21 seasons, to study the effect of three sowing dates (1st November, 15th November, 1st December) and three harvesting dates (Harvesting at 150 DAS after sowing, Harvesting at 165 DAS after sowing, Harvesting at 180 DAS after sowing) on yield and yield components of two barley cultivars (Giza 2000 and Bhoth 244). The experimental design was randomized complete block design using split split-plots arrangement with three replications. Sowing dates was arranged in the main plots and barley cultivars was arranged at random in the sub plots, while harvesting dates were arranged randomly by in the sub sub-plots. The main results were as follows: Sowing at 1st or 15th of November gave the highest values of all studied traits except spike length and harvest index in first season and plant height in second season. Meanwhile, Bhoth 244 cultivar gave the highest values of spike length, No. spikelets spike-1, spike weight, No. grains spike-1, grain yield fed-1 and straw yield fed-1, whereas Giza 2000 cultivar gave the highest values of plant height, 1000-kernel weight and harvest index in the first and second seasons. Harvesting at 150 DAS increased significantly spike weight, No. grains spike-1, 1000-kernel weight and straw yield fed-1 compared with the other harvesting dates, while spike length, No. spikelets spike-1, grain yield fed-1 and harvest index increased significantly by harvesting at 180 DAS in both seasons. Plant height, spike weight, No. grains spike-1, grain yield fed-1 and straw yield fed-1 were affected by the interaction between sowing dates and barley cultivars in both seasons except plant height in the second season and No. grains spike-1 in the first season. Moreover, plant height, spike length, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index were affected by the interaction between sowing dates and harvesting dates in both seasons except plant height, spike length, straw yield fed-1 and harvest index in the first season. While, plant height, No. spikelets spike-1, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index were affected by the interaction between barley cultivars and harvesting dates in both seasons except plant height, No. spikelets spike-1, grain yield fed-1, straw yield fed-1 and harvest index in the first season. Regarding the interaction effect, among sowing dates, barley cultivars and harvesting dates were significant differences of plant height, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index in both seasons except straw yield fed-1 and harvest index in the first season. It can be concluded that sowing Bhoth 244 cultivar in 1st or 15th November and harvesting at 180 DAS produced the height yield productivity under the conditions of this experiment.

Given the importance of the soybean plant in supplying the country's oil, Gelareh Kalhor Agriculture Company, in cooperation with the Ministry of Agricultural Jihad, imported 4 cultivars of soybeans resistant to heat stress from Brazil and evaluated them in various tests. The present plan has compared the yield and some yield components of imported cultivars with 4 internal cultivars. This experiment was laid out in the form of a randomized complete block design with three replications on a farm on the outskirts of Safi Abad Dezful Research Center in the summer and fall of 2022. For this purpose, imported cultivars including BRS284, BRS232, BRS391 and BRS511 were compared with internal cultivars of Caspian, Rahmat, Saland and SK93. The results showed the superiority of imported cultivars compared to internal cultivars in most traits. Group comparisons between imported and internal cultivars showed that in the traits of the average number of pods per plant, thousand seed weight and yield, imported cultivars were higher than internal cultivars by 20.5, 29 and 35% respectively. The first pod setting height which indicates the harvest efficiency with the combined machine in all imported cultivars was higher than 20 cm. The yield comparison between different cultivars showed that all the imported cultivars had a yield higher than 3000 kg. The highest yield was obtained from the BRS511 cultivar at the rate of 3853 kg, followed by BRS284 (3575 kg) and Caspian (3339 kg). Besides that, the results of the correlation test between different traits with yield showed that the yield has the highest correlation with the average weight of 1000-seed (71%) and with the number of pods per plant (57%). In general, the results of this research revealed that the imported cultivars have a high potential in terms of production and in the future, they can become popular cultivars among farmers.

Two field eхpеrimеnts were соnduсtеd аt the Experimental Farm, Faculty of Agriculture, Fayoum University at "Dar El-Ramad" Fayoum Governorate, Egypt during the summer growing seasons of 2019 and 2020. The main objective of this study was to determine the effect of sowing dates, ascorbic acid (vitamin C), zinc and their interaction on growth and yield of maize ( Zea mays L.). The experimental layout was a split- split plot arranged in randomized complete block design with three replications where sowing dates were considered as the main plot, ascorbic acid arranged in the sub plot and the sub-sub plot occupied by zinc foliar application treatments. Results indicated that sowing dates, ascorbic acid and zinc treatments hаd а signifiсаnt impасts оn yield and its attributes in the two seasons, except ear number per plant in two seasons and number of grains per row in the second season as well as 100 grain weight in the first season. Foliar spray of ascorbic acid treatments lеd tо signifiсаnt diffеrеnсеs in yield and its attributes i.e. number of ears/plant, ear length, ear dimeter, ear weight, number of row/ear, number of grains/row, ear grain weight, 100-grain weight and grain and biological yield/fed, as well as harvest index. The obtained data reveale also that the effect of zinc treatments on yield and its attributes was significant in the two seasons, except ear number per plant in two seasons and ear length in second season as well as number of grains/row in the first season.

Background: Knowledge about genetic parameters can help plant breeders to determine which selection criteria are beneficial. This study aims to estimate the genetic parameters of soybean seed characteristics. Metohds: A total of 91 soybean lines from three different populations were evaluated during dry season in 2016. All genetic material used was grown following a randomized complete block design with two replicates. Soybean pods were harvested after 90% of the leaves had yellowed or fallen. The characteristics of the seeds observed included length, width, thickness and weight of 100 seeds. Result: The results showed that there were two seed shapes (round and ellipse) and two seed sizes (large and medium). There is a broad genetic variability of soybean seed characteristics. Heritability broad sense varies from 0.42 to 0.84, classified as moderate (length-width ratio) to high (length, width, thickness, length-thickness ratio, width-thickness ration and weight of 100 seeds). This therefore shows that there is an opportunity to improve the characters of soybean seeds. The length, width, thickness, ratio of the three characters and the weight of 100 seeds can be used as selection criteria in a soybean breeding program to obtain large-seeded soybeans with a round or elliptical shape.

Excessive reliance on chemical fertilizer (CF) in conventional farming is a serious concern owing to its negative effects on soil health, the environment, and crop productivity. Organic manure is an alternative source of fertilizer to reduce the amount of CF usage in agriculture, decrease environmental pollution, and ensure sustainable crop production. This study assessed the integrated effect of poultry manure (PM) and cattle manure (CM) with CF on soil properties, plant physiology, and rice grain yield. Additionally, the difference in pre-and post-anthesis dry matter (DM) and nitrogen (N) accumulation and their relationship with grain yield was also determined. Pot experiments were performed in the early and late growing season at the experimental station of Guangxi University, China, in 2018. A total of six treatments, i.e., T1—CF0; T2−100% CF; T3−60% CM + 40% CF; T4−30% CM + 70% CF; T5−60% PM + 40% CF, and T6−30% PM + 70% CF were used in this pot experiment. Results showed that T6 enhanced leaf photosynthetic efficiency by 11% and 16%, chlorophyll content by 8% and 11%, panicle number by 12% and 16%, and grain yield by 11% and 15% in the early and late seasons, respectively, compared to T2. Similarly1, post-anthesis N and DM accumulation, N uptake, and soil properties (i.e., soil organic carbon, total N, and bulk density) were improved with integrated CF and manure treatments over the sole CF treatments. Interestingly, increases in post-anthesis N uptake and DM production were further supported by enhanced N-metabolizing enzyme activities (i.e., nitrate reductase, glutamine synthetase, and glutamate oxoglutarate aminotransferase during the grain-filling period in combined treatments. In-addition, the linear regression analysis showed that post-anthesis DM (R2 = 0.95) and N (R2 = 0.96) accumulation were highly associated with grain yield of rice. Thus, the combination of 30% N from PM or CM with 70% N from CF (i.e., urea) is a promising option for improvement of soil quality and rice grain yield. Furthermore, our study provides a sustainable nutrient management plan to increase rice yield with high N use efficiency. [ABSTRACT FROM AUTHOR]

The objective of this study was to determine the effect of phosphorus fertilizer rates, cultivar and location on drybean yield production at three different locations of North West province, South Africa. The experimental design was a 5 x 3 x 3 factorial experiment fitted into a randomized complete block design with 4 replications. The three drybean cultivars used were PAN 123, PAN 148 and PAN 9292. Three locations of the study were Taung, Ventersdorp and Mafikeng. The Five levels (0, 1, 2, 3 and 4) of phosphorus fertilizer were applied during planting and these differed according to each location. Drybean cultivar and location had significant effect (P < 0.005) on the number of pods per plant, 100- seed mass and grain yield. Drybean cultivar PAN 9292 is recommended for production due to its higher seed yield. [ABSTRACT FROM AUTHOR]

Nitrogen fixation by legumes like faba bean is a cheap way of fixing atmospheric nitrogen to plant available form. However, the inoculation of grain legumes with rhizobium bacteria along with the addition of micronutrients is poorly researched in Amhara Region of Ethiopia. Thus a study to examine the effects of rhizobium leguminosarum (var vicae) strains and micronutrients on nodulation, growth, and yield of faba bean was conducted in Wereillu district of Amhara Region, Ethiopia during the rainy season of 2018. The treatments comprised three faba bean strains (un-inoculated, EAL-1018, EAL-1035 and EAL-17) and two micro nutrients (without, zinc, boron) arranged in a randomized complete block design with three replications. The collected data on yield and yield-related parameters were analyzed using Statistical Analysis System (2003), version 9.1 and subjected to Duncan's Multiple Range Test for mean separation when the analysis of variance was significant. The mean separation revealed that the combined effect of EAL-1018 and boron brought significantly (P ≤ 0.05) higher difference on nodule number, nodulation volume, nodule dry weight, biomass yield and grain yield compared to the control. The combined effect of faba bean strain, EAL-1018 and boron gave 65.9% grain yield advantage over the control and 13.9% compared to the second promising treatment (EAL-1018 alone). Hence, EAL-1018 combined with boron is recommended for the study area and similar agro-ecologies. [ABSTRACT FROM AUTHOR]

A field experiment was carried out to evaluate the relative resistance of some soybean varieties against lima bean pod borer under field conditions in Giza Agricultural Experiments and Research Station (Lat. 30°00'30" N, Long. 31°12'43" E, 26 m a. s. l), ARC, Giza, Egypt during 2017 and 2018 summer seasons. The experiment included six soybean varieties (Giza 21, Giza 22, Giza 35, Giza 111, Crawford and Dr-101) and were distributed in randomized complete blocks design with three replications. It was observed that there was a significant difference in natural infestation of soybean varieties by lima bean pod borer. Soybean varieties Giza 35, Crawford and Giza 22 had higher infestation by the insect, meanwhile soybean variety Dr-101 showed a higher potential for resistance to lima bean pod borer where it recorded the lowest percentage of seed weight losses and the highest harvest index than the others in the two growing seasons. Seed storage proteins revealed variations among all soybean varieties under lima bean pod borer infestation. Soybean variety Dr-101 had higher resistance to lima bean pod borer where, it produced the highest number of protein bands (6 bands) for resistance to lima bean pod borer compared to the others. Soybean variety Giza 21 produced taller plants, but soybean variety Giza 35 had higher number of branches per plant, biological and straw yields per ha than the others. Although soybean variety Giza 22 was susceptible to lima bean pod borer infestation under field conditions, but this variety had higher pod pubescence length, pod and seed yields per plant, as well as, 100-seed weight than the others. Soybean varieties Giza 22 and Giza 111 gave higher seed yield per ha than the others in the two growing seasons. [ABSTRACT FROM AUTHOR]

Utilization of adequate fertilizer rate enhances soil physical and chemical properties, minimizes soil nutrient imbalance, and promotes better crop growth and development. The study investigated the influence of varying rates of chicken manure and NPK fertilizers as it affected growth, nutrient uptake, seed yield, and oil yield of sunflower on nutrient-limiting soil. Field experiments were carried out during 2014 and 2015 planting seasons for both main and residual studies. There were eight treatments comprising four rates of chicken manure (5, 10, 15, and 20 t·ha−1), three rates of NPK (30, 60, and 90 kg·N·ha−1), and control. The experiment was laid out in a randomized complete block design with three replicates. Growth, yield, dry matter and proximate, nutrient uptake concentration, and oil content were determined following standard procedures. Data were analyzed using ANOVA, and means were compared with the Duncan multiple range test (DMRT) at p≤0.05. Performance of sunflower was superior on the field fertilized with 10 t·ha−1 chicken manure which was comparable to 90 kg·N·ha−1 NPK fertilizer. Sunflower seed yield and oil quality were superior in plots supplied with 10 t·ha−1 chicken manure which was comparable to 60 kg·N·ha−1 NPK. Growth, yield, dry matter, and proximate content were least in the unfertilized plots. [ABSTRACT FROM AUTHOR]

The differences between theoretical yield levels and farmers' actual yields define the yield gaps. Soybean is an important global commodity. Therefore, the present study was performed to investigate of the role of pod abnormality incidence on yield and yield components of soybean in Aliabad Katul, Golestan Province, Iran. During the growing season of soybean cultivation (2016-17), 120 farms were selected with a different range of conditions and crop management, soil characteristics, and planting date. Selected farms were at a maximum radius of 10 km from the meteorological station. Abnormality percent (dysfunction syndrome in the R3 stage of soybean growth), yield and yield components, and seed oil and protein contents were evaluated at the end of the experiment. The results of simple correlation coefficients showed that there was a significant and positive correlation between yield and yield components as well as seed oil content. According to the analysis of regression, there was a significant effect of abnormality percent (as the dependent variable) on yield and yield components (as independent variables) except number of pods with one seed and seed protein content. The improvement of morphological and yielding traits resulted in a reduction in the abnormality percent. In some cases, the damage of pod abnormality caused 30% reduction in grain yield. In general, among environmental and agronomic factors, the number of days with temperature higher than 25 °C at flowering stage (5 days before and 10 days after flowering = R3 growth stage of soybean) had a significantly positive correlation with the abnormality percent. It can be concluded that crop management such as suitable planting date, cultivation of tolerant genotype, irrigation management especially at flowering stage, nutrition management, and others, can reduce the severity of the abnormality percent.

Two field experiments were carried out at Sidi Salem Directorate, Kafr EI-Sheikh Governorate, Egypt, during the two successive winter seasons of 2011/2012 and 201212013 to study the effect offour nitrogen fertilization rates (0, 37.5, 75 and 112.5 kg N/fed) and three phosphorous fertilization rates (0, 15 and 30 kg P2O5/fed) on the growth characters, yield, its component and some chemical properties of three bread wheat cultivars (Gemmeiza 9, Sakha 93 and Giza 168). The experimental design was split split plot design in four replications. The obvious results of this investigation can be summarized as follows: All traits of wheat under stUdy, i.e. No. of tillers/m2 , No. of spike/m2, plant height, spike length, No. of kernels/spike, 1000-kernel weight, kernels weigh/spike, straw yield/fed, grain yield/fed, biological yield/fed, harvest index, kernels nitrogen content (%) and grain protein yield/fed showed significantly increased by increasing nitrogen fertilizer rates, except kernels phosphorous content (%). Application of 112.5 kg N /fed significantly gave the maximum values of all traits. Increasing phosphorous fertilizer rates up to 30 Kg P2O5/fed significantly increased No. of tillers/m2, No. of spike/m2, plant height, spike length, straw yield/fed, grain yield/fed, biological yieldlfed and kernels phosphorous content (%) in the two seasons. While, No. of kernels/spike, 1000-kernel weight, kernels weight/spike, harvest index, kernels nitrogen content % and grain protein yield/fed were not affected by increasing phosphorous fertilizer rates. The results showed that wheat cultivars were significantly differed in all traits studied under study in the both seasons, except biological yield kg/fed, kernels nitrogen content (%) and kernels phosphorous content (%). Gemmeiza 9 cultivar significantly surpassed Sakha 93 and Giza 168 cultivars in plant height, spike length, 1000-kernel weight, kernels weight/spike, grain yield/fed, harvest index and kernels protein yield/fed in the both seasons, while, Sakha 93 recorded the highest values of No. of kernels/spike. Morever, Giza 168 surpassed the other two cultivars in No. of tillers/m2, No. of spike/m2 and straw yield/fed. The first order interactions between (112.5 kg N/fed X 30 Kg P2 O5/fed), (112.5 kg N/fed X Gemmeiza 9) and (30 Kg P2O5/fed X Gemmeiza 9) as well as the second order interaction between 112.5 kg N/fed X 30 Kg P2O5/fed X Gemmeiza 9 were significantly recorded the greatest grain yield/fed as compared with the others interactions in the both seasons. It could be summarized that sown wheat Gemmeiza 9 cultivar and fertilization by 30 Kg P2O2 + 112.5 kg N/fed maximized grain yield per unit area. [ABSTRACT FROM AUTHOR]

In the present investigation, twenty two elite breeding lines of black seeded soybean [Glycine max (L.) Merrill] were evaluated for 14 agro morphological traits during Kharif 2012 season. Among qualitative traits, presence of multifoliate leaf type was observed only in lines having moderate to high hundred seed weight and presence of anthocyanin pigment on hypocotyl was found related to violet flower colour in black seeded soybean lines. Among quantitative traits, grain yield per plant showed highly significant positive phenotypic and genotypic correlation with traits viz., dry matter weight per plant (0.95& 1.0) followed by 100 seed weight (0.75 & 0.87) and number of pods per plant (0.52 & 0.50). Path coefficient analysis also confirmed that traits viz., dry matter weight per plant and 100 seeds weight along with days to maturity can be considered as the key traits that can play a crucial role in the genetic improvement of black seeded soybean (bhat) genotypes for Uttarakhand hills.

A research was carried out to determine the role of Bacillus megaterium and soil pH in relation to phosphorus availability in soil using Sokoto Rock Phosphate. The experiment was laid out in completely randomized design (CRD) in the laboratory using three (3) treatments 0, 5 and 10ml of Bacillus megaterium replicated three times. The results obtained shows that there is no significance difference at (p<0.05) in phosphorus concentration in relation to inoculants and uninoculated treatments at 0ml, 5ml and 10ml using Phosphorus solubilizing bacteria, significant difference was only observed in relation to soil pH at 4th, 5th and 6th weeks after inoculation with the highest available phosphorus of 0.8gkg-1 at 4th week with a mean pH of 7.5. The study suggest that although, the trend and relative effectiveness of microorganisms in the soil are very complicated and unpredictable, the B. megaterium is not always effective at phosphorus solubilization as was observed in so many research elsewhere which may be affected by many factors, such as Phoshate Solubilizing Bacteria (PSB) used, nutritional status of soil and environmental factors. Therefore it was concluded that pH is important in improving the activities of phosphate solubilizing organisms. More research is needed to identify, screen and characterize more PSB for their ultimate application under field conditions. [ABSTRACT FROM AUTHOR]

Fifteen million farmers in India engaged in Maize cultivation. India would require 45 MMT of Maize by 2022. But, only 15% of cultivated area of maize is under irrigation and water shortage has been a challenge for sustainability of maize production. Water deficit stress (WDS) during pre-flowering and grain filling stages massively affects the plant performance due to imprecise traits function. Thus, the effect of WDS on non-drought tolerant (NDT) and drought tolerant (DT) maize lines were investigated. WDS increased the flowering days, days to maturity, anthesis silk interval, decreased the leaf number, abnormal expression of secondary stress responsive traits, loss of normal root architecture which overall lead to a reduction in GY/ha. WDS at flowering and grain filling stage leads to significant yield penalty especially in NDT lines than DT lines. The yield penalty was ranged from 34.28 to 66.15% in NDT and 38.48 to 55.95% in DT lines due to WDS. Using multiple statistics, traits which improve WDS tolerance in maize were identified viz; number of leaves, number of stomata on lower surface of leaf, leaf angle at ear forming node internodal length between 3 rd and 4 th leaf from top, flag leaf length, flag leaf width, ear per plants, leaf senescence, pollen stainability, root fresh weight and root length. These traits would help in trait specific breeding in maize for WDS tolerance.
