A field experiment on okra taking the variety BARI Dharos-1 with four nitrogen levels (0, 75, 125 and 175 kg/ha) and six levels of green fruit picking (no green fruit picking, first two, first four, first six, first eight and first ten green fruit picking) was conducted at the Agricultural Research Station, Raikhali, Rangamati Hill District to find out the optimum N level and suitable number of green fruit picking during the summer seasons of 2005 and 2006 for the highest economic benefit. The plants were grown for both vegetable and seed production. Growth parameters, green fruit as well as dry fruit characters, seed yield attributes were significantly affected by different levels of N and green fruit picking. Nitrogen levels and green fruit picking increased number of dry fruits per plant, number of seeds per fruit, weight of seeds per fruit and seed yield. Application of N @ 125 kg/ha gave the highest fruit and seed yield of okra followed by 175 kg N/ha. These two N levels also produced maximum 100-seed weight, percentage of germination and seed vigour. The treatment of picking of 10 green fruits produced the highest green fruit yield/ha. But picking of first 4 green fruits produced maximum seed yield, which was statistically at par with those of 2 and 6 green fruits picking. First 4 green fruit picking gave the highest seed vigour whereas first 6 green fruit pickings produced maximum 100-seed weight. Picking of first 4 green fruits accompanied with 175 kg N/ha gave the highest seed yield of 2.86 t/ha, which was closely followed by picking of first 2 or 6 green fruits with 125 kg as well as 175 kg N/ha. Picking of first 2 or 4 green fruits in combination with 125 kg N/ha also gave the similar seed yield. The combination of 125 kg N/ha and first 6 green fruit picking gave the highest gross income (Tk.193.56/ha), net return (Tk.126.35/ha) and maximum BCR of 2.88. Key words: Nitrogen; picking; okra; fruit and seed yield; profitability. DOI: 10.3329/jard.v7i1.4428 J Agric Rural Dev 7(1&2), 99-106, June 2009

High yielding varieties and suitable sowing time are the most important factors affecting the mungbean yield. Field experiments were carried out during kharif 2013 and 2014 at Dryland Agricultural Research Station, Budgam, Sher-e-Kashmir University of Agricultural Sciences and Technology Kashmir, India to find out the suitable genotype of mungbean under delayed sowing conditions. The early sowing (first fortnight of June) recorded higher yield contributing characters ( seeds/plant and 100 seed weight) and seed yield than delayed sowing. Among genotypes ‘SKUA-M-365’ recorded higher 100-seed weight and seed yield in early sowing as well as under delayed sowing conditions.

Abstract The present investigation was carried out to evaluate agronomic performance and oil quality of seven sunflower genotypes at Shandaweel Research Station, Agricultural Research Center, Sohag, Egypt during 2018 and 2019 summer seasons. These genetic materials were sown in a randomized complete block design having three replications. Significant genetic variations among evaluated sunflower genotypes for agronomic traits and oil quality were observed. The superior sunflower genotypes were Line 120 for seed yield per hectare (3102.38 kg), Sakha 53 for seed oil content (44.63 %) and Line 125 for oil quality where it contained the highest proportion of unsaturated fatty acids (89.20 %). The phenotypic coefficients of variation were slightly higher than genotypic coefficients of variation for all studied traits. High heritability (exceeded 60%) and genetic advance as percent of mean (ranged from medium to high, exceeded 10%) was observed for most studied traits. Seed yield per plant positively correlated with plant height, stem diameter, head diameter, and 100-seed weight and most chemical traits at phenotypic and genotypic levels. Maximum phenotypic direct effects on seed yield per plant were observed for 100-seed weight, head diameter and total unsaturated fatty acids. While, the highest genotypic direct effect on seed yield per plant was observed for head diameter. Hence, most studied traits could be employed as selection criteria for improving evaluated sunflower genotypes.

Field experiments were conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during rabi (winter) seasons of 1999-2001 to study the tillage and mulching effects on conservation of residual soil moisture, yield attributes and yield of mustard (cv. Daulat.). Three different tillage methods, namely minimum, reduced and conventional tillage were used in the main plots and three different mulch materials, namely rice straw, water hyacinth, black polythene including no mulch were used in the sup-plots. It was observed that reduced tillage and polythene mulch or rice straw mulch conserve more moisture than other tillage methods and mulch application. Tillage practice significantly influenced the dry matter, yield and yield components of mustard. Reduced tillage gave consistently the highest seed yield (969 kg/ha), while minimum tillage gave the lowest seed yield (92 kg/ha). Mulching also resulted in better crop growth and increased yield. Significantly higher seed yield (1164 kg/ha) was recorded from black polythene mulch followed by rice straw mulch (1089 kg/ha). The yield of mustard was obtained due to the interaction effects on reduced tillage and polythene mulch followed by conventional tillage and polythene mulch, which was found superior to all other treatments. Results revealed that polythene mulch or rice straw mulch accompanied by reduced tillage was economically profitable for mustard cultivation/production under rainfed condition. Key Words: Rainfed mustard, tillage, mulching. doi: 10.3329/bjar.v33i4.2303 Bangladesh J. Agril. Res. 33(4) : 597-606, December 2008

An experiment was carried-out with forty-eight hybrids of pigeonpea and two checks for nine characters at Agricultural Research Station, Tandur (Professor Jayashankar Telangana State Agricultural University). Analysis of variance revealed significant differences among the hybrids for all the nine characters studied. The results of genetic parameters revealed that, high genotypic (GCV) and phenotypic coefficients of variations (PCV) were observed for seed yield and number of pods per plant. Six characters viz., number of branches per plant, number of pods per plant, number of seeds per pod, pod length, test weight and seed yield exhibited high heritability estimates coupled with high genetic advance as per cent of mean which suggested that these traits were amenable for further improvement following simple selection methods. Character association revealed significant positive association of seed yield with plant height,number of branches per plant, number of pods per plant, number of seeds per pod and pod length. Based on divergence studies, the hybrids were grouped into nine clusters in Tocher’s method, cluster II (14 hybrids) was the largest followed by cluster I (13), cluster VI (9), cluster IV (6), cluster IX (4) and the remaining clusters were solitary (III, V, VII and VIII). Out of the nine characters studied, seed yield, days to 50% flowering, test weight and plant height contributed 85.62 per cent of the total divergence and these traits were found to be important factors for genetic differentiation in the hybrids. The overall results of the study revealed that, hybrids under cluster IV and VIII and cluster VII and VIII had maximum and minimum inter cluster distances respectively and possessing high genetic diversity for the characters viz. plant height, number of branches per plant, number of seeds per pod and yield.

Studies have shown that that about 85% of maize farmers in Western Kenya plant local varieties with about 80% using own farm-saved seeds. The production system is characterized by late harvesting, heavy striga infestation, use of local varieties, and low-soil fertility. The objective of this study was to test an on-farm seed production system which would help improve yield and quality of farm saved seeds. The trials were set up in a factorial design fitted as random complete block design. There were 3 factors each at 2 levels: time of harvest, variety choice, and fertilizer application. Fertilizer application led to an 88% increase in yield, 54% increase in number of seeds per cob, and 14% increase in 100-seed weight. Fertilizer application also led to an increase in seed vigour and viability. Yield differences between the 2 varieties were not significant. The correlation between 100-seed weight and seed vigour was significant showing that heavy seeds were more vigourous. Nitrogen application was therefore recommended for increasing yields and for producing vigourous seeds but should be done with caution to avoid lodging as witnessed. This study also noted that farmers are rational and their decisions are usually based on strong economic considerations.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

An experimental study was conducted during 2011/2012 and 2012/2013 at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Monhanpur, Nadia, West Bengal, India, to evaluate the performance of fourteen different bush type French bean genotypes for seed yield and to study varietal characterization based on plant morphology. The genotypes, studied under this experiment were namely, Abhay, Shillong Local-3, Arjun, Selection-9, Arka Anoop, Arka Komal, Badshah, Anupam, Arka Suvidha, Falguni, Sonali, Local, Victoria and Vaishnavi-264. From overall point of view of the outcome of the experiment, it has been revealed that genotype with relatively bolder seeds with more number of seeds per pod, and higher bearing capacity per plant generally gives higher seed yield. Among the genotypes under study, Arka Suvidha was the best one as it produced the highest seed yield (2180.92 kg/ha) and relatively good plant vigour and fairly high seed vigour index (2944.38). Falguni and Mohanpur Local also can be considered promising once for seed production point of view.

Gila safflower and RR 204 linseed were grown under irrigation at Kimberley Research Station in the 1964 dry season after 6-months and 18-months clean and weedy fallows. Four levels of nitrogen fertilizer, as ammonium sulphate and as urea, were superimposed. Seed yield responses to nitrogen fertilizer up to 80 lb N an acre (safflower) and 160 lb N an acre (linseed) were obtained after weedy fallows, but after 18 months clean fallow neither crop showed a significant response to nitrogen fertilizer up to 160 lb N an acre. Ammonium sulphate was more effective than urea at equivalent rates of nitrogen per acre. The amount of nitrate-nitrogen in the top three feet of soil shortly before planting was related to the total nitrogen yield of linseed at maturity, which, in turn, was closely related to seed yield. Increases in seed yield of linseed with clean fallowing and nitrogen fertilizer were largely the result of increases in bolls per plant and 100-seed weight.

Aim: To identify the best planting time for obtaining higher seed yield and quality of Soybean in off season. Study Design: Randomized completely block design (RCBD) Place and Duration of Study: Agricultural Research Station, Halladkere, Bidar, Karnataka between 2016 and 2017. Methodology: A field experiment was conducted at Agricultural Research Station, Halladkere, Bidar to find out the best off season planting time for quality seed production of Soybean. The certified seeds of soybean varieties, JS-335 and Dsb-21 were sown with recommended package of practices at appropriate field condition from November to February at every fortnight with a spacing of 30 cm X 10 cm. The quality parameters related to seed were carried out in the laboratory of seed science department. Further, soybean seeds were treated with fungicide (carbendazim 25% + mancozeb 75%) at the rate of 3 gram per kg of seeds. Results: From the present investigation, it was observed that among the different sowing dates, soybean varieties (JS 335 and DSb 21) sown during 1st fortnight of November recorded significantly higher plant growth parameters as well as seed yield followed by 2nd fortnight of November during off season. Further, climatic factors like rainfall, maximum and minimum temperature and relative humidity played a major role in the off season to produce higher seed yield and quality of Soybean. Conclusion: Among various sowing dates, November 1st Fortnight sowing resulted in highest seed yield with better seed quality in both cultivars (JS-335 and Dsb-21) of soybean.
