Study was conducted in 2006 and 2007 cropping seasons at the experimental field of Federal University of Technology, Minna (9o 401N and 6o 301E), in the Southern Guinea Savanna of Nigeria to determine the effects of N fertilizer and the fruit positions on fruit and seed yield of okro. The treatment comprised factorial combination of five nitrogen levels (0, 30, 60, 90 and 120 kg/ha) and five fruit positions on a mother-plant (3, 5, 7, 9 and 10) which were replicated three times and laid in a Randomized Complete Block Design (RCBD). The results indicated that significant taller plants were recorded in the plots that received 120 kg N/ha while shorter plants were recorded in plots that received 0 N/ha in both years of the study. The higher N level of 120 kg/ha and lower fruit position of 3 significantly gave higher number of fruit yield while the yield decreased with decrease in N level and increase in fruit position on the mother-plant. Similarly, heavier fruits were recorded in lower fruit positions and higher N levels. The fruits formed at the lower position 3 and 5 produced more seeds with higher seed weight than those formed at the higher positions. The results also showed that significantly higher seed yield was recorded at N level of 120 kg/ha ?.

An investigation was carried out at the experimental field of the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during September to November 2014 to evaluate the productivity of three mungbean genotypes, viz., GK-24 (G1), GK-63 (G2) and BU mug 4 (G3) under four plant spacing (densities) such as i) 15 cm x 10 cm= 66 plants m-2 (D1), ii) 20 cm x 10 cm= 50 plants m-2 (D2), iii) 25 cm x 10 cm= 40 plants m-2 (D3) and iv) 30 cm x 10 cm=33 plants m-2 (D4). The experiment was conducted in a factorial randomized complete block design with three replications. A wide variation among the genotypes was observed in relation to light transmission, yield, and yield contributing characters. At 30 cm x 10 cm spacing (D4) the highest light transmission ratio (LTR) was observed in G1 genotype (57.92) and the lowest LTR value in G2 genotype (46.92). Among the three genotypes, G1 produced the highest seed yield (1094 kg ha-1). But highest seed number pod-1 was found in D2 (11.61) while maximum pods plant-1 (11.08) was in D4 treatment followed by D3 (10.59). Among the four plant densities, treatment D3 showed the highest 1000-seed weight (50.30 g). The highest seed yield (1114 kg ha-1) was recorded in the treatment D4. Among the interaction, the highest number of seeds pod-1 (12.20) was found in the treatment D1G3, though the highest number of pods plant-1(12.03) was in treatment D4G1 but the1000-seed weight was the highest (51.92 g) in D3G1. The highest seed yield (1230 kg ha-1) was recorded from treatment D4G1. The result showed that GK 24 genotype performed the best in all respects of yield and yield attributes at 30 cm x 10 cm spacing compared to other treatments.Bangladesh Agron. J. 2016, 19(1): 11-17

Source-sink manipulation may improve light interception into the canopy and reduce the competition between vegetative and reproductive sinks during seed filling period, and may help in achieving higher yield. So, an effort was made to assess the effect of source-sink manipulation on yield contributing characters and yield of sesame. The experiment was laid out in two factors randomized complete block design consisted of two varieties of sesame viz.Binatil-3 and Local-Black and five levels of source-sink manipulation viz.control (M0), removal of lower empty leaves, lower empty branches and top of the inflorescence (M1), removal of top of the inflorescence (M2), removal of all branches and removal of lower empty leaves (M3) and lower empty branches (M4) with three replications. Source-sink manipulations were imposed during capsule development stage (50 days after emergence). Results revealed that the higher number of capsules plant-1 (16.17), seeds capsule-1 (53.27), maximum 1000-seed weight (2.72 g), higher seed capsule wall ratio (2.52), seed yield plant-1 (2.35 g), yield (938.96 kg ha-1) and harvest index (36.40%) were produced by the modern variety Binatil-3 than the traditional variety Local-black. Source-sink manipulation showed positive response to yield attributes compared with control. Maximum seeds capsule-1 (57.13), 1000-seed weight (2.92 g), higher seed capsule wall ratio (2.71), seed yield plant-1 (2.78 g) and yield (1110.96 kg ha-1) were found from removal of lower empty leaves, lower empty branches and top of the inflorescence (M1). Yield was increased by 71.77%, 46.88%, 8.52% and 22.45% due to M1, M2, M3 andM4 manipulation. Although all the source-sink manipulation treatments gave higher yield in their respective variety, the highest (1258.63 kg ha-1 and 125.04%) yield was obtained when lower leaves, lower empty branches and top of the inflorescence of the variety Binatil-3 were removed i.e. from V1M1 treatment. Therefore, Binatil-3 with removal of lower empty leaves, lower empty branches and top of the inflorescence manipulation was the best treatment in respect of yield and yield contributing characters of sesame.Progressive Agriculture 29 (1): 1-9, 2018

A varietal trial of mustard was conducted at Noagaon village of Dekhar haor areas of south Sunamganj upazila of Sunamganj district, during November 2015 to March 2016, to find out the suitable mustard variety/varieties. A total of five varieties viz. BADC 1, SAU Sarisha-3, BARI Sarisha-11, BARI Sarisha-14 and BARI Sarisha-15 were tested in the farmer’s field. The experiment was carried out in a randomized complete block design with three replications. Significant differences were found among the mustard varieties for number of branches plant-1, number of capsules plant-1, capsule length, 1000-seed weight and seed yield. The mustard var. BARI Sarisha-11 produced the highest number of branches plant-1, number of capsules plant-1, 1000-seed weight resulting the highest seed yield (1.64 t ha-1), followed by BARI Sarisha-15 (1.47 t ha-1). The seed yield of BARI Sarisha-11 and BARI Sarisha-15 was not differed significantly, but the growth duration of BARI Sarisha-15 was shorter than the others.Bangladesh Agron. J. 2017, 20(1): 1-5

Feld experiments were conducted at four locations of Bangladesh (Manikgonj, Cumilla, Dinajpur and Joshore) to optimize sowing date for higher seed yield of jute in late sown condition. The experimental variables constituted with three genotypes (O-72, O-3820 and Acc.4311) and three sowing dates (31 July, 15 August and 30 August).Each experiment was laid out in a randomized complete block design with three replications. The treatment combinations were assigned randomly and afresh randomization was followed in each replication. Results showed that the genotype Acc.4311, O-72 and O- 3820 produced maximum number of branches (5.40, 4.90 and 4.40, respectively) plant-1 on 15 August sowing at Manikgonj. The genotype Acc.4311 produced higher number of pods plant-1 than other two genotypes (O-72 and O-3820) in all sowing dates andat all the locations. The highest number of seedspod-1 (220.80) was found from the genotype Acc.4311grown at Manikgonj which was statistically similar (196.90) with that of the same genotype sown on the same date at Joshore. The highest thousand seed weight (2.478 g) was recorded from the seeds of genotype Acc.4311 sown on 15 August at Manikgonj followed by same genotype at Joshore.Finally, the genotype Acc.4311 sown on 15 August produced the highest seed yield (2.478 t ha-1) at Manikgonjwhich was significantly higher than those of sown on 31 July and 30 August at the same location. As the genotype Acc.4311 was found outstanding sown on 15 August over locations, this genotype may be considered promising for higher seed yield of olitorius jute in late season. Bangladesh Agron.

The experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November 2016 to February 2017. The experiment has consisted of three different ways of insect visitors foraging for pollination of mustard flowers viz., T1= Open field (Control), i.e., the mustard field was fully open for free movement by the insect pollinators, T2= Netting with honey bee, i.e., the mustard plots was caged with muslin net and the bee hive was placed inside the cage and T3= Netting without honey bee, i.e., the mustard plots was caged with muslin net but the bee hive was not placed inside the cage. BARI Sharisha-8 [Brassica juncea (L.) Czernajew] was used as planting material. Randomized Complete Block Design was selected to lay out the present experiment with 7 replicates. Study showed that, honey bee was the most abundant hymenopterans in the mustard field as a pollinator. The yield and yield contributing traits were significantly influenced by different ways of insect visitors foraging for pollination. The maximum (3.50 g) 1000-seed weight was recorded from treatment T2 followed by T3 and the lowest 1000- seed weight (2.68 g) was recorded from T3. The highest seed yield (2.45 t ha-1) was exhibited from treatment T2 followed by T1 whereas the lowest seed yield (1.67 t ha-1) was recorded from T3. Finally, it can be concluded that, providing honey bee colonies to the flowering mustard field can substantially contribute to the yield.

A field experiment was carried out in the rainy season of 2019 in Gombe states, Nigeria. The experiment was carried out in Tal, Billiri Local Government, Gombe State. The aim of the experiment was investigate the performance of ten varieties of sesame. The ten different varieties were; E-8, NCRIBEN-01, NCRIBEN-02, NCRIBEM-031, YANDEV-55, EX-BR-1, EX-BR-2, E-SUDAN, 560-1 and LOCAL. The treatments were laid in a randomized complete block design with three replications. The treatments were combined to have 10 plots in a block with 1 meter between the block and 0.5 meters within the plots. The seeds were placed in 5cm depth at the spacing of 15 x 75cm. During the research growth parameters like plant height, number of leaves and number of branches were measured. Other growth parameters like days of 1st flower, 50% flower, days of maturity, number of capsule per plant, seeds per capsule, number of capsule per leaves axis, 1000 seed weight and seed yield were also recorded. The results of the experiment revealed that sesame generally responded to both varietal and fertilizer effects. All the parameters studied have significantly (P≤0.05) responded to the varietal effects, here variety NCRIBEN-01 and E-8 were observed to perform higher in both growth parameters, yield related character and overall yield. Based on the result obtained it can be suggested that the use of E-8, NCRIBEN-01, NCRIBEN-02, NCRIBEN-031, YANDEV-55 will give high yield followed by EX-BR-1, EX-BR-2, E-SUDAN and 506-1 leading to optimum yield for farmers in Tal, Billiri Local

In addition to the good adaptation of high temperatures and poor soils, cowpea (Vigna unguiculata L.) can be a good source of forage for livestock. This study was carried out to determine seed yield and some agronomical parameters of cowpea grown in different row spaces as double crop in Samsun ecological conditions. In the experiment, forage cowpea cultivar Ulkem and Line H-8 grown in four row spaces (20, 35, 50, 65 cm) in a Randomized Split Block Design with three replications. Seeds were sowed after harvesting wheat at July 13, 2017 and 15 July 2018. Seed harvest was made at October 20, 2017 and November 5, 2018. The results showed that seed yields ranged from 765 to 2178 kg ha-1 in 2017 and 397 to 1464 kg ha-1 in 2018. 1000 seed weight ranged from 161.17 to 183.93 g in 2017 and 146.40 to 160.90 g in 2018. In 2017 and 2018, mature pod ratio were 65.7 – 85.8, 30.0 – 60.3% respectively. Pod number per plant was between 5.66-15.00 pods/plant in 2017, 9.50-16.25 pods/plant in 2018. Seed number per pod was ranged from 8.80 to 12.43 seeds/pod in 2017, from 8.00 to 11.50 seeds/pod in 2018. Though the highest seed yields were obtained from 20 cm row space, it is risky cultivated cowpea for seed production as double crop in Samsun conditions because of earlier autumn rainfall and high humidity.

An experiment was conducted to evaluate eighteen Brassica genotypes for various morphological characters and estimate association for yield and yield contributing traits. The experimented was executed following Randomized complete block design (RCBD) with three replications in the experimental farm of the department of Genetics and Plant Breeding, Bangladesh Agricultural University Mymensingh-2202. The nine yield attributing characters are studied in the experiment. The genotypes differed significantly for all the traits viz., days to 1st flowering, days to maturity, plant height, number of branches/plant, number of pod/plant, length of pod, number of seeds/pod, 1000-seed weight (g) and seed yield/plant (g).Considering the two most important traits like early maturity and yield /plant, BD-7114 performed best among the studied genotypes. Correlation coefficients among the characters were studied to determine the association between yield and it attributing components. A significant positive correlation was found between yield and its attributing characters namely with number of seeds/pod and 1000-seed weight. Path analysis revealed both direct and indirect effects on seed yield and revealed that number of seeds/pod had the highest direct effect on seed yield. The findings of the research could be exploited in future breeding programs for improving Brassica genotypes. Progressive Agriculture 30 (1): 39-47, 2019

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.
