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.

The growth and yield characters of chickpea varieties suitable for mechanical harvesting were evaluated through field experiment conducted for three consecutive years (2016__17 to 2018__19) during rabi season on vertisols under rainfed conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. The investigation was carried out in split plot design with three replications. Two plant geometries (30.0 × 10.0 cm and 22.5 × 10.0 cm) were assigned to main plots and six chickpea varieties (viz., GBM 2, Dheera, CSJ 515, HC 5, Phule G 08108 and BRC 1) were assigned to sub plots. Pooled analysis of experimental results indicated that significantly higher number of branches per plant (8.7) and number of pods per plant (31.1) and test weight (24.3 g) were observed under 30.0 × 10.0 cm when compared to 22.5 × 10.0 cm. Higher plant height (44.8 cm), height of lowest pod bearing branch (30.0 cm), lower days to 50 % flowering (42.1 days) and higher test weight (31.2 g) were observed in Dheera. Higher number of branches per plant (9.2) and number of pods per plant (34.2) were observed in GBM 2. Higher seed yield was observed in Phule G 08108 (1708 kg ha-1) which is followed by GBM 2 (1675 kg ha-1) Dheera (1569 kg ha-1) and BRC 1 (1493 kg ha-1). Higher harvest index (56.4%) was also observed in Phule G 08108. Chickpea varieties GBM2, Dheera and BRC1 were best suitable for mechanical harvesting and higher seed yield due to their excellent morphology.

This research was carried out in the Experimental Field of Tekirda đ Agricultural Faculty. Two common vetch varieties and 5 lines were sown with 150 seeds/m 2 plant density according to a randomised block design. Some important yield related characters such as plant height, number of branches, number of pods per plant, number of seeds per pod, pod width, pod length, 1000 seed weight, fodder and seed yield were examined. The results of variance analysis showed that the effects of genotype, year and their interaction on number of branches and number of pods per plant were all significant. In addition, the effect of year and variety on plant height and seed yield were found to be significant. Moreover, the number of seeds per pod, pod width and pod length were found to be significant in variety and year × variety interaction. There was only a difference between years for 1000 seed weight and fodder yield. According to the results, genotype 283 and Tokat had similar performance to that of commercial cultivars (Ürem, Kubilay). Especially the fodder and seed yield of genotype 283 were found to be higher than those of the cultivars (Ürem, Kubilay).

The experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna during rabi season of 2011-2012 and 2012-2013 to find out the appropriate sowing date and optimum plant spacing for seed production of cauliflower (var. BARI Phulcopi-1). Four sowing dates viz. 20 September, 1 October, 10 October and 20 October and three plant spacing viz. 60 cm × 50 cm, 60 cm × 60 cm and 60 cm × 70 cm were used as treatment variables. Significant variation in seed yield and yield contributing characters of cauliflower were observed due to execution of different sowing dates and plant spacing. Number of branches plant-1, number of pods plant-1 and number of seeds pod-1 showed the highest in 1 October sowing as a result the highest seed yield (361.69 kgha-1) was obtained from same date of sowing. Sowing on 10 October and 20 October reduced seed yield drastically compared to that obtained from 1 October sowing. The lowest seed yield (188.54 kgha-1) was obtained from 20 October sowing. On the contrary, closer spacing (60 cm × 50 cm) produced the highest seed yield (315.88 kgha-1) and the wider spacing (60 cm × 70 cm) produced the lowest seed yield (254.07 kgha-1). However, combination of 1 October sowing with 60 cm × 50 cm plant spacing produced the highest seed yield (414.81 kgha-1) due to higher number of seeds pod-1. The seed yield decreased after 10 October sowing irrespective of plant spacing. So, early sowing (1 October) with closer spacing (60 cm× 50 cm) would be economically profitable for cauliflower seed production in North-Western part of Bangladesh.Bangladesh J. Agril.

Six concentrations each of KNap and NAA along with a control were tested on cowpea cv. Bari Falon- 2. Results showed that irrespective of treatment differences, dry matter of cowpea (Vigna unguiculata) increased during 60 to 105 DAS. Concentrations above 50 ppm NAA increased plant height. The dry matter and yield increased with the increasing of the concentrations of KNap and NAA up to 1250 and 50 ppm, respectively. No significant differences of dry matter accumulation, grain yield and almost all the yield attributes were observed in between 1250 ppm KNap and 50 ppm NAA. The highest values of dry matter/plant (54.52 g), pod length (13.15 cm), number of pods/plant (10.29), number of seeds/pod (10.61), 1000 seed weight (122 g), seed yield/plant (15.51 g), seed yield/ha (1630 kg) and harvest index (37.32 %) were obtained due to application of 1250 ppm KNap. Yield attributes had significantly positive correlation amongst them.   Key words: Cowpea, Vigna unguiculata, Plant height, Dry matter, Yield DOI = 10.3329/bjb.v36i2.1500 Bangladesh J.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University to observe the effect of sowing methods and weeding regimes on the yield of sesame. The experiment comprised of two factors. Two methods of sowing i.e., broadcasting and line sowing (S2), and six weeding regimes- control (T0), weed free (T1), one hand weeding at 15 DAS (T2), two hand weedings at 15 and 30 DAS (T3), three hand weedings at 15, 30 and 45 DAS (T4) and application of Panida (Pendimethalin) herbicide (T5) at 3 DAS. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Almost all the yield characters of sesame were affected significantly due to sowing methods, weeding regime and their interaction. Result showed that the l ine sowing showed better performance regarding plant height (100.40 cm), number of branches (4.983) plant–1, number of capsules plant–1 (47.82), number of seeds capsule–1 (69.66), 1000–seed weight (2.96 g), seed yield (956.90 kg ha–1), stover yield (2167.0 kg ha–1), biological yield (3123.00 kg ha–1) and harvest index (31.45%) than that of broadcasting method. Also weed free treatment had the highest plant height (101.90 cm), highest number of branches (5.00) plant-1, highest capsule (47.08) plant–1, heaviest 1000–seed weight (3.28 g), highest number of seeds capsule–1 (76.22), highest seed yield (974.30 kg ha–1), stover yield (2947.0 kg ha–1) and biological yield (3922.0 kg ha–1) as compared to other treatments while unweeded plot had least significant effect among the whole yield and yield attributes of sesame. In case of interactions, both weed free treatment and herbicidal effect with line sowing methods produced the highest plant height, number of branches and capsules plant–1, seeds capsule–1, seed yield, stover yield and biological yield (109.80 cm, 5.967, 56.57, 81.53, 1054.0 kg ha–1, 3139.0 kg ha–1 and 4193.0 kg ha–1, respectively) as compared to other interaction combinations. The results of the study reveal that the weed free treatment along with line sowing would be the proper technique for higher production of sesame. But line sowing along with application of Panida herbicide would be the best combination for obtaining higher yield of sesame since it is not feasible for the farmers to keep their field weed free throughout all the growing periods.

The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3 populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3 population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher concentrations of these mutagens inhibited them to different extent.

Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66),  number of pods plant-1 (41.56), number of seeds pod-1 (58.83),  seed yield    (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87),  number of pods plant–1 (46.13),  number of seeds pod-1 (56.67),  seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.

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.

A field experiment was conducted at Regional Research Station (Punjab Agricultural University) Gurdaspur and Krishi Vigyan Kendra, Pathankot during the spring season of 2016, to determine the performance of kidney bean genotypes at different sowing dates under sub-mountainous conditions of Punjab. The two kidney bean genotypes i.e. red and speckled were evaluated for yield potential at two locations by adopting different sowing dates viz., 20th January, 1st February, 10th February and 20th February, 2016. The treatments were laid out in split plot design with four replications by keeping sowing dates in main plots and genotypes in sub plots. Among different dates of sowing, crop sown on 10th February showed superiority than other dates through higher emergence count per meter row length, plant height, branches per plant, pods per plant, seeds per pod, length of pod, biological yield and seed yield. The seed yield in February 10 sown crop was 66.4, 33.3 and 21.7 per cent higher than February 20, January 10 and February 1 sown crop, respectively at Gurdaspur. Similarly, at Pathankot, the percent increase in seed yield in February 10 sown crop was 36.0 and 7.2 per cent as compared to February 20 and February 1 sown crop, respectively. The kidney bean genotype speckled produced significantly higher yield attributes (seeds per pod, length of pod and 100 seed weight) and seed yield at both Gurdaspur and Pathankot (935.1 and 823.1 kg per ha, respectively) as compared to red genotype. Therefore, it can be concluded that to attain higher productivity of kidney beans, the speckled genotype could be used for cultivation by adopting February 10 as the optimum time of sowing in the sub-mountainous area of Punjab.

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
