Ten rice genotypes viz. L1= BRRI dhan29× BRRI dhan36, S 2 P 2 P 4 S 6 , L2= BRRI dhan29× BRRI dhan36, S 5 P 2 P 4 S 6 , L3= BRRI dhan28×BRRI dhan29, S 2 , L4= BRRI dhan28×BRRI dhan29, S 2 P 4 P 3 S 2 , L5= BRRI dhan29×BRRI dhan36, S 5 P 2 P 4 S 5 , L6=BRRI dhan26×BRRI dhan28, S 1 P 9 P 4 S 1 , L7= BR 21×BRRI dhan29, S 2 P 1 S 1 , L8= BR 21×BRRI dhan29, S 6 P 1 P 1 S 2 , L9=BR 21×BRRI dhan29, S 6 P 1 P 1 S 1 , L10= BR 24×BRRI dhan36, S 8 P 1 P 1 S 1 were used for this present study. The experiments were designed in a randomized complete block design (RCBD) with three replications. All data were analyzed by one-way analysis of variance (ANOVA) using MSTATC. Differences were found in the genotypes studied characteristics viz. penultimate leaf pubescence, penultimate leaf: shape of the ligule, flag leaf: attitude of the blade, time of heading (50% of plants with heads), time of maturity, grain length, decorticated grain length and polished grain: size of white core or chalkiness (% of kernel area) and rest of the characters found no variation. Seven lines (L3, L4, L5, L6, L7, L8, L10) showed long grain length and rest three lines (L1, L2, L9) showed very long category of grain length. Medium type of decorticated grain length were found in six lines (L3, L4, L6, L7, L8, L10) and rest four lines (L1, L2, L5, L9) found long type of grain length after dehulling. Six lines (L3, L4, L6, L7, L8, L10) were represented small and four lines (L1, L2, L5, L9) were showed medium size of white core of polished grain. The maximum number of ineffective tillers per plant (15.80) was recorded from L2 and the minimum number of ineffective tillers per plant (0.37) was recorded from L7. The highest panicle length (24.90 cm) was recorded from L7 and the lowest panicle length (22.17 cm) was recorded from L2. The highest number of filled spikelets per panicle (119.90) was recorded from L7 while the highest number of unfilled spikelets per panicle was recorded in L2 (88.93). The highest grain yield (3.83and 5.25 t ha -1 ) was recorded from L7 and the lowest grain yield (1.19 and 3.23 t ha -1 ) was observed in L2. The highest harvest index (43.10 %) was recorded from L7. Line L7 (BR 21× BRRI dhan29, S 2 P 1 S 1 )was better cultivar in terms of quality, yield and yield contributing characters.

SHAKHAOWAT The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from March 2019 to June 2019 to observe the effect of bio-fertilizer on yield and seed quality of blackgram with combination of nitrogen and phosphorus. The experiment consisted of two factors viz. Factor A: two bio-fertilizer levels; (i) B = Without bio-fertilizer (control) and (ii) B 1 ii 0 = With bio-fertilizer and Factor B: Five N+P levels; F = Control (without N+P fertilizer), F = 40% lower than recommended doses of N+P fertilizer, F 2 1 = 20% lower than recommended doses of N+P fertilizer, F = recommended doses of N+P fertilizer, F 4 = 20% higher than recommended doses of N+P fertilizer and F 5 = 40% higher than recommended doses of N+P fertilizer. The experiment was conducted in split-plot design with three replications. A significant variation among the treatments was found while biofertilizer application and different levels of N+P fertilizers applied in different combinations. The maximum number of pods plant -1 (38.52), pod length (4.22 cm), number of seeds pod -1 (6.50), 1000-seed weight (44.05 g), seed yield (1.76 t ha -1 ), stover yield (3.40 t ha -1 ) and biological yield (5.16 t ha -1 ) were obtained from the treatment combination of B 1 F but the highest harvest index (34.28%) was obtained from the treatment combination of B 3 1 F whereas the lowest was from the treatment combination of B 0 F 0 2 . Considering seed quality parameters, all the parameters were significantly affected by combined effect of biofertilizer and N+P treatments. The highest percent germination (94.70%) and shoot length (25.40 cm) were obtained from the treatment combination of B but the highest root length (10.86 cm) and dry weight plant -1 (0.15 g) and also lowest electrical conductivity (7.83) were obtained from the treatment combination of B 1 F compared to all other treatment combinations. As a result, it can be accomplished that application of bio-fertilizer and N+P treatment combination B 1 F 3 4 is very much effective for higher yield and better seed quality of blackgram.

FOYSAL A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from September, 2018 to March, 2019 to find out the influence of vermicompost and plant density on growth and quality seed yield of coriander. The variety BARI Dhonia 1 was used in the experiment as the test crop. The experiment consisted of two factors: Factor A: three different plant densities viz. P 1 = 20 plants/m 2 , P 2 = 40 plants/m 2 , P 3 = 80 plants/m and Factor B: four levels of vermicompost viz. V 0 = 0 t/ha, V 1 = 5 t/ha, V 2 2 = 10 t/ha and V = 15 t/ha. There were 12 treatment combinations and experiment was setup in Randomized Complete Block Design (RCBD) with three replications. The result indicated significant variations in plant height, number of primary branches per plant, number of umbels per plant, umbellate per umbel, number of seeds per plant, dry seed weight per plant, dry seed weight per plot, seed yield, germination percentage, electric conductivity test value, seedling root length and shoot length due to different plant density and/or vermicompost application. Results also revealed that, 40 plant/m ) treatment significantly influenced the morphological characters, yield contributing characters and seed quality of coriander. The highest germination percentage (77.33 %) was also obtained from this treatment but 80 plant/m 2 (P ) treatment significantly influenced on yield which gives highest seed yield (2.66 t ha 3 -1 ) due to its high plant density. Results also revealed that, application of 15 t ha -1 3 vermicompost (V ) treatment significantly influenced the morphological characters, yield contributing characters, yield and seed quality of coriander. The highest seed yield (2.71 t ha ) and germination percentage (78.66 %) was also obtained from this treatment. Among the treatment combination, P 3 V 3 (80 plant/m 2 with 15 t/ha vermicompost) treatment seemed to be more promising for obtaining higher yield (3.33 t ha -1 ) but application of 15 t ha -1 of vermicompost with 40 plants m -2 (P 2 V ) combination seemed to be more suitable for getting quality seed production of coriander. .

MEHEDI An experiment was conducted at the central farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2018 to April 2019 to determine the growth, seed yield and quality of chilli as influenced by fertilizer management and spacing. The experiment consisted of two factors Factor A: Different fertilizer management such as F : Vermicompost (15 t ha -1 ), F 2 : 110 kg ha -1 N, 170 kg ha -1 0 , 100 kg ha : ½ Vermicompost + ½ N 110 P 170 K 100 kg ha -1 ; Factor B: Different types of plant spacing such as S 1 : 60 cm × 30 cm, S 2 : 60 cm × 45 cm and S : 60 cm × 60 cm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield contributing characters were recorded. Results indicated that fertilizer management and spacing had a significant influence on most of the growth, seed yield and quality components of chilli. Under this investigation, it was revealed that plant height, number of branches per plant, number of leaves per plant, fruit length, the weight of dry fruits, number of dry fruits per plant, yield per plant dry fruits, number of seeds per fruit, thousand seed weight, germination percentage, root length, shoot length and seedling length were found to be maximum from F 3 S 3 treatment combination and minimum from F 0 S 1 3 : Control, F -1 K and F treatment combination Yield of dry fruits (3.06 t) and seed (353.35 kg) per hectare were found to be maximum from F 3 S 2. By contrast minimum dry fruits (0.92 t) and seed yield (143.68 kg) were given from F 0 S 3 and F 0 S Considering the yield of dry fruits and seed per hectare, F3 (½ Vermicompost + ½ N 1. 110 P 170 K ) along with S 2 100 (60 cm × 45 cm) could be the best production package for the production of chilli.
