The experiment comprised of two factors; Factor A: Variety (3) viz. BARI mash-3 (V 1 ), BARI mash-2 (V ) and BINA mash-1(V ) and Factor B: management packages (3) viz. Low management: Fertilizer 0-0-0 NPK + 40 kg seed/ha in broadcasting + no pesticide application + no weeding (M 1 3 ), medium management: Fertilizer 20-10-20 NPK kg/ha + 24 kg seeds/ha in line sowing (30cm×continuous) + pesticide application + one hand weeding after 15 DAS (M ), high management: Fertilizer 40-20-40 NPK kg/ha + 24 kg seed/ha in line sowing + pesticide application (ripcord) + two hand weedings at 15 and 25 DAS (M 2 ). The experiment was laid out in split-plot design with three replications. Data on different growth parameters, yield attributes and yield of blackgram were significantly varied for different parameters. The highest emergence percentage (33.44%), plant height (53.54 cm), number of leaflet plant -1 ( 19.89), dry weight (8.95 g plant -1 ), branches plant (2.22), 1000-seed weight (33.74g) and seed weight (0.58 t ha -1 ) was found from BARI mash-2. The management packages resulted highest emergence percentage (41.11%), plant height (79.39 cm), leaflet plant -1 (52.13), dry weight plant -1 (8.95g), branches plant (3.00) and seed yield (0.63 t ha -1 ) from high management (M 3 ). The highest leaflet plant (56.8 cm) was revealed in V 2 M 3 , and the highest seed yield (1.06 t ha -1 ) and higher harvest index (49.75) was obtained from V 2 M . From the above results it was appeared that BARI mash2 with high management provided the best yield attributes and yield of blackgram.

HASAN The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka during the period from March to June, 2018 to study the effects of agronomic managements on growth and yield of Aus rice. The experiment comprised as two factors having two varieties in the main plots and five agronomic managements in the sub-plots under split-plot design with three replications. Significant variation was recorded for weed severity, different yield contributing characters and yield of Aus rice. The lowest weed population (26.67 m -2 ) and weed dry weight (1.96 g m -2 ) was recorded in M (recommended management) and M 2 (no fertilizer application), respectively, whereas the highest weed population (520.70 m -2 ) was found in the M (no management) but the highest dry weight (329.90 g m -2 ) in M (no weeding) treatment. At 30, 50, 70 DAS and harvest the taller plant (24.61 cm, 41.27 cm, 60.23 cm and 80.28 cm, respectively), grain yield (0.96 t ha -1 1 ) and straw yield (2.75 t ha -1 ) were recorded from V 2 compared to that of V . Similarly the tallest plant (27.11 cm, 49.66 cm, 71.49 cm and 91.07 cm at 30, 50, 70 DAS and harvest, respectively), grain yield (2.34 t ha -1 1 ) and straw yield (5.30 t ha ) were observed from M 4 . In respect of interaction, the highest grain yield (2.43 t ha ) and straw yield (5.31 t ha -1 ) were observed from V 1 M (BRRI dhan65 with recommended management), while the lowest grain yield (0.12 t ha 4 ) from V 1 M 0 (BRRI dhan65 with no management) and straw yield (0.85 t ha ) from V 2 M (Nerica with no management). Irrespective of variety, no management reduced 94-95% grain yield of Aus rice that was 84-89% for no weeding and no fertilizer application.

M. MUNIM HOSSAIN A field experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2017 to January 2018 to study the effect of growth regulators on growth and yield of mungbean under different late sowing conditions in kharif-II season. The experiment was comprised of two factors; factor A: growth regulators (6) viz. G 0 ii = distilled water, G = 20 ppm BAP (Benzylaminopurine), G 2 = 40 ppm BAP, G 3 = 20 ppm GA 3 1 (Gibberellic acid), G = 40 ppm GA 3 , G 5 = 60 ppm GA 3 and factor B: sowing date (2) viz. S 1 = sowing on 31 October, 2017, S 2 = sowing on 14 th November, 2017. The experiment was laid out in randomized complete block design (RCBD) in factorial arrangements with three replications. Results revealed that in case of growth, plant height (38.35 cm), and dry weight (9.57g) plant -1 were significantly higher in G 5 (60 ppm GA ) treatment. In terms of yield and yield attributes, number of pods plant -1 (6.56), number of seeds pod -1 (5.52), weight of 1000- seeds (35.07 g), seed yield (0.26 t ha ), and harvest index (37.75 %) were higher in G 5 (60 ppm GA 3 3 -1 ) treatment). Sowing at 31 October showed better results in case of all growth and yield parameters than sowing at 14 November. Results from Interaction effect between different levels of growth regulators and different sowing conditions revealed that the highest plant height (39.43 cm), number of pods plant -1 (8.80), number of seeds pod -1 (7.22), weight of 1000-seeds (38.74 g), seed yield (0.45 t ha -1) were observed in S 1 G October with 60 ppm Gibberellic acid) interaction. The results in this study indicated that the plants performed better in respect of growth, yield and others yield contributing characters in S 1 G 5 (Sowing on 31 th 5 October with 60 ppm Gibberellic acid) treatment.

The experiment consisted of two level of treatments viz. variety and transplanting dates. The experiment was comprised with two rice varieties viz. BRRI dhan52 and Kumragor (local T. aman rice) and seven transplanting dates viz. 1 July, 10 July, 20 July, 30 July, 10 August, 20 August, 30 August. The experiment was laid out in Randomized Complete Block Design (RCBD) with five dispersed replications. Results indicate that variety and date of transplanting exerted significant influence on the crop characters of aman rice. BRRI dhan52 produced the highest grain yield (3.51 t ha ), straw yield (3.72 t ha -1 ), biological yield (7.24 t ha ii -1 ), and harvest index (48.30%). The lowest grain yield (2.71 t ha -1 ), straw yield (4.40 t ha -1 ) and biological yield (6.57 t ha -1 ) and harvest index (32.88%) were obtained from Kumragor. Kumragor took longest duration 152 days to mature while BRRI dhan52 took 133 days to mature. Plant height (140.12 cm), number of total tillers m- 2 (240), number of grains panicle -1 (132.19), grain yield (3.63 t ha -1 ), straw yield (4.60 t ha -1 ), biological yield (8.27 t ha -1 ) and harvest index (44.01%) were highest with 10 August transplanting and decreased gradually after mid-August transplanting but drastically declined with 30 August transplanting. Drastic decrease of yield was showed on both of the transplanting date 1 July and 30 August. The present study indicates early August to be the most suitable transplanting date for aman rice in polder ecosystem of coastal zone.
