The experiment was consisted of two types of plant growth regulators, viz. i) Auxin (IAA- Indole acidic acid) and ii) Gibberellic acid (GA 3 ). Nine levels of foliar spray with IAA and GA 3 application viz. i) Control (T 0 ), ii) Spraying IAA @ 25 mg/L at 30 DAS (T 1 ), iii) Spraying IAA @ 50 mg/L at 30 DAS (T 2 ii ), iv) Spraying GA 3 @ 25 mg/L at 30 DAS (T 3 ), v) Spraying GA 3 @ 50 mg/L at 30 DAS (T 4 ), vi) Spraying IAA @ 25 mg/L + GA 3 @ 25 mg/L at 30 DAS (T 5 ), vii) Spraying IAA @ 25 mg/L + GA 3 @ 50 mg/L at 30 DAS (T 6 ), viii) Spraying IAA @ 50 mg/L + GA 3 @ 25 mg/L at 30 DAS (T 7 ) and ix) Spraying IAA @ 50 mg/L + GA 3 @ 50 mg/L at 30 DAS (T 8 ). The experiment was laid out in randomized complete block design (RCBD) with three replications. The data regarding on plant height, number of leaves, number of branches were recorded both 30 days after sowing (DAS) and at harvest. The other parameters were recorded meanwhile cultivation and at the time of harvest. Results revealed that in case of morphological parameters, plant height (57.50 cm), number of leaves (17.33) plant and number of brunch (7.67) plant -1 were significantly higher in T 8 (IAA @ 50 mg/L + GA 3 @ 50 mg/L) treatment. In terms of growth characters; SPAD value (55%), days to flowering (27.33) and days to maturity (55.33) were also significantly higher in T 8 (IAA @ 50 mg/L + GA 3 @ 50 mg/L) treatment. The data regarding yield and yield attributes, number of pods plant -1 (37.66), pod length (14.99), number of seeds pod (13.78), weight of 1000- seeds (54.95g), seed yield (1.62 t ha -1 ), stover yield (1.78 t/ha), biological yield (3.74t/ha), and harvest index (37.75 %) were higher in T 8 (IAA @ 50 mg/L + GA 3 @ 50 mg/L) treatment. However, (T 0 ) untreated control (IAA 0.0 mg/L, GA 3 0.0 mg/L) showed the lowest performance in every stages. The result indicated that the plants treated with T 8 (IAA @ 50 mg/L + GA 3 @ 50 mg/L), performed better in respect of growth, yield and others yield contributing characters.

RAKIB The field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from November, 2019 to May, 2020 in Boro season to find out the effect of variety and zinc application on the performance of hybrid rice. The experiment consisted of two factors as Variety (3 types) viz., V 1 – BRRI hybrid dhan2, V – BRRI hybrid dhan3 and V 3 – BRRI hybrid dhan5 and Zinc management (4 levels) viz., Zn ii 2 (control), Zn 1 – 2 kg ha -1 , Zn 2 – 4 kg ha -1 and Zn 3 – 6 kg ha -1 . The experiment was laid out in a Randomized Complete Block Design (Factorial) with three of replications. Data on different growth and yield parameter of rice were recorded and significant variation was found for different treatments. Regarding varietal performance, the maximum panicle number hill -1 (17.10), panicle length (28.03 cm), grain number panicle -1 (109.45), 1000-grain weight (26.50 g), grain yield ha (6.94 t), straw yield ha -1 (8.58 t), biological yield ha -1 (15.51 t) and harvest index (44.62%) were found from the variety V . Considering Zn effect, the maximum panicle number hill -1 3 (16.33), panicle length (27.14 cm), grain number panicle -1 (108.11), 1000-grain weight (25.38 g), grain yield ha 1 -1 (6.81 t), straw yield ha (15.15 t) and harvest index (44.88%) were found from Zn -1 0 - 0 kg ha -1 (8.34 t), biological yield ha 3 (6 kg Zn ha ). In case of treatment combination of variety and zinc, the maximum panicle number hill (20.17), panicle length (29.17 cm), number of grains panicle -1 (179.74), 1000-seed weight (27.43 g), grain yield (7.76 t ha -1 ), straw yield (9.19 t ha -1 ), biological yield (16.95 t ha -1 ) and harvest index (45.78%) were found from V 3 Zn . The hybrid rice variety ‘BRRI hybrid dhan5’ with a Zn application of 6 kg ha -1 3 yielded considerably more grain than the other treatment combinations under evaluation.

The experiment consisted of three rice varieties viz., V 1 (BRRI dhan88), V 2 (BRRI dhan89) and V (BRRI dhan100) in combination with four sulphur treatments viz., S 0 (control; 0 kg S ha 3 -1 ), S ), S 2 (40 kg S ha -1 ) and S 3 (50 kg S ha -1 ). The experiment was laid out in Randomized complete Block Design (RCBD) with three replications. Among different rice varieties, V (BRRI dhan100) showed better performance on different growth parameters, but considering yield and yield contributing characters V 3 (BRRI dhan89) exhibited better performance,whereas V 1 2 (BRRI dhan88) gave the least performance. Among sulphur treatments, S 2 (40 kg S ha -1 ) gave the best results considering other treatments followed by S 3 (50 kg S ha -1 ) whereas control treatment S 0 (0 kg S ha -1 ) showed the lowest performance. In terms of combined effect of variety and sulphur treatment, V showed better results regarding yield contributing and yield characters and gave the highest number of effective tillers hill -1 (21.67), panicle length (29.87 cm), number of filled grains panicle -1 (114.80), 1000 grain weight (24.30 g), grain yield (8.57 t ha ), straw yield (9.59 t ha -1 ) and harvest index (47.16%), whereas the lowest results were recorded from V 1 S 0 . Therefore, among the treatment combinations, V 2 S (BRRI dhan89 with 40 kg S ha -1 2 ) can be considered as the best treatment combinations followed by V (BRRI dhan89 with 50 kg S ha -1 ) compared to other treatment combinations.

KHATUN, RESHMA Sowing time is an important agronomic factors that significantly affects plant growth development and final production. Similarly, suitable cultivar also plays an appreciable rate in final productivity. Therefore, the experiment was conducted in the research field of the Sher-e-Bangla Agricultural University, Dhaka from March 2020 to June 2020 to study the effect of sowing date on growth and yield of Mung bean (Vigna radiata L). This experiment consisted of three Mung bean varieties viz. V 1 = BARI Mung-5, V 2 = BARI Mung-6, V 3 = BARI Mung-7 sown on three different dates termed as treatments i. e. T 1 = 15 March 2020, T 2 = 30 March 2020, and T 3 = 15 April 2020 and different parameters were recorded. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The experimental plot was fertilized at the rate of 40 kg/ha (Urea), 80 kg/ha (TSP), 30 kg/ha (MoP) and necessary intercultural operations were done. The data regarding plant height, number of leaves and number of branches were recorded at both 30 Days after sowing (DAS) and harvest, and the other parameters were recorded at the time of harvest only. At 30 DAS, the highest plant height (22.67 cm) was observed in V 2 when sown on T 1 and during harvest plant height was found highest (55.17 cm) in the same variety with the same treatment. At 30 DAS and harvest, the highest number of leaves (average 4.33 and 15 respectively) were obtained in V 2 when sown on T 1 . In case of number of branches, at 30 DAS and harvest, the highest number (average 2.67 and 7.67) were observed in V 2 when sown on T 1 and T 3 respectively. The variety V 3 takes longer time for maturity (66 days) and V 1 variety takes less time for maturity (55.67 days). In terms of yield and yield attributes, the highest number of pods per plant (39) were recorded in V 2 when sown onT 1 and the number of fertile seeds per pod were recorded highest (14) in V 2 when sown onT 1 . The maximum pod length (14.67 cm) was recorded in V 2 when sown on T 1 . In case of 1000- seed weight the highest value (53.18 g) was recorded in V 2 when sown on T 1 . The maximum SPAD value (55), the highest yield (1.68 t ha -1 ), maximum biological yield (3.5 t ha ), the highest Stover yield (1.88 t ha -1 ) was recorded in V 2 when sown on T 1 . Finally, the maximum Harvest Index (53.33 %) was calculated in V 2 when sown on T 1 . The results in this study indicated that the variety performed better in respect of growth, yield and others yield contributing characters’ is V 2 (BARI Mung -6) on the sowing time T 1 (15 March 2020).
