EFFECTS OF SALICYLIC ACID ON GROWTH, YIELD AND NUTRIENTS CONTENT OF OKRA DIFFERENT LEVELS OF SALINITY DHALI, DHEEMAN CHANDRA A pot experiment was conducted at the net house of Agro-Environmental Chemistry Laboratory of the Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University, Dhaka-1207, during the period from March 2019 - October 2019 to find out the effects of salicylic acid on growth, yield and nutrients content of okra -1 and Factor- 2. Rate of salicylic acid: 0 mM, 0.75 mM and 1.5 mM. BARI Dherosh-2 was used as the test crop. Data were taken onplant height, number of branches and leaves plant -1 , length of leaves, number of flowers plant -1 , number of fruits plant -1 , individual fruit weight as well as fruit yield plant -1 , fresh weight of shoot and dry weight of shoot, N, P and K content in fruit, shoot and root. When single effect was considered, salinity adversely affected most of the growth and yield parameters and nutrient content, but application of salicylic acid elevated all the mentioned parameters except plant height. When combined effect was considered, maximum plant height -1 0 SA at final harvest, number of branches plant -1 -1 1.5 -1 -1 6 SA treatment, whereas the minimum plant height 12 SA 1.5 1.5 , number of branches plant -1 -1 -1 12 SA treatment. In all the salinity levels, it was found that foliar application of salicylic acid reduce adverse effect of salt stress.

EFFECTS OF BORON FERTILIZER AND IRRIGATION FREQUENCY ON GROWTH, YIELD AND NUTRIENT CONTENT OF MUSTARD (BARI sarisha-14) TARA, MST. ISME An experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka to determine the effect of boron fertilizer and irrigation frequency on growth, yield and nutrient content of mustard (BARI sarisha-14) during the period from November 2019 to February 2020. The experiment consisted of four levels of boron viz. control - 0 kg B ha -1 (B 0 ), 0.5 kg B ha ii -1 (B 1 ), 1.0 kg B ha -1 (B ) and 1.5 kg B ha -1 (B 3 ) and 3 levels of irrigation viz. control - no irrigation (I ), one irrigation at 25 DAS (I 1 ) and two irrigations at 25 and 50 DAS (I 2 0 ). The experiment was laid out in the two factors Randomized Complete Block Design (RCBD) with three replications. Considering the application of boron, B 2 (1.0 kg B ha -1 ) showed best performance in terms of yield and yield contributing parameters and showed highest number of siliqua plant -1 (78.78), length of siliqua (4.49 cm), number of seeds siliqua (35.89), 1000 seed weight (4.51 g), seed yield (1437.00 kg ha -1 ) and harvest index (41.80%) whereas control treatment B 0 (0 kg B ha -1 2 -1 ) gave the lowest performance. Treatment B (1.5 kg B ha -1 ) showed highest N, P, K, B content in straw and B content in seed followed by B 2 (1.0 kg B ha -1 ). Considering irrigation treatments, I (Two irrigations at 25 and 50 DAS) gave best results on growth, yield and yield contributing parameters. The highest number of siliqua plant -1 2 (77.42), length of siliqua (4.47 cm), number of seeds siliqua -1 (36.00), 1000 seed weight (4.41 g), seed yield (1422.00 kg ha -1 ), stover yield (1989.00 kg ha -1 ) and harvest index (41.44%) were recorded from I whereas control treatment I 0 gave the lowest results. Treatment I also showed highest N, P, K, B content in straw and B content in seed. Regarding combined effect, B 2 I 2 showed highest number of siliqua plant -1 (85.67), length of siliqua (4.77 cm), number of seeds siliqua -1 (39.33), 1000 seed weight (5.12 g), seed yield (1780.00 kg ha -1 ), stover yield (2107.00 kg ha -1 ) and harvest index (45.78%) while the highest amount of N, P, K, B content in straw and B content in seed were found from B treatment followed by B 2 I . Hence, the results summarized that different boron and/or irrigation levels had significant and positive effect on growth, yield contributing parameters, yield and nutrient uptake of mustard and these can be considered as essential practices for higher mustard production.

FFECTS OF PLANT VITALIZER (HB-101) ON GROWTH, YIELD AND NUTRIENT CONTENT OF TOMATO BABU, MD. SAHAN SHA A field experiment was conducted during October 2019 to March 2020 in the farm of Sher-e-Bangla Agricultural University to study the effects of plant vitalizer (HB-101) on growth, yield and nutrient content of tomato. The experiment consisted of two factors: Factor A: two tomato varieties viz. V 1 : BARI tomato-2 and V : BARI tomato-15 and Factor B: 5 levels of HB-101 plant vitalizer viz. PV 0 2 : control (0 ml PV L : 1 ml PV L -1 , PV 2 : 2 ml PV L -1 , PV 3 : 3 ml PV L -1 and PV 4: 4 ml PV L -1 . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. In case of different tomato varieties, the best performance for most of the parameters was obtained from V 2 (BARI tomato-15) and gave highest yield (59.47 t ha -1 -1 ), PV ) compared to V (BARI tomato-2) (57.87 t ha -1 ). In case of plant vitalizer, 3 ml PV L -1 (PV ) treatment showed best performance and gave highest yield (62.10 t ha -1 3 ) compared to other treatments. In case of combined treatments, V 2 PV 3 (BARI tomato-16 with plant vitalizer @ 3 ml L ) gave highest number of fruits plant -1 (28.80), single fruit weight (63.75 g), fruit weight plant -1 (1836.00 g) and yield (62.95 t ha -1 ) compared to other treatment combinations but in case of nutrients (N, P, K and S) content in tomato fruits V 2 PV showed nonsignificant variation compared to other treatments. Above all considerations, treatment combination of V 2 PV 3 (BARI tomato-15 with plant vitalizer @ 3 ml L ) can be considered as the best then other treatments which can be recommended for different tomato varieties to achieve higher yield and nutrient content.
