STUDIES ON YIELD CONTRIBUTION AMONG GRAFTED AND NONGRAFTED SUMMER TOMATO SEEDLINGS HASSAN, NAYMUL An experiment was conducted at vegetable research farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur in the year 2019 to assess the resistance level of rootstocks against Bacterial wilt and to evaluate grafting compatibility, seedling survivability, plant stand, growth, development, and yield at field condition for summer tomato production. Six wild rootstocks were taken to study the resistance against Bacterial wilt and most yielding rootstock respectively and BARI hybrid Tomato-8 was grafted on to six rootstocks having practiced with Integrated Pest Management approaches for evaluating field performance. The experiment consisted of following seven treatments, T 1 = WSS02 (Tomato grafted onto S. sisymbriifolium) T 2 = WSM05 (Tomato grafted onto S. torvum) T 3 ii = WSM06 (Tomato grafted onto khag-1) T 4 = WSM07 (Tomato grafted onto Khag-2) T 5 = WSM08 (Tomato grafted onto Khag 3) T 6 = WSM04 (Tomato grafted onto EG 203) T 0 = BARI Hybrid tomato-8 (Control). Two rootstocks were showed resistant against Bacterial wilt and yield showed better than control as well as any other treatments. T 1 (WSS02-S. sysimbriifolium) & T2(WSM05 S. torvum) found to be the best where higher yield was obtained from the treatment T2(WSM05 S. torvum) (34 ton/h) and T 1 (WSS02-S. sysimbriifolium) (29 ton/h). Therefore, tomato may be grafted onto S. torvum for higher yield & least wilt infestation. Thus, it may be suggested for better yield and safe tomato production in the wilt prone areas of Bangladesh during summer.

GROWTH AND YIELD PERFORMANCE OF YARD LONG BEAN (Vigna unguiculata var. sesquipedalis) INFLUENCED BY NUTRIENT MANAGEMENT AND AUXIN NAHID, RIDWANA AFRIN The field experiment was conducted at the Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka during the period from March, 2019 to July, 2019 to study the effects of different levels of nutrient management and growth regulator Auxin on the growth and yield of Yard long bean. The experiment consisted of two factors. Factor A: four levels of nutrient management; i) N 0 : control (N 0 , P 0 , K 0 ) Kg/ha ; ii) N 1 : (N 12 P 18 ii K 22 ) Kg/ha; iii) N 2 ) Kg/ha; iv) N 3 : (N 24 P 36 K 44 ) Kg/ha. Factor B: three levels of Auxin (Indole acetic acid); i) I 0 : control (0 ppm); ii) I 1 : 20 ppm iii) I 2 : 40 ppm. The variety of Yard long bean was taken BARI borboti-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The results revealed that nutrient management and auxin had significant effect on the plant height, number of leaf, number of branch, number of flower, number of pod per plant, pod yield per hectare. In case of Nutrient management, highest yield (14.5 t/ha) was observed in N 2 treatment and lowest yield (9.61 t/ha) was observed in N 0 treatment . For auxin, the highest yield (12.57 t/ha) was observed from I 2 treatment and the lowest yield (9.83 t/ha) was observed from control treatment I 0 . For combined effect, N 2 I 2 treatment combination gave the highest yield (16.64 t/ha) and lowest yield (6.37 t/ha) was obtained from N 0 combination treatment. So, from the result, it may be concluded that application of 18 kg N/ha, 27 kg P/ha and 33 kg K/ha with 40 ppm auxin is the best for growth and higher yield of Yard long bean.

GROWTH, FLOWERING AND YIELD OF BULB OF TUBEROSE AS INFLUENCED BY POTASSIUM AND GIBBERELLIC ACID NIPA, FARJANA An experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207 during the period from August, 2017 to October, 2018 to find out the effect of potassium and Gibberellic Acid (GA ) on growth, flowering and yield of bulb of tuberose. The experiment consisted of two factors namely. Factor A: levels of Potassium (K 0 = Control; 0 kg K = 130 kg K 2 O/ha, K 2 = 150 kg K 2 O/ha, K 3 = 170 kg K 2 2 O/ha) and Factor B: Concentration of Gibberellic Acid (G 0 = Control, G 1 = 120 ppm, G = 150 ppm) with three replications. The experiment was laid out in Randomized Complete Block Design (RCBD). At 75 days the maximum plant height, number of leaves per plant, number of spike per plant and side shoot per plant 63.50 cm, 10.22, 16.09 and 1.90 was found from K 2 (150 kg K 2 O/ha) respectively and also 62.55 cm, 9.16, 12.67 and 1.45 was found from G (120 ppm) respectively that was significantly influenced due to the effect of potassium and Gibberellic Acid (GA ). The highest number of floret per spike 43.00 and 38.93 were found from K 2 3 (120 ppm) respectively. The highest yield of bulb (18.86 t/ha) and bulblets (20.70 t/ha) was found from K (150 kg K 2 O/ha) and G 1 2 O /ha, K (150 kg K O/ha) and the lowest from K 0 (control, 0 kg K O/ha). On the other hand the highest yield of bulb (17.21 t/ha) and bulblets (17.86 t/ha) was obtained from G 2 (120 ppm) and the lowest from G 0 (control). In respect of combined effect, K 2 G 1 1 produced maximum yield of bulb (19.36 t/ha) and bulblets (21.99 t/ha) and the lowest from K 0 G . So the present investigation exhibits that, combined effect of 150 kg K 2 0 2 2 O/ha with 120 ppm GA is suitable for growth, flowering and yield of bulb of tuberose.

INFLUENCE OF GA 3 AND BORON ON GROWTH AND YIELD OF SUMMER TOMATO ISLAM, RIAJUL A pot experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka from April 2018 to September 2018 to study the effect of GA 3 and boron on the growth and yield of summer tomato, (CV- BARI Hybrid Tomato-4). There were four concentrations of GA 3 viz. G 0 : 0 ppm, G 1 : 50 ppm, G 2 ii : 100 ppm and G 3 : 150 ppm and three levels of boron viz. B 0 : 0 ppm, B 1 : 25 ppm and B 2 : 50 ppm. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replications and there were altogether 36 pots. Application of GA 3 and boron significantly influenced the growth, yield and size of tomato. The highest yield (1600.87 g/plant) was found from G 2 and the lowest yield (678.85 g/plant) was obtained from G 0 . Due to application of boron, the highest yield (1515.31 g/plant) was obtained from B 1 and the lowest yield (794.14 g/plant) was recorded from B 0 . In case of combined effect, the highest yield (1689.44 g/plant) was found from G 2 B 1 and the lowest yield (487.41 g/plant) was found from G 0 B 0 . So, application of 100 ppm GA 3 along with 25 ppm boron was the best for growth and yield of tomato.
