Abstract

The field experiment was conducted at the Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, to study the effects of different levels of nutrient management and the growth regulator Auxin on the growth and yield of yard-long bean. The experiment was laid out in a randomized complete block design (RCBD) consisted with two factors.  Factor A: four levels of nutrient management; i) N0: control (N0, P0, K0) Kg/ha; ii) N1: (N12 P18 K22) Kg/ha; iii) N2: (N18 P27 K33) Kg/ha; iv) N3: (N24 P36 K44) Kg/ha. Factor B: three levels of auxin (indole acetic acid); i) I0: control (0 ppm); ii) I1: 20 ppm; iii) I2: 40 ppm. The variety of yard long bean was BARI borboti-1. The All treatments were replicated three times. The results revealed that nutrient management and auxin significantly affected the plant height, number of leaves, number of branches, number of flowers, number of pods per plant, and pod yield per hectare. In the case of nutrient management, the maximum yield (14.5 t/ha) was observed in the N2 treatment, and the minimum yield (9.61 t/ha) was observed in the N0 treatment. For auxin, the highest yield (12.57 t/ha) was observed from the I2 treatment, and the minimum yield (9.83 t/ha) was observed from the control treatment I0. For the combined effect, the N2I2 treatment combination gave the maximum yield (16.64 t/ha), and the lowest yield (6.37 t/ha) was obtained from the N0I0 combination treatment. So, from the result, it may be concluded that applying 18 kg N/ha, 27 kg P/ha, and 33 kg K/ha with 40 ppm auxin is the best for growth and a higher yield of Yard Long Bean.
