EFFECT OF PHOSPHORUS AND BORON ON THE GROWTH AND YIELD OF MUNGBEAN

Abstract

The research work was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the Rabi season of November, 2019 to March, 2020 to study the effects of phosphorus (P) and boron (B) on the growth and yield of mungbean. Two factor experiments with Randomized Complete Block Design (RCBD) was followed with 9 treatments (P 0 B 0, P 1 B 0, P 0 B 1, P 0 B 2, P 2 B 0, P 1 B 1, P 1 B ii 2, P 2 B 1 and

P 2 B 2 where P , P 1 : 25 kg P ha -1 , P 2 : 50 kg P ha -1 , B 0 : 0 kg B ha -1 , B 1 : 1.5 kg B ha -1 and B ) and replicated thrice. All of the growth and yield parameters of mungbean was significantly affected and increased with increasing levels of P and B. The tallest plant (66.63 cm), maximum number of leaves plant (2.53), number of pods plant -1 -1 0 2 : 0 kg P ha : 3 kg B ha (13.87), number of branches plant (9.21), pod length (13.67 cm) , number of seeds pod (12.80) were found in P2B2 treatment combination and all the results were statistically similar with P 1 B 1 treatment. the interaction effect of P 2 B treatment results the hiegest weight of l000-seed (41.02 g), the highest seed yield (1.26 t ha 2 -1 ) and the maximum stover yield (2.33 t ha -1 ) those were statistically similar with P 1 B treatment. The results of this research work indicated that the plants performed better in P 1 2 B treatment over the control treatment (P 0 B 0 2 ) and it was also observed that statistically similar results were found in P 1 B treatment and cost effective as well. So, It can be therefore, concluded from the above study that the treatment P 1 1 B 1 (P@25 kg ha -1 and B @ 1.5 kg ha ) was found to the most suitable treatment combination for the higher yield of mungbean in shallow Red Brown Terrace Soils of Bangladesh.
