EFFECT OF PHOSPHORUS ON THE GROWTH AND YIELD OF MUNGBEAN

Abstract

A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, during the kharif-2 season of July, 2019 to November, 2019 to examine phosphorus (P) effect on growth and yield of mungbean. The variety, BARI Mung-6 was used in this experiment as the test crop. Data on different yield contributing characters & yield were recorded to find out the optimum levels of P for higher yield of mungbean. The treatments were six levels of P as 0, 10, 20, 30, 40 & 60 kg P ha 1 designated as P 0, P 1 , P 2 , P 3, P 4 and P respectively. The experiment with Randomized Complete Block Design consisted with three replications. Results of the study revealed that plant height increased with increasing levels of P. The application of P @ 40 kg ha 1 (P 4 5 ) produced the highest plant height (51.33, 89.17 and 100.12 cm at 30 DAS, 60 DAS and harvesting period respectively). Number of leaves plant -1 (30.33 and 26.13 at 60 DAS and harvesting period respectively), number of branches plant (1.18 and 0.93 at 60 DAS and harvesting period respectively), number of pods plant (22.80), pod length (8.90 cm), number of seeds pod -1 (12.44), weight of 1000-seeds (39.39 g), grain yield (1.57 t ha -1 ), stover yield (2.27 t ha -1 -1 -1 ) and biological yield (3.59 t ha ) were observed maximum in P 4 treatmentwhereas the control treatment (P ) showed the least performance. It was also observed that P 3 0 treatment (P @ 30 kg ha ) showed statistically similar result compared to P treatment. Therefore, it can be concluded from the above study that application of P @ 30 kg ha 4 -1 can be the economically suitable dose for the better yield of mungbean in Shallow Red Brown Terrace Soils of Bangladesh.
