EFFECT OF NITROGEN, PHOSPHORUS AND POTASSIUM FERTILIZERS ON GROWTH AND YIELD OF MUNGBEAN

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University farm, during April to June, 2019 in Kharif season with a view to evaluating the performance of two mungbean varieties under different NPK fertilizer doses. The experiment was laid out in Randomized Complete Block Design (RCBD) comprising six treatments with three replications each. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the imposed treatments were T0 = (control treatment), T1 (10-40- 25 NPK kg ha-1 ), T2 (10-60-45 NPK kg ha-1 ), T3 (20-50-35 NPK kg ha-1 ), T4 (30-40- 25 NPK kg ha-1 ) and T5 (30-40-45 NPK kg ha-1 ), respectively. Data on plant height, leaves plant-1 , branches plant-1 , pods plant-1 , pod length, seeds pod-1 , 1000- seed weight, seed and straw yield were collected at 30, 45 and 60 DAS (Days after Sowing) respectively. Of the two varieties BARI mung-6 gave the higher seed yield (1.72 t ha-1 ) along with the higher plant growth and straw yield. In contrast, BARI mung 5 produced the lower seed yield (1.57 t ha-1 ), plant growth and straw yield. The results showed that, T3 was the best treatment as regards of plant growth and yield produced. The seed yield produced by treatment T3 was 74%, 38%, 9%, 7% and 8% higher over the control, T1, T2, T4 and T5 respectively. As for interaction effect, V1T3 showed the best results in all growth and yield contributing characters. Mung bean plants also observed significant increases in N, P and K content at different fertilizer levels. Additionally, mungbean recorded the highest 1.91% N content from treatment T3, 0.22% P content from treatment T5 and 1.35% K content from treatment T3
