EFFECT OF NITROGEN, PHOSPHORUS AND POTASSIUM FERTILIZERS ON GROWTH AND YIELD OF MUNGBEAN (Vigna radiata L.)

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University farm, during April to June, 2021 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, the varieties used were BARI mung-6 and BARI mung-5 and the imposed treatments were T 0 = (control treatment), T 1 (10-40-25 NPK kg ha -1 ), T 2 (10-60-45 NPK kg ha -1 ), T 3 (20-50-35 NPK kg ha -1 ), T 4 (30-40-25 NPK kg ha ) and T 5 (30-40-45 NPK kg ha -1 ), respectively. Data on plant height leaves plant , 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 a higher seed yield (1.72 t ha -1 ) along with higher plant growth and straw yield. In contrast, BARI mung 5 produced a lower seed yield (1.57 t ha ), plant growth and straw yield. The results showed that T 3 , was the best treatment as regards of plant growth and yield produced. The seed yield produced by treatment T 3 was 74%, 38%, 9%, 7% and 8% higher over the control, T 1 , T 2 , T 4 and T 5 respectively. As for the interaction effect, V 1 T 3 showed the best results in all growth and yield contributing characters.
