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

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University farm, during April to June, 2012 in Kharif season with a view to evaluatthg the perfommnce of two mungbcan 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 T O = ( control treatment). T1 (10-40- T3(20-50-35 NPK kg ha'), T 4 (30-4025 NPK kg hi') and T 5

(30-40-45 NPK kg hi'), respectively. Data on plant height, 25 NPK kg hi'). T 2 (10-60-45 NPK kg ha5, leaves plant', branches plani', pods plant'', pod length, seeds pod S ', 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 hi') along with the higher plant growth and straw yield. In contrast BARI mung 5 produced the lower seed yield (1.57 t hi'), plant growth and straw yield. The results showed that 'L'3 , was the best treatment as regards of plant growth and yield produced. The seed yield produced by treatment 1 3 was 74%, 38%, 9%, 7% and 8% higher over the control, Ti, i'2, 14 and 14 respectively. As for interaction effect, V,T3 showed best results in all growth and yield contributing characters. Significant increases in N. P and K content at different fertilizer levels by inung bean plants were also observed. Additionally, highest 1.91% N content from treatment T 3, 0.22% p content from treatment T 5 and 1.35% K content from treatment f3 by mungbean were recorded.
