EFFECT OF VERMICOMPOST AND INORGANIC FERTILIZERS ON THE GROWTH AND YIELD OF MUNGBEAN (BARI MUNG 6)

Abstract

A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period of Kharif-1 season from March, 2020 to May, 2020 to study the effect of vermicompost and inorganic fertilizer on growth and yield of mungbean (BARI mung 6) using RCBD (Randomized Completely Block Design) with three replications. Theexperimental soil was silty clay loam in texture having pH 6.3. There were 8 treatments where, T = control condition, T 1 vermicompost, T 2 1 = 100% recommended chemical fertilizer + 0 t ha = 80% recommended chemical fertilizer + 2 t ha vermicompost, T 3 = 80% recommended chemical fertilizer + 4 t ha ix

-1 -1 vermicompost, T = 80% recommended chemical fertilizer + 6 t ha -1 vermicompost, T = 60% recommended chemical fertilizer + 2 t ha -1 vermicompost, T 6 5 = 60% recommended chemical fertilizer + 4 t ha 1 -1 vermicompost, T 7 = 60% recommended chemical fertilizer + 6 t ha vermicompost. Different plant growth and yield parameters were significantly influenced by different vermicompost and inorganic levels of fertilizer. The maximum plant height at 30 DAS, 40 DAS and harvest time (29.84 cm, 41.14 cm, 55.19 cm respectively) , number of leaves plant -1 at 30 DAS, 40 DAS and harvest time (6.76, 6.90, 8.14 respectively) , number of branches plant -1 4 (4.46) , number of pods plant

(16.90 ) , number of seeds pod -1 (10.40), pod length (8.03 cm), 1000 grain weight (44.70 g) and grain yield (1.41 t ha -1 ) were recorded by T and the lowest plant height at 30 DAS, 40 DAS and harvest time (22.79cm, 32.49 cm, 46.92 cm respectively), number of leaves plant -1 4 at 30 DAS, 40 DAS and harvest time (3.13, 3.03, 4.36 respectively) , of branches number plant -1 (2.03), number of podsplant (9.23), number of seeds pod -1 (6.63), pod length (6.86), 1000 grain weight (37.65 g) and grain yield (0.97 t ha -1 ) were recorded by T where control condition was used. The maximum grain yield (1.41 t ha -1 0 ) was obtained in T (80% Recommendation chemical fertilizer + 6 t ha -1 4 vermicompost). The minimum grain yield (0.37 t ha ) was observed in the T

0 treatment where control condition was applied.
