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
