Growth Performance and Development Attributes of Mungbean (Vigna radiata L.) as Influenced by Organic Manure and Inorganic Fertilizer

An experiment was carried out at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the period from March to June 2015 (Kharif-I season) to find out the growth performance and development attributes of mungbean (Vigna radiate L.) as influenced by organic manure and inorganic fertilizer. The experiment consisted of two factors: factor A: five levels of manures and inorganic fertilizers [T0 = Control (no fertilizer or manure), T1 = Recommended dose of fertilizer (R) (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1), T2 = R + cow dung (3 t ha-1), T3 = R + poultry manure (2 t ha-1), T4 = R + vermicompost (2.5 t ha-1)] and factor B: two mungbean varieties; (V1 = BARI Mung 5 and V2 = BARI Mung 6). The experiment was laid out in split- plot design with three replications. The growth performance and development attributes of Mungbean varieties were found significant with the combined effect of different organic manures and recommended doses of inorganic fertilizers. The largest plant height, number of leaves plant-1, number of branches plant-1, dry weight of plant, minimum days to first emergence, 80% emergence, 80% flowering and 80% pod maturity (46.05 cm at 55 DAS, 24.16 at 55 DAS, 7.92 at 55 DAS, 40.68 g at 55 DAS, 1.80 days, 3.16 days, 32.21 days and 46.56 days, respectively) were found from the combined effect of V2 varieties with T4 treatment. Among the different treatment combination T4 [(recommended doses of fertilizer + vermicompost (2.5 t ha-1)] showed the best results. So, BARI Mung 6 performed the best performance with the application of vermicompost @ 2.5 t ha-1 with the recommended dose of fertilizer.
