PERFORMANCE OF MUNGBEAN VARIETIES UNDER ORGANIC AND INORGANIC FERTILIZER MANAGEMENTS

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University farm, Dhaka to investigate the performance of mungbean varieties under organic or inorganic fertilizer managements during the period from April to June, 2017. The field experiment consisted of two factors, factor A: Variety (2); V 1 = BARI mung 6, V = Binamoog 8. factor B : Fertilizer management (5); F 1 = NPKBS (RDF), F ii

2 2 = Cowdung (10 t/ ha), F = Vermicompost (7 t/ ha), F 4 = Poultry manure (5 t/ha) and F 5 3 = Rhizobium sp (80 g/ Kg seed). The experiment was arranged in RCBD (Factorial) with three replications. Results revealed that, BARI mung 6 gave the highest seed yield (0.93 t/ha) which may be attributed to higher number of pods plant -1 (12.17), seeds pod -1 (11.8) and 1000 seed weight (42.36 g). Among different organic and inorganic fertilizer managements F (NPKSB) treatment affected the growth and yield attributes giving the highest seed yield (1.02 t/ha), pods plant 1 -1 (13.60), seeds pod (13.06), pod length (9.51 cm) which was similar with F (Poultry manure) treatment. Combined treatment of BARI mung 6 and fertilizer, V 1 F 1 4 gave the highest seed yield (1.09 t/ha), pods plant -1 (14.03) and seeds pod -1 (14.49). Combination of Binamoog 8 and poultry manure treatment (V 2 F 4 )

had greater seed yield (1.01 t/ha), pods plant -1 (13.5) and seeds pod (14.27), which was statistically similar with BARI mung 6 along with recommended fertilizers. So application of chemical fertilizer can be reduced by the application of organic fertilizer (poultry manure) without sacrificing yield.
