EFFECT OF COWDUNG AND INORGANIC FERTILIZERS ON THE GROWTH AND YIELD OF MUNGBEAN (BARI mung-6)

Abstract

An experiment was conducted at the experimental field of the farm of Sher-e-Bangla Agricultural University during the period from March to june (kharif season) of 2020 to study the effect of cowdung and inorganic fertilizers on growth and yield of mungbean (BARI Mung 6). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The 7 treatment combinations of cowdung manure and inorganic fertilizer were T 0 viii

- Control, T 1 - 100% Recommended fertilizer dose (RFD), T 2 - 6 ton cowdung ha -1 , T 3 - 80% recommended dose of inorganic fertilizer and 20% cowdung ha -1 T 4 - 60% recommended dose of inorganic fertilizer and 40% cowdung ha -1 T 5 - 40% recommended dose of inorganic fertilizer and 60% cowdung ha -1 , T 6 - 20% recommended dose of inorganic fertilizer and 80% cowdung ha 1 -1 . At 30 DAS and at harvest highest plant height (48.22cm), number of leaves plant and branches plant -1 were found from the combination of 80% cowdung manure and 20% inorganic fertilizer (N, P, K). Maximum numbers of pods plant (19.25), seeds pod -1 (10.42) and 1000-seed weight (43.44g), seed yield (1.42 t ha -1 ) were recorded in 20% cowdung manure and 80% inorganic fertilizer. Highest pod plant (19.25), 1000seed weight (43.44g) and seed yield ha -1 (1.42 t ha -1 ) was recorded in 20% cowdung + 80% of optimum dose of inorganic fertilizer and it was statistically disimilar with the treatment of 40% cowdung manure + 60% of optimum dose of inorganic fertilizer. It was observed that, for the above parameters; 80% optimum dose of inorganic fertilizer + 20% of optimum dose of Cowdung showed better results than sole 100% inorganic fertilizer. Lowest values for all of the growth and yield parameters obtained from the treatment using control.
