EFFECTS OF ORGANIC MANURES AND INORGANIC FERTILIZERS ON THE PERFORMANCE OF MUNGBEAN

Abstract

The experiment was conducted at the research field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period of mid- April to mid- July, 2012 to evaluate the effect of organic manures and inorganic fertilizers on the performance of mungbean. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experimental plots were first divided into three blocks each representing a replication. Each block then divided into six-unit plots of 3m x 2m sizes. The distance between block to block was 0.5m and plot to plot was 0.75m. The experiment comprised of two sets of factors such as two varietirs; V; = BINA Mug- 5 and V2 = BARI Mug- 6 and four fertilizer treatments: To = control, T; = Recommended dose of fertilizer, T, = 10 ton cowdung manure ha”! + inorganic fertilizer and T; = 5 ton ha” poultry manure + inorganic fertilizer. Significant variation in plant height at 35 DAS, 42 DAS, 49 DAS, 56 DAS, 63 DAS, 70 DAS and 77 DAS were found among the varieties. The highest number of pod plant” (25.33) was found in BINA Mug- 5 and the lowest number of pod plant ' (11.67) was recorded in BARI Mug- 6 variety. Among all fertilizer treatments the maximum yield of mungbean (1365 kg ha') was recorded in T; and the minimum (1255 kg ha") was in the Tp treatment of BINA Mug- 5. Maximum yield of mungbean (1310 kg ha") was recorded in T; and the minimum (1210 kg ha’') was in the To treatment of BARI Mug- 6. Finally, it might be concluded that the application of organic manures with chemical fertilizers is the best way for further mungbean production in economic point of view. But the degree of benefits obtained from different organic manures were as cow dung manure>poultry manure.
