INFLUENCE OF COWDUNG AND NPK ON THE GROWTH AND YIELD OF SUMMER MUNGBEAN

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 (March to May 2007) to study the effects of cowdung and NPK on growth and yield of summer mungbean (cv. BARI mung-6). Experimental treatment included three levels of cowdung (CD) viz. 0, 2.5, 5 t CD ha 4 and four levels of NPK viz. 0, 10kg N + 8kg P ± 8 kg K., 20kg N + 16 kg P + 16 kg K and 30kg N + 24kg P + 24kg K haT'. The experiment was laid out in a Randomized Complete Block Design (RCBD) factorial with three replications. The results showed that different levels of CD and NPK had significant effects on plant height and dry weight planf' at all sampling dates. The highest number of branches plant" (2.67), number of pods plani' (12.80), number of seeds pod4 (9.15), seed yield (1.29 t haT'), stover yield (2.81 t hi'), biological yield (4.09 t ha") and harvest index (32.36 %) was obtained from the application of 2.5 t CD ha". Application of 20 kg N, 16 kg P and 16 kg K ha" produced the highest number of branches plant" (3.00), number of pods plant" (14.45), number of seeds pod" (920), seed yield (153 t ha"), stover yield (2.89 t ha"), biological yield (4.42 ha") and harvest index (34.62 %). The combination of 2.5 t CD ha" X 20kg N, 16 kg P and 16 kg K ha1 gave the highest number of branches plant" (3.33), number of pods plant" (14.63), number of seeds pod 4 (9.21), seed yield (1.55 t ha"), stover yield (2.99 t ha'), biological yield (4.54 t ha") and harvest index (34.14 %).
