EFFECTS OF POTASSIUM AND SULPHUR ON THF GROWTH AND YIELD OF MUNGREAN (BARI Mung-6)

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm. Dhaka 1207 during the kharif season of 2012 to study the effect of potassium and sulphur on the growth and yield of Munghean (BARI Mung-6). The experimental soil was silty clay loam in texture having pH 6.14 and organic carbon content is 0.68%. Four levels of potassium (0, 15. 25 and 35 kg K ha") and three levels of sulphur (0, 3 and 6 kg S ha" ) were used in the study. The experiment was carried out in Randomized complete block design (RCBD).There were 12 treatments combinations (four levels of K and three levels of S) and three replications. The results reveald that grain and stover yield of mungbean increased with increasing levels of potassium and sulphur.The maximum significant grain and stovcr yield were obtained with the treatment combinations K2S2 (25 kg K ha" + 6 kg S ha" ) and the same treatments combinations gave the highest plant height, number of branch plant', yield attributes like number of pods plant". Number of grains pod'. weight of 1000 seeds. The N, P. K and S concentration of mungbean plant increased significantly from control to K2S2 (25 kg K hi' + 6 kg S ha") and again decreased with increasing potassium more than 25 kg K ha". Application of Potassium and Sulphur fertilizers increased organic carbon, N, P. K and S status of postharvest soil significantly.
