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.
