EFFECTS OF ZINC AND SULPHUR ON THE YIELD OF MUNGBEAN

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207, during the kharif season of 2013 to study the' Effects of zinc and sulphur on the yield of Mungbcan (BAR! Mung-6)". The experimental soil pH was 5.71 and organic carbon content was 0.68%. Three levels of zinc (0, 4 and 8 kg Zn hi') and four levels of sulfur (0, 15,25 and 35 kg S hi') were used in the study. Levels of these two nutrient elements made 12 treatment combinations. The experiment was carried out in Randomized complete block design (RCBD) with three replications. The results revealed that seed and stover yield of mungbean increased with increasing levels of sulphur and zinc up to certain level. The maximum significant seed and stover yields were obtained with the treatment combination Zn2S2 (8 kg Zn hi'+ 25kg S hi'). This perticular treatment combination gave the highest seed yield (2.657 t ha"), stover yield (1.623 t hi 5, plant height (57.20 cm), number of branch plant" (2.880). yield attributes like number of pods plant" (20.09), number of seeds pod" (12.47) and weight of 1000-seeds (44.72 g). On the other hand, minimum seed and stover yields were obtained with control condition. The N, P. K and S concentration of mungbean plant increased significantly from control to Zn2S2 (8 kg Zn hi'± 25kg S ha") treatment combination and again decreased with increasing sulfur more than 20 kg S hi'. Application of zinc and sulphur fcrtili7ers increased organic carbon. N. P. K and S status of post-harvest soil significantly.
