Abstract

Field experiment conducted at Hebbal, Bangalore, on TMV 2 groundnut during 1977 and 1978 Kharif seasons to study the effect of levels and method of gypsum application indicated that the DMP plant', pod yield and yield attributes increased appreciably. The increase in pod yield due to addition of different quantities of gypsum ranged from 209 to 465 kg.ha¹ over control. The corresponding increase in shelling percentage varied from 3.13 to 6.15 units and hundred kemel weight by 10.7 to 20.7 per cent. Among the various methods of gypsum application tested, appli- cation to the sides at flowering was the most effective where as broadcasting was the least effective in increasing the pod yield, shelling percentage and hundred kernal weight.
