Abstract

Field experiments conducted during 2002–2005 with various fertilizer rates and their split application using groundnut varieties VRI2 and BS 9002 as test crops. The results revealed that, application of 34: 64: 108 kg NPK ha−1 at a split of 50: 25: 25 percent N and K at basal, flowering and peg forming stage and 100 per cent P as basal found to be an optimum dose for getting maximum pod yield. Increasing levels of respective nutrient increased the nutrient content in the crop and its uptake.
