Abstract
Effects of 2 cv., 3 row spacings (30, 45 and 60 cm) and 3 fertilizer levels (20 kg N or 30 kg P2O5/ha or N + P) on nutrient uptake by groundnut grown on desert soil under rain-fed conditions in Rajasthan in 1966-7 were determined. N and P contents of different parts were higher in the long-duration spreading type cv. PG-1 than in the short-duration erect type cv. AK 12-24, but total uptake of N and P was similar in both cv. because of the higher pod yields of the latter. The stem, leaf, shell and seed contributed 35, 39.2, 6.2 and 19.5%, resp., to the total DM production and 17.7, 35.2, 2.3 and 44.3% to the N uptake. The N and P uptake was slightly higher at 45 cm row spacing than at 30 or 60 cm spacing. Fertilizers, especially N + P, increased the DM production, uptake and contents of N and P. The pod yield was positively correlated with N and P contents of leaves 30 days after sowing
