There was a significant variation in N, P and K content and their uptake by different plant parts with respect to growing seasons, fertility levels and genotypes. Similarly nitrogen (N), phosphorus (P) and potassium (K) content and uptake (except fruit N and fruit P uptake) increased with increasing in the levels of soil fertility from 0 to 200% recommended dose of fertilizers (RDF). Considering yield performance of different genotypes, Ulka 686 F1 (24.9 t/ha), Jwalan (20.0 t/ha) and CA-29 (19.3 t/ha), were selected for growing at 150% RDF in the winter season. Similarly for rainy season Jwalan (12.2 t/ha), Ulka 686 F1 (11.3 t/ha) at 100% RDF and Pusa Sadabahar at 150% RDF (10.4 t/ha) were selected. Highest amount of total N, P and K uptake of 158.55, 68.51 and 195.35 kg/ha, respectively was recorded by Ulka 686 F 1 at 200% RDF. Partitioning of nutrient revealed that fruit N, P and K content increased with increasing fertility level upto 150% RDF in winter season and 100% RDF in rainy season thereafter decreased subsequently. Stem N, P and K percent increased with increasing fertility level whereas reverse case noticed in case of root N, P and K content irrespective of seasons.
