The studies on the influence of bud load and fertilizer application on leaf petiole and fruit nutrient status of grape cv. ‘Sahebi’ was carried out in Model grapevine orchard of Department of Horticulture at Kralbagh, Tehsil Lar Distt. Ganderbal (J&K) for two consecutive years. The treatment consisted of 3 levels of budload viz. B1 (96 buds/vine), B2 (128 buds/ vine) and B3 (160 buds/vine), 3 levels of fertilizer doses viz. F1 (FYM 50 kg/vine + recommended dose of NPK: 555, 227, 470g/vine), F2 (FYM 50 kg/vine + 2 times recommended dose of NPK: 1110, 454, 940g/vine), F3 (FYM 50 kg/vine + 3 times recommended dose of NPK: 1665, 681, 1410g/vine) and their combinations. Budload B1 recorded highest leaf petiole (1.62 and 1.66 %) and fruit (1.184 and 1.302 %) N content while as bud load B2 noticed highest leaf petiole (0.475 and 0.470 %) and fruit (0.068 and 0.072%) P content as well as leaf petiole (2.31 and 2.41%) and fruit (0.535 and 0.562%) K contents. Maximum leaf petiole (1.38 and 1.31%) and fruit (0.038 and 0.041%) Ca content was observed in budload B3. However budload showed no significant difference with respect to leaf petiole and fruit Zn content. Leaf petiole B (46.62 and 48.53 ppm) and fruit B (9.00 and 9.54 ppm) were highest with B3 and B2, respectively. Fertilizer level F3 registered highest percentage of leaf petiole (1.60 and 1.63%) and fruit (1.083 and 1.158%) N content. However fertilizer level F2 recorded maximum leaf petiole (0.419 and 0.447%) and fruit (0.063 and 0.068%) P, leaf petiole (1.98 and 2.09%) and fruit (0.492 and 0.482%) K contents and fruit Ca (0.036 and 0.038%), B (8.77 and 9.14%) and Zn (1.43 and 1.46%) contents respectively. Fertilizer level F1 resulted in highest content of leaf petiole Ca (1.30 and 1.32%), B (43.73 and 45.58 ppm) and Zn (48.92 and 46.09 ppm). B1F3 interaction resulted in highest leaf petiole and fruit N content. Leaf petiole P and K and fruit P, K, Ca and B contents were highest with B2F2. Leaf petiole Ca, B and Zn and fruit Zn content were highest with B3F1. Therefore it can be concluded that budload, B2 (128 buds/vine) and fertilizer dose, F2 (FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine) proved to be the best in improving leaf and fruit nutrient status of grape.
