Effect of bud load and fertilizer application on growth, yield and quality of Sahebi grape

Abstract

The studies on the influence of bud load and fertilizer application on growth, yield and quality of grape cv. ‘Sahebi’ were 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 bud load (B1-96 buds/ vine), B2 -128 buds/ vine and B3-160 buds/vine), 3 levels of fertilizer doses, F1=FYM (50 kg/vine) + recommended dose (NPK: 555, 227, 470g/vine), F2=FYM (50 kg/vine)+ 2 times recommended dose (NPK: 1110, 454, 940g/vine), F3=FYM (50 kg/vine)+ 3 times recommended dose (NPK: 1665, 681, 1410g/vine and their combinations replicated thrice with a double plot size in a completely randomized block design. The individual effect of as well as Fertilizer level F2 (FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine). Bud load B2 (128 buds/vine) recorded the maximum percentage of fruitful shoots per vine, number of leaves/shoot, fruit yield, bunch length, berry weight, berry length, juice content, TSS, total sugars, anthocyanin content, benefit- cost ratio and the minimum acidity. B2F2 interaction resulted in highest percentage of fruitful shoots per vine, fruit yield, berry length, TSS, total sugars, anthocyanin content, benefit- cost ratio and the minimum acidity during both years. Therefore, budload B2 (128 buds/vine), fertilizer dose F2 (FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine) and their combination is the best for improving growth, yield and quality of grape cv. Sahebi.
