Combined Influence of Bud Load and Micronutrients on Physico-chemical Traits of Grape cv. Sahebi

The study on the combined influence of bud load and micronutrients on physicochemical traits of grape cv. Sahebi was carried out in model grapevine orchard of the Department of Horticulture at Kralbagh, Tehsil Lar Distt. Ganderbal (J&K) for two consecutive years to standardise the bud load and micronutrients application for improving physic-chemical traits in grape cv. Sahebi. The experiment consisted of 15 treatments with 3 levels of budload B1 (96 buds/vine), B2 (128 buds/ vine) and B3 (160 buds/vine), 3 levels of micronutrients viz. M1 (Solubor 0.1%), M2 (ZnSO4 0.4%) and M3 (Solubor 0.1% + ZnSO4 0.4%) applied two weeks before bloom and their 9 combinations (B1M1 , B1M2, B1M3, B2M1, B2M2, B2M3, B3M1, , B3M2, , B3M3 ) replicated thrice with a double plot size in a completely randomized block design. Among the different treatments budload B2 (128 buds/vine) recorded maximum fruitful shoots, bunch length, berry length, total soluble solids /acid ratio and minimum shot berry percentage Maximum fruitful shoots, number of bunches, bunch diameter, berry length, berry diameter, total soluble solids/acid ratio, ascorbic acid and shot berry percentage was observed in micronutrient M1 (Solubar-0.1%). The combination of B2M1observed highest fruitful shoots, berry length, total soluble solids /acid ratio, ascorbic acid, and lowest shot berry percentage. Thus it was concluded that budload B2 (128 buds/vine), M1 (Solubor 0.1%) and their combination B2M1 proved to be the best for improving physico–chemical traits of grape cv. Sahebi.
