Interaction effect of budload, fertilizer and micronutrient application on vegetative and pomological traits of grape cv. Sahebi

AbstractThe study was conducted in model grapevine orchard of Department of Horticulture at Ganderbal (J&K) for two consecutive years. The investigation comprised of 27 treatment combinations formed by combining three bud load levels (B1-96 buds/vine), (B2 -128 buds/ vine) and (B3-160 buds/vine), three 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 three micronutrient levels viz. M1 (Solubor 0.1%), M2 (ZnSO4 0.4%) and M3 (Solubor 0.1% + ZnSO4 0.4%) replicated three times with a double plot size in a completely randomized block design. The interaction B2F2M1 (Bud load B2- 128 buds/vine, fertilizer dose F2 (FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine) and micronutrient M1- (Solubor 0.1%) ) recorded the maximum percentage of berry weight, berry length, TSS, total sugars and minimum percentage of shot berries . However maximum leaf area and number of leaves was exhibited by the interaction B1M3F3 and B2M1F1 respectively. Thus the interaction B2M1F2 proved to be best in affecting the vegetative and pomological traits of grape cv. Sahebi.
