EFFECT OF GA3 IN COMBINATION WITH UREA PHOSPHATE AND BA ON YIELD AND PHYSICAL QUALITY PARAMETERS OF GRAPE CV. THOMPSON SEEDLESS

Abstract

Effect of GA3 in combination with Urea Phosphate and BA on yield and quality parameters of grape cv. Thompson Seedless was evaluated. GA3 in combination with Urea Phosphate and BA at different concentrations were applied at two stages that were pre bloom and berry set. Among all the treatments, application of GA3 @ 30 ppm at prebloom and 30 ppm GA3 + 10 ppm BA at berry set stage and 40 ppm at pre bloom and 30 ppm GA3 + 10 ppm BA at berry set stage, effectively improved fruit physical parameters such as bunch weight (570.87 g), number of berries per bunch (166), berry length (2.43 cm), berry breadth (1.90 cm), berry weight (3.41g) and yield (21 kg/vine). The data from this study indicated that GA3 along with Urea phosphate and BA influence the yield and quality of grape cv. Thompson Seedless
