Abstract:
A research was conducted on tomato to know the effect of pre-harvest spray of growth regulators and nutrients on yield of tomato hybrid (COTH 3) at the college orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during the period 2014-2015. Design followed was RBD with seven treatments Viz., Control (without any growth regulators and nutrients); Chlormequat chloride @ 300 ppm on 30 DAT; Mepiquat chloride @ 500 ppm on 30 DAT; Calcium sulphate @ 1% on 45 DAT; Borax @ 0.2% on 45 DAT; Chlormequat chloride @300 ppm on 30 DAT + Calcium sulphate @ 1% on 45 DAT; Chlormequat chloride @ 300 ppm on 30 DAT + Borax @ 0.2% on 45 DAT; Mepiquat chloride @ 500 ppm on 30 DAT + Calcium sulphate @ 1% on 45 DAT; Mepiquat chloride @ 500 ppm on 30 DAT + Borax @ 0.2% on 45 DAT and these treatments are replicated thrice. The observations were recorded on number of flowers per cluster, number of fruits per plant, fruit length (cm), fruit width (cm), single fruit weight (g) and fruit yield per plant (kg). Results revealed that application of chlormequat chloride @ 300 ppm on 30 DAT + Borax @ 0.2% on 45 DAT gave highest fruit yield with mean fruit yield of 3.76 kg per plant
