Abstract:
The present investigation was undertaken at the Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology & Sciences, Allahabad (U.P) during two consecutive years 2015-16 & 2016-17. The experiments were laid out 4×4 Factorial in Randomised Block Design (RBD) with sixteen treatment combinations and three replications. The material used in the experiment was two micronutrients viz., Zn (Zinc sulphate) & B (Boric acid) and their different combinations with levels i.e,0.0 %, 0.4%, 0.6% & 0.8 % as foliar spray was applied twice at before and after fruit set. The observations were recorded on different traits viz., number of flowers per plant, number of fruits per plant, fruit weight (g), fruit weight per plant/ yield per plant (kg), fruit yield (q/ha), equatorial diameter of fruit (cm) and polar diameter of fruit (cm). The investigation revealed that the all characters were influenced significantly due to different levels of Zinc and boron during both the years. Foliar application of Z3 (zinc sulphate @ 0.8 per cent) before fruit set and after fruit set resulted in higher yield, fruit weight, equatorial and polar diameter during both the years. The application B3 (boric acid 0.8 %) produced maximum yield, yield attributing traits and quality parameters during both the years. Out of sixteen treatment combinations tried in this study, Z3B1 (0.8% zinc sulpahte + 0.4% boric acid) emerged as superior over all other treatment combinations in relation to physical characteristics and yield.
