Abstract

The experiment was conducted in the Horticultural Garden, Faculty of Agriculture, Banaras Hindu University, during the years 1968, 1969 and 1970. N, P, and K in the form of urea, double superphosphate and potassium chloride at 1 and 2 per cent oncentrations were sprayed singly and in combinations. Urea spray had significant effects in increasing the duration of flowering and fruiting, and percent fruit set and fruit drop, and also in decreasing the percentage of fruit retention and period of maturity in both the spring and summer flushes except the percent fruit drop and fruit retention which were affected significantly by 2 per cent urea spray in spring flush only. Double superphosphate spray at 1 and 2 per cent concentrations significantly increased the duration of fruiting in both the flushes, duration of flowering and per cent fruit set in summer flush and duration of flowering and percentage of fruit set under 2 per cent in spring flush only. Potassium chloride spray at 1 and 2 per cent concentrations significantly increased the duration of flowering and fruiting and percentage of fruit set in summer flush, and also duration of fruiting and period of maturity under 2 per cent spray in spring season. Combinations of N×P, N×K, and P×K also showed significant effects on duration of fruiting and percentage of fruit set.
