Abstract:

The present investigation was undertaken at Central Horticultural Experiment Station-ICAR-IIHR, Bhubaneswar during two consecutive years 2017-18& 2018-19. The experiments were laid out 2 Factorial Randomised Block Design with thirteen treatment and two season with three replications. The findings of the experiment revealed that the foliar application of various nutrients significantly increased the growth rate, flowering and fruiting characters of the plants over control. Maximum increase in plant growth in terms of plant height (17.31%) and plant spread (11.07 %) were recorded in the plants receiving SA@100 ppm (T12). Number of new emerging shoots was maximum (5.82 and 5.79) in Borax@0.6% (T6) which was found to be at par (5.73 and 5.78) with SA@100 ppm (T12) in both rainy and winter crop, respectively. Maximum number of flowers per shoot (7.74), fruit set (79.27%) and yield per plant (24.43 kg/tree) were recorded under the treatments SA@100 ppm (T12). Minimum days required for fruit set to maturity (130.00 and 131.00) were observed under the treatment ZnSO4 @ 0.6% (T3) during rainy and winter seasons, respectively. The fruit retention was found maximum (73.27% and 67.54 %) in NAA @ 100 ppm (T9), which was at par with SA@100 ppm (T12), while minimum (36.32% and 34.94 %) fruit retention was recorded in control for both rainy and winter season respectively. Application of NAA @ 100 ppm was also found to be equally good for fruit set and fruit retention during both the seasons of investigation.
