Abstract:
A field experiment was conducted during the year 2018-19 in farmer’s field at Chennur, Kadapa district of Andhra Pradesh with a commercially important variety ‘Madhuras’ grown as a rice fallow crop to elucidate the effect of foliar application of nutrients nitrogen, potassium, calcium and boron for realising the higher yields. The study was initiated with foliar spraying of six treatment combinations namely Borax @ 1 %, KNO₃ @ 6%, CaNO₃ @ 6%, Borax @ 1% + KNO₃ @ 6%, Borax @ 1 % + CaNO₃ @ 6 %, water sprays as control with two spraying frequencies (30 and 50 days after spraying). Observations were recorded on days to first staminate flower appearance, days to first pistillate flower appearance, number of staminate flowers per plant, number of pistillate flowers/ plant, sex ratio, number of fruits per plant and yield per plant. According to the findings of the present study it can be concluded that foliar application of combination of 1% borax + 6 % calcium nitrate twice at 30 and 50 days after planting significantly enhanced the fruit yield by recording early flowering, more number of fruits per plant.
