The flowering characteristics, fruit set and fruit drop had a positive effect with the various doses of nitrogen and boron. The boron applied @ 50g/plant took minimum days for flowering (81.64 days), maximum fruit set (74.67 %), minimum fruit drop (35.05 %) and days for harvesting (98.86 days). The flowering to harvesting is decreased by 17 days with application of boron @ 50g/plant. The maximum fruit yield and fruit yield efficiency was recorded 54.37 kg/plant and 6.04 kg/plant respectively when CAN apply @ 600 g/plant. The maximum fruit weight was also obtained (330.12 g) when CAN applied @ 600 g/plant. Whereas, boron applied @ 50 g/plant produced fruit weight of 307.30 g. The highest nitrogen (1.75%) and phosphorous (0.21%) was recorded with CAN applied @ 600 g/tree. In effect of boron, maximum nitrogen (1.71%) and phosphorous (0.20%) content in leaves was obtained with application of boron @ 50 g/tree followed by boron applied @ 75 g/tree.
