Impact of chemicals on fruit set and yield contributing characteristics of mango (Mangifera indica L.) cv. Langra

Abstract

In the present study entitled “Impact of chemicals on fruit set and yield contributing characteristics of mango (Mangifera indica L.) cv. Langra’’. The trial was conducted in 2014-2015 in Bihar Agricultural University, Sabour, Bhagalpur, Bihar. The treatments comprised calcium nitrate @ 0.06%, boron @ 0.2%, sorbitol 2.0 %, urea 3.0 %, NAA 10 ppm, potassium nitrate @ 2.0% and including one as control (water spray). The results showed a remarkable influence of different chemicals on fruit set and yield. Foliar spray of calcium nitrate at 0.06% was found to be the best treatment among seven in terms of fruit yield, length, width and volume. Spraying of boron at 0.2% improved fruit regarding minimum fruit drop percentage. Regarding cost-benefit ratio calcium nitrate @ 0.06% shows the best effect followed by boron @0.02%.
