Pre-harvest foliar spray of chemicals and mulching is an important technique to extend the self-life, marketability as well as fruit quality of mango. Keeping in view the experiment was conducted under the experimental area of BAU, Sabour, Bhagalpur, Bihar, India during the two successive seasons of 2012 and 2013. Thirty-year-old mango cv. Langra trees were used with eight treatments along with polythene mulching (during October) and per-harvest chemicals were sprayed at 30 days before harvesting of fruits of CaCl2 6H2O @ 2, 4 and 6%,Ca (No3)2@ 4%, K2SO4@ 1.0% and borax @ 1.0% in combination with polythene mulching and control. On the basis of pooled analysis of two years data. The treatment borax @ 1 % with mulching was performed better in respect of increasing the fruit weight (306.38g) and yield (132.13 kg tree-1). This treatment was also found effective for increasing the TSS (13.83 & 20.96 0Brix) and for decreasing the acidity (0.818 & 0.326%) at the time of harvest and end of storage period respectively. Whereas, the end of storage period minimum softness percentage (11.88%), minimum physiological loss in weight (15.40%) and maximum fruit marketability (87.50%) were observed with the treatment of CaCl2 6H2O@ 2% in combination with mulching. Thus, the observations indicated that per-harvest application of CaCl2 6H2O @ 2% is effective for improving the fruit shelf-life and decreasing the physiological loss in weight (PLW) whereas; the borax @1.0% with mulching proved effective for improving the fruit quality of mango cv. Langra.
