Floral biology and fruit set of mango (Mangifera indica L.) as influenced by different chemicals

Field experiment was carried out at mango orchard, Department of Crop Sciences, Faculty of Agriculture, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) India, during 2016-17 and 2017-18 to study the response of different mango cultivars viz. Bombay Green, Dashehari and Langra to various chemicals namely potassium nitrate, potassium di-hydrogen orthophosphate, di-potassium hydrogen orthophosphate. The results of the experiment revealed that the per cent of bud swelling, panicle emergence and flowering shoot and length of panicle were higher with application of KH2PO4-1%+KNO3-1%. In case of cultivars, mango cv. Langra produced lengthier panicle than Bombay Green and Dashehari in both treated and untreated trees. Significantly narrowest sex ratio and higher number of hermaphrodite flowers, fruit set, fruit retention per panicle and number of fruits per tree were recorded with application of KH2PO4-1%+KNO3-1% treatment. In case of mango cultivars the narrowest sex ratio and higher number of hermaphrodite flowers, fruit set per panicle and number of fruit per tree were observed with Langra.
