Influence of Pre-harvest Foliar Application of Micronutrients and Sorbitol on Pollination, Fruit Set, Fruit Drop and Yield in Mango (mangifera Indica L.) Cv.ALPHONSO
Subscribe/Renew Journal
An experiment was carried out to study the influence of pre-harvest foliar application of calcium (0.06 %), boron(0.02%) and sorbitol (2 %) along with a control on pollination, fruit set, fruit drop, fruit growth parameters and yield of mango cv. ALPHONSO. The result revealed that maximum pollen viability (89.69%), germination (56.30%) and pollen tube growth (158.99μm), fruit set at pea stage (0.66%), fruit retension (2.23%),fruit length (9.98 cm), breadth (7.86 cm), weight (268.29 g), fruit volume (258.24 cc), number of fruit per tree (166.00) and yield per tree (44.60 kg)and minimum fruit drop (97.77%)were obtained under the foliar spray of boric acid (0.02%).
