Abstract

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%).

Abstract

An experiment was conducted at Horticultural College and Research Institute, Periyakulam (Tamil Nadu) on effect of foliar application of micronutrients and sorbitol on the fruit quality and nutrient content in leaf of mango cv. Alphonso and found that the lower concentration of B, Ca and sorbitol had influenced in fruit quality compared to control. The treatment boric acid 0.02 per cent significantly increased the TSS, total sugars (%), reducing sugar (%), non-reducing sugar (%), ascorbic acid (mg/100g), carotenoids (mg/100g), sugar acid ratio and lowest values of acidity. In case of nutrient status in mango leaves N, P, K and B content were found to be higher in boric acid 0.02 per cent, while calcium content was maximum in calcium nitrate 0.06 per cent spray.
