Influence of pre-harvest foliar application of growth regulators and micronutrients on mango cv. Himsagar

Abstract

The present experiment was carried out at Horticultural Research Station, Mohanpur, Nadia, in randomized block design to assess the effect of growth regulators (NAA and GA3) and micronutrients (ZnSO4 and borax) on fruit retention and fruit physico-chemical properties in mango cv. Himsagar. Maximum fruit retention percentage (7.25%) as well as maximum number of fruits at harvest (790.17/tree) was recorded with NAA at 40 ppm and maximum yield (217.24 kg/tree) was obtained with GA3 at 40 ppm and lowest fruit retention percentage and yield was recorded with control. Maximum length (9.28 cm), breadth (7.31 cm) and weight (283.38 g) were recorded with GA3 at 40 ppm, whereas highest TSS, total sugars and non-reducing sugar content were recorded with ZnSO4 at 1.5 per cent.
