Effect of growth retardants and nutrients on, fruit and quality parameter of mango (Mangifera indica L.) Cv. Alphonso

Abstract

The present investigation, entitled “effect of growth retardants and nutrients on fruitand quality parameter mango (Mangifera indica L.) cv. Alphonso” was conducted at the orchard of the Department of Fruit Science, Kittur Rani Channamma College of Horticulture, Arabhavi, Mudalagi Taluk, Belagavi District, during the year 2024-25 to evaluate the effect of growth retardants and nutrients on fruit characteristics and different quality parameters of Alphonso mango. Thirteen-year-old trees planted at 3 m × 3 m spacing were subjected to eight treatments in a Randomized Complete Block Design with three replications, each consisting of three trees. Among the different treatments, T₇ - Paclobutrazol @ 5 ml /m cd + foliar spray of Ca (NO3)2 @ 2% + KNO3 @ 2% was most effective in improving the fruit characters such as fruit length (10.98 cm), breadth (9.09 cm), weight (268.00 g), pulp weight (211.50 g), and pulp to peel (7.58) and pulp to stone ratios (7.39), highest TSS (21.49 °B), brix-to-acid ratio (153.50), with lower acidity (0.14%), maximum total sugars (13.05%),
