Effect of chemicals on fruit retention of mango (Mangifera indica L.) Cv. Kesar

Abstract

The present investigation entitled “Effect of chemicals on fruit retention and quality of mango (Mangifera indica L.) Cv. Kesar” was conducted at Fruit Research Station, Himayatbagh, Aurangabad during the year 2016-17. The objective of this experiment was to improve the fruit retention of mango Cv. Kesar by using NAA, KNO3, Urea and Triacontanol. The experiment was laid out in Randomized Block Design (RBD) with three replication and 13 treatments. Comprising spraying of NAA (@ each 20, 40, 60 ppm), KNO3 (@ each 2, 4, 6%), Urea (@ each 1, 1.5, 2%), Triacontanol (@ each 100, 300, 500 ppm) and control. The observations on different characters of fruit Viz, per cent fruit set per panicle, per cent fruit retention pea and marble stage, weight of fruit (g), volume of fruit (ml), Mesocarp-pulp (g), Exocarp- skin (g), Endocarp-stone (g), Number of fruit per tree, Yield per tree (kg), Yield per ha (t). Were recorded. Among the treatments, T13 Triacontanol 500 ppm recorded maximum increase in fruit set per panicle, fruit retention pea stage, fruit retention at marble stage, weight of fruit (g), volume of fruit (ml), Mesocarp-pulp (g), Exocarp-skin (g), Endocarp-stone (g), Number of fruit per tree, Yield per tree (kg), Yield per ha (t).
