Abstract

A field study on mango (cv. Kesar) was conducted at Agriculture Experimental Station, Navsari Agricultural University, Paria, Gujarat during the year 2009–10 under South Gujarat tropical conditions. The objective of this investigation was to increase the fruit set and fruit yield through the different nutrient elements. The present experiment was laid out in randomized block design (RBD) with 10 treatment combinations in three replications and selected mango trees were about 10 years old. Results revealed that integrated effect of nutrients on trees was found significant on fruit setting and fruit yield. Higher fruit setting at pea (19.93/panicle) and marble stage (6.50/panicle) as well as higher value of fruit set was obtained with treatment sucrose 10% + boric acid 0.5% (T8), followed by sucrose 5% + boric acid 0.5% (T5). The fruit retention at harvest (1.13%) was also higher in same treatments. The maximum number of fruits (260.66/tree) and yield (87.89 kg/tree) were registered in sucrose 10%+boric acid 0.5% (T8) treatment followed by the treatment sucrose 5%+boric acid 0.5% (T5). On the basis of economics, maximum BCR was obtained in the treatment of sucrose 5%+boric acid 0.5% (T5).
