Effect of foliar application of humic acid, salicylic acid and novel liquid on fruit drop and yield of mango (Mangifera indica L.) cv. Amrapali

Abstract

An experiment was carried out to study the “Effect of foliar application of humic acid, salicylic acid and novel liquid on fruit yield and quality of mango (Mangifera indica L.) cv. Amrapali” at Horticultural Research Farm, and P.G. Laboratory, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand, during March to June, 2018. Treatments comprised foliar application (At 50% flower opening stage, pea stage and marble stage) of humic acid @ 1, 1.5 and 2%, salicylic acid @ 1000, 1500 and 2000 mg/l and novel liquid @ 1, 1.5 and 2% along with control. The experiment was carried out in completely randomized design with three repetitions. Among all the treatments T2 (Humic acid @ 1.5%) treatment was found most effective treatment and recorded significantly minimum fruit drop (at marble and harvest stage), While maximum in number of fruits/tree, fruit weight, fruit diameter, fruit volume and fruit yield.
