Foliar feeding of nutrients on fruit quality and yield of mango (Mangifera indica L.) cv. Amrapali

Abstract

A field experiment was carried out to study the foliar feeding of nutrients on fruit quality and yield of mango (Mangifera indica L.) cv. Amrapali” was conducted at Main Experiment Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during the year 2016-2017.The experiment was conducted in Randomized Block Design with seven treatments i.e. Borax 0.2%, Borax 0.4%, ZnSO4 0.2%, ZnSO4 0.4%, Urea 1.0%, Urea 1.5% and control (untreated) in three replications and considering two plants as a unit. The maximum number of fruit yield (43.00 kg/tree), fruit yield (688 q/ha) in the application of ZnSO4 0.4% followed by ZnSO4 0.2%. All the phyico-chemical characters were influenced by foliar spray of Borax 0.2%, Borax @ 0.4%, ZnSO4 0.2%, ZnSO4 0.4%, Urea 1.0%, Urea 1.5% in alone. The fruit pulp weight (166.66), pulp per cent (72.23) were recorded maximum with the foliar application of ZnSO4 0.4% followed by ZnSO4 0.2%. The maximum TSS(19.33), ascorbic acid(31.6), total sugars (17.16) and minimum acidity(0.37) content were observed with the foliar application of ZnSO4 0.4% followed by ZnSO4 0.2%.
