Influence of foliar application of micro nutrients on chemical characteristics of Mango (Mangifera indica L.) cv. Amrapali

Abstract

The present investigation “Influence of foliar application of micro nutrients on chemical characteristics 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 2017-2018. The experiment was conducted in Randomized Block Design with eight treatments i.e. Control (water spray), ZnSO4 1%, FeSO4 1%, Borax 0.5%, ZnSO4 1% + FeSO4 1%, ZnSO4 1% +Borax 0.5%, FeSO4 1% + Borax 0.5% and FeSO4 1% +ZnSO4 1% + Borax 0.5% in three replications and considering one plants as a unit. The observations were recorded for chemicals attributes of mango fruit. The maximum number of fruits per shoot, fruit retention per cent, fruit yield (kg/tree), and minimum fruit drop were recorded with the application of FeSO4 1% +ZnSO4 1% + Borax 0.5% followed by ZnSO4 1% +Borax 0.5%. All the chemical characters were influenced by foliar spray of ZnSO4 1%, FeSO4 1%, Borax 0.5%, ZnSO4 1% + FeSO4 1%, ZnSO4 1% +Borax 0.5%, FeSO4 1% + Borax 0.5%, FeSO4 1% +ZnSO4 1% + Borax 0.5% in alone. The fruit length, width, fruit weight, volume, pulp weight, stone weight, pulp stone ratio were recorded maximum with the foliar application of FeSO4 1% +ZnSO4 1% + Borax 0.5% followed by ZnSO4 1% +Borax 0.5%. The maximum TSS, ascorbic acid, total sugars and minimum acidity content were observed with the foliar application of FeSO4 1% +ZnSO4 1% + Borax 0.5% followed by ZnSO4 1% +Borax 0.5%.
