Impact of Foliar Micronutrient Application on Yield and Physical Traits of 'Amrapali' Mango (Mangifera indica L.)

The present study highlights about impact of Foliar Micronutrient Application on Yield and Physical Traits of 'Amrapali' Mango (Mangifera indica L.). An experiment was conducted at Main Experiment Station, Department of Horticulture, Post Graduate College Ghazipur (U.P.) during the year 2020-2024. 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 yield and physico-chemicals attributes of mango fruit. 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 phyico-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, fruits weight were recorded maximum with the foliar application of FeSO4 1% +ZnSO4 1% + Borax 0.5% followed by ZnSO4 1% +Borax 0.5%. The application of ZnSO4 at 0.4% topically to increase fruit volume showed a nearly identical pattern. The mango fruit's weight, pulp, and stone ratio were measured.
