West Sumatera is one of the largest mangosteen production centers in *** the 2019 harvest season,there were variations in fruit production and quality which indicated symptoms of zinc(Zn)deﬁ*** study evaluates the status of Zn for increasing the production and quality of mangosteen fruit Ratu Kamang *** study was conducting using the observation method in Lima Puluh Kota,West Sumatera from January to December *** study used ten mangosteen trees aged 23 years in three locations selected *** observed included soil properties,leaf nutrients,number of fruits;fruit,rind,aril and seed weights,percentage of fruit scars(FS)and percentage of fruit contaminated with yellow sap(YSC).The relationship between Zn concentration in leaves and fruit production and quality was analyzed using Pearson’s correlation and regression *** results showed that Zn played a role in increasing the production and quality of man-gosteen fruit at certain concentration ranges in the *** concentrations of 23.45–30.00 mg/kg play a role in increasing production,while Zn concentrations of 26.29–30.29 mg/kg play a role in increasing *** lowest incidence of FS and YSC was found in trees with Zn concentration in the leaves between 30.00–32.00 mg/*** concentration in the leaves of 30.00 mg/kg was the critical concentration in increasing the production and quality of mangosteen fruit under local cultivation *** has an antagonistic relationship to iron(Fe)and cop-per(Cu)in leaf tissue.
