Effects of Pruning and Fertilizing on Production and Quality of Mango Cultivar Gedong Gincu in West Nusa Tenggara Province - Indonesia

Pin It

Mango is a type of tropical fruit which popular among the consumers and have high commercial value. Moreover, this fruit also good for human health as contain lots of vitamins, mineral, and fiber. The largest production area of mangoes in Indonesia is East Java Province, followed by Central Java, West Java and West Nusa Tenggara. In West Nusa Tenggara Province, mangoes mostly cultivated in yards and in mixed gardens with conventional technological approaches. However, low quality of mangoes from West Nusa Tenggara Province was indicated due to lack of Good Agricultural Practices (GAP). The one being developed is Cultivar Gedong Gincu which is native to Indonesia and acceptable for both local and export purposes. This study aims to observe the effects of pruning and fertilizing on the production of mangoes as well as its post harvest quality. The experiment was conducted at farmer’s farm in the village of Mumbulsari, Sub District of Kayangan, North Lombok, West Nusa Tenggara Province of Indonesia, from January 2010 until January 2011. It consisted of seven treatments. Each treatment was repeated five times; therefore the experiment was using 35 test trees. Test trees were mangoes cultivar Gedong Gincu, average 12 years old trees and have uniform appearances. The parameters observed were varied but more focus on total number of fruits, total production, and malformation. Mango production management through a combination of 500 gram ZA fertilizer/tree + 1500 gram of SP36/tree + 1000 gram of KCl/tree + 80 gram B/tree + pruning could increase total number of fruits by 240.60% and increase total production by 269.80% compared to control treatment. In addition, use of Boron could significantly reduce the fruit sitting (malformation) from 7.22% (control) to 3.12 %.
