Study of eban local garlic yield potential using sustainable cultivation technology in the North Central Timor District

Abstract

This study aims to determine the effect of the best types of mulch and organic fertilizer on the growth and yield of local Eban garlic. This research was conducted from May to October 2022 on the land of the Melati Women Farmer Group (WFG), Salu Village, West Miomaffo District, North Central Timor Regency, East Nusa Tenggara, and the Laboratory of the Faculty of Agriculture, University of Timor. The experimental design used was a spit-plot design with three replications. The treatment consists of two factors: The first factor is the use of mulch, which consists of three levels, namely: TO = without mulch; T1 = organic mulch (rice straw mulch); and T2 = inorganic mulch (plastic mulch). The second factor was the use of cow manure, consisting of four levels, namely: P0 = no fertilizer (without treatment), P1 = cow manure (20 t/ha) + rice husk biochar, P2 = cow manure (20 t/ha) + biochar compost, and P3 = cow manure (20 t/ha) + biochar compost tea. The treatment combinations were T0P0, T0P1, T0P2, T0P3, T1P0, T1P1, T1P2, T1P3, T2P0, T2P1, T2P2, and T2P3 with 3 replications, so that 36 units were obtained. The results of the study showed that the combination treatment of straw mulch and cow manure (20 t/ha) plus rice husk biochar gave the best results on the local garlic yield index parameter eban (9.92).
