PROFIT ANALYSIS OF VARIOUS GARLIC CULTIVATION INPUT PACKAGES AFFECTED BY WATER STRESS IN RAINFED HIGHLANDS OF EASTERN LOMBOK, INDONESIA

Abstract

Agricultural production influenced by several factors including climate change such as drought. Agriculture is vulnerable sector to drought because it influences cropping patterns, planting time, cropping index, production, yield quality, and profit. This study aims to investigate the profitability of garlic cultivation influenced by water stress at various input packages in the rainfed highlands of Eastern Lombok, Indonesia (1200 m above sea level). Input packages that applied were reducing use of chemical fertilizers and pesticides up to 50% from farmers’ practices. Applied input consists of 4 packages, namely P1 (farmers’ existing practices), P2, P3 and P4 as reduced and modified input packages. Field experiment was conducted in Sembalun Highlands from February to June 2018 on a 0.4 ha rainfed highlands using randomized completely block design followed by economic analysis. Parameters observed were Revenue/Cost (R/C) ratio based on fresh and dry weight yield. Results show that highest R/C ratios for fresh yield was from farmers’ existing treatment (P1) followed by P4 with the value of 1.33 and 1.28 respectively, whilst for dry yield were 1.39 and 1.36 respectively, which means that expenditure of IDR 1 will generate revenue of IDR 1.33 and 1.28 for fresh garlic bulb, while for dry garlic buld were 1.39 and 1.36 respectively. However, in term of soil sustainability issue, treatment P4 is expected to be applied. This figure decreases when compared to the production of garlic in normal conditions. Drought that occurred since early April caused the crop faced water stress and unable to provide an optimal agronomic performance and productivity which led to decreasing yield and profitability for about 40-50%.
