Abstract

Corn is one of the most popular crops worldwide, including West Timor farmers. However, minimal reports on corn water productivity (WPCorn) growth exist. This research would make a remarkable contribution to fill this gap. This study aims to estimate WPCorn of West Timor to subsequently determine its total factor productivity (TFP) growth during 2000–2015. To do so, we used 16 years of balanced panel data on climate and the crop. WPCorn was estimated based on corn water use (CWUCorn). Then, SFA-MI was applied to determine TFP growth. The results showed that mean WPCorn in this region was 0.782 kg/m3 water use, the highest being 1.585 kg/m3 in the TTU district (2010), while the lowest was 0.225 kg/m3 in the Belu district (2012). Average TFP growth was 0.996, equal with efficiency change (EFC) and technology change (TEC), which was 1.000. However, during this period, there were decreases in TFP, EFC, and TEC by 5.949%, 0.557%, and 5.422%, respectively. The location of the Kupang municipal had the highest TFP growth (1.005), while the Belu district had the lowest (0.990). Corn production technology should be improved while increasing water uses efficiency to boost and sustain corn production.
