Abstract

This study aims to determine the effect of biochar and water level on increasing water use efficiency of corn crops in Vertisols from Naibonat. The soil sample was taken from Naibonat East Nusa Tenggara. This study used a complete randomized design with a single factor, namely the rate of water administration at 4 levels: 100%, 90%, 80% and 70% of field capacity with 6 replications. The parameters observed in this study were: plant height, number of leaves, leaf area, plant dry weight and water use efficiency. The research results showed that the level of water application had no significant effect on the number of leaves, the treatment of 100% water content gave the best results for plant height, leaf area and plant dry weight. The highest water use efficiency was achieved by treating 80% water content.
