Abstract

This study aims to determine the effects of biochar application and different irrigation levels on the growth, yield, and water use efficiency of maize in Vertisol of Naibonat in Kupang Regency. We used a completely randomized single factor experiment of four irrigation levels at 100%, 90%, 80%, and 70% of the field capacity. Each experimental unit was replicated six times. The observed variables are plant height, number of leaves, leaf area, plant dry weight, and water use efficiency. We found that irrigation level did not significantly affect the number of leaves, while the 100% field capacity gave the best results for plant growth, leaf area, and dry weight. The 80% field capacity resulted in the highest water use efficiency.
