Corn yield functions of irrigation and nitrogen in Central America

Irrigation Science Aims and scope Submit manuscript

Summary

This paper reports the results of a three-year field study conducted in El Salvador, Central America to develop yield response functions for corn to irrigation levels and nitrogen fertilizer. Four levels of irrigation were imposed using two application methods, furrow and trickle, in combination with four nitrogen fertilizer rates. Yields generally increased with higher levels of applied water and with higher nitrogen rates up to 200 kg N/ha, with a strong interaction between these two variables. Yield was independent of irrigation method although less water was applied with the trickle system.
