Abstract

This experiment indicates that a high yield of alfalfa seed, can be obtained in the Imperial Valley if water management and insects are properly controlled. Irrigations guided by tensiometer at the 50-centibar level during seed production gave the best yield in 2 years of testing. Irrigation control was obtained by using surface drip irrigation.
