Summary

Water-use efficiency and forage yield of irrigated oats depend to a large extent on water application during initial growth. Root distribution, growth and fodder yield of oats as influenced by time and amount of first irrigation were studied in the field for 2 years. Root-weight density of each layer, profile-root-weight density and yields decreased progressively when the first irrigation was delayed. Application of a small amount of irrigation (20 mm) at day 25 proved to be better than applications of 50 or 70 mm at later stages.
