The majority of lucerne seed produced in Australia and in particular the major production area of South Australia, traditionally use border check irrigation as the established irrigation system. Through the 1970’s and 80’s border check irrigation increased in the Keith region due in part to the technology at the time, the flat terrain, free draining soil type and the salinity of the ground water. Until recently, the notion of irrigating lucerne seed crops with water with salinities from 4000 – 8000 ppm with anything other than border check irrigation has not been evaluated. With the impending changes of water policy, advances in seed production and irrigation delivery technology the use of alternative irrigation systems is now a necessary consideration for irrigated lucerne seed producers. The report examines a comparison of lucerne seed and hay production between a drop tube irrigation system and a border check irrigation system.
