Study on the improvement of water use efficiency in foxtail millet

The results of experiments with different varieties,seeding dates,fertilizer application,plastic film mulching,plant growth regulators and comprehensive cultivative technique systems showed that genotype of varieties,seeding dates,plant growth regulators and plastic film mulching had higher effect on the water use efficiency(WUE) of millet.To improve WUE of millet is a comprehensive cultivation technique including selection of super-variety with high WUE,proper seeding,rational fertilization and application of plant growth regulators.The tests showed that WUE of millet was increased by 26.5% to 36.9% by measurement of reducing unfruitful seeds and increasing plump seeds.WUE was increased by 33.3% to 49.3% under alternate strip cropping system.
