Effect of Planting Patterns and Seeding Rate on Dryland Wheat Yield Formation and Water Use Efficiency on the Loess Plateau, China

Dryland winter wheat (Triticum aestivum L.) production plays an extremely important role in the southeast of Loess Plateau. Planting patterns have great influence on improving soil water storage and yield, should be matched with different seeding rates. In order to assess effect sowing methods drought resistance stable yield dryland wheat, a field experiment was conducted Wenxi County Wheat Experimental Base Shanxi Province, China. current study, effects three planting techniques (drilling sowing, furrow film-mulched sowing) four rates (150, 225, 300, 375 kg ha−1) were examined storage, dry matter formation, use efficiency (WUE). The results showed that (FS) (FM) treatments increased 0–300 cm layer at overwintering jointing stages. addition, FS FM consumption from maturity wheat. Furthermore, significantly accumulation mature stage, promoted its vegetative organs translocation grains after anthesis, viz., by 6.2% 7.9%, WUE 4.6% 5.3%, respectively, as compared those drilling (DS) treatments. Pearson’s correlation analysis grain had positive jointing. Moreover, positively correlated maturity. Additionally, rate 150 ha−1 could obtain higher yield. Therefore, it is strongly recommended used improve agricultural systems
