Lateral spacing in drip-irrigated wheat: The effects on soil moisture, yield, and water use efficiency

This objective of this two-year field study was to determine the effects of lateral spacing and irrigation amount on wheat yield and water use efficiency. The irrigation treatments consisted of three lateral spacings (R1, 0.30 m; R2, 0.60 m; and R3, 0.90 m) and four water amounts (W1, 3000 m3/ha; W2, 4500 m3/ha; W3, 6000 m3/ha; and W4, 7500 m3/ha). The plots were irrigated every 10 d during the growing season. The results showed that plant...
