Effect of supplemental irrigation with harvested rainwater on w atermelon (Citrullus lanatus) production in gravel-and-plastic mulched fie lds in the Loess Plateau of Northwest China
Abstract:Trials were conducted to examine the effects and ec onomic feasibility of supplemental drip irrigation on watermelon production in g ravel and plastic mulched fields in the Loess Plateau of northwest China in 20 01. The trial comprised four levels of supplemental drip irrigation: 0mm, 22 5 mm, 45 0 mm and 67 5 mm. The treatments were laid out in two complete randomiz ed blocks with 4 replications. The precipitation during the experiment, which co vered the watermelon growing period was 125 8 mm. The r...
