Response of Summer Maize Growth and Water Use to Different Irrigation Regimes

Summer maize crop development, yield, and water use characteristics under deficit conditions at different growth stages were investigated in this study using irrigation regime treatments the seedling (S), jointing (J), tasseling (T), grain filling (F) 2018 2019 China. Ten set, including three-irrigation application intervals (JTFi, STFi, SJFi, SJTi), two-irrigation applications (STi, JTi, JFi), single-irrigation (Ti, Ji). These compared to control treatment (CK), which had sufficient provided four (SJTFi). The results showed that CK, a greater effect on plant height, whereas leaf area index, continuous an stem diameter of summer maize. Limitations terms development increased with less frequent irrigation. As decreased, yield efficiency increased, stage greatest efficiency. JTFi was optimal decline, its consumption reduced by 16.9% (p < 0.05) average. However, 17.3% 0.05). Moreover, smallest response factor value (Ky) 0.16, comprehensive score second highest after CK.
