Yield Response of Spring Maize to Inter-Row Subsoiling and Soil Water Deficit in Northern China

摘要

BackgroundLong-term tillage has been shown to induce water stress episode during crop growth period due to low water retention capacity. It is unclear whether integrated water conservation tillage systems, such asspringdeepinter-row subsoiling with annual or biennial repetitions, can be developed to alleviate this issue while improve crop productivity.
