A global meta-analysis of yield and water productivity responses of vegetables to deficit irrigation

Abstract Strategies promoting efficient water use and conserving irrigation water are needed to attain water security to meet growing food demands. This meta-analysis study evaluated the effect of deficit irrigation (DI) strategy on eight vegetables to provide a quantitative estimate of yield and wa...
