EFFICACY OF PARTIAL ROOT DRYING TECHNIQUE FOR OPTIMIZING SOYBEAN CROP PRODUCTION IN SEMI-ARID REGIONS

Partial root drying (PRD) has been shown to be an efficient technique that allows water savings in areas where water availability is a major concern for agricultural production. A study was designed to compare the performance of different degrees of conventional deficit irrigation and PRD techniques on soybean production. This study was conducted at the research field of the University of Tehran in Karaj, Iran, in 2008. The study consisted of...
