Growth and water relations of roselle grown on bris soil under partial root zone drying

Twenty-four roselle plants were grown on BRIS soil in a greenhouse to evaluate the effects of partial rootzone drying (PRD) technique on the growth, water relation and its quality. PRD is one of the deficit irrigation methods applied in order to face global water scarcity by alternating left and r...
