Effect of Regulated Deficit Irrigation on Nutrient Concentration in Leaves,Growth and Yield of Sorghum

Abstract

The effects of regulated deficit irrigation technique on nutrient concentration in leaves, growth and yield of sorghum was examined in a greenhouse at the School of Science and Food Technology, Universiti Malaysia Terengganu. The experiments regulated deficit irrigation (RDI) consisted of a factorial combination of irrigation regimes and soil types laid in a randomised complete block design with eight treatments for each experiment which resulted into a total of sixteen treatments. Irrigation regimes were at four levels namely: I100, I75, I50 and I25 and the soil types were at two levels namely: Rhu Tapai and Rengam soil series.
