Abstract

This study was conducted to investigate the effects of applying DEFICIT IRRIGATION on aboveground biomass, leaf area and root biomass for MAIZE HYBRID 704 SINGLE-cross. Experimental treatments included 4 different irrigation levels, 5 growth stages with three replicates in a completely randomized factorial statistical design. Aboveground biomass, leaf area and root biomass in 4 longitudinal sections of root length were measured at different growth stages. Results indicated that different irrigation levels had significant effect on aboveground biomass, leaf area, root biomass of sectional root lengths and total root biomass (P<0.05). The maximum aboveground biomass, leaf area and total root biomass were observed at milk stage in both years. These values were 318.9 and 465.1gr for aboveground biomass, 6497 and 6533cm2 for leaf area and 32.3 and 36.6gr for total root biomass in 2009 and 2010, respectively. The optimum level of water stress with maximum root biomass for maize can provide useful information for scholars and engineers to increase irrigation water use efficiency under DEFICIT IRRIGATION management.
