Effect of Chloro Choline Chloride in different plant density on yield and yield components of corn (Zea mays cv. SC 704) under drought stress

In order to study of effect of Chloro Choline Chloride in different plant density on yield and yield component of corn Zea mays cv. SC 704 under water stress and normal irrigation a experiment conducted in basis of split split plot in Randomize Complete Block Design in Karaj(Mahdasht) in 2004. In basis of important of irrigation factors placed in two level water stress and normal irrigation in main plot, plant density factor in three level (80000, 100000, 120000 plant/ha) in sub plot and different density of CCC at three level (control, 700 ppm and 1400) in subsub plot. The CCC and interaction its with irrigation on number seed per row and number row per ear was significant. The 1400 ppm CCC treatments under water stress with rate 24.81 N seed/ ear had significant different comparison with control (21.17 N seed/ ear). The CCC to rate 1400 ppm under water stress to rate 420 g/m2 higher than control(379 g/m2). Interaction effects high plant density(120000 ha) and high density CCC(1400 ppm) caused increased of the grain yield comparison with control.
