Abstract

In order to study the effect appropriate PLANT DENSITY and of DIFFERENT LEVELS OF IRRIGATION on YIELD AND YIELD COMPONENTS of MAIZE, a study was conducted at the Agricultural Research Station of Islamic Azad University of Tabriz in 2011.The experiment was carried out in a split based on a randomized complete block design with three replications. Different irrigation levels as main factor in 4 levels, including irrigation after 50, 100, 150 and 200 mm evaporation from class A evaporation pan and different levels of PLANT DENSITY as the subsidiary factor including 8.9, 6.7, 5.4 and 4.5 plants per square meter, were considered. Experimental results showed that interaction of irrigation level and PLANT DENSITY on Characteristics such as shoot dry weight, number of kernel/ear, 100 kernal weight and harvest index was significant, so that with increase in irrigation level and decrease of PLANT DENSITY, other characteristics were decreased. Among irrigation levels the maximum grain yield was at level of 50 mm evaporation from evaporation pan and the minimum grain yield was at the level of 200 mm evaporation from evaporation pan. The maximum yield and harvest index was in PLANT DENSITY of 6.7 plant/m2 and 741.1g/m2. With increase in irrigation period in each level of MAIZE growth caused noticeable decrease in yield and kernel/ear and this decrease was Effect of irrigation and PLANT DENSITY on grain yield and plant height were significant. The irrigation treatments, respectively, the highest and the lowest grain yield in treatments 50 and 200 mm evaporation from pan evaporation rate of 745.12 and 347.1 grams per square meter, respectively. The highest grain yield and harvest index of density 6.7 plants per square meter of 741.1 grams per square meter, respectively. Increase in irrigation period in each level of MAIZE growth caused noticeable decrease in grain yield and number of kernel/ear, and this decrease was intensified when planting density increased.
