Effect of Different Method Irrigation and Manure on Reduce Water Use in the Planting Grain Maize cv. KSC704

In order to study the effect of manure and irrigation methods on maize (Zea mays L. cv. KSC. 704) an experiment was conducted by using split plot in the form of randomized complete block design with four replications at Hajiabad agricultural research station in Hormozgan province in 2011 growing season. Irrigation methods in four levels: irrigation from one side of ridge until the end of the season (I1), irrigation from one side until V12 stage after two sides until the end of the season (I2), irrigation from one side until flower formation after two sides until end season (I3) and irrigation from two sides of ridge until the end of the season (I4) as main plots and different levels of manure as the second factor in four levels (0 (Control), 20, 40 and 60 tons/hectare) were randomized in subplots. Plant height, 1000 grain weight, ear traits and grain yield were measured. The results showed that effect of irrigation methods and organic fertilizers were significant on all traits. Results of interaction of treatments showed that the highest grain yield (8700 kg ha-1) was obtained at irrigation from two side of ridge until the end of the season and consumption of 60 tons/hectare of manure and the lowest grain yield (4890 kg ha-1) was obtained from one side of ridge until the end of the season and non application of manure
