The impact of different planting methods on yield and yield component of wheat cultivar Chamran under different conditions of irrigation in the Northern Khuzestan Climate

Abstract

This paper aims at investigating the impacts of different planting methods on the yield and yield component in different irrigation conditions on wheat (cultivar of Chamran) in Khuzestan for one year in Shavoor agricultural farm located in 70 km north of Ahvaz which lies in E longitude 48˚:28 and N latitude 31˚:50 as split plots in a randomized complete blocks design with three replications. The main factor is planting method in two levels of linear and sprinkling, and the subsidiary factor comprises irrigation treatments and dry farming. Variance analysis results revealed that in both factors there is a significant effect in all characteristics except for 1000grain weight which is dependent upon genotype, while the interaction of the two factors was significant only on the characteristics of panicle number per square meter and seed number in each panicle. By examining the comparison of grain yield means and other agricultural traits, the highest significant numeric value belongs to linear planting, except for the panicle number per square meter that had completely reverse trends in both treatments. Ultimately it is concluded that besides economic considerations through decreasing the amount of seeds needed and the easier control of weeds, linear planting helps to increase grain yield by accurately adjusting the distance and depth with regard to the proper positioning of seeds through increasing the claw number and other relevant characteristics of performance.
