Abstract Population growth and resources restriction have forced us to look for different methods to achieve higher crop yields In addition salt affected soils are a serious threat to the sustainability of irrigated agriculture so by using a suitable irrigation planting method we can reduce water consumption and salinity hazards The purpose of this study was to optimize an irrigation planting method for higher wheat yield and water productivity WP Regarding our objective a field experiment was conducted during 2006 2007 cropping season at Roudasht Experimental Station of Isfahan Agricultural and Natural Resources Research Center The experimental design consisted of a split split plot on a randomized complete block with three replications The experiment comprised planting wheat with three irrigation water salinities as main plots including 4 8 and 12 dS m 1 Three irrigation planting methods as sub plots namely furrow irrigated raised wavy beds with 60 cm FIRB60 and 80 cm FIRB80 furrow to furrow width and conventional flat planting FP Finally the two irrigation depths as sub sub plots embodies 0 9 and 1 1 times the evapotranspiration The results indicated that the increase in salinity of irrigation water or the decrease of irrigation water leads to the significant increase in soil salinity and sodium adsorption ratio Results also revealed that with the increase of salinity of irrigation water wheat yield components declined significantly However this decline was less significant in the FIRB methods compared to the FP system The FIRB methods had lower salinity and sodium adsorption ratio than the FP method in the topsoil As a result wheat yield components 1000 grain weight spike length and harvest index enhanced Leaf chlorophyll content and grain protein were significantly higher in the FIRB methods which can respectively produce higher 1000 grain weight and higher grain quality When wheat was irrigated with the saline irrigation water of 8 and 12 dS m 1 the FIRB60 method produced higher grain yield with less irrigation water so WP increased by respectively 14 9 and 18 4 in comparison with the FP method Based on low water consumption and high yield and WP of FIRB60 it can be concluded that FIRB60 is a suitable irrigation planting method for providing sustainable agriculture in salt prone regions with water shortage pdfMachine Is a pdf writer that produces quality PDF files with ease Produce quality PDF files in seconds and preserve the integrity of your original documents Compatible across nearly all Windows platforms if you can print from a windows application you can use pdfMachine Get yours now
