Abstract
Field experiment was conducted at Garma city in summer season 2006 on silty loam soil to study the effect of Cropping techniques and irrigation with saline water on chemical properties of soil (Ec, pH, SAR), and growth and yield of sorghum. The study included three factors viz : (A) with or without drain channels, (B) methods of Cropping (lines or furrow), and (C) plot width (2.5, 5 m) with three replicates using split– split block in Randomized block desigin. Results showed the following: 1- Using drain channels, furrow Cropping method and 2.5 m plots width have lead to significantly reduction in salinity. 2- There was not any role for drain channels, methods of Cropping and plot width in changing the pH of soil. 3- Using drain channels, furrow Cropping method, and plots width 5 m caused in increase in SAR value. 4- Using drain channels caused on increase of height, and weight of dry plant, and weight in seeds of sorghum
