Abstract
The Pir Mahal canal (C) and water courses (WC) were divided into three equal lengths i.e. head (H), middle (M) and tail (T) sections. In each section of C and WC, one wheat field was randomly selected from which wheat grain yield was recorded and composite soil samples from 0-15, 15-30, 30-60 and 60-100 cm depths were drawn. The soil texture varied from sandy loam to sandy- clay loam in the study area. On the basis of pH~,ECe and SAR, 10,8 and 19% soils were found as salt-affected at CH, CM and CT sections, respectively. Similarly, 7, 5 and 24% sites were salt-affected at WCH, WCM and WCT, respectively. To overcome the water shortage, 31, 27 and 11 tubewells were already installed in the CT, CM and CH sections, respectively. However, tubewell count was 25, 23 and 21 in the WCH, WCM and WCT reaches, respectively. At the CH, CM and CT reaches, 82, 72 and 32% tubewells are discharging unfit water. About 48, 57 and 62% tubewells are pumping unfit water at WCH, WCM and WCT sections, respectively. The wheat yield was reasonably good (2316 to 2518 kg ha-1)' at all the sections ofthe canal and water courses. The pH«, ECe , SAR, soil P and K concentrations were not statistically correlated with wheat yield.
