Abstract

Water a finite and vulnerable resource of Pakistan is an essential component of ainable agriculture. Its judicial use and scheduling are the important elements for best zation of the limited water resource for successful irrigated agriculture. To achieve high use efficiency of the available water resource and to assess the sensitivity of crop growth to water stress various irrigation schedule of wheat and cotton crops were tested by ucting field experiments supported by one dimensional transient numerical model study numerical model study greatly reduced the field trials which otherwise were impractical tested in the field due to large requirements of space labor and expenses. Field experiments were conducted on calcarious clay soil located at Agriculture earch Institute. Tandojam Sindh during Rabi 1995 96 1996 97 and 1997 98 and Kharif 7 to quantify the effects of different irrigation treatments on wheat ( variety TJ 83 ) and on ( variety NIAB
