ESTIMATION OF A PRODUCTION FUNCTION FOR WHEAT UNDER SALINE CONDITIONS

Salinity is a major problem for irrigated agriculture in many parts of the world. Farmers face economic questions such as optimal water appl ications for given irrigation water quality, reuse of drainage water, reduction in income from using drainage saline waters and rate of mixi ng good quality water. Crop yield response to water quality and quanti ty is required to answer these questions. Therefore, this paper is con cerned with estimating a set of production functions relating wheat yi eld to initial soil salinity and water quantity and quality. Crop-wate r production functions are estimated from experimental data from wheat crop at Sampla village in Rohtak district of Haryana (India). (C) 199 8 Elsevier Science B.V.
