A Model To Predict The Effect Of Salinity On Crop Growth, Stuart W. Childs
A Model To Predict The Effect Of Salinity On Crop Growth, Stuart W. Childs
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A model is developed to predict the effects of soil salinity on crop growth. As an outgrowth and extension of the modelling efforts of Nimah and Hanks (1973a) and Gupta (1972), this model makes these principal assumptions in order to arrive at a quantitative relationship: 1) relative yield for a growing season is directly related to the ratio of actual and potential transpiration. 2) Water uptake by plants is in response to the water potential gradient between the plant at the soil surface and the soil surrounding the plant roots. 3) the effect of salinity on crop growth is solely …
