| Abstract | ||
| A study was initiated in Dujailah project (Wasit Governorate) to assess the suitability of the مand characteristics for the cultivation of Wheat and Maize,(Autumn season) and alfalfa crops according to socio-economic data of production costs and gross margins for the selected crops and climatic conditions of the study area. A soil salinity map was developed for the study area using some of the predictive models developed through the use of some standard spectral vegetative and non- vegetative indices, EM38 readings, and soil salinity values measured in lab. Land evaluation was determined for the selected crops in the study area using Sys et al., 1993 proposals. Results indicated that the lands of the study area showed a clear disparity in their suitability for the cultivation of selected crops. As the results showed, the project lands were suitable for strategic crops in varying levels, including Wheat, Maize and Alfalfa crops depending on their salinity tolerance and difference date of their planting. The study area is suitable for the cultivation of all crops Alfalfa, Wheat and Maize, respectively. The results showed that the capability of the project lands was compatible with variation levels in the degree of salinity crops tolerance. The results showed the Alfalfa crop had a higher net profit compared with the Wheat and Maize crops. Gross margin was 505.000, 404.000 and 385.000 ID/Donum for the Alfalfa, Maize and Wheat, respectively. | ||
