ABSTRACT WITHDRAWN

Abstract:
One of the most important challenges facing humanity today is to conserve/sustain natural resources, including soil and water, for increasing food production while protecting the environment. As the world population grows, stress on natural resources increases, making it difficult to maintain food security. Long term food security requires a balance between increasing crop production, maintaining soil health and environmental sustainability. Therefore, optimizing irrigation strategies for high crop production and water use efficiency should be followed to conserve water resource in water limited regions. A wide variety of soil, nutrient, and irrigation management practices are available to farmers, most of them concerned with the basic building block of agriculture, the soil. Soil management practices include the tillage and cropping systems and crop rotations used on a farm. Therefore, sustainable crop production should be managed to enhance soil ecosystems, improving soil health and fertility and reversing degradation and pollution of land. As well as, it should be contributed to maintaining and improving, and efficiently utilizing, water resources (quantity, access, stability and quality), especially promoting practices that minimize risks of water pollution from agrochemicals and save water. In present study, the effect of land leveling, soil amendments and K- fertilizer on yield and yield components of rice have been studied. The results showed that the highest yield of grain and straw rice was obtained with using K-fertilization rate 120 kg K2O ha-1 and land levelling rate 0.05 % of surface slope. The results of this study suggest that about 20 % from the applied water for irrigation is saved by the previous treatments.
