Abstract :

About 70% of the world's population's food comes directly from crops, of which the important role of oilseeds can not be denied. Oil consumption in Iran has increased in recent years due to population growth and per capita consumption, so that considering the per capita consumption of 14 kg, about 750,000 tons of oil is needed annually. However, less than 10% of this oil is produced domestically. Due to this issue, oil production through rapeseed cultivation has been considered in recent years. Drought is a threat to the successful production of crops worldwide. Drought occurs when a combination of physical and environmental factors causes internal stress in a plant and reduces production. Water stress has a negative effect on many plant processes, including photosynthesis, evaporation, accumulation and allocation of precursors, and causes a significant reduction in crop production. Therefore, one of the ways to maximize water use efficiency and increase yield per unit of water consumption is low irrigation, in which the crop is subjected to water stress at a certain stage of development or throughout the development season. On the other hand, the positive effects of potassium in increasing the resistance of plants to dehydration stress have been reported by researchers.
