IntroductionMungbean [Vigna radiata (L.)Wilczek] is the most important source of protein in south and southeast Asia. This plant, have the most important sources of protein in arid and semiarid regions and played a major role in the economy of the regions. Seed mung bean has 51% carbohydrate, 26% protein, 10% moisture, 4% mineral and 3% vitamin. This crop can be successfully grown on marginal ...

Introduction: Current estimates indicate that 25% of the world agricultural lands are affected by water stress. Iran, with an annual 228 mm of rainfall, is classified as a dry region in the word. Wheat is one of the main cereal crops, cultivated for human feeding. In order to increase crop yield per unit area, largely chemical fertilizers are used. The result of these activities in recent year ...

IntroductionPotato (Solanum tuberosum L.) is an important food and cash crop ranking fourth after maize, wheat and rice annual production in the world. It is a high biological value crop that gives an exceptionally high yield with more nutritious content per unit area per unit time than any other major crops. Thus, it can play a remarkable role in human diet as a supplement to other food crops ...

Introduction: Chickpea is the most important field crop among food legumes in Iran. According to the published statistic by agricultural ministry of Iran, cultivation area of chickpea varies between 550– 900 thousand hectares that more than of 90% them cultivated under dryland condition. More than 63% of country has cold and higher cold climates and more than 60% of drylands in Iran located in ...

Introduction Sunflower (Helianthus annuus L.) is one of the most important oil crops in the world. Iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. Hence, studying the effect of irrigation on ...

IntroductionDrought stress is one of the main problems in agriculture of Iran and the world. Among the environmental limiting factors of the yield crops, drought is the most important factor to reduce production, especially in arid and semi-arid regions. Drought stress reduces water content in plant tissues, lead to growth shrinkage and some physiological and metabolic changes in them. Food le ...

IntroductionDrought stress and consequent lack of available water for plants is one of the main causes of accumulation of reactive oxygen species (ROS) in various organs of plants, which is effective in reducing the yield of cereals such as wheat. The antioxidant system, which contains various enzymes and genes, is responsible for removing and detoxifying plants from ROS. Unfortunately, genes ...

Introduction Major cultivated cotton regions of Iran are located in dry and semiarid climates, therefore water deficiency or drought stress is inseparable part of cotton production systems in these regions. So identification and introduction of drought tolerant cotton genotypes is crucial. showed that water stress decreased plant growth rate, leaf area and finally photosynthesis in cotton. In ...

IntroductionIntercropping is an ecological crop management method in which at least two plant species grow simultaneously on a field. Increased land productivity in intercropping of cereals and legumes is mainly due to the positive interaction between cereals and legumes in the rhizosphere, which increases the efficiency of soil resource utilization, especially nitrogen (N). Mixed cultivation ...
