Abstract :

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 ...

Abstract :

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 ...

Abstract :

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 ...

Abstract :

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 ...

Abstract :

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 ...

Abstract :

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 ...

Abstract :

Introduction Drought stress and Zn deficiency are important factors affecting the quantity and quality of wheat. Zn deficiency reduces photosynthesis and disorders protein synthesis that the consequence of such process is the gathering of amino acids and amides, and disordering of carbohydrates metabolism. Besides, in such a condition, the length of plants and the size of leaves reduce due to ...

Abstract :

IntroductionSunflower (Helianthus annuus L.) is one of the most important crops grown mainly for edible oil. Sclerotinia sclerotiorum (Lib.) de Bary is a common and widespread pathogen of sunflower. Sclerotinia stem rot is one of the most damaging diseases of sunflower in world, causing average yield reductions of 10 to 20%. It causes total production loss under favorable environmental conditi ...

Abstract :

Introduction A major component in a crop growth model is leaf area development, which has crucial influence on photosynthesis and transpiration. Leaf area development involves the appearance of new leaves, expansion of the newly emerged leaves and senescence of old leaves. Modeling leaf growth has been extensively studied in many crops including cereals. Methods of predicting leaf area develop ...
