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 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 ...

Abstract :

Introduction Rice is the second most important cereal in the world, and it has the highest water requirement among grain crops. Applying different irrigation methods is necessary in order to determine the best method to achieve maximum yield. Therefore, in this research, the effects of flooding and underneath conditions on chlorophyll fluorescence and agronomic traits of rice have been investi ...

Abstract :

IntroductionPurslane (Portulaca oleracea L.) is an annual and C4 plant belonging to the family portulacaceae. The plant is drought- and salt-tolerant which contains high amounts of beneficial omega-3 fatty acids and antioxidant vitamins. Nitrogen is the key element in soil fertility and crop production. Attention to the soil quality and health has increased in recent years, especially for sust ...

Abstract :

Introduction: Wheat is important plant in the economy of the world. Between wheat cultivars, bread wheat (Triticum aestivum L.) is the best cultivar for nutrition. Drought stress led to decrease production, therefore, it causes problems for nutrition and agriculture. Iran is located in dry belt of the earth and its annual rain average is 250 mm. In dry land, grain filling phase is faced with a ...

Abstract :

Introduction: Crop biomass accumulation is directly related to the amount of photosynthetically active intercepted radiation by the canopy during the crop’s cycle. The slope of this relationship represents the radiation use efficiency (RUE), defined as crop biomass produced per unit of total solar or photosynthetically active intercepted radiation (IPAR). Therefore, above-ground biomass (g m−2 ...

Abstract :

Introduction: Rice (Oryza sativa L.) is the main staple food for more than half of the world’s population. In 2011, worldwide rice production exceeded 672 million mt. Iran ranked 20th in terms of rice production in the world. Plant spacing has an important role on growth and yield of rice. Optimum plant density ensures the plant to grow properly with their aerial and underground parts by utili ...

Abstract :

Introduction: Environmental stresses are the most important factor in reducing the yield of agricultural products worldwide. Salinity and defoliation stresses are the most important environmental stresses that affect the properties and production of plants. Salinity stress is also considered as a hyperionic stress and is a major abiotic stress limiting growth and productivity of plants in many ...
