Abstract :

IntroductionA 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 of the leaf growth has been extensively studied in many crops including cereals. Methods of predicting leaf area d ...

Abstract :

IntroductionIn recent years, rainfall deficiency was an increasing problem in most countries; which limited the production of agricultural crops. Among abiotic stresses the plants encountered, drought stress is considered as the most important limiting factor in plants growth and reproduction in natural and agricultural systems through most parts of the world; while drought stress causes 45% i ...

Abstract :

Introduction Drought is one of the major environmental conditions that adversely affects plant growth and crop yield. In the face of a global scarcity of water resources, water stress has already become a primary factor in limiting crop production worldwide. Drought is the major restriction in maize production. The plant growth reduction under drought stress conditions could be an outcome of a ...

bulk density; alkaline phosphatase; soil porosity; conservation tillage; grain yield

Abstract :

IntroductionMinimum tillage (MT) and no-tillage (NT) are collectively described as conservation tillage. Conservation tillage reduces production costs, saves water, increases soil organic matter, prevents soil erosion, mitigates greenhouse gases from the soil, improves air quality, protects wildlife habitat and biodiversity, improves production and ensures environmental safety. Cover crops are ...

AGROVOC Terms :

chlorophyll; irrigation; evapotranspiration; proline; soluble sugars

Abstract :

IntroductionDrought stress is the most important growth limiting factor for crop production. Sugar accumulation under drought stress strengthens and stabilizes cell membranes and maintains the water absorption and turgid property. Under stress conditions, proline will also maintain the turgor pressure and decreased the damages caused to plant membrane. Although proline concentrations may have ...

AGROVOC Terms :

phosphorous; dry matter; organic agriculture; zinc; nitrogen fixation

Abstract :

IntroductionNitrogen availability is an important limiting factor in low input farming systems which reduces the system productivity. Therefore, in organic farming systems, use of legume plants and composted fertilizers is crucial for balancing crop growth and nutrient demands. Biological N fixing by legume plants depends on plant morphology, density and competitive ability. In mixed intercrop ...

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 Crop models are the most important parts of ecological models. These models could provide the possibility of crop systems prediction in addition to increase the understanding of their performance. Allometric relationships of plants show the changes of growth of one part in comparison to the other parts of the plant. Determining the appropriate plant density in crops, especially wh ...

Abstract :

Introduction Canola (Brassica napus L.) genotypes with wide adaptability to environmental conditions could play a major role in Iran’s oilseed crop production. Selection of high performing genotypes is very important for developing canola cultivation. Water stress can reduce crop yield by affecting both source and sink for assimilation. Canola yield depends on genotype and environmental condit ...
