Abstract :

IntroductionStochastical analysis can increase decision-making reliability, meanwhile increasing the flexibility of decisions. The critical role of climatic factors in land zoning on the one hand and the stochastical nature of climatic variables, on the other hand, causes the uncertainty of land suitability grading for plant cultivation, especially in dryland conditions. Golestan province has ...

Abstract :

Introduction[1]Weed management is a key issue in ecological management of agroecosystems, and weed control should be tackled primarily by altering the competitive balance between crop and weeds. This can be through measures such as the correct choice of rotation, the choice of crop species and cultivars with more competitive ability and precision nutrient management. The infestation of weeds m ...

Abstract :

Introduction[1]Conventional tillage systems disturb the soil in the long term and obstruct farmland sustainability. Hence, adoption of conservation tillage systems, for example no tillage and reduced tillage has been widely accepted in the last two decades.The use of chemical fertilizers has increased in intensive farming systems, but this brings with environmental problems. Nowadays, due to t ...

Abstract :

Introduction[1]Nowadays, identification of the yield limiting factors in the field particularly the various yield components including number of panicle per unit area, number of seeds per panicle and seed weight) is one of the most important methods to increase the production of rice. The yield gap (YG) analysis can be performed by measuring the yield related characteristics. Yield gap was est ...

Abstract :

IntroductionPoor soil fertility is one of the main problems that limit the successful agricultural production and the global economy. Therefore, it is necessary to regulate or correct poor soil fertility, by providing vital nutrients for optimum plant growth. Improving soil fertility through fertilizer can increase crop production per unit area. But excess use of chemical fertilizers, in addit ...

Abstract :

Introduction Rice (Oryza sativa L.) is one of the most important tropical cereals which is a staple food for about 50% of population around the world, including Iran. The annual grain production of rice in Iran was 2.5 million tones which provided from an area of 0.59 million ha-1. Estimates indicate that rice yield should be enhanced about 65% in the world by the year 2020, especially in deve ...

Abstract :

Introduction:Cover crops have? wide range influence on agroecosystem? as well as multiple benefits for farmers. A major benefit of cover crops is the suppression of weeds during fall and winter, which can help to reduce soil tillage and herbicide use. A cover crop is a plant that is used primarily to slow erosion, improve soil health, enhance water availability, make weeds smother, help contro ...

Abstract :

IntroductionRice is a global important food and in Asia alone is the source of food for 3.5 billion people. Such demand for rice imposes a plan to find new technology and approaches to replace old production methods. About 75% of global rice production is practiced on low lands. At field scale, rice compared to other plants receive two or three times more water and based on some calculations, ...

Abstract :

IntroductionOne of the ways to move towards sustainable agriculture is to create diversity and using intercropping of crops, cultivars and / or different isolines in agriculture. In order to increase productivity in the agricultural system, resource management and inputs also play a key role. In addition, to preserve ecological balance and stability of the system, the main goals in the intercr ...

Abstract :

IntroductionClimatic variation particularly for participation is a constraint for the crops to reach their potential productivity under rainfed conditions. Therefore soil moisture preservation by means of tillage practices and improvement of soil physical criteria, particularly through enhancement of organic matter content is crucial. For this reason soil tillage must be managed in a proper wa ...
