This study determines the amount of irrigation water saved as a result of the subsidy policy to adapt from flood to drip irrigation. We developed a positive mathematical programming model (PMP) to evaluate the effect of economic incentives on farmers’ decisions to choose the type of irrigation technology, cropping pattern, and "water use" and "water consumption" in rural Garkan Shomali district...
Agriculture has two ways to increase its output, expanding the land area under cultivation and improving the yields on cultivated land. If agricultural growth and performance taken to increase the farming incomes of rural families, then a third way can be added, i.e. shifting the product composition to higher value products. For decades, it has been commented that, globally the possibilities fo...
One of the ordinary methods to protect, rehabilitate, and enhance an ecosystemfunction in arid and semi-arid areas of the world is sand dune stabilization using biologicalpractices. Plantation of species on the soil plays a great role in sustainable management ofthe ecosystem. This research studies the effects of cultivation of Haloxylon ammodendronand Atriplex canescens on physical-chemical ch...
prediction of the agricultural developmental problems has ever been one of the goals of proper agricultural development, to gain more productions from the minimum resources. the goal of this research is zoning prone area of olive cultivation with two methods: gis and genetic algorithm. also the results have been compared with the current olive cultivation areas in lorestan province and the resu...
Comparative Analysis of T. Aman Rice Cultivation under Different Management Practice in Coastal Area
Soil temperature influences crop growth and quality under field and greenhouse conditions; however, precise investigation using controlled cultivation systems is largely lacking. We investigated effects of root-zone temperatures on growth and components of hydroponically grown red leaf lettuce (Lactuca sativa L. cv. Red Wave) under a controlled cultivation system at 20 ̊C. Compared with ambient ...
Evaluation of the Surface Water Distribution in North-Central Namibia Based on MODIS and AMSR Series
Semi-arid North-central Namibia has high potential for rice cultivation because large seasonal wetlands (oshana) form during the rainy season. Evaluating the distribution of surface water would reveal the area potentially suitable for rice cultivation. In this study, we detected the distribution of surface water with high spatial and temporal resolution by using two types of complementary satel...
Article history: Received on: 25/05/2016 Revised on: 17/06/2016 Accepted on: 10/07/2016 Available online: 30/08/2016 Phospholipid is very essential in the balanced diet. The vegetarian people in the coastal area are habitant of using edible oil seeds as daily food grains. Salinity of water during cultivation decreases the accumulation of oil content (12-15%) in seeds. Present experiment was foc...
abstract due to limited water resources in agriculture, application of each strategy to economize water use and increase area under cultivation is very important. one such strategy is deficit irrigation. for optimal planning of deficit irrigation, it is necessary to determine different sensitive stages of plant water shortages. in this study the effect of deficit irrigation on growth and yield ...
