Evaluation of soil erosion by existing models is needed as an important tool for managerial purposes in designation of proper water and soil conservation techniques. The present study aimed to assess ...
Evaluation of pan coefficient equations in a semi-arid Mediterranean environment using the ASCE-standardized Penman-Monteith method
Pan Evaporation Reference Evapotranspiration ASCE-Standardized Penman-Monteith
2013/2/27
Reference crop evapotranspiration (ETo) is essential for irrigation, water resources management and environmental assessment. The indirect estimation of ETo is based a) on energy budget approach using...
Long-term effects of management systems on crop yield and soil physical properties of semi-arid tropics of Vertisols
Broadbed and Furrow System Minimum Tillage Long-Term Experiment Sustainability
2013/3/5
Long-term experiments can be used to assess management induced changes in soil properties and sustainability of the management system in terms of the productivity. Such data are scanty, especially in ...
Water use efficiency and yield of winter wheat under different irrigation regimes in a semi-arid region
Water Use Efficency Yield Surface and Drip Irrigation
2013/3/4
In irrigation schemes under rotational water supply in semiarid region, the water allocation and irrigation scheduling are often based on a fixed-area proportionate water depth with every irrigation c...
Soil Mineral N Dynamics in a Maize Crop Following Different Soil Fertility Amendments in Different Soil Fertility Status in Sub-humid and Semi-arid Regions in Central Kenya
N uptake Organic inputs Nitrate ammonium
2010/11/15
Nitrogen is the major limiting nutrient in crop production and it is also one of the nutrients that is easily lost from the plant-soil system in various ways. Due to this, N supply, N management and N...
Soil Management Systems Improve Water Use Efficiency of Rainfed Rice in the Semi-Arid Tropics of Southern Lombok,Eastern Indonesia
Evaporation Paddy Precipitation Water requirement
2009/7/24
Rice (Oryza sativa) grown on rainfed Vertisols in the semi-arid tropics of southern Lombok, Eastern Indonesia, is usually flooded in the short wet season, creating a considerable demand for water. How...

Agroforestry demonstrations hedges intercropping Kenya semi-arid land
2009/3/3
Hedged agroforestry (AF) demonstration plots with maize/bean intercrops were studied at Matanya in Laikipia district, Kenya, between 1991 and 1995 inclusive, to understand crop yield behaviour due to ...
Use of CORINE Methodology to Assess Soil Erosion Risk in the Semi-Arid Area of Beypazari, Ankara
Modified Fournier Index rainfall variability rainfall frequency soil erosion risk assessment CORINE
2009/1/12
Soil erosion is one of the major threats to the conservation of soil and water resources in the semi-arid and arid regions of Turkey. Therefore, there is a need to accurately assess soil erosion and a...
