Combining Field and Simulation Studies to Improve Fertilizer Recommendations for Irrigated Rice in Burkina Faso
estimated at 4.0 to 4.5 t ha 1 (Illy, 1997; Wopereis et al., 1999), and in general two crops per year are grown. Development of improved fertilizer recommendations entirely based This compares to average yields in the Sahelian and on field experiments is time-consuming and costly. We employed a comSavannah regions of 3.0 to 5.5 t ha 1. The cropping bination of two simulation models and selected...
متن کاملAssessing and Improving Water Productivity of Irrigated Rice Systems in Africa
(eds M.C.S. Wopereis et al.) 265 supply sufficient water for drinking water and irrigation. Exceptions are the Volta River basin in West Africa and the Orange and Limpopo River basins in Southern Africa, where population density and large-scale irrigation systems put great strains on water resources availability (Ravenga et al., 2000). There is large untapped irrigation potential in SSA. IFPRI ...
متن کاملMeasurement of Vertical Water Percolation Through Different Soil Textures of Paddy Field During Rice Growth Season
The water percolation loss beyond root zone in the soil is one of the important parameters to determine water requirement of rice plant. If the amount of water percolation rate into the soil is estimated more carefully, determination of water requirement will be evaluated better and designing for system of irrigation, drainage and related establishments will be more easily done. The purpose of ...

متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
