  Irrigation scheduling, flow rate and cut-off time are the three field irrigation variables currently affecting irrigation performance of Tendaho Sugar estate (Northeast of Ethiopia). As result, the study was initiated with the objective of improving existing irrigation scheduling and determining significant decision variables (flow rate and cut-off time). The long year’s climatic data were collected and analyzed by CROPWAT8.0 software to calculation of the right amount of water needed for the irrigation of crop fields, and soil samples were collected from representative cane fields to analyze soil characteristics. Parshall flumes were used to measure inflow rates at each field. The results of irrigation scheduling have showed slighter irrigation intervals than existing intervals. Therefore, to improvement of irrigation scheduling have proposed based on soil, crop ages and climat.. Read More»
