| Summary: | The water requirement of plants for the purposes of water resources management, water program planning, irrigation water use efficiency and to achieve the maximum yield is essential. Indiscriminate use of water and drought phenomenon in the recent years caused a serious problem for water resources management. Therefore, to determine the Nigella sativa L. water requirement a study was conducted in college of agriculture Research Farm in RaziUniversity in the city of Kermanshah during two years (2009-2010 and 2010-2011). During the investigation, the irrigation was determined by using of data logger equipment of IDRG SMS-T1. During the experiments, the soil humidity was determined in field capacity condition. The evapotranspiration was calculated using water balance equation. Finally, the Nigella sativa L. water requirement was detremined as 702.12 and 746.11mm for years 2009-2010 and 2010-2011 and average water requirement was determined as 724.11mm respectively. <br /> <br /> |
