Abstract
This investigation was carried out at private farm in El Gharbeia Governorate during seasons 2009 /2010 and 2010 /2011 to study the effects of two irrigation systems (surface and sprinkler) under three irrigation levels of 0. 6 , 0.8 and 1.0 from the ETc on applied irrigation water , yield and yield components for cumin. Data show the values of Kc during different stages .Kc increased from initial stage to mid-season then decreased to harvest stage Water applied values were 28 , 48 , 68 , 40,and 20 mm for initial , development , mid-season , late and harvest stages respectively. Data indicated that , using sprinkler irrigation system reduced the applied of amounts of irrigation water by 47.85 and 45.50 % in the two growing seasons comparing with surface irrigation. Meanwhile, yield increased by about 10.16 and 12.52 % under sprinkler system irrigation comparing with surface irrigation in first and second growing seasons respectively . While decrease water use efficiency under surface irrigation by 52.7 and 53.6% comparing with sprinkler irrigation in two seasons respectively . On the other hand as water as decreased from 1.0 to 0.8 and 0.6 from ETc (evapotranspiration), Cumin yield decreased by 14.05 and 14.25 and by 25.6 and 26.89 % in the two seasons respectively . Also , water use efficiency increased by 5.26 , 19.30 , 10.17 and 16.9 % in two seasons comparing by 1.0 ETc respectively .
