Comparing Actual Water Requirements Calculated By Field Methods With Water Requirements Calculated By Mathematical Models For Groundnut Crop Under Different Irrigation Systems.
\nThis research was done on groundnut crop in Tezeen agriculture research station in hama which is one of the central\u00a0 commission for agriculture scientific research centers the complete random sectors was used in designing this study with four irrigation systems: Drip irrigation ,Sprinkler irrigation, Mini sprinkler irrigation, Surface irrigation and used Mathematical Models for Calculated Water Requirements and it is Cropwat Program, IWR Program.
\nIrrigation scheduling was done for each technique at 75% of the field capacity.
\nResults shown that Drip irrigation was\u00a0 saved irrigation water 58.24%\u00a0 and it rise water\u00a0 use efficiency to 1.14 kg\/ m\u00b3and yield 5920 kg\/ ha.
\nAnd after it Sprinkler irrigation for saved irrigation water 36.65 %, and\u00a0 water\u00a0 use efficiency was0.67 kg\/ m\u00b3 and yield 5270 kg\/ ha. And after it Mini sprinkler irrigation saved irrigation water was 31.98%,\u00a0 and\u00a0 water\u00a0 use efficiency was0.58 kg\/ m\u00b3 and yield 4940 kg\/ ha comparing to surface irrigation water use efficiency was 0.39 kg\/m\u00b3and yield 4830 kg\/ ha.
\nwater consumption was Calculated By Mathematical Models( Cropwat, IWR) and Comparing With Water Requirements Calculated By Field Methods For irrigation Groundnut Crop, water consumption was 9345 m\u00b3\/ha By Cropwat Program, 8014 m\u00b3\/ha By IWR Program, 5981 m\u00b3\/ha By Drip irrigation, 8999 m\u00b3\/ha By Sprinkler irrigation, 9396 m\u00b3\/ha By Mini sprinkler irrigation, 13495 m\u00b3\/ha By Surface irrigation.
\nResults shown also that water consumption By Mathematical Models (Cropwat, IWR) was accepting with Mini sprinkler irrigation and Sprinkler irrigation systems While if we used\u00a0 Drip irrigation system we must accurate value Water Requirement with 0.64 percentage and\u00a0 Surface irrigation system with 1.44 percentage.
\nKey words: irrigation systems, Water consumption, surface irrigation, groundnut, Mathematical Models .<\/p>\n","protected":false},"excerpt":{"rendered":"
