Fixed Sprinkler and furrow irrigation methods considered as the effective irrigation methods for most of field crops. Therefore, it was essential to evaluate of using these methods in irrigation of rice paddy (Oryza sativa L.) instead of the traditional flood irrigation methods which consume large amounts of irrigation water. Also, rice varietal substitutions with new developed short-duration cultivars could be an opportunity to achieve higher crop yield and water saving. From thus points, this work aims to assess the effect of using sprinkler and furrow irrigation systems on rice yield and water productivity of the two rice varieties (Sakha104 and Oraby3) compared with traditional method (basin irrigation). The results indicated that the highest grain yield was obtained under sprinkler irrigation system as the average for the two varieties reached to 10.17ton.ha-1. Oraby3 variety showed higher grain yield than Sakha104 variety. The interaction between two rice varieties and the two irrigation systems indicated that the highest value of grain yield was 10.81ton.ha-1 obtained from treatment of Oraby3 variety under sprinkler irrigation system, Also, the highest crop water productivity (1.24 kg.m-3) was recorded under the same treatment. |
