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.
