| Abstract | ||
| The field experimental works were conducted at the experimental farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during two successive seasons of 2013/ 2014 in clay soil to evaluate the performance of utilizing gated pipes technique for cotton crop production. The objective of this research was to study surface irrigation system performance through using gated pipes under different furrows irrigation lengths L75 (75m). L100 (100m), and L125 (125m) comparing with the traditional irrigation system. Also to study the effects of irrigation system and land slope technique under different furrows lengths on cotton crop production, total water applied, water use efficiency and water application efficiency under prevailing condition in Egyptian old valley. Results showed that: The maximum value of seed cotton yield was 1846.3 kg/fad., achieved by using gated pipes under furrow length treatment L125. On the other hand, the minimum value was 1472.8 kg/fad., was achieved in case of traditional irrigation method at L125 furrow length treatment. The maximum value of the total water applied saving was achieved in case of using gated pipes irrigation system at Laser land leveling technique of 0.1% land slope under furrow length treatment L75 and its value was 1472 m3/fad./season or 34.33% of the average values of the total water applied of traditional irrigation system during the first and second seasons. Generally the results showed that the best water use efficiency was obtained in case of irrigation using gated pipes irrigation system at any treatments compared to traditional irrigation methods and increases the water use efficiency with treatment L100 furrow length. The maximum value of water application efficiency for the irrigation with gated pipes irrigation was achieved in the case of treatment L125 and its value was 85.7% under land slope of 0.10%. The results showed that using gated pipes irrigation system with Laser land leveling technique of 0.1% in three cases of furrows lengths saving irrigation water by about 33% compared to traditional irrigation method. | ||
