Abstract
Two field experiments were carried out at El Karada; Water Requirements Research Station, Kafr El Sheikh Governorate, North Delta, Water Management Research Institute, National Water Research Center, Egypt. During the two successive summer growing seasons of 2006 and 2007. The present study was designed to determine the most appropriate planting method and densities of rice which can maximize the yield and net profit in North Delta, Egypt. The experimental design was a randomized complete block, replicated 3 times. Six treatments were followed in the permanent field, they were: 1. TI Traditional transplanting, transplanting of seedlings rice on flat soil at distance of 20 cm between rows and 20 cm between hills, 2. T2 Transplanting of seedlings rice on flat soil at distance of 20 cm between rows and 15 cm between hills, 3. T3 Transplanting of seedlings rice on flat soil at distance of 20 cm between rows and 12.5 cm between hills , 4. T4 Transplanting of seedlings rice on flat soil at distance of 20 cm between rows and 10 cm between hills , 5. T5: Transplanting in bottom of furrows (٦0 cm) and 6. T6: Transplanting in bottom of beds (٨٠ cm). The main results in this study can be summarized as follows: from view point of water and economic it mieght be recommended to use transplanting of beds of 80 cm wide (T6) as a method of planting rice cv. “Sakha 104”under Kafer El Sheikh conditions because it is potentially high for water saving as approximately 40.13 % will be saved as average, and 2.44 % increase in grain yield/fed. At the same time, rice seedlings cv. “Sakha 104” can be transplanted on flat soil at distance of 20 cm between rows and 10 cm between hills (T4) to achieve the highest water productivity at North Delta.
