| Abstract | ||||
| Two field experiments were conducted 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 summer seasons of 2006 and 2007. The investigation aimed to produce more rice grain yield with less water by inducing planting methods and different densities. The experimental design was a randomized complete block, replicated 3 times. Six planting methods were followed in the permanent field, they were: TI (Traditional transplanting), T2 Transplanting of seedlings rice on flat soil at distance of 20 cm. between rows and 15 cm between hills, T3 Transplanting of seedlings rice on flat soil at distance of 20 cm. between rows and 12.5 cm between hills , T4 Transplanting of seedlings rice on flat soil at distance of 20 cm. between rows and 10 cm between hills , T5: Transplanting in bottom of furrows (30 cm) and T6: Transplanting in bottom of beds (35 cm). Results showed that the total water applied were 6564, 6300, 6340, 6420, 4244 and 3878 m3/fed. and 6597, 6551, 6593, 6617, 4490 and 4124 m3/fed. for T1, T2, T3, T4,T5 and T6 treatments over both seasons, respectively. Planting in bottom of furrows and beds saved 35.34%, 33.94% and 40.92%, 39.33% of irrigation water compared with traditional planting method over the two0seasons, respectively. Maximum paddy yield (6438.00 and 6460.67 kg fed.-1) was produced by the treatment T4 in the two seasons, respectively, while the rest (of transplanting methods (T1, T2, T7, T5 and T6) produced comparatively lower grain yield. The planting method had no significant effect on (weight of 1000 grain (gm) in 2006 and 007, respectively. Maximum value of water productivity (0.80 and 0.78 LE.m-3) was produced by the treatment T4 in the two seasons, respectively, while the lowest value (0.34 and 0.33 LE.m-3) was obtained by conventional transplanting T1 during 2006 and 2007, respectively. Maximum economic efficiency (1.97 and 1.98) was achieved by the treatment T4 this is in the two seasons, respectively, while the lowest value (0.91) was recorded by conventional transplanting T1 during 2006 and 2007, respectively. | ||||
