| Abstract | ||||
| Two field experiments were conducted during 2003 I 2004 and 2004 2005 seasons, under saline conditions at Wadi Sudr Research Station, South Sinai D.R.C., Egypt, to study the effect of irrigation intervals (7, 12 and 17 days), sowing methods (Broadcasting, rows and furrows) on yield and yield components of wheat varieties (Sakha, 93 and Sakha 69). The results could be summarized as follows : Significant differences were detected between irrigation treatments. irrigation every 7' days significantly increased wheat yield and its components. Sowing methods showed a significant effect on all studied characters. Also, the salt tolerance of wheat increased by sowing grains on double sloping beds of furrows Wheat varieties markedly differed in their salt tolerance. Sakha 93 variety significantly surpassed Sakha 69 for all studied characters in both seasons except for plant height under saline irrigation. Pseudo, No. of tillers I plant, spike length, no. of spike letsI spike, No. of grainsI spike, grain weight I spike, 1000-grain weight, No. of spike I m2 and grain yield fed. were significantly affected by the interaction between irrigation intervals and sowing methods in the first season. While No. of grainsI spike, No. of spikes I m2 biological yield I fed. and protein % were significantly affected by this interaction in the second season. The effect of interaction between irrigation intervals and wheat varieties significantly affected No. of tillers I plant, No. of spikelets I spike, grain weight spike, grain weight! plant, 1000 grain weight, grain yield I fed , straw yield I fed biological yield I fed. and protein % in the first season. Also, that interaction had significant effect on plant height, grain weight I plant, grain yield I fed straw yield fed , biological yield I fed. and protein % in the second season. The effect of interaction between sowing methods and wheat varieties had significant effect on No. of spikelets I spike, No. of grains I spike, ’lOOO—grain weight and protein % in the first season. Similarly, plant height, grain weight plant, straw yield I fed. and protein % were significantly affected in the second season The second order interaction of irrigation intervals, sowing methods and wheat varieties was significant on No of spikelets I spike grain weight I spike, grain weight I plant, 1000 — grain weight, straw yield I led, biological yield I fed. and protein % in the first season. Plant height, straw yield I led, biological yield I fed and protein % were significantly affected by this kind of interaction in the second season . Moreover sowing wheat cultivars on furrows became more adapted to saline irrigation water. | ||||
