Effect of planting methods and irrigation intervals on productivity of some bread wheat cultivars

A field experiment was carried out at Experimental Farm, in Al- kalahyn, Al- Hajer village, Qeft, Qena governorate, Egypt during 2017/2018 and 2018/2019 seasons, to evaluate of three planting methods (Drilling, broadcasting and furrows) and three irrigation intervals (21 , 28 and 35 days) on productivity of three wheat cultivars ( Sids 12 –Misr 2 and Giza 168 ). The results showed that exposing wheat plants to drought stress by increasing irrigation intervals significantly decrease (1000-grain weight, grains spike weight, number of spikes/m2, grain yield (ardab/fed) (argab = 150 Kg, fed= feddan= 42002 m² = 0.420 hectares = 1.037 acres), straw yield (ton/fed) and protein %). Irrigation intervals showed highly significant difference in for all characters studies. The highest value resulted from application irrigation intervals at 21 day compare with the other irrigation intervals. Planting methods significantly affected by all a previous characters. The highest value for all studies characters resulted from using drilling method. There were highly significant differences among wheat cultivars for all characters under study. The wheat cultivar sids-12 gave of the highest values of all traits compared to the other wheat cultivars used in both seasons.
