Abstract
Two field experiments were conducted at the farm of Kuotor - EL- Gharbia Governorate during 2016/2017 and 2017/2018 growing seasons to study the effect of three sowing methods [Broadcasting on beds method, Drilling on beds method and Hills on beds method] and three seeding rates (45, 52.5 and 60 kg seeds/fad.) on growth, yield and yield components of three bread wheat cultivars (Triticum aestivum L.). Giza 171 variety gave the highest values of heading date, flag leaf area, date of maturity, plant height, spike length, No. of spikes/m2, No. of grains/spike, grain weight/spike, 1000-grain weight, biological yield, grain yield and straw yield compared with the other varieties in the first and second seasons. Regarding hills sowing method was better for growing wheat plants and gradually increased grain yield/fad than drilling and broadcasting methods. planting by hills on bed method gave the highest values of flag leaf area, plant height, spike length, No. of spikes/m2, No. of grains/spike, grain weight/spike, 1000-grain weight, biological yield, grain yield and straw yield compared with the other sowing methods in both seasons. The highest values of flag leaf area, spike length, No. of grains/spike, 1000-grain weight, grain weight/spike and grain yield were found with seed rate (45 kg/fad.) in both seasons. The highest values of grain yield/fad were found when applied the cultivar Giza 171 and hill method with seed rates (45 kg/fad.) in both seasons. While the interaction of cultivar Shandaweel 1 and broadcast method with seed rate 60 kg/fad. recorded the lowest values of grain yield/fad in both seasons.
