SOWING METHODS INFLUENCE ON GRAIN YIELD AND ITS COMPONENTS OF SOME WHEAT CULTIVERS UNDER DIFFERENT FERTILIZER LEVES

Abstract: Two field experiments were conducted at the Farm of Kuotor - EL- Gharbia Governorate during 2016/17 and 2017/18 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 and yield of three bread wheat cultivars (Triticum aestivum L.). Regarding hills sowing method was better for growing wheat plants and gradually increased grain yield/fad than drilling and broadcasting methods. Giza 171 variety gave the highest values No. of spikes/m2, No. of grains/spike, 1000-grain weight, biological yield, grain yield and straw yield compared with the other varieties in the first and second seasons. planting by hills on bed method increased significantly No. of spikes/m2, No. of grains/spike, 1000- grain weight/spike, biological yield, grain yield and straw yield compared with the other sowing methods in the first and second seasons. The highest values of no. of grains/spike, 1000-grain weight and grain yield were found with seed rate (45 kg/fad.), in both seasons. No. of spikes/m2, biological yield, grain yield and straw yield were affected by the interaction between wheat varieties and planting methods with seeding rates in the first and second seasons except harvest index in the first season.
