Abstract

A field experimentt was conducted at a private farm in Sohag, Egypt in 2016-17 and 2017-18 to evaluate planting method, seeding rate and chemical weed control on bread wheat productivity and associated weeds. Weeding treatments were: Pyroxsulam (Pallas) herbicide and the check. Planting methods were: ridges (narrow beds); rows; dry-; and wet- broadcasting. The seeding rates were: 45, 60, and 75 kg/feddan (fed=4200 m2). Results revealed that Pallas significantly reduced the biomass of weeds by 91 % vs. the check. Wet seeding resulted in the smallest biomass of weeds vs. the dry methods. Increasing seeding rate from 45 to 75 kg/fed significantly reduced the biomass of total weeds by 65.8 %. The 75 kg/fed rate + Pallas significantly reduced biomass of weeds. Pallas significantly increased numbers of spikes/m2, grains/spike and grain yield vs. the check. Pallas increased grain yield by 5.4 ardeb (150 kg)/fed vs. the check. Ridges planting had superior effect on numbers of spikes/m2, number of grains/spike vs. other methods. As for grain yield, ridges was the first and rows the second, while wet and dry methods were significantly equal in the third class. The 75 kg/fed seed rate significantly increased spikes/m2 and grain yield. Pallas with 75 kg/fed rate gave the highest values of spikes/m2 and grain yield. Ridges method with Pallas also produced the highest grain yield. The ridges method seeded by 75 kg/fed and treated by Pallas produced the highest grain yield (10.48 t/ha) and could be recommended for producing bread wheat under similar conditions.
