Effect of Tillage Systems on Growth and Yield of Bread Wheat Triticum aestivum L. and Associated Weeds

A factorial field experiment was implemented during the agricultural season 2023-2024 in two MRA locations, Sahleg and Kahreez villages. The factorial experiment included two factors. The 1st. was the locations and the second factor was the Tillage systems which was Conventional Tillage (CT) and Zero Tillage (ZT). Wheat grains (Ipaa 99 var.) were sown at a sowing rate of 100 kg hectare-1. Fertilizer was added (DAP) and Urea by 100 kg hectare-1 per each .The experiment was designed according to the factorial experiment system using a RCBD and with 3 replications, the results showed that Sahleg site was superior in all traits of yield and its components due to the difference in rainfall precipitation in it compared to Kahreez site. ZT treatment was also superior to CT in all traits of yield and its components with highly a significant difference. The highest value of grain yield was achieved in the interaction between ZT with Sahleg location at 281gm.m-2.
