EVALUATION OF DIFFERENT CONCENTRATIONS OF TARZEC AND AXIAL HERBICIDES AND SEEDING RATES ON WHEAT (TRITICUM AESTIVUM L.) GROWTH, YIELD, AND WEED CONTROL

Wheat (Triticum aestivum L.) is one of the most important cereal crops in the world and has a necessary role in the human diet and global food sustainability. Moreover, it is a food source for more than 40% of the world's population. One of the production problems is the estimation of appropriate plant densities and weed plants. Therefore, an experiment was carried out for the agricultural season 2022-2023 in two locations, Al-Jarn village/Nimrud district/Nineveh Governorate and Bartella district, to evaluate the efficiency of concentrations of herbicides "TARZEC" and "AXIAL" and seeding rates on the growth and yield of wheat and companion, The results showed that the seeding rate of 160 kg h1 recorded the best seed rate for the number weight weed, number of weeds, the number grains, the number spikes, and the grain yield amounted to 6.03, 2.05 weed.m2, 3.38, 6.61 g.m2, 38.59, 37.17 grain.spike1, 504.1, 474.1 spike.m2, and 578.73, 516.06 g.m2 for the above traits and for both locations respectively. weed control efficiency in weeds number and weight TARZEC 100% and AXIAL 100% was 65.3%, 60.94%, 64.4%, 51.54%, 55.74%, 53.0%, 46.53% and 49.44% respectively. the highest rate of the number of grains in spike, the number of spikes and the yield of grains was recorded with the TARZEC 100%, TARZEC+25, AXIAL 100% and AXIAL +25. Conclude from the above that the best seeding rate is 160 kg.h in addition to the use of herbicides "TARZEC" and "AXIAL" in the recommended Concentrations.
