Abstract
Two field experiments were carried out during the two successive growing seasons of 2017-18 and 2018-19 at Mallawy Agricultural Research Station, Agric. Res. Center, Egypt, to study the effect of weed control treatments on yield and yield components of some Egyptian bread wheat cultivars and its associated weeds. The experiments were laid out in a randomized complete blocks design (RCBD) with split-plot arrangement with four replications. The main plots were assigned to five bread wheat cultivars Misr-1, Misr-2, Shandaweel-1, Sids-14 and Giza-171, and seven weed control treatments (Pallas 4.5 % OD, Atlantis 1.2 % OD, Broadway-star 8.5 % WG, Liprator fort 36 % SC and Onostar 75 % WF ,followed by Traxsos 5% EC), as well as hand weeding twice and unweeded check were allocated in sub-plots. The results showed that the cultivars were significantly affected the dry weight of total annual weeds. The wheat cultivars were significantly different in yield and its attributes such as number of spike/m 2 , number of kernels/spike, 1000 kernels weight (g), harvest index (HI) % and grain yield (ardab/fad). The greatest value of grain yield was recorded by cv. Shandaweel-1. The highest competitive ability of cultivars (CAC%) and the least dry weight of total annual weeds was achieved by cv. Misr-2 and Giza-171. Also, the herbicides (Onostar followed Traxsos, Atlantis, Broadway star and Pallas) as well as twice hand weeding showed the highest reduction in dry weight (g) of weeds and the highest weed control efficiency (WCE%). While , the least effective herbicide was Liprator fort. The treatments of Pallas, (Onostar followed by Traxsos), Atlantis and broadway star as well as hand weeding achieved the highest increment in wheat yield and its components. The interaction effect between wheat cultivars (Shandaweel-1, Misr-2 and Misr-1) and the herbicides Pallas, Onostar followed by Traxsos showed the least dry weight of total annual weeds and gave the highest wheat grain yield followed Atlantis and Broadway star. Planting wheat cultivar Shandaweel-1 and controlling weeds by hand weeding twice at 30 and 45 days, or by using herbicides Onostar followed by Traxsos produced the highest wheat grain yield followed by Atlantis, Pallas or Broadway star.
