Abstract
Two field trials were conducted in 2018 and 2019 seasons at Mallawy Agric. Res., Station, El-Minia Governorate, Egypt, to study the effect of fifteen weed control treatments, (Maister power at 750, 500 and 250 cm3/fed alone, Maister power at 750, 500 and 250 cm3 /fed. tank mixed with Divest at 500 cm3 /fed. Equib at 1125, 750 and 375 cm3 /fed. alone, Equib at 1125,750 and 375 cm3/fed tank mixed with Divest at 500 cm3/fed. alone as well as hand hoeing twice and unweeded (check) on weeds, yield and its components of three maize hybrids (SC 168, SC 131 and TC 324). The results indicated that: Maize hybridsexhibited a significant effect on dry weight of grassy and total annual weeds in both seasons. SC 168 surpassed the other tested hybrids in all maize grain yield and its components. Except 100- grain weight. Weed control treatments decreased significantly the dry weight of grassy, broad-leaved and total annual weeds on both seasons, and had a significant effect on maize yield and its component in both seasons. Grassy, broad leaved and total annual weeds differed significantly in first season only. Maize ear diameter, no. rows/ear in both seasons and ear length in the second season only were significantly affected by the interaction between maize hybrids and weed control treatments. Grain yield ardab/fed. were positively and highly significantly correlated with maize yield and its components and negatively and highly significantly correlated with weed characters in both seasons.
