ABSTRACT

The present study entitled “effect of weed control on weeds, grain yield and its components of maize (Zea mays L.) cv. Single cross-10 was carried out at the Agricultural and Experiments Research Station at Giza, Faculty of Agriculture, Cairo University, Egypt. The experiment was conducted in the summer 2017 and was repeated in 2018 on the same piece of land to conform previous findings. The experiment design was Randomized Complete Block design (RCBD) having three replications. Six treatments include atrazine (1.0 kg/ha), glyphosate (0.8 kg/ha). atrazine + glyphosate, one hand hoeing after three  weeks, hand hoeing twice  after three and five weeks from sowing and weedy chick as control were used. Results indicated that glyphosate was found superior to atrazine for all studied characters. Moreover,  lower  weed dry matter accumulation and higher weed control % as well as higher values of ear characters ( ear length, ear diameter, grain weight/ear and shilling %) and grain yield per unit area  were recorded in tank mix application of atrazine + glyphosate followed by hand hoeing twice.

Keywords: Maize, yield, yield components and weed control.
