COMPARATIVE EFFICIENCY OF NEW HERBICIDES FOR WEED CONTROL ON QUALITY YIELD AND ITS COMPONENT IN MAIZE (ZEA MAYS)

A field experiment was carried out at the Experimental Farm of Sakha Agricultural Research Station at Kafr El-Sheikh Governorate, Egypt during 2018 and 2019 summer seasons to evaluate the effect of weed control treatments on the productivity and quality of maize plants. The treatments were arranged in a Randomized Complete Block Design with four replications. Weeds were controlled by all treatments compared with untreated check; however, hand weeding twice was not superior to herbicide treatments. Among the herbicidal treatments, Sonic + Maister power (504+600) cm3/ha was proved to be better in controlling weeds, increasing ear length, number of rows/ear, number of grains/row, 100-grain weight in the two seasons but ear diameter and ear grains weight in the first season. As protein percentage was increased with used Stomp extra and Maister power (1800+600) cm3/ha. Application of weed control treatments resulted in less weed bio-mass and greater maize yield. It was concluded that the use of herbicides, especially Sonic + Maister power (504+600) cm3 /ha in weed control, was suitable and enhanced maize yield as well as controlled the associated weeds.
