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

摘要

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 ofrows/ear,number ofgrains/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 biomass 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.
