| Abstract | ||||
| At the Experimental Farm at Itay EL-Baroud Agricultural Research Station, Beherah Governorate, Egypt, field tests were carried out in the summers of 2015 and 2016 to assess the impact of three pre-emergence herbicides (acetochlor 84% EC (Harness), metribuzin 70% WG (Marrin El-Nasser) and pendimethalin 45.5%CS (Stomp Extra) and four post-emergence herbicides (foramsulfuron 2.25% OD (Equip), fluroxypyr 20 %EC (Starane), sulcotrione15% SL (Prestige) and thifensulfuron methyl + nicosulfuron 82.5% WG (Doramex Plus), in addition to the unweeded control, which reduces the biomass of fresh and dry weeds (gmm-2) of grassy, broadleaved, and total weeds in maize fields, and hand hoeing twice at 21 and 35 days after sowing (DAS).. Results showed that all the herbicides used significant reduction in weed biomass at 60 (DAS) but these herbicidal gave low control of grassy weed biomasses compared hand hoeing (twice). The highest reduction of weed biomass was obtained from hand hoeing twice (21 and 35), (Equip), (Starane) and (Stomp Extra) in both season, respectively compared to the control. Results showed that 100 grain (gm) weight rose with every weed control treatment, weight of ear (cob) and grain yield. When compared the harvest index percentage and biological yield to other treatments, hand hoeing twice, Equip, and Starane increase maize yield and yield components in both seasons. In addition, harvest index percentage and biological yield were compared to the unweeded control. When compared to other treatments, hand hoeing twice, Equip, and Starane increased maize yield and yield components. | ||||
