Abstract

Two field experiments were conducted during two successive summer seasons of 2018 and 2019 cotton crop (Gossypium barbadense L.) Giza 94 was planted. Eigh treatments + control were evaluated to demonstrate the effect of herbicides on the density of weeds and the morphological characteristics of weeds and cotton. Moreover, all weed control significantly decreased weeds parameters and increased yield components in both seasons. Also, gave ahighly significant increase in seed cotton yield (Kantar/Fadden). The highest values were obtained with stomp ®+ hand howing (45 DAP) and hand hoeing twice ( 30, 45 DAP) during two seasons (12.32a, 11.62a) and (11.9 a, 10.9 ab ). From obtainingresults the highest effect on fresh and dry weight weeds decreased with the stomp ®+ hand howing (45 DAP) and hand howingtwice (30, 45 DAP). These practices gave the highest reduction in weeds density and increased cotton.

Highlights

Cotton (Gossypium barbadense L.) is the most important cash crop in Egypt and the world but it is a source of many elements of daily use
Most of the broad leave and grassy weeds that found in the experimental field physalisperuviana, ammaniaegyptica,corchorusolitorius, xanthium strumarium, and Dinebraretroflexa were effected by all treatments during season 2018 and 2019 Efficacy of Herbicides on the Fresh and Dry Weight of Weeds: The results obtained in Tables 2 and 3 significantly reduced the weed populations after using herbicides during thetwo seasons of 2018 and 2019
During season 2018, fresh and dry weight for physalisperuviana and ammaniaaegyptica were calculated after 50 and 70 days of planting to determine the effect of herbicide

Summary

Introduction

Cotton (Gossypium barbadense L.) is the most important cash crop in Egypt and the world but it is a source of many elements of daily use. During seeason 2018, the fresh weight of grassy weed was recorded whereas, the obtained results clear that the highest value for xanthium wasestablished by stomp® + hand howing (62.75 e and 215 e ) after 50 and 70 days respectively.
