“…Anjum et al (2007) stated that increasing densities of Trianthema portulacastrum weed up to 10 plants m -2 significantly reduced the seed cotton yield and lint yield. Seed cotton yield was significantly reduced under untreated check (Mahar et al, 2007).…”

“…According to Anjum et al (2007), increasing densities of Trianthema portulacastrum weed up to 10 plants m -2 significantly reduced the number of sympodial branches plant -1 , number of bolls plant -1 and seed cotton weight boll -1 . The number of sympodial branches plant -1 and productive bolls plant -1 were significantly reduced under untreated check (Mahar et al, 2007). The square and boll number of cotton (Mushtaq and Cheema, 2008) were significantly affected by weed competition.…”

“…Increasing densities of Trianthema portulacastrum weed up to 10 plants m -2 significantly reduced the LAI and crop growth rate (CGR) of cotton (Anjum et al, 2007). According to Mahar et al (2007), plant height of cotton was significantly reduced under untreated check. Mushtaq and Cheema (2008) concluded that plant establishment, plant height and biomass of cotton were significantly affected by the weed growth and competition.…”

“…Nagalakshmi et al (2006) noticed that hand weeding twice showed significant effect in reducing weeds and also increased the yield. Mahar et al (2007) reported that hand weeding for full season in cotton significantly reduced the weed density (92.4 per cent) and increased the plant height, sympodial branches plant -1 , productive bolls plant -1 and seed cotton yield. Verma et al (2009) reported that hand weeding twice recorded 87.55 per cent W CE and one weeding followed by earthing up treatment recorded maximum of 93.88 per cent W CE.…”

Cotton is one of the most important commercial crops in India. Cotton growth is very slow in the initial stages of its life cycle and row spacing is wider which provides ample space for the growth of different categories of weeds and thus become a source of competition for water as well as nutrients, thereby impeding its growth. Weeds are major constraints that reduce the crop yields since they compete with crop for the nutrients, moisture, light and space. The integration of different weed management practices would be a viable option for broad spectrum weed control and enhancement of cotton productivity. Thus, weed management has several aspects such as physical, mechanical, cultural, chemical and integrated weed management methods. A brief review of research accomplishment made at various places on different fields related to this investigation is reviewed in this paper.

“…More than 3,000 species of weeds are prevalent in world agriculture, and 1,800 of them cause enormous economic damage, of which more than 200 species are in strong competition with major agricultural crops [1][2][3][4][5]. As a result of a combination of agro-technical and chemical control measures against them, high results are being achieved in the United States, Brazil, Australia, China, India, Pakistan, Germany, South Korea, Russia and a number of other countries [2,4,[6][7][8][9][10].…”

Effects of continuous application of Samurai and Zellek Super herbicides on cotton fields against weeds in the conditions of Uzbekistan

et al. 2021

This scientific article provides data on the effectiveness of successive application of herbicides against annual and perennial weeds in cotton fields on arable lands plowed with simple and two-sided plows. When the herbicide Samurai (1.5 l/ha) is applied separately, the annual weeds are effectively lost (86.8-90.2%), and have a weak effect on perennials. When Zellek Super (1.0 l/ha) herbicide is used separately, it has a weak effect on annuals (24.0-32.0%), effectively reducing weeds. Both perennial weeds (90.5-93.0%) and perennial weeds are effective when applied in series with Samurai (1.5 l/ha) and Zellek Super (1.0 l/ha) herbicides 88.9 -93.3% loss. Cotton yield will increase by 1.8-5.4 q/ha compared to the control option. Consecutive application of Samurai (1.5 l/ha) and Samurai (1.5 l/ha) and Zellek Super (1.0 l/ha) herbicides against annual and perennial weeds is recommended.

Today, in the world agriculture, especially cotton growing sphere plays an important role in the national economy. In the cultivation of cotton one of the main problems in the fields is weeds. When estimating the damage caused by weeds to cotton fields, it accounted for 75 bln. USD. This scientific article presents data on the effectiveness of pre-and post-application of herbicides against weeds in the areas where the tillage was done with double-toothed plow in the fall before preparing beds in the fine-fiber cotton fields under typical gray soils condition. Effective eradication of annual and perennial weeds (86.8-90.2%) was observed, when a single herbicide Ankosar (3.0, 4.0, 5.0 l/ha) was applied (information of 2017-2019). When the herbicides Step 500 (4.0 l/ha) and Ankosar (4.0 l/ha) were applied consecutively, the effect on annual weeds was noted (90.5-93.0%). Perennial weeds were reduced by 88.9-93.3% when the abovementioned preparations are applied one after another. Cotton yield will increase by 1.8-5.4 c/ha compared to the control variant. It is recommended to apply the herbicides consecutively in the order Ankosar (4.0 l/ha), Step 500 (4 l/ha) and Ankosar (4.0 l/ha) against annual and perennial weeds.
