Post-emergence herbicides efficacy for weed management in kharif maize (Zea mays)
The escalating labour prices have significantly increased the production cost of kharif maize in India. To addressthis, a field experiment was conducted (2017) to evaluate the efficacy of post-emergence herbicide in kharif maize(Zea mays L.) at ICAR-Indian Institute of Maize Research, Pusa Campus, N...

| 520 | |a The escalating labour prices have significantly increased the production cost of kharif maize in India. To addressthis, a field experiment was conducted (2017) to evaluate the efficacy of post-emergence herbicide in kharif maize(Zea mays L.) at ICAR-Indian Institute of Maize Research, Pusa Campus, New Delhi. The tank-mix post-emergenceherbicide application, viz. tembotrione (120 g/ha) or topramezone (25.2 g/ha) at 15 DAS with 75% atrazine (750 g/ha) or as a sequential application at 25 DAS after pre-emergence (PE) 75% atrazine gave significant weed control inkharif maize by reducing density and dry weight. Significantly higher weed-control efficiency, weed-control index,herbicide efficiency index and lower weed persistence index were found in weed-free check, which was at par withPE atrazine (1000 g/ha) followed by hand weeding at 25 DAS and the post-emergence herbicide application oftembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix with 75% atrazine dose as early post-emergence at 15DAS or as the sequential application of these combinations. Significantly lowest weed index was observed in thesequential application of tembotrione/topramezone at 25 DAS after 75% atrazine dose as PE while the highest weedindex (49.3) with alone halosulfuron application. It was concluded that the application of post-emergence herbicide,viz. tembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix at 15 DAS with 75% dose of atrazine (750 g/ha)or as a sequential application at 25 DAS after 75% atrazine as PE found promising for better weed control and grainyield in kharif maize. | ||

The tank-mix post-emergenceherbicide application, viz. tembotrione (120 g/ha) or topramezone (25.2 g/ha) at 15 DAS with 75% atrazine (750 g/ha) or as a sequential application at 25 DAS after pre-emergence (PE) 75% atrazine gave significant weed control inkharif maize by reducing density and dry weight. Significantly higher weed-control efficiency, weed-control index,herbicide efficiency index and lower weed persistence index were found in weed-free check, which was at par withPE atrazine (1000 g/ha) followed by hand weeding at 25 DAS and the post-emergence herbicide application oftembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix with 75% atrazine dose as early post-emergence at 15DAS or as the sequential application of these combinations. Significantly lowest weed index was observed in thesequential application of tembotrione/topramezone at 25 DAS after 75% atrazine dose as PE while the highest weedindex (49.3) with alone halosulfuron application. It was concluded that the application of post-emergence herbicide,viz. tembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix at 15 DAS with 75% dose of atrazine (750 g/ha)or as a sequential application at 25 DAS after 75% atrazine as PE found promising for better weed control and grainyield in kharif maize.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Herbicide-efficiency index</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Maize</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Weed-control efficiency/index</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Weed dynamics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Weedpersistence index</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Agriculture</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">S</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">S L JAT</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">C M PARIHAR</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">A K SINGH</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">V POONIYA</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">RAJ SINGH</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">The Indian Journal of Agricultural Sciences</subfield><subfield code="d">Indian Council of Agricultural Research, 2023</subfield><subfield code="g">91(2021), 11</subfield><subfield code="w">(DE-627)DOAJ000156906</subfield><subfield code="x">23943319</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:91</subfield><subfield code="g">year:2021</subfield><subfield code="g">number:11</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.56093/ijas.v91i11.118530</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doaj.org/article/d424c92c0da142df8923bf7eef3db5fa</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://epubs.icar.org.in/index.php/IJAgS/article/view/118530</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">https://doaj.org/toc/0019-5022</subfield><subfield code="y">Journal toc</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">https://doaj.org/toc/2394-3319</subfield><subfield code="y">Journal toc</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_DOAJ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">91</subfield><subfield code="j">2021</subfield><subfield code="e">11</subfield></datafield></record></collection>

Post-emergence herbicides efficacy for weed management in kharif maize (Zea mays) |
| abstract |
The escalating labour prices have significantly increased the production cost of kharif maize in India. To addressthis, a field experiment was conducted (2017) to evaluate the efficacy of post-emergence herbicide in kharif maize(Zea mays L.) at ICAR-Indian Institute of Maize Research, Pusa Campus, New Delhi. The tank-mix post-emergenceherbicide application, viz. tembotrione (120 g/ha) or topramezone (25.2 g/ha) at 15 DAS with 75% atrazine (750 g/ha) or as a sequential application at 25 DAS after pre-emergence (PE) 75% atrazine gave significant weed control inkharif maize by reducing density and dry weight. Significantly higher weed-control efficiency, weed-control index,herbicide efficiency index and lower weed persistence index were found in weed-free check, which was at par withPE atrazine (1000 g/ha) followed by hand weeding at 25 DAS and the post-emergence herbicide application oftembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix with 75% atrazine dose as early post-emergence at 15DAS or as the sequential application of these combinations. Significantly lowest weed index was observed in thesequential application of tembotrione/topramezone at 25 DAS after 75% atrazine dose as PE while the highest weedindex (49.3) with alone halosulfuron application. It was concluded that the application of post-emergence herbicide,viz. tembotrione (120 g/ha) /topramezone (25.2 g/ha) as tank-mix at 15 DAS with 75% dose of atrazine (750 g/ha)or as a sequential application at 25 DAS after 75% atrazine as PE found promising for better weed control and grainyield in kharif maize. |
