Weed Management in Maize System in New Alluvial Zone of West Bengal

Chemical weed management in maize using pre and post emergence herbicides

“…The reduction in weed competition in maize by the application of herbicides not only favored the crop plants with more availability of space, light, moisture and nutrients but also minimized weed interference, facilitating vigorous growth of crop plants. These results are found to be in close conformity with Biswas et al, (2018) [2] and Barua S. (2019) [1] .…”

“…It might be due to two fold action of this combination and sequential application that affected both grasses as well as broad leaf weeds. The greater effectiveness of Pendimethalin 1000 g a.i.ha -1 (PE) fb 2,4-D amine 1000 g a.i.ha -1 (PoE) has also been reported by Biswas et al (2018) [2] and Barua S. (2019) [1] , who observed least total weeds dry weight under these combination. Maximum weed index was observed in Weedy check, followed by Halosulfuron-methyl 90 g a.i.ha -1 (PoE), Tembotrione 120 g a.i.ha -1 (PoE) and Atrazine 1000 g a.i.ha -1 (PE) fb Halosulfuron-methyl 90 g a.i.ha -1 (PoE).…”

Effect of Sequential Application of Herbicides on Weed Density, Weed Dry Weight and Yield of Irrigated Maize

“…At 60 DAS, lowest weed density and dry weight were recorded in weed free condition (T 7 ) and was followed by the application of atrazine at 0.25 kg a.i ha -1 as PE at 3 DAS followed by tembotrione at 120 g a.i ha -1 as POE at 25 DAS (T 3 ) and was on par with application of pendimethalin at 1.0 kg a.i ha -1 as PE at 3 DAS followed by tembotrione at 120 g a.i ha -1 as POE at 25 DAS (T 4 ).Among the different herbicides, application of tembotrione as post emergence significantly reducing the grassy and nongrassy weeds by inhibits the 4hydroxyphenyl-pyruvatedioxygenase (4-HPPD) enzymes which causes lack of electron acceptor in photosynthesis. Similar findings are recorded by Sonali Biswas et al, (2018). Highest weed density and dry weight were observed in unweed check (T 8 ) (Fig.…”

Unexplored agronomic, socioeconomic and policy domains for sustainable cotton production on small landholdings: a systematic review

“…Intercropping, a practice of growing more than one crop simultaneously on the same piece of land is widely practiced by smallholder farmers to diversify food basis, and income and avoid risks of complete failure of one crop before attaining maturity (Reddy and Shaik, 2009;Biswas et al, 2018;Salama et al, 2022). Also, intercropping saves land resources by increasing its productivity, often measured by the land equivalent ratio and relative yield or net returns (Koraddi et al, 1991;Singh and Ahlawat, 2011;Vaghasia and Dobariya, 2019).…”

“…Cotton is a long-duration and widely spaced crop, occupying large land areas hence its sustainability on small land-holdings can be easily up-scaled through intercropping using compatible and early maturing crop species (Surendran et al, 2016;Kumar et al, 2017;Biswas et al, 2018;Lv et al, 2023). Surendran et al (2016) reported that the suitable intercrops with cotton plants could be those of grain legumes, including Phaseolus beans, cowpea (Vigna unguiculata (L.) Walp.…”
