Weed Dynamics in Greengram as Influenced by Mulching and Weed Management Practices under Eight Year Old Custard Apple Plantation in Agri-horticultural System

Effect of Herbicides on Growth, Yield and Economics of Urdbean (Vigna mungo L.)

“…Same treatments was also recorded the highest weed control efficiency with the lowest weed index. Similar results was reported by Verma et al [8,9]. "However, two hand weeding at 20 and 40 DAS (weed free) was found more effective than the herbicides, due to slow pace of growth of first flush of weeds, 20 days after sowing thereafter the emergence of new flushes of weeds could not attain full growth under the shade of crop plants" [5,8,9].…”

“…The outcome of different weed control treatments was found significant. The number of branches/plants, pod length, grains/pod and 1000 grain weight was recorded significantly maximum under the treatment T 7 (Pendimethalin 1000 g/ha (Pre-em) followed by Imazethapyr 100 g/ha at 20 DAS) in comparison to alone application of Pendimethalin 1000 g/ha (Pre-em), Imazethapyr 100 g/ha (at 20 DAS), Propaquizafop 100 g/ha (20 DAS), Fomesafen 250 g/ha (20 DAS) respectively", [5,8,9] and "it was statistically at par with Fomesafen 210 g/ha + propaquizafop 65 g/ha (20 DAS). Higher yield attributes under these treatments may be due to lesser crop-weed competition, which gave better environment for crop growth and development of crop.…”

“…"Highest plant height and crop dry matter was recorded with Pendimethalin 1000 g/ha (Pre-em) followed by Imazethapyr 100 g/ha (at 20 DAS) in comparison to alone application of Pendimethalin 1000 g/ha (Pre-em), Imazethapyr 100 g/ha (at 20 DAS), Propaquizafop 100 g/ha (20 DAS), Fomesafen 250 g/ha (20 DAS), respectively and it was statistically at par with Fomesafen 210 g/ha + propaquizafop 65 g/ha (20 DAS) (Table 2) while, the statistically lowest plant height and crop dry matter was recorded under weedy check (T1). The reason for higher values on growth parameter can be discussed in the light of fact that crop under this treatment had comparatively less weed competition" [5,8,9]. "The reduction in weed competition in blackgram by the use of herbicides or hand weeding not only favoured the crop growth with abundant availability of moisture, nutrients, light and space, but also reduced over all weed interference, facilitating vigorous growth and development of crop plants" [8,9].…”

Crop Establishment Methods and Weed Management Practices Affects Crop Growth, Yield, Nutrients Uptake and Weed Dynamics in Wheat

“…However, ZT/CT without residue showed negative WCE in both the years, indicating that there may be problem of perennial and annual weeds in without residue application treatments as compared to ZT with residue and CT with residue treatments. The residue mulch suppressed the germination and growth of weeds and resulted in higher WCE (Verma et al, 2016). WCE was significantly highest with application of mesosulfuron+iodosulfuron followed by clodinafop+metsulfuron, metsulfuron fb one hand weeding at 45 DAS and mesosulfuron fb one hand weeding at 45 DAS, respectively.…”
