A field experiment was conducted during 2018 and 2019 at Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur, Rajasthan, to study the effect of crop-management practices on weed dynamics, yield and economics of soybean [Glycine max (L.) Merr.]. The experiment was laid out in randomized block design with 4 replications, comprising 5 treatments of different crop-management practices, viz. conservation organic, conservation chemical, conventional chemical, organic management + conventional tillage and package of practices. The results showed that, conservation chemical was found the most effective in controlling total weeds (5.5 m2 ) and reduction of dry-matter accumulation by weeds (24.8 kg/ha) as compared to the package of practices, conventional chemical, conservation organic and organic management + conventional tillage at 30 days after sowing (DAS). However, at 45 DAS, conservation organic was the most effective in controlling total weeds (5.9 m2 ) and reduction of dry-matter accumulation by weeds (35.9 kg/ha) as compared to organic management + conventional tillage, conservation chemical, package of practices and conventional chemical on pooled basis. Significantly higher seed (1,850 kg/ha), haulm (2,824 kg/ha), net returns (`48,913/ha) and benefit : cost ratio (3.2) of soybean were recorded under conservation chemical followed by package and practices and conventional chemical.

“…This might be because of the ineffectiveness of pendimethalin fb bispyribac‐sodium in suppressing this weed in the field and also due to higher diversity of weed species in unweeded control resulting in less dominance of E. alba . Poor control of E. alba with pendimethalin was also reported earlier by Panda et al (2015). With the application of herbicides, susceptible species are killed and selection pressure is increased for the species which are not susceptible to applied herbicides (Duary, 2008).…”

The above‐ground community dynamics of weeds represent the soil weed seedbank in an agro‐ecosystem. Hence, understanding the seedbank will offer an idea for future weed management tactics. We aimed to determine the density of weed seedbank and emergence of major weeds in direct seeded rice (DSR) (Oryza sativa L.)—mustard (Brassica campestris L. var. yellow sarson) cropping sequence under varied tillage and herbicide combinations. The present study on weed seedbank was conducted using seedling emergence method after collecting the soils at the harvest of mustard at the completion of 2 years field experimentation. The experiment was conducted in split‐plot design with two tillage practices [zero tillage (ZT) and conventional tillage (CT)] in main plot and eight weed management practices in DSR [oxadiargyl followed by (fb) bispyribac‐sodium, penoxsulam + cyhalofop‐butyl, oxadiargyl fb penoxsulam + cyhalofop‐butyl, fenoxaprop‐p‐ethyl + ethoxysulfuron, oxadiargyl fb fenoxaprop‐p‐ethyl + ethoxysulfuron, pendimethalin fb bispyribac‐sodium, unweeded control, and weed free check] as subplot. The carry‐over effect of tillage and weed management practices were recorded in mustard crop. Seed emergence study revealed that ZT reduced the emergence of grassy weeds (by 13.7%) and total weed emergence (19.5%) in comparison to the CT (p < 0.05). However, emergence of broadleaf weeds was 24.5% higher in ZT than in CT. The higher infestation was recorded for Ludwigia parviflora (Jacq.) Raven under penoxsulam + cyhalofop‐butyl, fenoxaprop‐p‐ethyl + ethoxysulfuron, Cyperus iria (L.) under fenoxaprop‐p‐ethyl + ethoxysulfuron, and Eleusine indica (L.) Gaertn. under pendimethalin fb bispyribac‐sodium, oxadiargyl fb bispyribac‐sodium. Sole application of post‐emergence (POE) herbicide decreased the total weed emergence by 22.2%–28.1% than unweeded control (p < 0.05). Whereas, sequential application of PRE + POE herbicides decreased the total weed emergence by 32.8%–36.9% than unweeded control (p < 0.05). Notably, sedge weeds such as Cyperus iria (L.) and Fimbristylis miliacea (L.) Vahl were lower in ZT than in CT under herbicide treated plots (by 66.6%–84.3%) than unweeded control. Thus, ZT with oxadiargyl 90 g a.i. ha−1 fb fenoxaprop‐p‐ethyl + ethoxysulfuron (90 + 15 g a.i. ha−1) as tank‐mix can be effectively used to lower the weed seedbank density vis‐à‐vis managing complex weed flora in DSR and rice‐mustard cropping sequence.

“…Two hand weeding resulted in good aeration and nutrient availability to crop growth throughout vital crop growth phase due to increased availability of water, space, nutrients to the crop plant and reduce crop-weed competition during the critical crop growth stage. Panda et al (2015) and Kumar et al (2018) were also found the Similar results.…”

Background: Weeds are major factor that leads to increase crop-weed competition and adversely effects of on growth, quality and yield of urdbean during kharif season. In urdbean the critical period for crop weed competition was the first 25-30 days; yields can be reduced by 50-90%, if weeds were not controlled during this period. As a result, successful weed management strategies to achieve increased growth and yield. Due to the ease, lower cost, timeliness and success controlling weeds, the progressive transformation of agriculture involving intensive use of herbicides has gained traction in recent years. Methods: During kharif season 2019, a field experiment was undertaken at the Agricultural Research Station of Ummedganj, Kota, comprising ten weed management strategies, laid out in a randomised complete block design with three replications. Result: Two hand weedings at 20 and 40 DAS recorded significantly lower weeds dry matter, higher weed control efficacy, ultimately culminating in improved yield attributes and yield, compared to weedy check. This treatment was at par with pendimethalin 30% EC @ 1 kg a.i. ha-1 fb propaquizafop 2.5% w w-1 @ 33.3 g a.i. ha-1 + imazethapyr 3.75% w w-1 (pre mix) ME @ 50 g a.i. ha-1 at 20 DAS resulting in significantly higher pods plant-1 (13.67), seeds pod-1 (6.33), test weight (28.47 g), grain (827 kg ha-1), straw (1393 kg ha-1), biological (2221 kg ha-1) and harvest index (37.26%) of urdbean over the other chemical based treatment.
