The study was conducted at Technical Institute of Cereals (ITGC- Setif) during the years 2014-2018 for understanding the effect of weed treatment in direct seeding on cereal yield, soil and seeds quality. Two horizons were considered: horizon one (0 less than H1 less than 20 cm) and horizon two (H2 less than 20 cm) and four herbicide doses were applied: D1 =1080g ha-1, D2= 900g ha-1, D3= 720 g ha-1 and D4= 540 g ha-1. The yield results depended on the herbicide doses applied before seeding. The highest yield responded to the highest dose of herbicide applied (1080g ha-1). Study indicated that glyphosate reached soil during weed treatment and transferred in deep soil layer and to harvested seeds. Half-live values (DT50) of glyphosate found under field conditions were high.

“…Keeping in view the economic and marginal analysis the application of HC 2 in stubble retention was the best, which might be attributed to less cost for land preparation in this treatment. Pendimethalin being a preemergence herbicide proved less efficient in controlling early season weeds under stubble retention, which indicate the poor efficacy of pre-emergence herbicides in ZT systems (Singh et al 2015). Bispyribac sodium being an early post emergence proved efficient in controlling early season weeds and provide DSR a good condition to grow and enhanced yield under stubble retention methods.…”

“…Stubbles present in these plots might have been hindered with the effective application and action of pendimethalin herbicide. As Singh et al (2015) described that effectiveness of pre-emergence herbicides is reduced in ZT systems due to the interception of herbicides. However, HC 2 application in stubble retention condition proved the best regarding kernel yield (Fig.…”

To ascertain the influence of wheat stubble management options and chemical weed control methods on weed growth and productivity of dry direct-seeded fine rice, a two years' field study was undertaken at the Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan in 2013 and 2014. Different wheat stubble management methods, viz., incorporation, burning and retention were executed during seed-bed preparation. While, herbicide treatments comprised of a weed check, weed free, pendimethalin followed by tank mixture of fenoxaprop p-ethyl+ethoxysulfuron ethyl, and bispyribac sodium followed by tank mixture of fenoxaprop p-ethyl+ethoxysulfuron ethyl. Results revealed that weed control efficacy of both herbicide treatments ranged from 84 to 94%. Herbicide treatments significantly reduced weed density (88-90%) and dry weight (86-88%), while improved the rice growth attributes compared with weed check. Application of bispyribac sodium followed by tank mixture of fenoxaprop p-ethyl+ethoxysulfuron ethyl in stubble retention recorded 226 and 273% increase in kernel yield over weedy check in 2013 and 2014, respectively. In stubble incorporation, pendimethalin followed by tank mixture of fenoxaprop p-ethyl+ethoxysulfuron ethyl was more effective in increasing (256-293%) rice yields over weedy check. Among different treatment combinations, the maximum net benefits (1 397.49-1 472.22 USD ha-1), net returns (636-700 USD ha-1), benefit cost ratio (1.77-1.83) and marginal rate of return (2 187-2 330%) were recorded with the application of bispyribac sodium followed by fenoxaprop p-ethyl+ethoxysulfuron ethyl in stubble retention. In crux, application of bispyribac sodium followed by tank mixture of fenoxaprop p-ethyl+ethoxysulfuron ethyl in stubble retention is efficient approach to control weeds, and get maximum rice productivity and net economic returns under dry seeded system.

“…More weed population in the second growing season, can be explained due to the favourable environmental conditions and higher rainfall. More weeds can also be supported by the lack of competitiveness and increase in weeds population due to each passing year of aerobic rice [25]. and was smiliar to its lower rate 150 and 120 g ha -1 in 2015.…”

Florpyrauxifen benzyl + cyhalofop butyl is a new combination herbicide product which has proven to control wide range of weed flora. A two year study was planned in the wet and dry seasons of 2015-16 and 2016-17 to evaluate effective dosage of early post-emergence combination herbicide product florpyrauxifen benzyl + cyhalofop butyl (120; 150 and 180 g ha-1) to manage weeds in aerobic rice and study the residual effect on succeeding maize crop. The results revealed that Barnyard grass (Echinochloa crusgalli) followed by Dinebra retroflexa (viper grass) dominated among the weed flora. The combination product florpyrauxifen benzyl + cyhalofop Butyl 180 g ha-1 contributed to significantly lower density and dry biomass accumulation by grass and broadleaf weeds as compared to weedy check; however its efficacy was poor on sedges at 60 days after sowing (DAS). Highest weed control efficiency was recorded by florpyrauxifen benzyl + cyhalofop butyl 180 g ha-1. The highest yield (4100 and 3420 kg ha-1) was in plots treated with florpyrauxifen benzyl + cyhalofop butyl at 180 g ha-1 and the lowest yield was in florpyrauxifen benzyl 31.25 g ha-1 (3280 and 2870 kg ha-1) followed by bispyribac sodium 25 g ha-1 (3320 and 2940 kg ha-1) in 2015 and 2016, respectively. Weed infestation decreased the rice yield by nearly about 69% in 2015 and 72% in 2016. A strong negative relationship between rice yield and weed biomass was seen which explained 87 and 91% variation in grain yield at 30 and 60 DAS. Combination product florpyrauxifen benzyl + cyhalofop butyl at all rates did not have any residual toxic effect on succeeding maize. Based on the findings, it can be concluded that aerobic rice weeds can be controlled by applying early post-emergence application of combination product florpyrauxifen benzyl + cyhalofop butyl 150 to 180 g ha-1 without any residual toxicity.
