Other claims from this paper (19)
- Intervention effect Increasing N levels from 15 to 60 kg/fed significantly increased the number and dry weight of barley weeds.
- Intervention effect Application of 60 kg N/fed gave the highest number and dry weight of weeds.
- Intervention effect Metosulam at 0.04 L/fed reduced dry weight of broadleaved weeds by 92.83 to 95.46 percent after 60 and 90 DFS.
- Intervention effect Metosulam at 0.04 L/fed failed to completely control narrow-leaved weeds.
- Intervention effect Clodinafop-propargyl at 140 g/fed reduced dry weight of narrow-leaf weeds by 94.34 to 94.85 percent after 60 and 90 DFS.
- Intervention effect Isoproturon with diflufinican came first for controlling total weeds, statistically level with isoproturon alone.
- Intervention effect Isoproturon with diflufinican lowered number and dry weight of total weeds relative to unweeded plots 60 days after sowing.
- Intervention effect Isoproturon with diflufinican lowered number and dry weight of total weeds relative to unweeded plots 90 days after sowing.
- Intervention effect Isoproturon with diflufinican herbicide gave 66.3 percent more grain yield than the weedy check.
- Intervention effect Herbicide treatments and hand weeding significantly increased growth, yield and yield components of barley.
- Intervention effect Herbicide treatments and hand weeding significantly increased chemical composition of barley grain.
- Intervention effect Isoproturon with diflufinican was superior for plant height, spike length and grains number per spike.
- Intervention effect Isoproturon with diflufinican was superior for grains weight, spikes number, straw and grain yields.
- Intervention effect Isoproturon with diflufinican was superior for grain protein and total carbohydrate percentage.
- Association The interaction of N levels and weed management had a significant effect on total weed dry weight, spike number and grain weight per spike.
- Association The interaction of N levels and weed management had a significant effect on grain and straw yields.
- Intervention effect Isoproturon with diflufinican gave the lowest total dry weight of weeds after 60 and 90 DFS when 15 kg N/fed was added.
- Intervention effect 60 kg N/fed gave the maximum number of spikes per square metre and weight of grain per spike when isoproturon with diflufinican was applied.
- Intervention effect 60 kg N/fed gave the maximum grain and straw yields when isoproturon with diflufinican was applied.
