Abstract:
Twelve weed control treatments viz. metribuzin at 0.70 kg/ha followed by (fb) hand weeding at 45 and 75 days after planting (DAP), metribuzin at 0.70 kg/ha fb straw mulch at 10 t/ha fb hand weeding at 75 DAP, pendimethalin at 1 kg/ha fb hand weeding at 45 and 75 DAP, pendimethalin at 1 kg/ha fb straw mulch at 10 t/ha fb hand weeding at 75 DAP, atrazine at 0.75 kg/ha fb hand weeding at 45 and 75 DAP, atrazine at 0.75 kg/ha fb straw mulch at 10 t/ha fb hand weeding at 75 days, oxyfluorfen at 0.30 kg/ha fb hand weeding at 45 and 75 DAP, glyphosate at 1.23 kg/ha fb hand weeding at 45 and 75 DAP, glyphosate at 1.85 kg/ha fb hand weeding at 45 and 75 DAP, hand weeding at 25, 45 and 75 DAP, weed control with organic practice (mulch) and unweeded check were evaluated for weed control in turmeric on silty clay loam soil at Palampur during 2017. Total weed count increased with the age of the crop with highest values recorded at 120 DAP after which the total weed count declined. Contrary to this maximum dry weight of weeds was recorded at 150 DAP which declined at later stage. All the weed control treatments significantly reduced the total weed count and dry weight of weeds as compared to the weedy check. Amongst different herbicide treatments application of metribuzin @ 0.70 kg/ha fb straw mulch fb hand weeding resulted in significantly lowest weed count at all stages of observation as well as at harvest though this treatment was at par with metribuzin @ 0.70 kg/ha fb two hand Weedings. These two treatments along with application of atrazine @ 0.75 kg/ha fb two hand weedings and atrazine @ 0.75 kg/ha fb straw mulch fb one hand weeding resulted in significantly lower dry matter accumulation by weeds as compared to other herbicide treatments. Highest fresh and cured rhizome yield was recorded with the use of metribuzin fb straw mulch fb hand weeding at 75 DAP though this treatment was at par hand weeding and all other herbicide treatments except the treatment in which oxyfluorfen was used. The present study indicates the need of including mulch in any effective weed management strategy for turmeric.
