Abstract:

The field experiment entitled “Effect of weed management practices on yield and economics of linseed (Linum usitatissimum L.) in Vertisols of Chhattisgarh” was carried out during rabi season of 2020-21; at the Instructional Cum Research Farm, DKS College of Agriculture and Research Station, Bhatapara. The experiment was laid out in Randomized Block Design with 3 replication and 12 treatments viz.T1 - Weedy check, T2 -1 hand weeding at 20 DAS, T3- 1 hand hoeing at 20 DAS + 1 hand weeding at 40 DAS, T4 - pendimethalin @ 0.90 kg a.i.ha-1(PE), T5 -pendimethalin @ 0.90 kg a.i. ha-1 (PE)+1 hand weeding at 40 DAS, T6- pendimethalin @ 0.90 kg a.i. ha-1 (PE)+ imazathypr @ 100g a.i. ha-1(PoE), T7- pendimethalin @ 0.90 kg a.i. ha-1(PE) + isoproturon @ 1kg a.i. ha-1 (PoE), T8- pendimethalin @ 0.90 kg a.i. ha-1 (PE) + metsulfuron methyl @ 4g a.i. ha-1 (PoE), T9 - metsulfuron methyl @ 4g a.i. ha-1 (PoE), T10- imazathypr @ 100 g a.i. ha-1(PoE), T11 - isoproturon @ 1 kg a.i. ha-1 (PoE) and T12 - weed free. Linseed variety Indira alsi-32 (RLC-81) was sown on 09th November, 2020 at 30 × 10 cm spacing using 20 kg seed ha-1 with recommended level of nutrients 60, 30 and 30 kg N, P2O5 & K2O ha-1 respectively. Crop was harvested on 24th February, 2021. The result showed that the weed free (T8) recorded highest yield, which was statistically at par with 1 hand hoeing at 20 DAS + 1hand weeding at 40 DAS (T3). Highest benefit: cost ratio was recorded in pendimethalin @ 0.90 kg a.i. ha-1 (PE) + metsulfuron methyl @ 4g a.i. ha-1 (PoE) (T8) followed by metsulfuron methyl @ 4g a.i. ha-1 (PoE) (T9). Weedy check (T1) was the most inferior treatment which recorded 875 kg ha-1 and 1326 kg ha-1 grain and straw yield respectively.
