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.
