Abstract An experiment was conducted on loamy sand soil of Instructional Farm, Department of Agronomy, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar (Gujarat) during the rabi season of 2011–12 to study the influence of weed control methods on yield, quality and economics in dill seed (Anethum graveolens L.) in randomized block design (RBD) with four replications and 10 weed control treatments comprising T1: Pendimethalin @ 0.5 kg/ha PE, T2: Pendimethalin @ 1.0 kg/ha PE, T3: Pendimethalin @ 0.5 kg/ha PE+one hand weeding after 30 DAS, T4: Oxadiargyl @ 50 g/ha PoE at 20 DAS, T5: Oxadiargyl @ 75 g/ha PoE at 20 DAS, T6: Pendimethalin @ 0.5 kg/ha PE+Oxadiargyl @ 50 g/ha PoE at 20 DAS, T7: Pendimethalin @ 0.5 kg/ha PE+Oxadiargyl @ 75 g/ha PoE at 20 DAS, T8: Weed free, T9: Weedy check and T10: Farmers' practice (One hand weeding+one interculturing at 30 DAS). Significantly maximum grain yield of 1294 kg/ha and stover yield of 2255 kg/ha were recorded in the treatment weed free. The treatment involving weed free resulted in significantly highest oil content of (3.95%) and oil yield (51.12 kg/ha). Treatment weed free secured maximum gross returns of Rs. 32356/ha. The lowest gross returns (Rs. 20963/ha) were recorded with treatment unweeded control. The highest net returns of Rs. 19309/ha and B: C ratio of 2.60 were recorded under treatment pendimethalin 0.5 kg/ha PE+oxadiargyl @ 75 g/ha PoE at 20 DAS. Treatment unweeded control registered the lowest net returns of Rs. 10618/ha and B: C ratio of 2.03.
