Growth, Yields and Economics of Cumin (Cuminum Cyminum L) Production as Affected by Weed Management Practices

An experiment was conducted rabi season of 2008-2009 to find economically viable method of weed control for cumin. Results revealed that highest yield attributes and yield of cumin was recorded with post emergence application of Oxadiargyl 50 g ha-1 20 DAS + HW, being statistically at par with rest of the treatments except weedy check and post emergence application of glyphosphate @ 0.5 kg /ha. The seed yield of cumin in weedy check was only 75 kg /ha which was too low compared to weed free ( 605 kg /ha). Thus ,weed cause great loss to seed yield of cumin. The highest net return (Rs.41081 /ha) and BCR (2.17) was recorded with application of oxadiargyl 50 g /ha at 20 DAS which was higher over rest of the treatments. Thus, it can be inferred that application of Oxadiargyl 50 g ha-1at 7 DAS or 20 DAS + HW is best method of weed control for realizing higher yield.
