Growth, yields and economics of cumin (Cuminum cyminum L.) production as affected by weed management practices

Abstract

An experiment was conducted at S.D. Agricultural University, Sardarkrushinagar during rabi season of 20082009 to find economically viable method of weed control for cumin. Results revealed that at 30 DAS response of weed control method was not noticed significant on plant height but at 60 DAS and harvest, besides weed free treatment ,application of Oxadiargyl 50 g ha-1 20 DAS + HW, exhibited the highest plant height being at par with all treatments except weedy check and application of Glyphosate @ 0.5 kg /ha. Similarly, besides weed free treatments the 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 highest net return (Rs.41081 /ha) and BCR (2.17) was recorded with application of Oxadiargyl 50 g /ha at 20 DAS which were higher over rest of the treatments. Thus, it can be inferred that application of Oxadiargyl 50 g ha-1at 7DAS or 20 DAS + HW is best method of weed control for realizing higher yield
