A field experiment was conducted during 2007–08 and 2008–09 at Ludhiana to study the effect of different cultural practices on weeds, yield and economy of turmeric (Curcuma longa L.). Mother rhizome planting material resulted in significantly less weed population than primary and secondary finger planting material. The plant height, tillers/plant, leaves/plant, number of rhizomes/plant and mother, primary and secondary rhizome yields were also significantly more with mother rhizome planting material as compared to primary and secondary finger planting material. Increase in the paddy straw mulch levels from no mulch to 6.25 t/ha and then from 6.25 to 9.38 t/ha significantly decreased weed population and resulted in better growth parameters, yield attributes and mother, primary and secondary rhizome yield. On the other hand increase in farmyard manure levels from 30 to 45 t/ha significantly increased weed population, but growth parameters, yield attributes and mother, primary and secondary rhizome yield increased due to increased availability of nutrients and water. Oil and curcumin content in turmeric was not significantly affected by the planting materials, mulch or FYM application. However, oil and curcumin yield was higher when mother rhizomes were used and also increased with mulching and FYM application during both the years. Mother rhizome planting material, 9.38 t/ha mulch and 45 t/ha FYM resulted in the highest net return and benefit: cost (B: C) ratio.
