Interactions of mulch and farm yard manure on yield attributes and yield of turmeric

A field experiment was conducted during 2007-08 and 2008-09 at Ludhiana to study the interactions of mulch and farm yard manure on yield attributes and yield of turmeric (Curcuma longa L.). Increase in the mulch levels from no mulch to 6.25 t/ ha and 6.25 to 9.38 t/ ha, there Was significant increase in mother, primary and secondary rhizome weight per plant and fresh rhizome yield during both the years. Increase in farm yard manure levels from 30 to 45 t/ha also increased significantly yield attributes (mother, primary and secondary rhizome weight per plant) and fresh rhizome yield during 2007-08 and 2008-09. Application of 9.38 t/ha mulch with 45 t/ha farm yard manure resulted in maximum mother, primary and secondary rhizome weight per plant and fresh rhizome yield during both the years of crop growth. Increase in farm yard manure and mulch levels increased yield attributes and fresh rhizomes yield due to more availability of nutrients and water.
