To study the efficacy of Azospirillum in organic and integrated nutrient management with farmyard manure (FYM) and graded levels of nitrogenous fertilizer on turmeric, an experiment was undertaken at Uttar Banga Krishi Viswavidyalaya, Pundibari, during 2008-09, 2009-10 and 2010-11. The experiment was laid out in randomized block design with three replications. The results revealed that application of 75% recommended inorganic nitrogen with Azospirillum at 5kg/ha and FYM at 15 t/ha gave the highest yield of 26.29 t/ha as against 22.96 t/ha in the control of recommended dose of fertilizers at the rate of 80:80:120 kg N, P2O5 and K2O per hectare. It was followed by the combined application of 50% recommended inorganic nitrogen with Azospirillum at 5 kg/ha and FYM at 15 t/ha with a yield of 25.8 t/ha and then 100% recommended in organic nitrogen with Azospirillum at 5kg/ha and FYM at 15 t/ha with a yield of 25.81 t/ha. The lowest yield of 18.36 t/ha was recorded in the treatment of sole application of FYM at 15 t/ha. The lowest dry recovery of 25.6% and curcumin content of 4.95% were recorded in control treatment with the application of only recommended dose fertilizers while the highest dry recovery of 26.87% was recorded with integrated nutrient management with application of 75% recommended inorganic nitrogen with Azospirillum at 5kg/ha and FYM at 15 t/ha and curcumin content of 5.11% was recorded in organic nutrient management with Azospirillum at 5 kg/ha and FYM at 30 t/ha.
