Abstract
A field experiment was conducted for two consecutive years to study the Influence of Integrated nutrient management practices on soil NPK nutrient balance under organic cultivation of chickpea (Cicer arietinum L.) grown in vertisol of northern dry zone of Karnataka, at Agricultural Research Station, Annigeri, UAS, Dharwad, Karnataka during Rabi season of 2009-2010 and 2010-2011. The experiment was laid out in RCBD with three replications. There were 18 treatment combinations consisting of four different organic manures in combination viz., farmyard manure (FYM), vermi compost (VC), glyricidia leaf manure (GLM), enriched compost EC, neem cake (NC) and four different liquid manures viz., panchagavya, biodigester, cow urine and vermiwash with two control treatments RDF and absolute control (water spray). Soil nutrient balances were worked for major nutrients (NPK) taking the initial soil status, nutrient addition, crop uptake and nutrient left in the soil after harvest. The maximum gain of NPK nutrients in soil over initial recorded with the treatment EC 1/3rd + VC 1/3rd + GLM 1/3rd equivalent to 100% RDN + panchagavya @ 3 % spray at flower initiation and 15 days after flowering (DAF) during both the years.
