Abstract: Zero tillage and minimum till systems often result in greater stratification of physical, chemical and biological soil environment which differs greatly from that of conventional tillage.Hence keeping in view of the importance of zero tillage in conservation of soil health and with an aim to increase the production and productivity of finger millet under rice fallow conditions, this experiment was conducted to standardize the fertilizer management technology of finger millet under zero tillage.The experiment was conducted for three years from 2017-18 to 2019-20 during the Rabi season at Agricultural Research Station, Vizianagaram.Results showed that grain yield of finger millet was found to be significantly higher in the treatment received with 150% RDF (3571 kg ha -1 ) along with spraying of 1% KNO 3 twice at flower initiation stage and 15 days after flowering and it was on par with 125% RDF + spraying of 1% KNO 3 (3309 kg ha -1 ).Spraying of 1% KNO 3 twice at flower initiation stage and 15 days after flowering along with basal application of NPK helped in further increase in grain yield, compared to their respective treatments of NPK alone to the tune of 2.9% in 50% RDF, 5.8% at 75% RDF, 5.6% at 100% RDF, 5.7% at 125% RDF and 4.11% at 150% RDF respectively.The highest net returns and B:C ratio were recorded in 150% RDF+1% KNO3 foliar spray(2.53)which is very closely followed by 125% RDF+ 1% KNO3 foliar spray(2.42).Similarly soil available nitrogen, phosphorus and potassium were significantly high in 150% RDF+1% KNO3 foliar spray, and it was on par with 150% RDF and 125% RDF+1% KNO3 foliar spray.From this study, 125% RDF+1% KNO3 foliar spray was found to be the best nutrient management in finger millet grown under zero tillage conditions in rice fallow situation.
