Abstract: A field investigation was conducted to study the effect of graded levels of fertilizers on growth and yield of finger millet under rice fallow condition. The nutrient management in rice fallow finger millet conducted during Rabi 2018-19 at Agricultural Research Station, Vizianagaram. Results showed that grain yield of finger millet was found to be significantly higher (35.85 q/ha) in the treatment received with 150% RDF over 100% RDF (28.81q/ha) and was on par with 125% RDF (31.11q/ha). Spraying of 1% KNO3 at flower initiation stage 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 5.2% in 50% RDF, 11.68% at 75% RDF, 10.0% at 100% RDF, 8.58% at 125% RDF and 4.12% at 150% RDF respectively compared to their alone application of graded levels of RDF. 150% RDF+1% KNO3 foliar spray recorded significantly higher grain yield; However, it was on par with 150% RDF and 125% RDF+ 1% KNO3 foliar spray. The highest net returns and B:C ratio were recorded in 150% RDF+1% KNO3 foliar spray followed by 150% RDF similarly soil available nitrogen, phosphorus and potassium were significantly high in 150% RDF+1% KNO3 foliar spray, however, 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 rice fallow situation.
