Nutrient Uptake and Quality of Finger Millet as Influenced by Organic Nutrient Management

Abstract— A field experiment was conducted during rabi2023-24 at Agricultural College Farm, Naira, Acharya N.G. Ranga Agricultural University, Andhra Pradesh. The experiment was laid out in a split-plot design and replicated thrice. The finger millet variety Indravathi (CFMV 1) was tested in the present experiment. Application of 100% RDF (60:30:30 NPK kg ha-1) recorded significantly higher nutrient uptake by plant, straw and grain over the rest of the nutrient treatments. Among the organic nutrient foliar sprays, foliar application of Panchagavya spraying twice @ 3% at tillering and flowering stages was found to be the best over other three organic foliar sprays tried under organic finger millet cultivation. Application of 100% RDN through Poultry manure (M3) recorded significantly higher soil microbial population i.e., total count of bacteria, fungi and actinomycetes, which was however comparable with application of 50% RDF (NPK kg ha-1) + 50% RDN through Poultry manure (M2). Among the foliar sprays, application of Liquid Azospirillum+ PSB+ KRB+ [email protected] ha-1biofertilizer consortium by root dipping at transplanting (S1) recorded. Significantly the highest protein content in grain was recorded with the application of 100% RDF (60:30:30 NPK kg ha-1)(M1), which was superior over the rest of treatments applied and the lowest protein content was recorded with application of 100% RDN through Poultry manure (M3).
