Abstract

A field experiment was conducted under coastal Odisha conditions. The experiment was laid out in a Randomized Block Design with 9 treatments replicated thrice. The treatments consisting of T1: 75% RDF + 25% N through Vermicompost; T2: 75% RDF + 25% N through Vermicompost + FYM; T3:75% RDF + 25% N through Vermicompost + FYM +Bio fertilizers; T4:50% RDF + 50% N through Vermicompost; T5:50% RDF + 50% N through Vermicompost + FYM; T6: 50% RDF + 50% N through Vermicompost + FYM +Bio fertilizers; T7: 100% N through Vermicompost.; T8: 100% N through Vermicompost + FYM; T9:100% N through Vermicompost + FYM +Bio fertilizers. The result of the study revealed that maximum total soluble solids (11.420Brix and 10.93 0Brix), Vitamin-C (199.60 mg/100g and 189.08 mg/100g), total phenol contents (113.05 mg GAE/100g fresh weight and 88.21 mg GAE/100g fresh weight), total flavonoid contents (38.64 mg QE/100g fresh weight and 34.14 mg QE/100g fresh weight), FRAP value (21.61 mM Fe(II)/100g fresh weight and 18.39 mM Fe(II)/100g fresh weight), scavenging activity (62.03 % and 58.65 %) were observed with the plants treated with 50% RDF +50% N through Vermicompost + FYM +Bio fertilizer in both mrig and hasth bahar. The incorporation of nutrients through organic and inorganic resources leads to enhanced quality attributes of guava in Coconut Cropping System.
