Characterization of cow urine for antimicrobial properties and plant growth promoter in rice (Oryza sativa L.)


Pawan Tirkey and Diptimayee Dash

A field experiment was conducted at Agricultural Research field, IGKV, Raipur, Chhattisgarh, during kharif 2023 to know the effect of various levels of RDF and cow urine application on yield of irrigated paddy (Oryza sativa L.) (Var: CG Devbhog) in clay loam soil. There were ten treatments laid out in Randomized Complete Block Design with three replications. Grain yield and straw yield were significantly higher (45.4 q/ha and 57.8 q/ha respectively), with application of 75% RDF + cow urine 30% twice (60 & 75 DAT) Which was on par with the application of 75% RDF + cow urine 20% twice (60 & 75 DAT) and 100% RDF (80:50:30 kg NPK/ha). The number of IAA producing bacteria that was successfully purified was 04 isolates. All isolates except FU2 were quantitatively measured in IAA producing using Salkowski reagent; concentration of IAA were ranged from 0.274 - 0.389 ppm. Characterization of cow urine was carried out to know the antifungal activity against fungal pathogens (Fusarium oxysporum). The extent of growth of test fungi in plates poisoned with cow urine was lesser when compared with the control plates. When the three concentrations of cow urine were compared, maximum growth suppression was observed in Fusarium oxysporum (53.33%) at 30% concentration of cow urine followed by 20% and 10%. Cow urine has antifungal activities and the inhibitory activity can be used in the control of fungi. The beneficial effect of cow urine on rice was also evaluated enhancing the grain yield.
