Abstract: Rice (Oryza sativa) is one of the most important food grain crops and used as second most important cereal crop in the world after wheat crop. The majority of the rice-wheat areas are in the Indo-Gangetic plain which run from the North to East across the northern India. Among the different diseases of rice, Brown spot disease is also an important calprit for low yield of the crop. This field experiment was performed at Kharif during the year of 2015-16 at Agri Farm, IAS, BHU, Varanasi to assess the effect of cow urine spray on the suppression of Brown spot of rice. The experiment was conducted with three replication under the split plot design where Fertility levels (60% RDF, 80% RDF and 100% RDF) were kept under main plots and Cow urine spray (Control, 50%, 75% and 100% concentrations) were kept under subplots. The recommended dose of fertilizer (RDF) was 120-60-60-25 Kg N-P2O5-K2O-ZnSO4 ha-1. The varying fertility levels were unable to show the suppression of the brown spot disease whereas the varying concentrations of cow urine spray showed positive impact on that disease suppression. The 100% cow urine spray was able to minimize the brown spot score where as the control treatment exhibited maximum disease score. So, Cow urine as a bio-fungicide is able to reduce Brown spot infestation.
