abstract
The present experiment entitled “foliar spray of cow urine on growth and yield of transplanted rice (Oryza sativa L.)” was conducted during Kharif season 2023 at Dau Kalyan Singh College of Agriculture and Research Station, Bhatapara (C.G). The experiment was laid out in Split Plot Design (SPD) with 16 treatments and three replications. The treatment consists of N₁ (Control), N₂ (100% RDF), N₃ (75% RDF) and N₄ (50% RDF) at Main Plot: Nutrient level treatment S₁ (10% at Tillering and Panicle Initiation Stage), S₂ (10% at Tillering and Panicle Initiation and Grain Filling Stage), S₃ (20% at Tillering and Panicle Initiation Stage) and S₄ (20% at Tillering and Panicle Initiation and Grain Filling Stage) at Sub Plot: Cow urine spray. The results showed that the 100% RDF (N₂) performed the best in terms of number of panicles hill^-1, no. of filled grains panicle^-1, no. of chaffy grains panicle^-1, test weight (g), grain yield (q ha^-1), straw yield (q ha^-1), this was followed closely by the treatment 75% RDF (N₃), the Control treatment (N₁) consistently gave the lowest values for all the parameters measured at Main Plot: Nutrient level. The results showed that the 20% at Tillering and Panicle Initiation and Grain Filling Stage (S₄) performed the best in terms of number of panicles hill^-1, no. of filled grains panicle^-1, no. of chaffy grains panicle^-1, test weight (g), grain yield (q ha^-1), straw yield (q ha^-1), this was at par with closely by the treatment 10% at Tillering and Panicle Initiation and Grain Filling Stage (S₂) and 20% at Tillering and Panicle Initiation Stage (S₃), the 10% at Tillering and Panicle Initiation Stage treatment (S₁) consistently gave the lowest values for all the parameters measured at Sub Plot: Cow urine spray. Overall, the study used to exploring the effects of different nutrient levels (100%, 75%, and 50% RDF) and cow urine spray timings (10% and 20% at various stages). Results showed that 100% RDF (N₂) significantly improved growth and yield parameters. Among the cow urine spray treatments, the 20% spray at Tillering and Panicle Initiation and Grain Filling Stage (S₄) produced the highest yield and growth, followed closely by other spray treatments, while the control treatment (N₁) had the lowest results.
