A field experiment was conducted to find out suitable sowing time, optimum seed rate, and right cultivar of fodder oat for Telangana. The treatments consisted of 16 combinations with four times of sowing (first fortnight of October, second fortnight of October, first fortnight of November, and second fortnight of November), two seed rates (80 and 100 kg/ha), and two fodder oat cultivars (JHO 822 and Kent). The experiment was conducted in a split-plot design and replicated thrice in sandy loam soil. Two-year (2016-17 & 2017-18) pooled data analysis results revealed that green fodder yield, dry matter yield, and crude protein yields recorded were significantly (p<0.05) higher with the crop sown during the first fortnight of November followed by the second fortnight of October. Plant height and tiller number per meter row length also responded similarly. No significant difference was observed among the two seed rates for plant height, the number of tillers/meter row, green, and dry fodder yields except crude protein where 100 kg/ha seed rate recorded higher crude protein yield than 80 kg/ha seed rate. Cultivars significantly differed in plant height and crude protein yield only. All the interaction effects were found to be non-significant. The best sowing window for obtaining higher fodder yield and quality of oat in Telangana was found to be from the second fortnight of October to the first fortnight of November.
