Abstract:
A field experiment was conducted to find out suitable sowing time, optimum seed rate, and right cultivar of oat for Telangana at Agricultural Research Institute, Professor Jayashankar Telangana State Agricultural University Rajendranagar Hyderabad. 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 oat varieties (JHO 822 and Kent). The experiment was conducted in a split-plot design and replicated thrice in a sandy loam soil. Two-year (2016-17 & 2017-18) pooled data analysis results revealed that seed yield was significantly (p=0.05) higher with the crop sown during the first fortnight of November (25.3 q/ha) followed by the second fortnight of October (21.4 q/ha). Whereas seed yield was 17.0 q/ha and 18.7 q/ha for October first fortnight sown and November second fortnight sown oat respectively. Statistically no significant difference was observed among the two seed rates for number of tillers per meter row length, number of grains per spike, test eight, and also grain yield. Varieties are also followed the similar trend with that of seed rate for the entire seed yield parameters and seed yield. All the interaction effects were found to be non significant. The best sowing window was found to be from the second fortnight of October to the first fortnight of November for obtaining higher oat grain yield in Telangana_.
