These <br /> <br />cultural practices are used in each clilllDtic zone judged suitable for <br />grain sorghum production. Fertility requirements, summarized in <br />Table 6.31 will vary in each climatic zone. <br /> <br />6.2.7 Oats/Oat Hay <br />Oat grain and oat hay production have steadily increased in Colorado <br /> <br />over the last 5 years. According to Colorado Agricultural <br /> <br />Statistics published by the Colorado Department of Agriculture, <br />Colorado ranked twenty-third in total oat production in 1984 with <br />1,887,000 bushels harvested from 29,000 acres with an average yield <br />of about 65.0 bushels per acre. Specific data to determine average <br />oat hay yields are not available from Colorado Agricultural <br /> <br />Statistics. <br /> <br />In Montezuma and La Plata counties in Southwest Colorado. a total of <br />84,000 bushels of oats was harvested from about 1,200 acres with an <br /> <br />a~erage yield of about 70 bushels per acre. Oats are best suited to <br /> <br />cooler climatic areas. Hot, dry weather prior to heading seriously <br /> <br />reduces yields by causing the plant to ripen prematurely with poorly <br />filled grain. Climatic conditions prevailing on the Ute Indian <br />Reservation lands were summarized in Section 4. These conditions <br />impact the suitability of oats to achieve economic yields in <br /> <br />6- 46 <br />
