Abstract
Seeding Rate and Nitrogen Application Effects on Spring Oat and Triticale Forage
Highlights
Spring oat and triticale are important forage crops in dryland and limited irrigation crop production systems in western Kansas
Previous research in western Kansas showed that growing spring forages in place of fallow reduced soil erosion and increased fallow precipitation use efficiency compared to summer fallow, and increased profitability compared to fallow in years with average to above average rainfall
Seeding rate had no effect on forage dry matter (DM) or nutritive value in both oat and triticale
Summary
Spring oat and triticale are important forage crops in dryland and limited irrigation crop production systems in western Kansas. Despite the great potential of spring forages, information on seeding rate and nitrogen fertilizer recommendations are limited. These management practices can affect forage productivity and nutritive value. In dryland crop production systems in western Kansas, cool-season forages are usually planted in the spring into winter wheat (Triticum aestivum L.) or a summer crop (corn or grain sorghum) stubble. Lower spring temperatures and N immobilization from the previous crop residue often limit early-season N availability for oat or triticale forage. It is imperative that site-specific N fertilizer research is conducted to fine-tune N fertilizer rates for these cool-season forages to improve yields and environmental quality
