Abstract

Abstract Five spring wheat ( Triticum aestivum L.) varieties were fertilized with five N treatments in 1969 and two N treatments in 1970 near Belgrade, Mont. The varieties were chosen to represent short, medium, and tall height levels, and each was evaluated for agronomic and quality response. Grain yields of normal ‘Centana’ and medium Centana were similar, even though medium Centana was 25% shorter and the straw yield was 17% less. There was no variety‐by‐fertilizer interaction for yield, indicating that the short and medium height types did not respond any better to N fertilizer than the standard height types. Short Centana had significantly less of its protein translocated from plant to grain than tall or medium Centana. Gain protein percentages decreased as the grainstraw ratio increased, suggesting that the amount of top growth is important in extracting nutrients from the soil. Nitrogen fertilizer significantly increased grain protein percentages, and there was a corresponding increase in loaf volume and grain and texture scores. Baking absorption and mixing time decreased slightly with increasing amounts of N. Water use was similar for the five varieties and increased with increasing rates of N.
