Excerpt from Interrelationships of Nitrogen, Phosphorus, and Seasonal Precipitation in the Production of Bromegrass-Crested Wheatgrass HayThe response to nitrogen by bromegrass and crested wheatgrass was marked by earlier - 6 to 10 days - initiation of spring growth, by darker color, and by increased vegetative growth. Potential seed production, as indicated by the amount of heading, also improved with nitrogen fertilization. Head development was observed to be 10 percent for no fertilization and 31 percent for 160 pounds of nitro~ gen in a relatively dry year By contrast, the comparable observations in a wet year (1953) were 38 percent and 80 percent, respectively.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
