Nutritional Requirements of Poa annua L.1

Pot experiments were conducted in the greenhouse to determine the nutritional requirements of Poa annua. Total top yield was greater for annual bluegrass grown in silt loam soil than in loamy sand. In loamy sand a large decrease in clippings, crowns, and roots was obtained at a pH of 4.5 compared to pH 6.5. Differences between pH levels were not significant in the silt loam soil. N, P, and K contributed most to top growth in the order mentioned. Results of this study indicate that annual bluegrass has the ability to grow better than Kentucky bluegrass, Poa pratensis L., at a low pH level in a silt loam soil.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
