| Abstract/Contents: | "Four bluegrass varieties and four bluegrass selections (Pacific Northwest) were planted in June of 1956 on Palouse silt loam soil. In this establishment year, only maintenance treatments were made to keep the grass growing vigorously. Clipping treatments of 1 inch and 1/2 inch and nitrogen treatments of 8 lbs. per 1,000 square feet and 2.5 lbs. of nitrogen per 1,000 square feet were divided into 4 equal monthly applications for the season and were initiated on split-split plots on May 1, 1957. The total split plot (2 by 8 feet) was cut at weekly intervals for 20 weeks, ending September 25. Clippings were dried and weighed as one basis for assessing turf response. The same treatments were repeated for as many weeks in 1958. Root samples from plugs 4 inches in diameter by 8 inches deep were taken on October 5, in 1957 and 1958, washed, dried and weighed as another basis for assessing turf response. Some of the results are as follows: (1) 1-inch cut + 8 lbs. N yielded the most clippings (1/2 inch + 8 lbs. = second high yield); (2) 1/2-inch cut + 2.5 lbs. N yielded the least clippings; (3) 1-inch cut + 2.5 lbs. N yielded the most roots (1/2 inch + 2.5 lbs. = second high root yield); and (4) 1/2-inch cut + 8 lbs. N yielded the least roots. These data indicate that root and shoot production are inversely affected by nitrogen and cutting height. Nitrogen, here, appears to cause the greatest effect and clipping height is secondary." |
