Influence of Fertilizer Rate, Mower Type, and Thatch Control on Colonial Bentgrass Lawn Turf1
- C. R. Skogley
With rising cost of fertilizers and other turf maintenance products there is keen interest in finding less expensive methods of establishing and maintaining lawns. An improved cultivar of colonial bentgrass (Agrostis tenuis Sibth.), ‘Exeter’, was sown in the field in 1966 and a study including fertilization, mower type, and mechanical raking was initiated in 1968. Asplit-split plot design was used with mower type as the main block with one rotary and two types of reel mowers included. Subplot was mechanical raking including treatment in April or in September and no raking. Subsubplots were fertilizer treatments and included a 10-2.6-3.3 grade material to supply 0.5 kg N/are per treatment applied in April only, September only, April and September, or April, June, and September. Visual quality scores were taken most months during the growing season from 1970 through 1974.
Results showed that mowing with a rotary mower lessened turf quality, while there was no difference between a roller drive or a side-wheel drive reel mower. Mechanical raking for thatch control was not beneficial during the period of this study. Three seasonal applications of fertilizer provided slightly better quality turf while two applications provided much higher quality turf than one.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
