A management study was designed to investigate the desirability of two management systems emphasizing (1) yield and (2) quality and a third system (3) aimed at achieving an acceptable level of both yield and quality. (These are hereafter referred to as the high yield, quality, and yield and quality systems, respectively.)
Two varieties, Burley 21 and Ky 10, were grown under the three management systems (outlined in Table 1) in 1/4 acre non-replicated plots at five locations in Kentucky in 1966 and at seven locations in 1967. A three-year or older sod was selected at each location. Phosphorus and potassium were applied in all systems at rates based on soil tests. Applications were sufficiently large so that these elements would not be limiting factors in plant growth
