Abstract/Contents:"The performance of three strains of Poa pratensis; Merion, Fylking and Nugget were examined together with two varieties of Lolium perenne; S23 and Barenza in sand culture in a glasshouse. The aim of the experiment was to identify the implications on turf quality of variations in cutting height and nitrogen nutrition. Cutting heights used were 1.25 cms, 2.5 cms and 7.5 cms. The nitrogen levels in the nutrient solutions were 14 ppm, 56 ppm and 140 ppm. Other essential nutrients were maintained constant and were non-limiting. Weights of clippings, yields of roots, and numbers of tillers and top weight (verdure) were used as indices of performance. Stolon production was recorded in Poa pratensis. It was found that whilst cutting height and nitrogen supply have overall effects on turfgrass performance, these aspects of management interact and should not be considered independently. Thus, whereas a general decrease in yields of clippings, roots, numbers of tillers, verdure and stolon production was recorded with decreasing height of cut, these parameters of growth varied markedly with nitrogen supply at each cutting height. It is concluded that for any defined combination of environmental factors, light, temperature and soil moisture and providing no other plant nutrient is limiting, clipping height determines the nitrogen response. In particular, within the range of cutting heights examined the lower the cutting height the lower the nitrogen required to produce maximum top-growth also the higher the cutting height the higher the nitrogen level required to avoid visual nitrogen deficiency. It was found for all grasses that the response of the roots to nitrogen supply differed considerably from growth response in the tops. Under nitrogen deficient conditions root systems may be very dense despite restriction in top-growth. Results are discussed from the physiological viewpoint and with regard to their implication for turfgrass management."
