Abstract/Contents:"The effect of returning turfgrass clippings on mown turf, in terms of the value of clippings as a nitrogen source as well as management interactions on grass growth, has not been well examined. The objective of the present research was to study the impact of N rate and weather during the growing season on the effect of returned clippings and on efficiency of returned clippings. The experiment was carried out between 2004 and 2008. Over a five-year period, a field experiment was conducted on a sward of Festuca rubra rubra and Poa pratensis. Measured experimental factors included two clipping treatments, with clippings removed or clippings returned, as well as seven fertilizer rates. The swards' dry matter yield was significantly influenced by clippings treatment, applied N rate, year, and these interactions. Returning turfgrass clippings provide significant positive effects on the dry matter yield only when plants are fertilized with N. Without N fertilization, the effect was negative or absent. Returned clippings impact (RCLI) increased with N rate up to 213 kg N ha-1 and then started to decrease. The annual effect of returned clippings at N level 240 kg ha-1 depended mainly on the amount of returned clippings in May and June, as well as on precipitation during May. The annual efficiency of returned clippings at the same N level was mostly associated with precipitation in May and June and the average temperatures in July. We conclude that the annual effect of returning grass clippings on mown turf is beneficial only with mineral fertilizer. Also, if the moisture condition is a limiting factor to the decomposition of clippings then the moisture conditions must be improved with the irrigation."
