The weibull distribution to describe aboveground biomass of Lolium multiflorum Lam., in relation to rate of nitrogen application Agrociencia

Abstract Characterization of forage biomass in pasture land is complicated by the temporal and spatial variability that result from variation in vegetation patch sizes. These factors along with topography, water location and distribution of fertilizer result in non-uniform grass. The aim of the study was to evaluate the use of the three-parameter Weibull distribution to describe aerial dry matter (DM) production in the first harvest of a mixture of three Italian ryegrass (Lolium multiflorum Lam.) cultivars (the tetraploid ‘Jivet’ and ‘Barspirit’, and the diploid ’Barprisma’) in Asturias (N Spain). The trial was established in a randomized complete block design with three blocks of 100 m2 (20 m x 5 m) and a fertilizer treatment with three levels (0, 40 and...
