Description

Production of three mixtures was tested in order to determine the production functions in different environments of sown swards which were either grazed or cut and grazed. The experiment took place in six italian localities between 41 and46 degress North. Mixtures were formed by two legumes (Trifolium repens + Lotus corniculatus) and by one of three different grasses (Festuca arundinacea , Dactylis glomerata, Phleum pratense) of different earliness. Production of each locality was registered weekly and related as cumulative data to following pedoclimatic parameters: thermal summation, wilting point, field capacity, ETP, thermohydrological coefficient (L ETP x L temperatures). Six multilinear regression functions were obtained with a satisfactory predictive value for production in marginal areas of a large part of italian territory.
