influence of climate factors and plant varieties on the hay technology (fibrous feed)

The present study was carried on the Research and Didactical Station Jucu located close to Someş River. The aim of the study is to determine the fuel consumption and productivity of aggregates (machineries) used in the conditions of the two levels of hay production technology. The experimental plot uses Festuca Arundinacea, while control, spontaneous vegetation (Dactilys glomerata 70%, Alopecurus pratensis 10% Festuca sp.6%, Trifolium repens 5%, other plants 9%). Grassland soil taken in study type is molded with a high coefficient of withering (16-19%) and a small capacity water output (8%). Chemical characteristics of soil samples shows us a good content in humus and good to very good in mobile potassium, being deficient in phosphorus mobile. The differences noted between the fuel consumptions for the two parcels is due to higher vegetable production of control plot which has also a running speed of different aggregates also influencing effective productivity.
