Influenţa soiului şi a sistemului de cultură asupra acumulării zilnice de substanţă uscată (kg/ha/zi) la trifoiul roşu pentru furaj

Abstract

For a good and complet variety caracterisation we must to take in consideration also the rate of vegetal production in daily accumulation, at every haymaking and for all vegetation period.The quantity of vegetal production wich is accumulating every day, at each haymaking and for all vegetation crop period is influenced by climatic conditions (rainfall, temperature), by plants growth phases (at the start of plants growth or during the plants growth), by the technology wich was applied (fertilization, crop system – single crop or mixt crop with perene gramineum), but in the same time is influenced also by the genetics elements of Trifolium pratense varieties.In this experimental three years I registered the daily rate of dry matter accumulation (kg/ha/day) at four fooder red clover varieties: Roxana, Select, Dacia-Tetra and Flora), each of them was studied in three different crop systems (single crop, mixt crop with Dactilys glomerata, and mixt crop with Lolium multiflorum).
