| Tartalmi kivonat: | Application of the fertilizers contributes to the enlargement of the biomass quantity and thus any effort is justified for the fodder plants where is aimed to obtain fodder volume (COJOCARIU L. ET AL., 2010). The goal of this paper is to find a functional dependence of the dry matter production for the Alopecurus pratensis fodder based on different amounts of fertilizer, in order to obtain the technical optimum and also depending on the cultivation technology that is applied. As biological material we used the variety Alpha of meadow foxtail, seeded in autumn at 12,5 cm and 25 cm distances between rows, by scattering method. In the paper there are presented the results obtained in the species Alopecurus pratensis, cultivated at different distances between rows and fertilized with different doses of nitrogen. The largest yields of dry matter were recorded in all variants for the maximal dose of nitrogen (240 kg ha). However, the technical maximum of dry matter was recorded as following: 8219 kg ha-1 for an amount of 214,65 kg ha-1 nitrogen and for 12,5 cm distance between rows; 8091,8 kg ha-1 for an amount of 216,25 kg ha-1 nitrogen and for 25 cm distance between rows, and 8746 kg ha-1 for an amount of 208,29 kg ha-1 nitrogen and for sowing by scattering. |
