Abstract
An experiment was carried out to evaluate the effect of planting density (12 500, 25 000 and 37 500 plants/ha) and nitrogen fertilization (100, 300 and 500 kg N/ha/year) on the yield and bromatological composition of Morus alba var. tigreada. The dry matter yield of the total (DMYTB) and edible biomass (DMYEB), and the yield of the leaves (DMYL) and the fresh stems (DMYFS) were measured during two years. The crude fiber (CF) and crude protein (CP) percentages were also calculated. There was interaction of the factors (p < 0,05) in the DMYFS; the highest values were obtained when the maximum planting density was combined with the three doses of N (0,37; 0,35 and 0,32 kg DM/plant), as well as when combining 25 000 plants/ha with 300 and 500 kg N/ha/year (0,27 and 0,34 kg DM/plant, respectively). In the variables DMYTB, DMYEB and DMYL there was no interaction of the studied factors. The highest values of total and edible biomass and leaves were reached with 37 500 plants (4,43; 2,37 and 2,03 kg DM/plant ) and the maximum dose of N (3,16;1,89 and 1,68 kg DM/plant). It is concluded that the best results regarding the yield of mulberry were obtained

It is concluded that the best results regarding the yield of mulberry were obtained with the density of 37 500 plants/ha; its combination with the lowest dose of N produced high yields of fresh stems, which constitutes an important component of the biomass consumed by livestock.
