Herbage production and nutrient content are affected by light interception soil fertility. The objective of this study was to assess the effects artificial shade fertilization on herbage production, growth characteristics, grass species Dactylis glomerata Festuca ovina, legume Trifolium subterraneum Medicago lupulina. Each plant placed under three shading treatments 90% (heavy shade), 50% (moderate shade) 0% (control). Fertilization (225 kg/ha N, 450 P, 225 K) applied half pots every treatment. Reduced intensity (90% shading) significantly lowered from 18% for F. ovina 48% D. decreased root:shoot (R/S) ratio all but moderate reduction (50%) did not affect R/S grasses M. lupulina, while it resulted in an increase T. 10.5%. increased 25% average, crude protein concentration subterraneum. 16% 59% ameliorated its content. Among tested species, demonstrated highest tolerance could be incorporated into silvopastoral systems Mediterranean region.
