Description

Perennial legumes are an important source of fodder in high­land regions of Yugoslavia. Three legume spp. were chosen for this trial: Trifolium pratense, T. repens and Lotus corniculatus (components of highland spontaneous ecosystems). Posibilities of growing them as pure stands were investigated when treated with mineral N, or seed inoculation. The effec­tiveness of inoculation depends on soil caracteristics: the best results were obtained on acid soils (Misistin and Siljnikova, 1968). The spontaneous types of Rhizobium trifolii and R. lotus exist in most types of highland soils in Yugoslavia (Vojinovic et al., 1978). The effect of inoculation is the most expressive in the two first years of application (Vojinovic et al., 1967). Number of authors (Patil et al., 1973; Dorosinski et al., 1981) indicated that DM increases significantly with inoculation and NPK fertilisation (where mineral N is not higher than 120 kg/ha). Content of CP rises with increased level of N ferti­lisation regardless of inoculation (Habish et al., 1974). The objective of this study was to indicate what kind of treatment was necessary for successful production of the three legumes investigated in highland region.
