The choice of a mixed structure of fodder crops, including annual and perennial species, becomes a necessity for Romanian farmers due to the droughty periods recorded during the vegetation period of fodder plants. The choice of some species with good adaptability at drought and high forage yields in such climatic conditions has no less importance. Moreover, the application of a proper fertilization influences both the reaction of species at climatic conditions and the level of obtained yields. This study aims to find species/crops and fertilization levels which can provide good forage yields in drought conditions. In this respect six crops represented by two mixtures as oat + peas (control - C1) and triticale + pea (C2), respectively by four pure crops as rape (C3), millet (C4), sorghum x Sudan grass hybrid (C5) and sweet sorghum (C6), on three levels of fertilization (N0P0 kg∙ha-1 - F1, N60P70 kg∙ha-1 - F2 and N120P70 kg∙ha-1 - F3), were studied. The study was undertaken in 2011 when the rainfall level during sowing-harvesting period (March-July months) was with 362.65 mm lower than in 2010 and with 184 mm lower than in 2009, respectively. Sweet sorghum and sorghum x Sudan grass hybrid fertilized with N60P70 kg∙ha-1 and N120P70 kg∙ha-1 doses were revealed with significant high dry matter yield among the studied crops and experimental variants (crop x fertilization). Among the mixtures of annual grasses and legumes taken into the study and which can be used in pig farming within experimental area, in a descending order, considering the obtained yields, the following variants can be recommended for farmers: triticale + peas fertilized with N120P70 kg∙ha-1 dose and unfertilized oat + peas.
