RESUMO

Two experiments were carried out with four different fodder tree legumes Leucaena leucocephala, Leucaena pallida, Sesbania sesban and Codariocalyx gyroicks. The main objective of the first experiment was to determinate the energy tragment distribution trom the seed, to produce shoot and root system using seed laboratory facilities. The second experiment was carried out in a greenhouse using 5 kg soil containers two levels of phosphorus, three levels of lime, as well as two levels of molybdenium,in a factorial scheme arranged in a complete randomized blocks design with four replications. The objective was to select the most adequate germoplasms adapted to acids soils and to poor phosphorus content. The results obtained in the first experiment indicated that Codariocalyx gyroicks has allocated more energy to produce root system. In the second experiment the species that showed better adaptation to the acid soils and poor in phosphorus, were Codaricaly gyroicks ( 2nd harvest), and Sesbania sesban (1st harvest), being at one best species nodulation. On the other hand, the plants with the highest protein content were Leucaena leucocephala and Leucaena pallida
