RESUMO:

The objective of this work was to evaluate different techniques of direct seeding (in holes and the haul), as well as to identify the influence of litter transposition after sowing, to emergence and establishment of native species in ecological restoration work in a area of degraded springs in the municipality of Cáceres-MT. In the experiment presented here two direct sowing techniques (in holes and by broadcast) were analyzed in two different environments. (with and without litter transposition), using three species of native plants, (Jacaranda cuspidifolia Mart., Sterculia apetala (Jaqc.) H. Karst., Vochysya divergens Pohl.), in a factorial scheme (2x2) in a degraded spring area. Being four treatments: T1 direct seeding in holes, T2 direct seeding in holes with litter, T3 seeding direct seeding by broadcast and T4 direct seeding by broadcast with litter, with eight replications each. THE emergency, establishment were monitored for three months and had height, collar diameter and number of leaves for ten months. For the species S. apetala, the best treatment was T2, obtaining better values in all parameters analyzed in this experiment. For the species J. cuspidifolia T4 was more efficient for the percentage of emergency, establishment, emergency speed index, average emergency time, for the average height and diameter of the collar, number of leaves and survival rate, T3 proved to be more promising. For the species V. divergens the treatment that obtained the best values in all parameters analyzed in the experiment was T4. Large seeds have better germination and emergence rates in the field, using the sowing technique direct, when compared with small seeds, The litter transposed after sowing direct influence positively on emergence, establishment and provided plants with greater vigor at the end of the experiment. Showing to be a possibility to improve the chances emergence and establishment of species with small seeds, used in forest recovery. Thus, we consider that the use of litter transposition can be one of the efficient auxiliary methods in ecological restoration.
