Effect of Species and Land Preparation method on the Maintenance of Saplings on Eroded Lands in Frata Perimeter, in the First Year After Planting.

In order to establish the influence of species and land preparation method on the maintenance of saplings planted on degraded lands due to sheet erosion in Frata amelioration perimeter (Cluj county, Romania) we used black locust (Robinia pseudoacacia) and manna ash (Fraxinus ornus). The land preparation methods used were terraces and pits. We established the saplings maintenance degree in the first year after planting. To establish the influence of species and antierosional land preparation on the maintenance of saplings planted and which stroke roots, we placed two experiment (bifactorial). The significance of the differences between the tested variants was shown using Duncan (Tuckey) test of multiple comparisons, considering significant differences DS_5%. As compared to manna ash, the black locust provided the highest saplings maintenance degree, at an insignificant difference. Terracing, as antierosional land preparation provides the highest maintenance degree at an insignificant difference as compared to the pits, no matter the species involved. The variants which provided the highest maintenance degree were manna ash x wattle fence terraces and black locust x wattle fence terraces and the lowest maintenance degree was registered by the manna ash planted in pits.
