Our investigations show that the peat from Bosansko Grahovo (Bosnia and Herzegovina) is a convenient substratum for the cultivation of the above mentioned species provided adequate nutrition is given. PK-fertilization of Finus halepensis Mill, has shown a significantly higher effect than N-fertilization. After the aplication of dead coniferous needles to the substratum the influence of nitrogen on the growth was not significant. It was found out that N-fertilization for the cultivation of Robinia pseudoacacia L. and Spartium juncem L. on the peat from Bosansko Grahovo should be avoided. N-fertilizer reduced the number and quality of sedlings. Root nodules of Rhizoblum sp. were poorly developed by N-treatment. Simbiotic nitrogen fixation must have been reduced. This is a well-known effect of N-fertilization The application of CaC03 resulted in the growth reduction and a slight cholorosis of Robinia pseudoacacia L. Adding confierous needles considerably reduced the negative effect of CaCOj Fh — 608 (6x7,5 cm) papertpot containers are not convenient for the production of Robinia pseudoacacia L. seedlings. |
