ABSTRACT

The aim of the research paper is to evaluate the biomass accumulation potential of fast growing basket willow (Salix viminalis L.) cultivated for energy purposes on human planted plantation. The experiment was realized in two four-years periods (1996 – 1999; 2000 – 2003) of the agri-ecological conditions analysis for growing of different basket willow varieties at the Experimental Base of Slovak University of Agriculture in Nitra (Slovak Republic). The influence of these factors on dry matter yields of basket willow was reviewing: variety (ORM, RAPP, ULV), stand organization (arrangement A – double rows = 0.5 m x 0.75 m or 1.25 m; arrangement B = 0.5 m x 0.75 m) and growing seasons (1996 – 1999; 2000 – 2003). There can be determined an order between different basket willow varieties for cultivation in the warm south Slovakia conditions: 1.ULV: 56.47 t.ha-1; e.g. average of dry matter yield accumulated after two four-yearscultivation cycles; 2. ORM: 43.37 t.ha-1; 3. RAPP: 25.10 t.ha-1. From the standorganization point of view better results were achieved in the arrangement B (44.63 t.ha-1) than in arrangement A (38.94 t.ha-1). These are results from two four-years cycles ofbasket willow cultivation (plantation was planted in 1996). Next part of contribution deals with the creation of agrometeorological models of phytomass production, which can be used for benchmark foreboding of phytomass yields by the occurrence of temperatures and rainfall. It showed that the yield of phytomass, which were established by agrometeorological model showed an average probability of 86%. In the approximately 40% of years was probability of appearance amount of yield phytomass provided with an accuracy of 96%. Finally, we can conclude that the simple mathematical – statistical model provides a solid ability for prediction of Salix viminalis phytomass.
