Abstract

The objectives of this study were to determine the quantity and calorific value of biomass of the varieties investigated as well as the amount of nutrients in plowed biomass. Soybean varieties in the research were:“Tisa”, “Podravka”, Neoplanta”, “Ika” and “Vita”. Average yield of all examined soybean varieties was 3.06 t/ha. By using 80% soybean straw the best results showed variety Tisa with 48.97 GJ/ha or it is substitute for 1375.19 Nm3/ha of natural gas or 1194 t/ha of oil fuel. They are followed by Tisa, Neoplanta, Podravka, Ika and Vita. These are huge amounts of energy that can be used for soybean drying process and it can be used as energy source for other uses. The estimated fertilization value of harvest soybean leftovers are in the same level as fresh ow or horse manure. Namely, it represents 40% of fertilization value of composted farm manure.
