Potential and actual quantities of wheat straw that can be collected on family farm

Wheat is an important source of biomass, which the world is paying attention, due to the increasing exhaustion of non-renewable energy sources. Wheat takes part in the production of biofuels, where grain and straw are raw materials for liquid (ethanol) and solid biofuels (briquettes/pellets). Straw represents an important source of organic matter, has a significant impact on the biological, chemical and, physical properties of agricultural soils, and does not need to be considered as waste. The objective of this study was to determine the possibilities of collecting wheat straw from a certain area after harvest with machinery and equipment used on the family farm. The field experiment was conducted at one family farm in 2018. Two wheat cultivars were used for the field experiment. The theoretical yield of straw was in the range of 8, 900.9 kg ha-1 (cultivar Sofru) to 9, 648.8 kg ha-1 (cultivar Kraljica). The amount of straw that was collected with machinery and equipment used on the family farm, was from 1, 857.0 (cultivar Sofru) to 2, 234.0 kg ha-1 (cultivar Kraljica). Collection efficiency varied from 21.5% (cultivar Sofru) to 23.7% (cultivar Kraljica). No significant difference was found between the cultivars in collection efficiency. The data obtained in this study indicated problems that may arise in determining the amount of straw that can be taken out of the field by a particular piece of equipment.
