Abstract:

Field trials were designed to identify the most suitable time for the last cut and to ascertain whether it is possible to alleviate the consequences of improper timing of the cut by using the young and old sward under mixed management for forage and seed. Due to the autumn cut of the aftermath, a significant reduction in herbage dry matter yield and metabolizable energy was obtained in the first and second cuts in the following year. When autumn aftermath had been taken annually for four years, the productivity of the sward significantly declined when the cuts had been taken during the August 15 – October 15 period. The most unsuitable cutting time, when the greatest yield reduction occurred and the adverse effect of autumn aftermath cutting persisted longest, was found to be mid August – beginning of September. When the sward had been cut during the period middle August – beginning of September, a sharp, significant reduction occurred in the content of total and protein nitrogen, water-soluble carbohydrates and starch in roots. The greatest reduction in root mass in the 20 cm soil layer occurred in galega sward when it had been used for forage for four years. In the case of mixed management for forage and seed galega root mass was higher. When old sward of galega was used under mixed management for forage and seed, the negative effects of autumn aftermath cutting were alleviated or eliminated more rapidly.

Abstract:

Demand for local and renewable energy source materials is accelerating the search for new crops for energy production. Goat’s rue or galega (Galega Orientalis Lam.) is known as a long-living and well-adapted rhizomatious legume used mainly for production of high quality forage. Thanks to its strong stem and nitrogen-fixing bacteria, an economically produced and harvested yield is feasible. As an energy source, its yield can be used in an alternative manner. In this paper estimated usage is based on a combination: direct burning of dry material (spring harvest) and ensilaging of summer harvest. Therefore the crop produces 2 yields and gives the best estimated yield. Calculations for production costs are made for pure crop and mixed grasses, since these mixes are most productive. Hauling to the usage site and costs related to material processing are not considered. Results show that establishing of the crop for pure stand and mix with grasses will cost 467.88 and 487.06 € ha-1, yearly costs are 378.56 and 421.81 € ha-1 respectively, crop finishing adds extra 111.38 € ha-1 in both cases.
