“…This could be explained by the fact, that cereal or cereal-legume mixture used as cover crops were previously utilized as a forage source with high fibre content (Hakl et al 2011), which is not sufficient for high-performing cows. These farms also harvested lucerne at the bud stage which is in line with the best forage quality declared (Hakl et al 2010, Testa et al 2011. From all management methods, only lucernegrass mixture significantly increased forage yield in accordance with the positive effect of mixture to dry matter yield (Bélanger et al 2014).…”

“…For forage legume crops such as lucerne, this point seems not important due to potential of nitrogen fixation (Carlsson and Huss-Danell 2003). The impact of applied technology on lucerne or lucerne-based stand yield was usually investigated under field plot experiment covering large area from advantages of lucerne grass mixture (Bélanger et al 2014), stand establishment (Norton and Koetz 2013), and population density (Lamb et al 2003) to applied harvest management (Hakl et al 2010, Testa et al 2011) in relation to ethanol (Lamb et al 2014) or biogas production (Hakl et al 2012). However relationships among technology, environment condition and yield were not directly investigated, because these studies were usually conducted in one or few sites, under a few treatments with limited explanation power regarding to interaction with environment as well as other technological factor.…”

The aim of this study was to investigate the impact of used technology and environmental condition on lucerne dry matter yield in the regional conditions. During a three year period (2011)(2012)(2013), the investigation was based on management survey in 27 farms in the Czech Republic. Climate conditions significantly influenced yield in some interaction with soil where only combination of dry climate and less fertile soil conditions reduced forage yield. The single soil effect was not significant for forage yield. Applied technology was influenced by both environment and farm characteristic (such as farm size and cow's milk performance) which together significantly explained about 40% of variability of used technological properties. From all investigated technological properties, only cultivation of lucerne in mixture with grasses consistently increased forage yield therefore should be considered as important factor for modelling forage farm yield in the regional conditions.

“…4) content in leaves barely changed with vegetation advancement, the percentage of both NDF and ADF in the stems and the whole plant increased constantly, due to a rising quantity of stems. Most research (Hakl et al, 2010;Mehrdad et al, 2004;Mueller, 1994;Overman and Scholtz, 2005;Thompson et al, 2000) showed that the rising percentage of stems has an increasingly higher influence on the NDF and ADF content in alfalfa plants.…”

Alternative use of alfalfa, for various purposes, including the production of biofuels or food supplement for human alimentation, is a study topic still in its early stages of research. Studying and understanding the biology of alfalfa and the factors with a major influence on it are very important activities. The productivity and quality of alfalfa are two indicators that help determine, in addition to economic value, the way in which alfalfa can be used. Evolution of alfalfa yield and quality depends on many factors, such as the growth stage of alfalfa plants at harvesting. It was observed over three years of vegetation the influence of alfalfa plant growth stage at harvest on plant height, leaves/stems ratio, production of leaves, stems and whole plant (DM -dry matter) per hectare and on quality indicators (CP -crude protein, NDF -neutral detergent fiber and ADFacid detergent fiber). The results showed that, with the advancement of phenological phases, from early bud stage to complete flowering, the total biomass output raised from 2.79 Mg·ha -1 to 4.60 Mg·ha -1, the neutral detergent fiber raised from 48.4-50.6% to 62.0-67.7%, while crude protein content decreased from 21.2-24.0% to 13.3-16.5%. The parameter values were correlated with alfalfa growth stage during the harvesting (significant at the 0.05 and 0.01 probability levels).

“…Chen et al (2012) and Ernert (2014) recommended the first mowing at the plant height of 50 to 70 cm, due to the favourable relationship between yield and crude protein content. Hakl et al (2010) reported very similar plant height (75 to 80 cm) as the appropriate time for the first mowing of lucerne. However, the optimal harvesting time in this case was associated with the development stages buds and first flowers, because, in the later development stages, digestibility of lucerne fodder is drastically reduced (Meyer 2005).…”

The field experiment aimed at determination of influence of autumn harvest on rhythm of the growth of lucerne (Medicago sativa L.) and yield quality of the first cut in the following year was carried out in Spodnji Gabernik (258 m above sea level, 46º15'54.94'' N and 15º34'6.05'' E), in the fourth growth year of the lucerne variety 'Soča'. The experiment was designed as a randomized block in four replications. The individual treatments represented weekly autumn cuttings (1) 24/9/2014, (2) 01/10/2014, (3) 08/10/2014, (4) 15/10/2014 and (5) 22/10/2014. The paper presents data associated with the amount of lucerne dry matter yield (DMY) per treatment compared with the DMY of the first spring cut in the year 2015 (18/05/2015). The growth rhythm of lucerne in each treatment, which took place before the first cut in year 2015, was based on the measurements of the height of the plants. The yield quality was evaluated by NIRS method for determination of crude protein (CP), the net energy of lactation (NEL) and metabolic energy (ME) in dry samples regarding to DMY of each treatment. In autumn 2014, statistically significant higher dry matter yields were obtained in later harvested treatments (5 and 4). Similarly, in spring 2015 the trend of higher crop dry matter yield was observed in treatments harvested later in the autumn of 2014. However, the differences were not significant. Statistically significant differences between treatments were acquired within CPY, NELY and MEY. Before the first mowing, in spring 2015, statistically significant trend of higher plants was also detected in treatments with later cutting in 2014.Key words: lucerne, Medicago sativa, cutting regime, growth rhythm, dry matter yield Agricultura 13: No 1-2: 87-95 (2016) ABSTRACT e placement of a theme park in the form of a Zen garden, as a business opportunity in the Slovenian rural area, is discussed. e design of the garden, with all the major points of a standard business plan, is accurately presented, with a description of the business, branch, and services, market analysis, marketing strategy, nancial projections, and a plan of the work and activities. e nancial aspect is presented as the amount of investment, net present value, and internal rate of return. e amount of investment is estimated at €14.891, which should be reimbursed within 4 years of operations. e estimated internal rate of return is estimated at 16.86%.
