The domestic biogas market has been developing rapidly, and legislation (The Act) supporting the use of renewable energy sources has come into force. In light of this act and investment support from national programs co-financed by the European Union (EU), the total number of biogas plants has recently increased from a few to 670. The total capacity of electricity generation of those 670 installed plants exceeds 360 Megawatts (MW) (as of mid-2018). Such dynamic growth is expected to continue, and the targets of the National Renewable Energy Action Plan are projected to be met. The use of waste material, which was urgently needed, was the original aim of biogas plants. However, in certain cases, the original purpose has transformed, and phytomass is very often derived from purpose-grown energy crops. Maize is the most common and widely grown energy crop in the Czech Republic. Nevertheless, maize production raises several environmental issues. One way to potentially reduce maize’s harmful effects is to replace it with other suitable crops. Perennial energy crops, for example, are possible alternatives to maize. A newly introduced species for the conditions of the Czech Republic, Elymus elongatus subsp. ponticus cv. Szarvasi-1, and some other well-known species—Phalaris arundinacea L. and Miscanthus × giganteus—are suitable for Czech Republic climate conditions. This paper presents the findings of the research and evaluation of environmental, energy-related, and economic aspects of growing these crops for use in biogas plants. These findings are based on 5-year small-plot field trials. The energy-related aspects of producing Elymus elongatus subsp. ponticus cv. Szarvasi-1, Phalaris arundinacea L., and Miscanthus x giganteus are reported on the basis of experiments that included measuring the real methane yield from a production unit. The economic analysis is based on a model of every single growing and technological operation and costs. The environmental burden of the individual growing methods was assessed with a simplified life cycle assessment (LCA) using the impact category of Climate Change and the SimaPro 8.5.2.0 software tool, including an integrated method called ReCiPe. The research findings show that Szarvasi-1 produces 5.7–6.7 Euros (EUR) per Gigajoule (GJ) of energy, depending on the growing technology used. Szarvasi-1 generates an average energy profit of 101.4 GJ ha−1, which is half of that produced by maize (214.1 GJ ha−1). The environmental burden per energy unit of maize amounts to 16 kg of carbon dioxide eq GJ−1 compared with the environmental burden per energy unit of Szarvasi-1, which amounts to 7.2–15.6 kg of CO2 eq GJ−1, depending on the yield rate. On the basis of the above-mentioned yield rate of Szarvasi-1, it cannot be definitively recommended for the purpose of biogas plants in the Czech Republic.

This article pursues an innovative dimension of social entrepreneurship in the agricultural sector that keeps rural areas viable, so-called social farming. Social entrepreneurship appears as an essential driver in the European economy and it heads toward new opportunities mainly through its impact on social integration, economic sustainability, and fair society. Social farming and social farms can successfully respond to the challenge of social exclusion and lack of social services provision and other opportunities in rural areas through alternative therapeutic activities, sheltered working places or integrative educational activities in a farm environment. From this perspective, a social farm should correspond to the definition of a social enterprise. By introducing the basic frames of social entrepreneurship and social farming in general and in the Czech Republic, and by concentrating on fifteen Czech social farms, this paper presents an insight into this retro-innovative practice of social integration systems in the countryside. It mainly answers the question, whether social farming complies fully with social entrepreneurship stream, and it explores the role of the social farm in rural development by using semi-structured and in-depth interviews.

Historically, agriculture always fulfilled a social function as well. However, its intensification taking place in the 20th century brought about a number of changes accompanied by putting this and a number of other non-productive functions in the shade. However, recent years have seen the establishment of agricultural directions that contribute to their renewal. This also includes social farming. Social farming is the most complex component of the concept “green care”. In its current form, it creates room for providing for the people who have hardly any chances on the labour market and for their involving in farming activities. While in a number of European countries this concept has been used for many years, in the countries of Central and Eastern Europe it has still been in the early stages and has not been formally defined in many countries yet. In the Czech Republic, the concept of social farming has been developed approximately since 2013, growing and gaining in importance continuously. The article introduces the concept of social farming and describes its current situation in the Czech Republic. The data were obtained through questionnaire surveys and directed interviews in the field. As part of the analysis of the structure of social farming in the Czech Republic, the selected set of thirty entities involved in social farming is described in terms of the structure of the farming production, the main target groups of clients and the funding sources.

This paper deals with the assessment of cultivation of bread wheat (Triticum aestivum L.) and oat (Avena sativa) grown in Central Europe within the conventional and organic farming systems in terms of greenhouse gas emissions and economic profitability. Organic farming may be one of the tools for mitigation of greenhouse gas emissions from agricultural production. In the context of crop production, cereals rank among the most commonly grown crops and therefore bread wheat and oat were chosen. The Climate change impact category was assessed within the simplified LCA method and the production of greenhouse gas emissions expressed in CO2e per the production unit was calculated. Economic balance of the cultivation of monitored cereals was compiled based on the yields, farm gate prices and costs. On its basis, the cultivation of wheat within the organic farming system appears to be the most profitable. From an environmental point of view, the emission load of the organic farming system is reduced by 8.04 % within the wheat production and by 15.46 % within the oat cultivation. Therefore, the organic farming system in the Czech Republic appears to be more environmentally friendly and economically efficient within the cereals production.

As part of the study, growing of selected crops (strawberries, garlic, carrot) in conventional and organic farming systems in the Czech Republic was evaluated. For evaluation, the simplified LCA analysis was used. It is focused on the production of greenhouse gases expressed in the carbon dioxide equivalent (CO2e) per one unit of production. Emissions were calculated for agricultural phases – agricultural technology, fertilizers, pesticides and field emissions – using the IPCC methodology. There are evident differences in subprocesses and in the total emission load between conventional and organic farming systems. With strawberry growing, the GHG emission production is higher within the organic farming system due to low yields. With carrot and garlic growing, the organic farming system is more environmental friendly in terms of GHG emissions.Keywords: organic farming, GHG emissions, plant production, LCA

Hulled wheat species (einkorn, emmer, spelt) are presumed to be an alternative to bread wheat in organic agriculture since the yield penalty is less pronounced under organic farming and generally higher prices can be achieved for specialty grains. The present study analyzed differences between wheat species with respect to biomass production, harvest index, grain yield and protein content. Spring hulled wheat genetic resources and bread wheat check cultivars were grown in organic field trials in the Czech Republic and Austria between 2010 and 2012. Generally, hulled wheat species were inferior in grain yield and distribution of assimilates to the grain compared to modern bread wheat. Biomass production of some emmer and spelt landraces was similar to bread wheat. A higher protein content (+3–6 %) was observed for spelt, however, considering protein yield the differences between spelt and bread wheat became less pronounced. With respect to the recent high market demand for spelt and the absence of available spring grown varieties some of the landraces were identified as valuable resources for the development of spring spelt varieties suitable for organic farming.

This study evaluates the impact of selected potato farming and processing activities on the environment in terms of greenhouse gas emissions. The Life Cycle Assessment (LCA) methodology was used for this evaluation, and was applied to products cultivated under both conventional and organic production, and processed under technological conditions common in the Czech Republic. Farm questionnaires were supplemented with information from the scientific literature to acquire the necessary data for modelling. The SIMA Pro software and the ReCiPe Midpoint (H) method were used for simulation. The results show a lower level of emissions under organic production (0.126 kg CO2e per kg of potatoes, compared with 0.145 kg CO2e per kg of conventionally grown potatoes). However, this benefit is cancelled out by higher emissions due to the transportation of organic products over long distances.

Seven cultivars of common buckwheat were tested in field trials under two levels of nitrogen fertilisation on two experimental sites during 1998–2000. The aim of the experiments was to evaluate the influence of cultivar, nutrition and year on main technological quality parameters (thousand achenes weight, volume weight, proportion of fractions on sieves 4.5 and 4 mm, proportion of husks and yield of groats). The differences were observed between buckwheat cultivars in all observed parameters of technological value. Nitrogen fertilisation before sowing (50 kg.ha–1) did not influence any parameter. On the contrary, buckwheat technological value was influenced by sequence weather (particularly rainfalls) during flowering and achenes formation periods (July). The influence of year was manifested especially on development of endosperm and husks of achenes. Better growing conditions on experimental site Uhříněves caused lower values of volume weight, lower proportion of pericarp (husks) and considerably higher proportion of fraction over 4.5 mm.

The objective of this study was an improvement on oat identification procedure for laboratory applications, and the comparison of albumin-globulin and avenin protein patterns in five hulled and naked oat cultivars: Abel (CZ) and Izák (CZ) – naked oats, Auron (CZ), Edmund (D) and Expander (D) – hulled oats. The last object of this study was the authenticity verification of standardly prepared meal samples with various proportions of admixture. It was confirmed that avenins, characterised under SDS-PAGE conditions, are reliable implements for the identification of oat cultivars. It was found that oat grain contains, on the basis of Osborne fractionation, another significant protein fraction – glutelins. The question of the protein fraction analysis that was used for the admixture identification stays still open. In sufficiently different cultivars, the certainty of the admixture detection in meal samples may be high. Nevertheless, in other cases (higher cultivar similarity) it will be necessary to use some other, more sensitive techniques.

The aim of this study was to determine the most sensitive growth stage of common buckwheat to frost temperatures and evaluate differences in frost resistance among varieties. A modified field-laboratory method was utilised for the study on four varieties of common buckwheat. The lethal temperature (LT50) was determined for all variants. The critical time of frost action (Lt50) was determined for the lethal temperature and for the most sensitive growth stage. Buckwheat is most sensitive to frost temperature from the stage of primary leaves to the stage of two secondary leaves. Differences among the growth stages developed with plant hardening during the growth. The lethal temperature of buckwheat was in the range –1.3 to –2.9°C depending on the stage of development and growing conditions. The critical time of frost action (temperature –2°C) was in the range 4.3 to 5.9 hours. Varieties Pyra and Emka were most resistant from chosen varieties.

As water deficiency becomes a more frequent cause of the reduction in wheat yield levels, the search for donors of drought tolerance to be bred into adapted land races becomes urgent. Drought tolerance has been evaluated by the ud 13ud C discrimination method in six land races of emmer wheat (ud Triticum dicoccumud SCHRANK), compared with land races, obsolete cultivars and modern varieties of soft wheat (ud Triticum aestivumud L.). The results of a two-year trial show that most of the genetic resources of emmer wheat, and intermediate land races of wheat are predisposed to drought tolerance. These varieties respond to dry conditions more sensitively, as they close their pores earlier (a lower value of the discrimination of ud 13ud C isotope). As for other land races and the top modern varieties of soft wheat, they are not thought to be predisposed to drought tolerance and their crop stands are liable to serious damage

Twenty samples of the aboveground biomass of Amaranthus cruentus (varieties Olpir, Amar 2 RR-R 150, and A 200 D) and A. hypochondriacus (variety No. 1008) were analysed to determine their nutritional value during the experimental period covering five growth stages from inflorescence emergence till full ripening of grain. During plant growth, from day 80 to day 120 of cultivation, the nutritional value decreased. This was demonstrated by an increase in insoluble fibre and a reduction in crude protein content. The content of neutral detergent fibre (NDF) in the dry matter increased from 356 to 420 g/kg (P < 0.01); acid detergent fibre (ADF) from 238 to 286 g/kg (P < 0.01); acid detergent lignin (ADL) from 22.9 to 53.4 g/kg (P < 0.01). The content of crude protein in the dry matter of the investigated amaranth varieties decreased from 174 to 109 g/kg (P < 0.01). In the Czech Republic the aboveground biomass of the cultivated A. cruentus and A. hypochondriacus could be used as a good source of fibre and protein in animal diets when harvested in the period from day 80 to 90 of cultivation.

Proso millet belongs to the oldest cereals that human is using. Eight varieties of proso millet were cultivated in Ceske Budejovice from1998 to 2000 and Cerveny Dvur from 1999 to 2000. The crude protein content was determined according to Kjehladl method and amino acid content was determined chromatographically after acid and oxidative acid hydrolysis. Although the protein content of proso (11.6% of dry matter) was similar to wheat, the grain of proso was significant richer in essential amino acids (leucine, isoleucine, methionine) then wheat. Hence, the protein quality of proso (Essential Amino Acid Index) was higher (51%) compared to wheat. The proso grain contained about 3.3 g kg−1 of the limiting amino acid-lysine. Significant differences in protein and its quality were found among the evaluated proso varieties. The varieties Toldanskoe and Lipetskoe were the most different from the others in protein and amino acid content and Amino Acid Score of individual acids. They had the lowest content and quality of protein. The seed coat of these varieties was red. The amino acid and protein content was significantly influenced by weather during the year. Dry conditions caused an increase of protein but its quality was decreased.

Forty samples of dry above-ground biomass of two species and four varieties of Amaranthus cruentus (varieties Olpir, Amar 2 RR-R 150, and A 200 D) and A. hypochondriacus (variety No. 1008) were analyzed to determine their nutritional value during the experimental period covering five growth stages since inflorescence emergence till full ripening of grain from day 80 to day 120 of cultivation. The content of crude protein in the investigated amaranth varieties significantly decreased (from 158.2 ± 1.20 - 185.4 ± 2.33 to 103.8 ± 1.20 - 113.1 ± 0.01 g/kg) as well as did the crude ash content (from 169.9 ± 0.14 - 192.2 ± 0.42 to 129.7 ± 0.14 - 138.4 ± 0.21 g/kg). In contrast, the ether extract content significantly increased (from 12.2 ± 0.14 - 15.9 ± 0.28 to 28.0 ± 0.28 - 36.4 ± 0.14 g/kg) as well as crude fibre (from 144.9 ± 2.12 - 170.0 ± 3.68 to 183.6 ± 7.00 - 276.0 ± 1.20 g/kg), and gross-energy (from 16.6 ± 0.03 - 17.2 ± 0.07 to 18.1 ± 0.14 - 18.4 ± 0.01 MJ/kg) between days 80 and 120 of cultivation. The relatively high content of crude protein in the aboveground biomass in the period between days 80 and 90 of cultivation suggests that the plants could be used as a nutrient substitute for conventional forages.

The effects of environmental conditions (year, growing site) on protein compounds in buckwheat (Fagopyrum esculentum Moench) were studied. Small-plot experiments with four buckwheat cultivars (tetraploid Emka and diploid Kora, Pyra, and Krupinka) were established in two growing sites in 1999 and 2000. Crude and pure protein content, proportion of protein solubility fractions, SDS-PAGE of protein fractions, and immunoassay of gluten-like proteins were determined in buckwheat flour. The growing site had the most significant effect on variability of crude protein content. On the contrary, pure protein content was most of all affected by year. Apparently a higher occurrence of later developed buckwheat seeds in 1999 harvest (as a consequence of weather abnormalities) could generally cause lower content of pure protein in this year (7.32 %) than in 2000 (9.10 %). Alcohol-soluble protein fraction (prolamins like proteins, PLP), considered as inconvenient for gluten-free diet, was generally found at low level, but at the average of experiment, signifícant differences (P < 0.05) between years 1999 and 2000 were recorded, 2.12 and 5.37 % of crude protein, respectively. On the other hand, specific determination of harmful gluten-like proteins (GLP) by immunochemical assay (ELISA) revealed, that in the all tested samples their contents were below the detection limit of the method 12.5 mg.kg-1. Obtained SDS-PAGE subunit profile of AGLP was divided into four groups with range of molecular weight 5-51 kDa. PLP profile was only represented by a double-band with 17 kDa and by a band with molecular weight of about 8 kDa.

Ten varieties of winter spelt wheat Triticum spelta L. (Ostro, Altgold, KR 489-11-15, Oberkulmer, Ostroschwarzer, Lueg, H9227, H9228, Rouquin, Hercule) and winter common wheat Triticum aestivum L. variety Samara were cultivated in České Budějovice under the low input conditions during years 1996–1998. A mixed crop was cultivated in the preceding year and no nitrogen fertilisation was applied after the foregoing crop harvest. Chemical composition was analysed in the wheat and spelt grains — content of total nitrogenous compounds was determined using Kjeldahl method and amino acid contents were determined using an analyser AAA-339. Mean content of nitrogenous compounds in spelt grains was for about 0.5 % higher than in common wheat grain and this difference was not statistically significant. Old Swiss varieties Ostro (12.52 %) and Oberkulmer (12.60 %), and also new breeding material KR 489-11-15 (13.72 %) had a little higher content of nitrogenous compounds. KR 489-11-15 had also higher content of lysine (4.21 g/kg). There was found the positive correlation between nitrogenous compounds and lysine contents. Within essential amino acids, there were observed significantly increased contents of lysine and threonine among varieties KR 489-11-15, Oberkulmer and Rouquin. From the viewpoint of nutritional value (content of essential amino acids), it would be suitable to focus on the new breeding material KR 489-11-15.
