Wheat (Triticum) grain is generally used for food due to its grain quality. The two-factorial trial was conducted in the Research and Study farm ‘Pēterlauki’, Latvia, with an aim of finding out the soil tillage and crop diversification in rotation effect on winter wheat grain yield and quality. Two soil tillage systems (traditional and reduced) and three crop rotation schemes with different winter wheat (Triticum aestivum) fore-crops (wheat, oilseed rape (Brassica napus ssp. oleifera), faba bean (Vicia faba)) were used. The trial started in 2009. For this paper data from 2016/2017 and 2017/2018 growing seasons was used. Yields harvested in 2017 were significantly (p is less than 0.001) higher than those in 2018 (on average 7.17 t haE−1 in 2017, 6.18 t haE−1 in 2018). The highest yield (8.06 t haE−1) was gained in the variant where the fore-crop in 2017 had been faba bean. Crop rotation, including only repeated wheat sowings in both years, showed the lowest yield (on average 5.81 t ha E−1). Crop rotation with oilseed rape and wheat showed a significant wheat yield increase in the following two-year period in comparison to to repeated wheat sowings. A year as a factor had a significant (p is less than 0.05) impact on crude protein content (%), Zeleny index, volume weight (g LE−1) and 1000 grain weight (g). Both, volume weight (g LE−1) and 1000 grain weight, were influenced (p is less than 0.05) by the crop rotation and forecrop. Zeleny index depended on all researched factors. Crude protein content was influenced by soil tillage method (p is less than 0.0016) and fore-crop (p=0.0052). Hagberg falling number was not influenced by any of the investigated factors.

Winter oilseed rape is the main oilseed crop in Latvia. High yield production depends on applied plant nutrients, especially nitrogen. Nitrogen is one of the most mobile plant nutrients in the soil and, therefore, nitrogen fertilizer management is an important part of agriculture. The objective of this paper is to evaluate the effect of nitrogen fertilizer rate on nitrogen use efficiency (NUE) in winter oilseed rape. The field experiment was conducted during four growing seasons (2014/2015, 2015/2016, 2016/2017 and 2017/2018) at the Research and Study farm ‘Pēterlauki’ of Latvia University of Life Sciences and Technologies (56° 30.658´ N and 23° 41.580´ E). In total, eight nitrogen rates were used in this experiment (kg ha-1 of N pure matter): N0 or control, N60, N90, N120 (80+40), N150 (100+50), N180 (120+60), N210 (120+60+30) and N240 (140+60+40). All NUE parameters were calculated only for five nitrogen rates (N0; N60, N120, N180 and N 240). Results indicated that the nitrogen fertilizer rate had a significant (p is less than 0.001) effect on winter oilseed rape seed yield. The yield increased until the rate N120 – N180. Nitrogen fertilizer rate also significantly (p is less than 0.001) affected N, P2 O5 and K2 O removal with oilseed rape biomass. N and K2 O removal with seed yield significantly increased until the nitrogen rate N120 – N180, but P2 O5 until N60 – N180. Results showed that the nitrogen fertilizer significantly (p is less than 0.001) affected NUE, nitrogen uptake efficiency (NUpE) and nitrogen utilization efficiency (NUtE), but it did not have a significant (p=0.840) effect on nitrogen harvesting index (NHI). By increasing the nitrogen fertilizer rate, NUE, NUpE and NUtE decreased.

Winter wheat (Triticum aestivum L.) leaf diseases are an important risk factor that influences the productivity and quality of wheat production. The aim of the present study was to review published scientific literature about the possibilities for integrated control of winter wheat leaf diseases. The most common and economically important wheat leaf diseases are Septoria leaf blotch (caused by Zymoseptoria tritici), tan spot (caused by Pyrenophora triticirepentis), yellow rust (caused by Puccinia striiformis), and powdery mildew (caused by Blumeria graminis). The severity of winter wheat diseases has varied significantly over the years and depended on meteorological conditions, variety resistance to pathogen, and tillage system. The crop rotation and an efficient residue management significantly decrease the development of tan spot. The development of Septoria leaf blotch mainly depends on meteorological conditions, but agronomic practice is less important. The use of disease-resistant varieties is the most economical, safe, and effective way to prevent and control wheat leaf diseases. Many European countries have a number of decision support systems for optimizing and minimizing the use of fungicides. Decision support systems are based on control thresholds and meteorological observations. Most used parameters are: air temperature, relative air humidity, and precipitation. These systems have been developed in the countries with a milder climate and a longer vegetation period than Latvia, and systems need to be adapted to Latvian conditions. The main groups of fungicides for disease control in winter wheat are azoles, strobilurin, and carboxamides. The results of many studies about the effectiveness of fungicide groups show that the obtained results differ and further research is needed.

Brown rust caused by Puccinia recondita is a significant disease in cereal growing areas worldwide. On average, brown rust can cause yield losses from 10% to 40% resulting in economic losses. The disease damages the leaves, stems and glumes of cereals. Classification of the pathogen causing brown rust has undergone several revisions. There are two different opinions about the causal agent causing brown rust on rye and wheat. Some scientists consider that the causal agent of brown rust in wheat (Triticum aestivum L.) and rye (Secale cereale) is included in the broad species of P. recondita defined by Cummins, but other scientists consider that there are two species causing brown rust – P. recondita in rye and P. triticina in wheat. There are many studies about the races of P. recondita in wheat: in North America, 70 races are collected every year; in Canada, 35 races have been found; in Europe, 105 races have been found. Unfortunately, there are no studies about the races of the pathogen of rye. P. recondita is a heteroecious fungus with a complicated life cycle. For successful development, the fungus requires cereals as primary hosts and different alternative hosts, depending on the specialization of the pathogen. Specific studies about the biology, distribution and harmfulness of Puccinia recondita in Latvia are necessary. Monographic method was used for this study. The aim of this article is to summarize the information from the literature about Puccinia recondita, the causal agent of brown rust, with emphasis on the occurrence, harmfulness, taxonomy, and life cycle of P. recondita f. sp. secalis.

The concepts of bioeconomy development require the integration of different sectors and economic activities. Bioeconomy helps to achieve the goals of sustainable development. This paper provides an overview of the cooperation for the need of bioeconomy development, examining it from agricultural cooperatives development, theoretical concept and European countries policy and Kazakhstan perspective. The research methods are induction and deduction, monographic, the group interview, statistical data analysis and synthesis, descriptive, matching and comparison and other methods. The cooperation passes through several levels of development – information, consultation, joint action, collective decision-making. The cooperation within farmers (horizontal cooperation) is so far narrow and limited to traditional cooperatives that bring together producers of the same product. New forms of cooperation and more diverse directions in national, regional and local levels are needed to develop the bioeconomy. Partnerships, the interdepartmental and interdisciplinary cooperation based on knowledge and innovation should be established between farmers, agri-food companies and scientific institutions, Kazakhstan and other countries universities. The agricultural and rural development advisory system should be improved, and new measures to promote communication, counselling and cooperation should be introduced.

Catch crops contribute to soil and environmental quality, which has determined a growing interest in their use as a nature-based solution. Though, the introduction of catch crops increases the complexity of farm management and is related with additional costs. In Latvia, the area under catch crops accounts for less than 5% of the arable land, while 30% is bare over the winter. In order to identify the possibilities for promoting of catch crops in Latvia, the objective of the study is to explore the support practices for growing of catch crops in the Baltic Sea region countries. The paper seeks to explore the main benefits associated with the growing of catch crops, followed by the study and synthesis of the main support measures. For the study, numerous information sources have been explored and appropriate research methods applied. Catch crops reduce nutrient leaching from the soil, transfer nutrients to the next crop, improve soil quality, reduce soil erosion, and mitigate climate change; these benefits can translate also at farm level, mainly as reduced N inputs. Growing of catch crops is being increasingly supported in the Baltic Sea countries – as a greening measure and by different agri-environment and climate measures of the RDPs 2014−2020. Growing of economic focus area catch crops (supported in quite a similar approach in these countries) and introduction of agri-environment scheme for catch crops (supported in directly and/or indirectly targeted way) can contribute to the solving of environmental problems and decrease the share of bare land left over the winter in Latvia.

Public participation is needed for nongovernmental organisations (NGO) to function and exist, as the public plays the role of investors by supporting the NGOs financially and thereby providing a quorum needed for the organisation to operate and make decisions. NGOs provide services for defending public interests, and the NGOs members carefully assess their gains from involvement or participation continuation in public organisations, just as if choosing a good or service for consumption. The level of society activity in NGOs sector is low in Latvia comparing with the Western world. To increase it, it is required to contribute to the public’s trust and NGOs transparency. Organisational performance analysis is one of the ways how to provide members with information on performance and funding use, as the members of NGOs wish to be sure that their membership fees and other financial support are effectively used to achieve their goals and defend the interests of their members. The research aims to analyse financial analysis methods used in the NGO sector. The research tasks were set: 1) to analyse the substance of financial analysis of NGO, and 2) to identify shortcomings for a comprehensive analysis of NGO. The research has found that as public participation in NGOs increases, it becomes increasingly important to provide financial transparency in the NGO sector in order to contribute to the public’s trust in the NGOs and make it possible to verify the consistency of funding use with the organisation’s goals and performance.

The aim of this paper is to summarise the experience gained at different levels of tourism destination planning in Latvia, identify the problems encountered during strategy planning and implementation, analyse the causes, and search for solutions. Theoretical aspects of the tourist destination planning have been extensively reviewed in publications, yet the research on what main problems planners have faced during the planning process, has been insufficient. In the last twenty years of Latvian tourist destination planning, at different levels, part of the plans were developed as documents; however, not all of them were implemented. The qualitative research summarises the experience of municipalities and tourism destination planning in Latvia. The research results show formally drafted tourism development documents of different levels and types in Latvia conform to modern planning theory and practice. In some cases even the latest knowledge and experience; create unique, innovative and competitive solutions. Tourism planning at the local level is often a painful process which raises a number of unresolved issues and unimplemented activities. The most significant differences observed from a comparison of theory and good planning practices in tourism development planning in Latvia are that the planning process is implemented within the boundaries of one municipality without taking into account the larger boundaries of tourist destinations. The involvement of entrepreneurs has only been formal and major, large-scale investment projects have not been planned or implemented.

Given the intensive competition between rural businesses, building and managing good corporate reputation of rural businesses is gaining its popularity among business owners, marketers as well as among scholars. Building and managing good corporate reputation is considered to be one of the crucial goals for businesses that lead to successful competition in ever changing business world. The aim of this research is to determine dimensions and attributes for building good corporate reputation in the framework of rural businesses. To reach the aim, this paper adopts analysis and synthesis of scientific and practical literature in the field of corporate reputation management and, focus group discussion. 23 attributes of corporate reputation representing 7 corporate reputation dimensions were generated from scientific and practical literature. Generated attributes were provided for the evaluation and discussion during the focus group discussion to 7 representatives of rural businesses’ stakeholder groups, namely: customer, employee, supplier, business owner, media, local community, and expert. Empirical research proved 7 rural businesses’ corporate reputation dimensions: Products and Services, Innovation, Workplace, Governance, Citizenship, Leadership and Performance, each of the dimensions constituting of 3−4 corporate reputation attributes. For the further research, quantitative research to test corporate reputation dimensions and attributes and calculate its weights in the context rural businesses is necessary.

The study concentrates on housing vulnerability during the post-crisis period in Latvia and how it has impacted vulnerable groups, particularly seniors. Housing vulnerability includes objective and subjective factors. Seniors 65+, especially those seniors who live alone are one of the vulnerable groups in sense of housing security. It could be characterized by parameters of housing quality and housing expenses adequacy. The EU policy examines perceptions of insecurity in few areas, including housing security and old-age income insecurity – of not having an adequate income in old age. The number of single senior 65+ households is increasing in both rural and urban areas. The study explores housing vulnerability for older persons – seniors 65+, one of social groups in disadvantageous economic situation. Authors explore how housing vulnerability affects seniors, especially those who are over the age of 65+ and are living alone. The challenging issues were construction of theoretical background integrating housing security during social changes in the post-crisis period with disadvantageous situation of seniors 65+. The comparative quantitative approach is based on data from descriptive statistics. The research design is quantitative comparative analysis. To make a comparison, there were selected two groups: single seniors 65+ and all households. The proposition is that in the post-crisis period housing vulnerability for seniors 65+ was decreasing, but differs from average parameters of housing vulnerability for total population. The restriction of current study is analyses that cover only single seniors 65+. The results show significant differences in housing quality and proportional housing maintenance expenditures between single seniors 65+ and all households.
