Šajā pētījumā iegūtie ražas stabilitātes rezultāti vasaras miežu genotipu maisījumiem un kombinēto krustojumu populācijām liecina, ka ģenētiskā daudzveidība šķirnē var nodrošināt ražas stabilitāti pa gadiem un audzēšanas vidēm. Vienkāršo un salikto populāciju ražas rezultāti skaidrojami ar mazāku vecākaugu skaitu un to ražas potenciālu, jo atbilstošu vecākaugu izvēle ir viens no būtiskākajiem kritērijiem šķirņu veidošanā.

The growth in organic and low-input farming practices is driven by both market demand for high quality, safe food, and European Union policy support, and these types of farming practices are considered in European Union policies for sustainable production, food quality, healthy life, and rural development. However, many constraints to the development of low-input and organic dairy farming supply chains have been identified, including economic, political, and technical constraints. In order for these types of supply chains to develop and provide further benefits to society, innovations are required to improve their sustainability. However, an innovation will only be taken up and result in desirable change if the whole supply chain accepts the innovation. In this paper, Q methodology is used to identify the acceptability of dairy supply chain innovations to low-input and organic supply chain members and consumers in Belgium, Finland, Italy, and the United Kingdom. A strong consensus existed across all respondents on innovations that were deemed as unacceptable. The use of genetically modified and transgenic organisms in the farming system and innovations perceived as conflicting with the naturalness of the production system and products were strongly rejected. Innovations that were strongly liked across all participants in the study were those related to improving animal welfare and improving forage quality to be able to reduce the need for purchased concentrate feeds. Only minor differences existed between countries as to where the priorities lay in terms of innovation acceptability.

Due to the overlap of many disciplines and the availability of novel technologies, modern agriculture has become a wide, interdisciplinary endeavor, especially in Precision Agriculture. The adoption of a standard format for reporting field experiments can help researchers to focus on the data rather than on re-formatting and understanding the structure of the data. This paper describes how a European consortium plans to: i) create a “handbook” of protocols for reporting definitions, methodologies and parameters measured/calculated; and ii) how a data-template for field data was created and will be linked to the “handbook”. The overall goal of the EU-funded project Solutions for Solutions for improving Agroecosystem and Crop Efficiency for water and nutrient use (SolACE) is to help European agriculture face major challenges, such as increased rainfall variability and reduced use of N and P fertilizers in order to satisfy both economic and ecological goals. The “Handbook of Protocols” and the “Data Template” have been created to achieve a flexible, standard, and clear documentation linked with the data itself to facilitate interchange of data among project’s partners and any statistical analysis and modelling of different datasets.

The necessity to increase genetic diversity in agriculture has been widely discussed during the last decades. Heterogeneous populations is one of the ways to increase genetic diversity in varieties of self-pollinating cereals. The aim of this research was to compare grain yield, its stability, foliar diseases severity and competitiveness against the weeds of spring barley (Hordeum vulgare) populations and homogenous varieties. Field trials consisting of three types of populations (simple, complex and composite cross populations – CCP) containing different levels of diversity and three check varieties were carried out during 2015-2018 under organic and conventional farming systems. No one of the populations had a significantly higher average yield than any of the check varieties. CCP1 showed a tendency to be more productive under organic growing conditions and can be characterized as widely adaptable to various growing conditions with a significantly higher yield as the average overall environments. One of the complex populations showed adaptability to favorable growing conditions and yield insignificantly higher than overall average. Other studied populations can be characterized with wide adaptability and various yield levels. For most of the populations under organic and conventional conditions, a significantly lower net blotch (caused by Pyrenophora teres) severity was observed in comparison with the most susceptible variety; infection with powdery mildew (caused by Blumeria graminis) lower than for check varieties was observed under organic growing conditions, whereas such trend was not observed under conventional conditions. All populations had a significantly lower crop ground cover and slightly lower competiveness against weeds than the variety with the best competitiveness.
