Many microorganisms such as arbuscular mycorrhizal fungi (AMF), plant growth promoting rhizobacteria (PGPR) and Trichoderma spp. can form a symbiotic association with host plants, which can have a significant impact on plant growth and yield. In two years experiment, we investigated the possible role of seven different treatments of microbial inoculates to improve the potato tubers production and quality under irrigated and non-irrigated conditions. Potato cultivar "Desiree" was used with seven treatments of mixture of microbial inoculates including AMF, PGPR and Trichoderma spp. in 64 experimental parcels. The results indicated that the mycorrhizal colonization intensity and mycorrhizal frequency were increased in non-irrigated treated and the control plants over the two years. Most of the treatments did not show arbuscular abundance in both the years except the mixture of Rhizophagus irregularis MucL41833+Pseudomonas brassicacearum (41%), R. irregularis MucL41833+ Paraburkholderia phytofirmans (24%) and Trichoderma asperelloides A (33%). Starch content was similar between different treatments in both the years, without significant differences with control plants. In 2020, the highest starch value was found in P. phytofirmans PSJN treatment with (17.16%) mean under irrigated and non-irrigated conditions. In 2021, the highest starch value among the irrigated parcels was found in R. irregularis MucL41833 treatment (12.29%). In terms of total phosphorus content, the control treatment in the second year (2021) gave the highest total phosphorus content in the irrigated conditions (0.69 mg kg-1) followed by the mixture treatment of the microbial inoculates treated plants R. irregularis MucL41833 and P. phytofirmans (0.68 mg P kg-1). For the tubers yield, the treated plants under irrigated conditions gave the highest mean. In the first year, P. phytofirmans PSJN gave the highest yield (15.21 kg/m2) under irrigation conditions, while in the second year, R. irregularis MucL

Organic soy production, particularly for feedstuff in organic animal husbandry, is needed in Hungary and the EU regions. Soybean producing crop area in Hungary has increased in the last years, however, the agroecological potential would allow for a larger soybean production area. This study presents the soybean market in Hungary, and the role of soybeans in protein supply in food and feed, summarising the critical elements of organic soybean production from variety selection to marketing. During the field research, the effects of the agronomical environment on yield potential factors were examined. We aimed to determine how different row spacing and tillage systems affect organic soybean yields of different varieties, with particular attention to the dry region, and determine the specific methods and varieties of soybean that favour these areas. We found that the tillage (plough/grubber), the spacing (wide/narrow), and the variety effects were all significant on morphological variables. The most remarkable difference was seen in plant height and the number of pods per plant, while the number of nodes was also highly impacted by tillage treatment and variety. The nutrition variables were significantly different, mainly as an effect of tillage and spacing interaction with significantly different plant responses of varieties.

Agriculture can benefit from crop diversification to facilitate its transition to more sustainable agrifood systems. However, these practices remain rare in Europe. One major barrier is the existence of sociotechnical lock-ins. To clarify the dynamics at work, we analyzed the relationships between actors involved in 23 crop diversification experiences across 11 European countries. The novelty of this paper lies in the systemic analysis of the network of actors involved in crop diversification experiences. Using data from qualitative interviews and cognitive mapping approaches, we identify and describe the role of actors and the key relationships in crop diversification and detect relationships that are currently missing. Our study shows that in the different European countries, similar relationships act as levers or barriers to crop diversification, with farmers and researchers playing a crucial role. The most important cognitive factors that influence the choice of farmers to diversify are environmental and health concerns and the desire to make profit and innovate. We relate the cognitive factors to organizational, technical, economic, and political factors and suggest levers for crop diversification based on successful crop diversification experiences.

The European Commission recently set a target of increasing the area of organic agriculture to 25% by 2030. To achieve this, it is imperative to understand current nutrient use patterns and identify sustainable nutrient supply opportunities. To that end, this study assessed the sustainability of the current nutrient origin and supply of 71 arable organic farms in 8 European regions. Defcient nutrient supply was found on 24%, 66%, and 56% of farms for nitrogen, phosphorus, and potassium, respectively. On average, we show a moderate surplus for nitrogen (28 kg ha−1), while phosphorus and potassium balances were close to zero (−1 and 2 kg ha−1, respectively). Large variation between countries and farm types shows a divide between more intensive systems relying on external inputs, and less intensive systems facing nutrient defcits and lower outputs. We show, for the frst time, the extent of current use of external input types, where conventional manures supplied 17–26% of external nutrients and inputs from non-agricultural origin supplied 31–41%. A large proportion of nutrient sources within the last group are materials derived from urban wastes. The sustainable expansion of the organic sector will require increased use of locally available recycled fertilizers from urban wastes, and acceptance of such sources by organic farmers is shown to be high, provided they are considered safe.

The aim of the research is to assess the behaviour of the consumers of organic products, witha particular focus on the frequency of consumption, the groups of purchased products,the preferred sales channels, the consumer motivations, and the impact of the COVID-19pandemic on the market development. The data from the online questionnaire survey wereanalysed by descriptive statistical and relationship analysis methods. In 2020 and 2021,the frequency of purchase of organic products increased. The regular customers are mainlymiddle-aged, highly educated women with higher incomes, who mostly buy fruit andvegetables, mainly in discount stores. The respondents with relatively low frequency buydirectly from organic producers, although the use of short supply chains could bea remarkable price-reducing factor.

Deficient nutrient supply was found on 24%, 66%, and 56% of farms for nitrogen, phosphorus, and potassium, respectively. On average, we show a moderate surplus for nitrogen (28 kg ha−1), while phosphorus and potassium balances were close to zero (− 1 and 2 kg ha−1, respectively). Large variation between countries and farm types shows a divide between more intensive systems relying on external inputs, and less intensive systems facing nutrient deficits and lower outputs. We show, for the first time, the extent of current use of external input types, where conventional manures supplied 17–26% of external nutrients and inputs from non-agricultural origin supplied 31–41%. A large proportion of nutrient sources within the last group are materials derived from urban wastes. The sustainable expansion of the organic sector will require increased use of locally available recycled fertilizers from urban wastes, and acceptance of such sources by organic farmers is shown to be high, provided they are considered safe.

Agriculture can benefit from crop diversification to facilitate its transition to more sustainable agrifood systems. However, these practices remain rare in Europe. One major barrier is the existence of sociotechnical lock-ins. To clarify the dynamics at work, we analyzed the relationships between actors involved in 23 crop diversification experiences across 11 European countries. The novelty of this paper lies in the systemic analysis of the network of actors involved in crop diversification experiences. Using data from qualitative interviews and cognitive mapping approaches, we identify and describe the role of actors and the key relationships in crop diversification and detect relationships that are currently missing. Our study shows that in the different European countries, similar relationships act as levers or barriers to crop diversification, with farmers and researchers playing a crucial role. The most important cognitive factors that influence the choice of farmers to diversify are environmental and health concerns and the desire to make profit and innovate. We relate the cognitive factors to organizational, technical, economic, and political factors and suggest levers for crop diversification based on successful crop diversification experiences.

The aim of the research is to assess the behaviour of the consumers of organic products, witha particular focus on the frequency of consumption, the groups of purchased products,the preferred sales channels, the consumer motivations, and the impact of the COVID-19pandemic on the market development. The data from the online questionnaire survey wereanalysed by descriptive statistical and relationship analysis methods. In 2020 and 2021,the frequency of purchase of organic products increased. The regular customers are mainlymiddle-aged, highly educated women with higher incomes, who mostly buy fruit andvegetables, mainly in discount stores. The respondents with relatively low frequency buydirectly from organic producers, although the use of short supply chains could bea remarkable price-reducing factor.

Although input use in organic agriculture is strictly regulated, and significantly less contentious inputs are applied in organic than in conventional farming systems, copper, mineral oil, external nutrient input, anthelmintics, antibiotics and vitamins are still commonly used among organic farmers in the EU, partly due to the scarce availability of alternative products and the difficulty of implementing preventive strategies. Moreover, besides the direction set by the European Commission’s organic regulation, only a handful of policy instruments exist at national levels to reduce the use of these contentious inputs. The purpose of this paper is to discuss the results of the RELACS EU-funded project about the current use of copper, mineral oils, external nutrient inputs, anthelmintics, antibiotics and vitamins in organic farming in the EU. The paper is based on six internal reports developed in RELACS which relied on international surveys, in-depth interviews, multiple case study methods, database-based calculations, secondary data sources, plus a survey independent from the reports to map existing policy instruments and voluntary initiatives in the EU aiming to reduce the use of the six input categories. As a result, the paper gives a comprehensive overview of the current consumption of the six contentious inputs within the organic sector, highlighting potential alternative strategies in the pipeline, available preventive measures and the willingness of farmers towards adopting these solutions. It also informs about specific policy instruments already in force, as well as about ongoing voluntary initiatives to reduce contentious inputs. Due to the current dependence of organic farming systems on the six categories of contentious inputs, any sudden phase-out or ban on their usage would do more harm than good to the organic sector. Therefore, gradual, data-driven reduction measures are needed, which require significant further investments in targeted research, and in

Plant genetic resources (PGRs) serving as a wide genetic pool of tomato germplasm can provide a solid base for recent breeding efforts to increase consumer acceptance towards the taste and the phytonutrient properties of novel tomato varieties. Old varieties and landraces were abandoned by producers due to unfavorable phenotypic characteristics; however, their high adaptability and nutritional properties are inevitably valuable. This study aims to investigate the impact of open-field vs. protected production on various bioactive compound parameters and on the antioxidant status of seven indeterminate-type tomato PGRs in an organic production system for two years (2015–2016). Genotype main effect plus genotype × environment interaction (GGE) biplots were created for visualizing the which-won-where concept of the PGRs investigated. The GGE analysis revealed that the phytonutrient content of certain PGRs is less dependent on location and more influenced by differences in microclimatic conditions. “Balatonboglár”, “Mátrafüred” and “Fadd” PGRs performed better in a polytunnel, while Tarnaméra provided better results in an open field. “Máriapócs” and “San Marzano” showed a relative independence from production location in terms of their measured phytonutrient values. These findings enrich the nutritional datasets of tomato landraces, which support the in situ conservation and utilization of PGRs in breeding programs.
