Susceptibility of faba bean variety ‘Merkurʼ to broadbean seed beetle (Bruchus rufimanus) in Latvia النص الكامل
2024
Gailis, Janis | Grase, Zane Gita | Ozolina-Pole, Laura
The broadbean seed beetle (Bruchus rufimanus) is a significant pest of faba bean (Vicia faba) both in Latvia and in many other parts of the world. The objective of this study was to check the susceptibility of the faba bean variety ‘Merkurʼ to the broadbean seed beetle in Latvia, comparing it with other popular varieties: ‘Boxerʼ and ‘Lauraʼ. The trials were conducted in 2021 and 2022 at the Research and Study Farm ‘Peterlaukiʼ in Jelgava County and at a commercial farm in Cēsis County. The larval infestation rate of seeds of different varieties, the survival rate of individuals (larvae, pupae, imagines) in the seeds, as well as the percentage of seeds damaged by the pest in the yield were compared. It was observed that ‘Merkurʼ seeds were significantly less infested than ‘Boxerʼ and ‘Lauraʼ seeds. However, the survival rate of larvae in the seeds of ‘Merkurʼ was similar to that in ‘Lauraʼ seeds and higher than in ‘Boxerʼ seeds. The highest proportion of seeds damaged by the pest was found in the ‘Merkurʼ and ‘Boxerʼ yields, varying between 5–75% between years and trial locations. Therefore, it was concluded that the variety ‘Merkurʼ, evaluated from a practical point of view, does not differ from the other two varieties. Without taking additional plant protection measures, the percentage of seeds damaged by the broadbean seed beetle can significantly exceed the maximum limit (3%) specified in the buyersʼ quality criteria.

Japanese quince (Chaenomeles japonica) is a minor but prospective fruit crop due to the value of fruits and suitability for processing. Research aimed to clarify the incidence of quince leaf and fruit diseases depending on the year and plantation and determine the critical periods of diseases. The study was conducted from 2017 to 2019 in eight commercial Japanese quince plantations across different regions of Latvia. The incidence (%) of leaf and fruit spots and fruit rot was assessed several times during vegetation period. Considerable rot development was observed in only the first year of the study. The incidence of fruit rot in the middle of 2017 ranged from 0.7 to 11.7% depending on the plantation, while in 2018–2019 did not exceed 2% in any of the plantations. The critical period of fruit rot development was determined in the middle of fruit development and time closer to ripeness. Development of fruit spots increased closer to ripeness. In 2017, the incidence of fruit spots fluctuated from 0.7 to 44.0%, in 2018 – 7.7 to 46.0%, and in 2019 – 0.7 to 24.0%, depending on the plantation. The incidence of leaf spots reached high levels at the end of the vegetation periods (21–100% depending on year and plantation). The most critical periods of leaf spot development were the end of fruit development and full ripening of fruits. Determination of the critical periods of quince disease development could be used to create an effective and environmentally friendly disease control system.

2024
Avena, Anita | Ozola, Liene | Ķeķe, Anete
Sambucus nigra has garnered attention in the food industry for its natural colouring and antioxidant properties, mainly due to its high content of anthocyanins, other polyphenols, and vitamins. These bioactive compounds not only contribute to the nutritional impact of food products, but also make it possible to replace synthetic additives that meet the current consumer demand for natural and functional foods. This study provides an overview of the bioactive compounds in Sambucus nigra (black elder) fruits, highlighting their potential health benefits and toxicity concerns. It examines the effect of different processing technologies on the phenolic and cyanogenic glycoside composition of elderberry, emphasizing the need to balance microbial decontamination with the sensory quality and nutritional value of food products. The study also reviews the mechanism of ultrasonic inactivation of microorganisms and the potential of fermentation to reduce toxic compounds in Sambucus nigra fruits, thus contributing to the improvement of food safety and nutritional quality, emphasizing the importance of considering the potential limitations of ultrasound and the use of combined methods to increase efficiency while minimizing the negative impact on both the product and the consumer. Additionally, the study discusses the significance of selecting appropriate processing methods to ensure the safety of elderberry products, given the presence of potentially harmful cyanogenic glycosides and lectins, which can be mitigated through heat treatment and fermentation.

Kadile, Dace | Rivža, Baiba | Vienažindienė, Milita | Rivža, Pēteris
Digital progress in the European Union is a catalyst for economic development. The COVID-19 pandemic significantly accelerated the pace of digitalization, thereby creating not only challenges for the European Union but also new opportunities for economic development in Europe. The present research focuses on an analysis of digital economy and society index scores for Latvia and Lithuania, comparing the performance of both countries with the European Union average. The research aims to identify the critical areas that hinder digital progress in Latvia and Lithuania. Accordingly, the digital economy and society index was analysed for the period from 2018 to 2023. The empirical part of the research includes a sociological survey, and the survey data were analysed in order to identify population needs for and experience in using digital technologies in Latvia and Lithuania. The survey involved 146 respondents. The research results allowed us to identify the critical areas for Latvia and Lithuania to focus on for further digital progress. Latvia and Lithuania both show high scores, well above the EU average, in the ‘digital public servicesʼ component, indicating that both countries have a high level of e-government users and widespread access to digital public services. The results of the sociological survey further confirm this, showing that a large majority of 84.25% of respondents in both Latvia and Lithuania use digital solutions in their daily lives.

Khan, Ahmad Raza | Popluga, Dina
This study explores the impact of climate change, social capital, and gender differences on the resilience of smallholder farmers in South Asia. Analysing data from Bangladesh, India, Nepal, and Pakistan from 2000 to 2020, the researchers have found that climate change significantly reduces agricultural productivity, while social capital acts as a crucial support mechanism. The paper summarizes gender-sensitive interventions in the improvement of adaptive ability and equality in the agriculture sector. It describes innovative farm-level practices and policy measures at various levels to strengthen resilience from environmental challenges. This approach gives room for researchers to find how the elements of climate change, put together with social capital and gender disparities, influence agricultural resilience. The present analysis recaps gender-sensitive interferences aimed at improving adaptive ability and equality in the agriculture sector, describing ground-breaking farm-level performs and policy measures to strengthen resilience against environmental tasks. Data shows that the climate change has a negative impact on agricultural output; therefore, any rise in temperature, change of precipitation, and extreme weather events worsen susceptibility. Social capital is also an essential part in resilience, being a source of resources, information, and support networks that can be drawn on. It calls for the interaction with the opposite gender and gender-sensitive interventions that increase adaptive ability and equality between men and women in agriculture. This study reveals that agri-diversification is pivotal for conservation agriculture enhancing climate resilience in South Asia.
