This study characterizes the self consumption food produced by family farmers in the municipalities Seara and Arabutã, West of Santa Catarina, with regard to economics and dietary diversity. Data collection was carried out during November 2023 to February 2024, in six family production units, distributed in the municipalities in question, through a semi structured form applied during the visits and, of these families, four participated in the quantitative collection of the food produced and its economic values. The sampling of agricultural establishments has considered the presence of own consumption production in the production systems characterize the most relevant production systems in the study region. The results indicate that production for domestic consumption is present in all family production units. Despite the differences related to the intensity and variety of food grown between families, there was a significant diversity of products of animal, vegetable and processed origin, highlighting the importance of this production with regard to health, culture, tradition, economy and autonomy for the families researched.

Strategies for preserving quality include the use of products to manage insect pests, as these can be responsible for direct and indirect damage to seeds. In this scenario, sustainable technologies emerge, among which thyme essential oil (Thymus vulgaris) has demonstrated an effect on mortality and also on repelling insect pests. However, there are few scientific results that portray the effect of oil on the quality of the seed under storage. Therefore, the objective was to evaluate the influence of thyme essential oil (Thymus vulgaris), in its natural (liquid) and microencapsulated form, at doses 0.0; 0.5; 1.0; 1.5 and 3.0 L t-1, during 0, 50 and 100 days of storage, regarding the qualitative characteristics of the stored corn seeds. The experiment was developed in 2023, at UFFS - Campus Chapecó. The Pixurum Creole corn variety was used, which was stored in the laboratory, in non-airtight containers. The essential oil used was obtained from a commercial brand, and microencapsulation was subsequently carried out. At the end, the experimental data were subjected to analysis of variance, using the F test (p≤0.05), and the Tukey mean comparison test (p≤0.05), in the RStudio program. The results demonstrated that the microencapsulated form of application presented lower qualitative losses in the seeds than the natural one. Furthermore, it was observed that, generally, as the doses of essential oil increased, regardless of the storage time, the percentage of seed germination was reduced, making it ideal to work, at most, with doses of up to 1.0 L t- 1.

This analysis allows for the comparison of the presence and activity of nematodes in different agricultural areas, providing insights for integrated pest management and the sustainability of crops. The aim was to analyze soil samples from various agricultural activities in family farming were positive for the presence of nematode pathogens (EPNs). Soil samples were collected from three different areas: Area 01 – fruit cultivation (jabuticaba); Area 02 – fruit cultivation (establishment); and Area 03 – horticulture. After collection, laboratory analyses were conducted on the soil samples, where they were subjected to larvae of Tenebrio molitor to observe potential infections. Finally, isolations were performed, which could be confirmed in repetitions regarding the occurrence of the nematodes. Soil moisture was measured for comparison with the presence or absence of EPNs. For molecular analysis, the captured isolates were sent to the State University of Northern Paraná. Following molecular analysis, the main species identified was Oscheius tipulae, which represented over 93%. The moisture levels in the three areas were 25.60%, 20.60%, and 21.20%, respectively. It was concluded that positive samples with EPNs could be collected from different cultivation areas in family farming.

It is used in several countries not only for food purposes but also for its therapeutic effects. However, to date, there are no studies on the cultivation of this species in Santa Catarina or on the characteristics of the plants under the edaphoclimatic conditions of this state. Thus, the objective of this study was to characterize the protein content, detect phenolic compounds, and assess the antioxidant capacity present in plants of this species grown under the edaphoclimatic conditions of Nova Erechim-Santa Catarina. In this study, samples of whole Lalo plants were analyzed, harvested 180 days after sowing, and cultivated in Nova Erechim. Protein content, total phenolic compounds, and antioxidant activity were analyzed, and compounds were identified using the HPLC method. The results indicate that samples of C. olitorius in the final stage of their growth cycle exhibited protein levels similar to those of bean varieties cultivated in the region, along with the presence of phytochemical components and antioxidant potential. The phytochemical components of C. olitorius samples, including polyphenols, ranged from 7.70 to 20.89 mg GAE/g, with antioxidant activity ranging between 13.23 and 62.82 μmol TE/g of plant samples. The individual compounds detected in the Lalo plant samples were quercetin, epigallocatechin, p-coumaric acid, and syringic acid, with variation among the test conditions used. The compounds myricetin, kaempferol, caffeic acid, pyrocatechol, flavone, gallic acid, and rosmarinic acid were not detected in the samples in any of the six tests conducted Publisher: Universidade Federal da Fronteira Sul Type: Artigo Cientifico 2024-01-01T00:00:00Z
