ABSTRACT

Introdução: É notório que a alimentação e a nutrição adequada constituem requisitos indispensáveis para a promoção e a proteção da saúde. Objetivo: Contribuir para a melhoria do acesso a alimentos saudáveis de famílias em um Bairro da periferia urbana do Município de Sobral através de hortas comunitárias, orgânicas e sustentáveis como estratégia de promover Educação Alimentar e Nutricional. Métodos e Materiais: Estudo descritivo com características de intervenção comunitária sob a abordagem qualitativa. A amostra inclui 15 pessoas de famílias beneficiárias do Programa Bolsa Família, acompanhadas pelo Centro de Saúde da Família. Foram realizados quatro encontros educativos sobre alimentação saudável com enfoque na inclusão de frutas, legumes e verduras. Além, do manejo de hortas para o cultivo do próprio alimento. Resultados: Os encontros tiveram duração de 8 horas ao dia, totalizando 24 horas. O momento foi oportuno para treinamento ofertado por um técnico em olericultura orgânica pela entidade parceira, que transmitiu os conhecimentos de maneira prática, em que os participantes aprenderam a preparar a terra, a semear, plantar, regar, colher. No decorrer do treinamento a nutricionista pesquisadora, transmitiu informações nutricionais. Os encontros aconteceram em dias seguidos, nos turnos manhã e tarde. Conclusão: Diante do que foi vivenciado, a pesquisa se mostrou útil para melhoria do grau de conhecimento das participantes, promoveu reflexão crítica sobre a segurança alimentar e nutricional. Ressaltou a importância de se cultivar o próprio alimento para torná-lo acessível.


This study aims at contributing to the improvement of access to healthy food for families in a neighborhood of the urban outskirts of the Municipality of Sobral through community organic and sustainable vegetable gardens as a strategy to promote Food and Nutrition Education. It is a descriptive study with characteristics of community intervention using a qualitative approach. The sample includes 15 people from families benefited from the Family Grant Program (Bolsa Família), accompanied by the Family Health Center. Four educational meetings were held on healthy eating with a focus on the inclusion of fruits and vegetables. In addition, the participants were also taught how to manage vegetable gardens for the cultivation of the food itself. The meetings lasted 8 hours a day, totaling 24 hours. The moment was ideal to provide training offered by an organic olericulture technician provided by the partner entity, who shared the knowledge in a practical way, where the participants could learn how to prepare the earth, to sow, to plant, to water, and to harvest. During the training, the nutritionist researcher also shared nutritional information. The encounters took place on consecutive days, during the morning and afternoon shifts. In view of what was experienced, the research proved to be useful for improving the participants' knowledge on the topic, promoting a critical reflection on food and nutritional security. It also emphasized the importance of cultivating the food itself to make it accessible.

ABSTRACT

The carbonized rice husk (CRH) is an agro-industrial residue with great potential for use in mixtures with other substrates for the production of vegetable seedlings. Thus, the purpose of this study was to evaluate the effect of the addition of CRH to the commercial substrate for the production of greenhouse seedlings. The evaluated vegetables were lettuce, broccoli and mustard, cultivated in polystyrene foam (Styrofoam®) trays. Five treatments were evaluated: 100% of the commercial substrate (CS); 25% of CRH + 75% of CS; 50% of CRH + 50% of CS; 75% CRH + 25% CS; and 100% CRH, in a completely randomized design with twelve replicates. The substrates were evaluated for their physical and chemical characteristics. The morphometric evaluations were: number of leaves per plant, plant height, shoot fresh matter yield, root length, and shoot and root dry matter yield. The data were submitted to regression analysis, and the homogeneity of the variance between the experiments was confirmed by the Cochran test. With the addition of CRH to the substrate, there was an increase in total porosity and P content and a reduction in density, water holding capacity, cation exchange capacity, electrical conductivity, and N, K, S, Ca and Mg contents. The carbonized rice husk added to the commercial substrate is a viable alternative for the production of lettuce, broccoli and mustard seedlings. The quality of the vegetable seedlings was higher when there was a 25% CRH + 75% CS mixture.

ABSTRACT

A significant level of yield losses in the vegetable and fruit farms are attributed to the weed populations of the area. This study was conducted for eighteen months during 2019-2020 to assess the presence of various weed families, related species, and their densities in the vegetable (CROP A) and fruit (CROP B) farms of Taif, Saudi Arabia. During the study, fourteen and ten weed families were noted in the vegetable and fruit farms of the studied area, respectively. Poaceae family weeds (729) were significantly higher in numbers followed by the families Asteraceae (414), Chenopodiaceae (338), and Gisekiaceae (153). In the vegetable farms, two weed species of the family Poaceae including Setaria viridis (437) and Eleusine indica ssp (277) were present in the higher numbers followed by Chenopodium murale (166) of the Chenopodiaceae family. In the fruit farms, the weed species Cynodon dactylon of the family Poaceae represented the highest weed density (172) followed by Gisekia pharnaceoides L. species (153) of family Gisekiaceae and Portulaca oleracea (59) belonging to the family Portulacaceae. The vegetable and fruit farms of the Taif region face severe weed pressure that affects the cultivated crops. This study depicts a comprehensive picture of weed diversity and density in the vegetable and fruit farms of the area. The results of this study will be beneficial in developing effective weed management practices for better crop production.


Um nível significativo de perdas de rendimento nas fazendas de hortaliças e frutas é atribuído às populações de ervas daninhas da área. Este estudo foi conduzido por dezoito meses durante 2019-2020 para avaliar a presença de várias famílias de ervas daninhas, espécies relacionadas e suas densidades nas fazendas de vegetais (CROP A) e frutas (CROP B) de Taif, Arábia Saudita. Durante o estudo, catorze e dez famílias de plantas daninhas foram observadas nas fazendas de hortaliças e frutas da área estudada, respectivamente. As plantas daninhas da família Poaceae (729) foram significativamente maiores em número, seguidas pelas famílias Asteraceae (414), Chenopodiaceae (338) e Gisekiaceae (153). Nas hortas, duas espécies de plantas daninhas da família Poaceae, incluindo Setaria viridis (437) e Eleusine indica ssp (277), estavam presentes em maior número, seguidas por Chenopodium murale (166) da família Chenopodiaceae. Nas fruticulturas, a espécie de plantas daninhas Cynodon dactylon da família Poaceae representou a maior densidade de plantas daninhas (172) seguida das espécies Gisekia pharnaceoides L. (153) da família Gisekiaceae e Portulaca oleracea (59) pertencentes à família Portulacaceae. As fazendas de hortaliças e frutas da região de Taif enfrentam uma forte pressão de ervas daninhas que afeta as culturas cultivadas. Este estudo apresenta um quadro abrangente da diversidade e densidade de plantas daninhas nas fazendas de hortaliças e frutas da região. Os resultados deste estudo serão benéficos no desenvolvimento de práticas eficazes de manejo de plantas daninhas para uma melhor produção das culturas.
