Microgreens são plantas jovens de hortaliças colhidas prematuramente que vêm ganhando popularidade na culinária convencional e gourmet devido às suas propriedades nutricionais e sensoriais. Este estudo teve como objetivo avaliar a aceitabilidade de microgreens de alface (Lactuca sativa L.), agrião-do-seco (Lepidium sativum L.), amaranto (Amaranthus caudatus L.), beterraba (Beta vulgaris L.), couve (Brassica oleracea L.) e girassol (Helianthus annuus L.) pelos hóspedes do Lapinha SPA, um estabelecimento de revigoramento da saúde física e mental localizado no município de Lapa, estado do Paraná. Para avaliar a aceitabilidade desses vegetais foi utilizado a metodologia de resto-ingesta. Os resultados obtidos mostraram que a aceitabilidade das espécies variou entre 84,84% e 96,60%, sendo considerada ótima para todas as espécies ofertadas. A análise de variância seguida pelo teste de Tukey mostrou que houve diferença estatisticamente significante no índice de aceitabilidade, sendo que as espécies mais bem aceitas em ordem decrescente, foram os microgreens de amaranto (sobra média = 2,16 g), couve (sobra-média = 5,12 g), agrião-do-seco (sobra-média = 6,40 g), alface (sobra-média = 6,60 g), beterraba (sobra-média = 6,84 g), e girassol (sobra-média = 9,76 g). Essas plantas apresentam potencial para serem incorporados à dieta de clientes de estabelecimentos SPA’s, uma vez que agregam valor nutricional e estético diferenciados aos pratos ofertados na culinária.

Lepidium Sativum L

Organic biodegradable waste composes a fair part of farm and vital activity waste. The disposal of this waste in municipal waste landfills pollutes the environment and soil. Therefore, the European Union and other countries look for alternatives to manage biodegraded waste. This paper seeks to analyse the properties of sludge that forms in the sewage treatment plants of the acid casein production, examines experience in managing and applying sludge. The results of an experiment show that sewage sludge from the acid casein production is suitable as a soil fertilizer for growing lettuce (Lactuca sativa L.) and garden cress (Lepidium sativum L.). After soil was fertilized with this sludge, the germination of lettuce and garden cress as well as the biomass of experimental alimentary plants increased. A suitable ratio of soil and sludge mixture was determined (for lettuce ‐ 1:1, for garden cress ‐ 3:1). Potassium sulphate which was added to a soil‐sludge mixture improved the values of fertility parameters of alimentary plants.

Lepidium Sativum L

Metasequoia glyptostroboides Hu et W.C. Cheng is one of the oldest living conifer species, and it has remained unchanged for millions of years compared to its fossils from the Cretaceous period. The species are cultivated in the parks, gardens, and roadsides in many countries. We investigated the allelopathy and allelopathic substances in fallen leaves of M. glyptostroboides. An aqueous methanol extract of the fallen leaves inhibited the growth of cress (Lepidium sativum L.), lettuce (Lactuca sativa L.), alfalfa (Medicago sativa L.), Lolium multiflorum Lam., Phleum pretense L., and Vulpia myuros (L.) C.C.Gmel. The extract was then purified by several chromatographic steps, and two allelopathic substances were isolated and determined by spectral data to be (+)-rhododendrol and 9-epi-blumenol C. The compound inhibited the growth of cress and L. multiflorum. M. glyptostroboides is a deciduous perennial tree, and accumulation of its fallen leaves occur on the soil under the trees. Therefore, those allelopathic substances in the fallen leaves may be liberated into the rhizosphere soil during the decomposition process of fallen leaves and provide a competitive advantage for M. glyptostrob through the growth inhibition of competing plant species nearby. Therefore, M. glyptostroboides is allelopathic, and (+)-rhododendrol and 9-epi-blumenol C may be contribute to the allelopathy.

Organic farming systems are considered not compatible with conservation tillage mainly because of the reliance of conservative systems on herbicides. In this three-year field experiment, we tested the performances of an innovative vegetable organic and conservative system (ORG+) combining the use of cover crops (exploited as either living or dead mulch) and no-till techniques. This system was compared to “business-as-usual” organic farming (ORG) and integrated farming system (INT) based on the same crop sequence: savoy cabbage (Brassica oleracea var. sabauda L. cv. Famosa), spring lettuce (Lactuca sativa L. cv. Justine), fennel (Foeniculum vulgare Mill. Cv. Montebianco), and summer lettuce (Lactuca sativa L. cv. Ballerina RZ). The results of crop yield parameters and weed abundance contribute to spotlight potentialities and weaknesses of organic-conservative management of field vegetables. In particular, ORG+ caused significant yield depletion for all the crops and revealed suboptimal weed control and N availability. The agroecosystem services provided by the cover crops grown in the ORG+ as dead mulch or living mulch were affected by weather conditions and not always resulted in significant crop gain. Nevertheless, interesting results in terms of P availability and reduced N surplus encourage further development of the system targeting more sustainable organic vegetable production.

The Impact

Vegetable transplanting is an important and advantageous practice in vegetables production systems. In recent years, the development of vegetable transplanting tools has increased, as well as the interest for automatic and robotic transplanters. However, at present, the feeding of transplanting machines is often still performed by hand. This paper presents the design, development and testing of a needle gripper and a two-finger gripper for vegetable transplanting. Both grippers were self-designed and tested for picking, lifting and transplanting plug seedlings. Tests have been conducted on fennel (Foeniculum vulgare L.), leek (Allium ampeloprasum L.) chicory (Cichorium intybus L.) and lettuce (Lactuca sativa L.) seedlings to determine the impact that gripper typology might have on the further growth of plants after transplanting. The average success rate of the two-finger gripper in the transplanting experiment was 95% and of the needle gripper 81.75%, respectively. Although neither gripper typology affected the growth of the seedlings after transplanting, several design implications were identified in order to improve the performance of both grippers. Furthermore, the two-finger gripper is more reliable for lettuce and chicory, while the needle gripper requires root plugs with higher firmness and cohesion to prevent shattering.
