Dynamic Accumulation of Nutritional Elements in Garlic (Allium sativum L.) Cult...

Growth and yield traits of pickling cucumber plants to measure the impact of di...

Made available in DSpace on 2022-04-28T19:30:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Cucumber (Cucumis sativus L) is mostly cultivated by family-based farmers worldwide and processed to pickles by small to mid-sized industries generating employment and income. But irrigation management needs better investigation for adapting adequate sustainable practices. The rational use of irrigation...

Agronomic efficiency of liquid biofertilizers in potato cultivar Asterix

Made available in DSpace on 2022-04-29T08:27:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; The potato crop requires longer use of fertilizers, compared to all other cultures produced in Brazil. Therefore, it is important to conduct studies in, new sources that can enhance the balance between nutrients, improve soil's physical quality, provide nutrients based on the plant's needs and reduce en...

Genetic dissimilarity for thermoinhibition in seeds of lettuce lines after defo...

Removal of lettuce basal leaves is a technique used by the seed industry; however, the effects on seed production and physiological potential are unknown. Genetic dissimilarity is fundamental in the identification of individuals in terms of traits of interest, although it is rarely considered in relation to seeds that are tolerant to thermoinhibition. The aim of this study was to ascertain the relationship betw...

Productivity and quality of bagging fruit of hybrid tomatoes

Tomato cultivation is challenging due to the high susceptibility to various pests and diseases. Fruit borer insects make fruits unfeasible for commercialization because this favors colonization by pathogens. The loss due to borers can be avoided by bagging the bunches of fruit, helping the conventional crop to be more sustainable, reduce the use of pesticides, reduce the residue in fruits and improve the qualit...

Diversity of Pectobacterium strains by biochemical, physiological, and molecula...

Pectobacterium is a complex taxon of strains with diverse characteristics. It comprises several genera, including Erwinia, Brenneria, Pectobacterium, Dickeya, and Pantoea. Pectobacterium and Dickeya cause diseases in a wide range of plants, including potatoes, where they are causative agents of soft rot in tubers and blackleg in field-grown plants. Characterizing Pectobacterium species allows for the analysis o...

Challenges of organic agriculture for the production of composts and vermicompo...

Although the demand for organic fertilizers in agriculture is growing, it remains incipient in some production sectors, such as medicinal plant production, which does not possess specific technology for its development. Solid residues are highly contaminant to water sources, soil, populations and biodiversity but can potentially be used to produce organic composts and vermicompost, such production not only enab...

Seed potato minitubers production in a reused substrate

Minituber production is an important step to obtain high-quality seed potatoes. This production is carried out in a greenhouse using a large volume of commercial substrate acquired in specialized trade. An alternative to reduce the volume of substrate purchased for each production of minitubers would be to reuse it, which would be a way to optimize its use. The objective of this study was to evaluate the effici...

Economic study of the cultivation of kale, coriander, lettuce, and chives in in...

Intercropping of vegetables in a poorly planned manner may not achieve the expected economic results, as it is an activity that requires a great technical and administrative capacity of the producer. This study aimed to analyze the economic feasibility of intercropping kale with coriander, lettuce, and chives in relation to monocultures. The experiment was conducted in the Center for Agri-food Science and Techn...

Cytogenotoxic effects of nitrogen on hydroponic lettuce

Nitrogen accumulation in hydroponically-grown lettuce may pose a health risk to consumers. Thus, the objective of this study was to analyze different concentrations of nitrogen applications in hydroponic lettuce cultivation and their effect on toxicity, cytotoxicity and genotoxicity. A nutrient film technique (NFT) hydroponic system was used to grow the lettuce variety “Vanda.” The treatments consisted of diffe...
