De Souza, Bruno Uehara; Oliveira, Roberta Camargos; Luz, José Magno Queiroz; Machado, Daniel Lucas Magalhães; Aguilar, Ariel Santivañez [UNESP]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...
Challenges of organic agriculture for the production of composts and vermicompo...
Pereira , Maysa Mathias Alves; Morais, Ludmila Caproni; Martins, Adalvan Daniel; Luz, José Magno Queiroz; Pasqual, Moacir; Oliveira, Roberta CamargosAlthough 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...
Sources of potassium in the fertilization of Agata potato
Oliveira, Roberta Camargos; Luz, José Magno Queiroz; Cardoso, Rodrigo Ribeiro; Lana, Regina Maria Quintão; Silva, Jarbas dos ReisThe potato plant presents extraordinary productive capacity, being the fertilization one of the essential factors to optimize the cultivars potential. Potassium (K), the nutrient most absorbed and transported by the crop, interferes with the productivity and tubers quality. Despite many efforts to improve the general and nutritional management of the crop, information as K source and its parceling are still not...
Fertilization and cropping systems: performance and oil content of basil varieties
Silva, Adeláide Siqueira; Oliveira, Roberta Camargos; Luz, José Magno Queiroz; Silva, Sérgio Macedo; Blank, Arie Fitzgerald; Alves, Mércia FreitasSweet basil (Ocimum basilicum L.) is an aromatic and medicinal crop that produces metabolites rich in chemical constituents for various purposes. The composition of the essential oil is variable due to external factors during production, such as fertilization and the environment, and the oil concentration may vary even among the genotypes of a species. For sweet basil mores studies are needed to clarify underst...
