Effect of potassium fertilization on yield and nutrition of yerba mate (Ilex pa...
Santin, Delmar; Benedetti, Eliziane Luiza; Barros, Nairam Félix de; Almeida, Igor Carvalho de; Leal, Greice Pereira; Fontes, LucasA erva-mate (Ilex paraguariensis), espécie arbórea nativa das regiões subtropicais da América do Sul, ocorre no Brasil predominantemente na Região Sul. Apesar da histórica importância da cultura nessa região, até o momento, raros foram os trabalhos realizados sobre sua nutrição no intuito de melhorar a produtividade. Assim, objetivou-se avaliar a influência de doses de K e sua disponibilidade no solo, na produt...
Mineral content of young leaves of yerba mate
Bastos, Marília Camotti; Reissmann, Carlos Bruno; Keseker, Jéssica Fernandes; Pauletti, Volnei; Gaiad, Sérgio; Sturion, José AlfredoYerba mate is largely used to produce drinks to human consume. In Spring the plants develop tender young leaves that could represent a new market niche in the yerba-mate industry; this period is called as ”pressafrinha” in this study. This study aimed to analyze the total and hydro soluble nutritional values of young leaves collected in the Spring season and its nutritional potential for human consumption. To r...
Development and Nutrition of Ocotea odorifera (canela sassafrás) Submitted to t...
Keil, Silvia Schmidlin; Reissmann, Carlos Bruno; Pellico Netto, SylvioThe present paper has as objective the evaluation of the nutritional aspects, fertilization effect and omission of nutrients in the plants grow of canela sassafras (Ocotea odorifera (Vell.) Rohwer), in a vegetation house for 24 months, consisting of 11 treatments and five repetitions, with seasonal collections, using the springer material. The treatments consisted of control (natural soil), complete fertilizati...
Micronutrient Modeling for Mimosa scabrella Bentham in the Curitiba Metropolita...
Téo, Saulo Jorge; Machado, Sebastião do Amaral; Figueiredo Filho, Afonso; Reissmann, Carlos BrunoThe objective of this research was to model the micronutrient content for Mimosa scabrella Benthamabove-ground biomass, aiming to obtain equations to estimate micronutrient content using tree dimensions asindependent variables. Data came from 25 trees sampled in native Mimosa scabrella stands in the northernCuritiba metropolitan region, Parana state, Brazil. The trees were cut down and their components were sep...
Pruning and bark girdling or erva-mate (Ilex paraguariensis) aiming induction o...
Santin, Delmar; Wendling, Ivar; Benedetti, Eliziane Luiza; Brondani, Gilvano Ebling; Reissmann, Carlos Bruno; Morandi, Divercindo; Roveda, Luís FernandoThe extrativism method, inappropriate management and the reduction of mate tree populations has resulted in the loss potencial of relevant specimens for future genetic improvement. Few are the techniques and studies, focused on the restoration of degraded mate tree plantations, in order to recover vegetative samples of mature trees. So, an experiment was installed in São Mateus Country, Paraná State-BR, in a ma...
