“…Pata-de-vaca seedlings (Bauhinia forficata Link), a pioneer species naturally occurring throughout Brazil, presented higher shoot dry mass when concentrations of 200 mg dm -3 P 2 O 5 and 75 mg dm -3 N were applied ( RAMOS et al, 2000). The maximum shoot dry mass value (7.14 g) in the initial growth of Stryphnodendron polyphylum (barbatimão) was found at concentrations of 62.46 mg kg -1 N and 125.16 mg kg -1 P 2 O 5 (SOUZA et al, 2014), concentrations below those found in this work for the production of barueiro seedlings, indicating the importance of the association between nutrients (N and P) to provide greater growth of native species seedlings. Figure 4 shows that when nitrogen was applied, the fresh root mass of barueiro seedlings showed linear growth, with increment of 0.005 g of fresh root mass for each mg P 2 O 5 added to the soil.…”

Barueiro (Dipteryx alata Vog.), a fruit tree native to the Brazilian cerrado, has aroused the interest of producers and consumers due to its almond highly appraised and valued by local markets. To obtain quality barueiro seedlings, balanced fertilization is required, with special attention to the supply of phosphorus and nitrogen, essential for seedling growth and establishment in the field. The aim of this study was to evaluate the growth of barueiro seedlings produced with different phosphate and nitrogen concentrations in Nova Xavantina – MT. The experiment was conducted at the seedling nursery of the Mato Grosso State University (UNEMAT), Campus of Nova Xavantina - MT, from December 2017 to April 2018. The experimental design was randomized blocks (DBC), in a 5 × 2 factorial scheme, corresponding to 5 phosphorus concentrations and 2 nitrogen concentrations, with 10 treatments, 4 blocks and 10 plants per plot, totalizing 400 seedlings. The applied concentrations were 0, 150, 300, 450 and 600 mg kg-1 P2O5 and 0 and 250 mg kg-1 N. The following variables were evaluated: plant height, plant stem diameter, number of leaves, number of leaflets, fresh and shoot and root dry mass and Dickson’s Quality Index. Significant interaction between phosphorus and nitrogen concentrations for all traits evaluated was observed, except for root dry mass. The greatest growth of barueiro seedlings was obtained when the highest phosphorus concentration (600 mg kg-1de P2O5) was used, associated to nitrogen fertilization of 250 mg kg-1. There was no isolated effect of phosphate fertilization on the growth of barueiro seedlings without nitrogen application.

“…O teor de P foi maior nos tratamentos adubação + calagem, seguido de adubação + calagem + hidrogel e adubação + hidrogel, não sendo observada diferença significativa entre eles. Devido ao fósforo ser um nutriente fortemente adsorvido aos óxidos de ferro e alumínio (Souza et al, 2014), a utilização da calagem pode ser muito benéfica, pois além de elevar os teores de Ca e Mg e reduzir os teores solúveis de Fe e Al do solo, também aumenta a concentração de P lábil na solução do solo, tornando-o disponível para as plantas (Silva et al, 2007). Hidrogel, calagem e As menores concentrações de P nos tratamentos controle e hidrogel são justificáveis pela ausência de adubação e calagem, mantendo-se baixa a concentração deste elemento no solo.…”

“…Os solos brasileiros são, em sua maioria, antigos e altamente intemperizados, ácidos e com baixa disponibilidade de nutrientes, especialmente os do Cerrado, o que torna necessária a correção e adubação para níveis adequados ao desenvolvimento das plantas (Souza et al, 2014). Nesse ecossistema, o desenvolvimento das raízes é abreviado pelo excesso de alumínio trocável e também pela deficiência de cálcio, limitando a absorção de água e nutrientes e, consequentemente, a redução da produtividade da madeira do eucalipto (Costa et al, 2014).…”

Hidrogel, calagem e adubação no desenvolvimento inicial, sobrevivência e composição nutricional de plantas híbridas de eucalipto

et al. 2016

Com a premissa de que a utilização de hidrogel associado à calagem e adubação em plantios de eucalipto aumenta a retenção de água e o teor de nutrientes no solo, objetivou-se avaliar a sobrevivência e o desenvolvimento inicial de clones híbridos de Eucalyptus grandis x Eucalyptus camaldulensis, em função da utilização de hidrogel, calagem e adubação. Em um Argissolo Vermelho, foram dispostos os tratamentos: 1) controle, 2) hidrogel, 3) adubação convencional, 4) adubação + calagem, 5) adubação + hidrogel e 6) adubação + calagem + hidrogel. Foi utilizado o delineamento em blocos casualizados, com seis repetições e seis plantas por parcela. Avaliou-se a sobrevivência, a altura, o diâmetro do caule, o teor de macronutrientes na parte aérea e atributos químicos do solo. O tratamento adubação + hidrogel proporcionou maior altura e diâmetro aos 240 dias após o transplante. Contudo, a sobrevivência foi maior no tratamento com adubação convencional. Os resultados indicam a viabilidade do uso de hidrogel. Porém, mais estudos devem ser realizados para comprovação de seus efeitos e recomendação de dosagens adequadas.Hydrogel, liming and fertilizing in early development, survival and nutritional composition of eucalyptus hybrid plantsWith the premise that use of hydrogel associated with liming and fertilization in eucalyptus plantations increases water retention and nutrient content in the soil, this work aimed to evaluate the survival and early development of the hybrid Eucalyptus grandis x Eucalyptus camaldulensis when using hydrogel, liming and fertilization. In Ultisol, the treatments were: 1) control, 2) hydrogel, 3) conventional fertilization, 4) fertilizer + lime, 5) fertilizer + hydrogel and 6) fertilizer + lime + hydrogel. The treatments were arranged in a randomized block design, with six replications and six plants per plot. We evaluated height, diameter, survival, macronutrient content in shoot and soil chemical properties. The hydrogel + fertilization treatment provided bigger height and diameter at 240 days after transplant, however, the survival was higher in fertilization treatment. The results indicate the viability of the hydrogel use. However but more studies are needed to prove its effects and recommendation of appropriate dosages.Index terms: Initial growth; Nutritional evaluation; Hidroretentor gel

“…According to Soares et al (2013), H. stigonocarpa is a typical species of acid soils and is not very demanding for nutrients to develop. Even considering that native Cerrado plants are adapted to low fertility soils, experimental fertilization studies indicate that woody species may respond to soil fertilization, especially when these nutrients are nitrogen and phosphorus (Scholz et al, 2007), since these are the most limiting nutrients for plant growth and development (Souza et al, 2014), acting in several important processes for the survival and growth of plants. For example, phosphorus acts in most metabolic processes of enzymes and participates in cell division, photosynthesis, and respiration (Shabnam & Iqbal, 2016).…”

Physiological and Morphological Behavior of Hymenaea stigonocarpa Seedlings Submitted to Phosphorus

et al. 2020

View full text Add to dashboard Cite

In face of the global situation, a practice which has been gaining strength is producing seedlings for environmental restoration. Among the species that stand out for such activity is Hymenaea stigonocarpa. However, little is known about their nutritional requirements. The objective of this study was to evaluate the morphophysiological behavior of H. stigonocarpa seedlings submitted to phosphorus doses. The design was completely randomized with five doses (0, 100, 200, 300 and 400 mg dm-³) and four replicates. Physiological, morphological, biomass and phosphorus content analyses were performed. There was a difference for root mass ratio, leaf mass ratio, shoot mass ratio, leaf area and root area. The dose of 200 mg dm-³ is recommended for H. stigonocarpa seedlings.
