Abstract
In the process of seedling production plant nutrition can improve the quality. Among the forest species, the teak stands out for the resistant wood and its rusticity. The knowledge of the nutritional needs of teak seedlings favors its development with reflex in the field production. The experiment was conducted in a greenhouse with seedlings planted in 3 liter pots, as substrate we used underground soil. The treatments were divided into: control, complete solution; omission of N, omission of P, omission of K, omission of Ca, omission of Mg, omission of Si. To evaluate the effects of treatments on plants, we measured total height and stem diameter, with six biweekly readings. The observations were submitted to analysis of variance and the means were compared by Tukey test at 5% probability. Subsequently, linear regression models were adjusted, containing as independent variable: development time; and variable dependent height and diameter of the collection per treatment. There was no significant difference between treatments in the variable total height of plants, only in stem diameter where the complete treatment had the highest mean values. In the first months of development of teak, it was possible to observe a sufficient performance in the evaluated variables, however, fertilization should be carried out for a satisfactory production, mainly containing the macronutrients N, P, K.
Highlights
The nutricional deficiency or imbalance is common among plants, because they do not always find the necessary elements, much less, in the adequate concentrations (LARA, 1991), the lack or excess of the available elements results in malfunctions that compromise mainly its rate of growth (CRUZ et al, 2012)
The handling of the forest nutrition is determining in the productivity management, the availiability of nutrients must be modified by the forest managers according the necessity of the cultivation (MOYA et al, 2014a)
The process of forestry seedling production requires studies that aim to improve its efficiency (STORCK et al, 2015), in which morphological characteristics are used more frequently in the determination of the quality, and those are influenced by environment and maintenance of fertility in the utilized substrate
Summary
The nutricional deficiency or imbalance is common among plants, because they do not always find the necessary elements, much less, in the adequate concentrations (LARA, 1991), the lack or excess of the available elements results in malfunctions that compromise mainly its rate of growth (CRUZ et al, 2012). The handling of the forest nutrition is determining in the productivity management, the availiability of nutrients must be modified by the forest managers according the necessity of the cultivation (MOYA et al, 2014a). The process of forestry seedling production requires studies that aim to improve its efficiency (STORCK et al, 2015), in which morphological characteristics are used more frequently in the determination of the quality, and those are influenced by environment and maintenance of fertility in the utilized substrate The fertilisation of the substrate is important to favour the growth and quality of plants, respecting traits such as quality of the nutrients, type of subtrate and the species used to obtain the best possible development (NAVROSKI et al, 2016)
