Objetivou-se avaliar o crescimento e qualidade de mudas de Schizolobium amazonicum (Huber ex Ducke) sob tratamento pré-germinativo de semente e aplicação foliar de agentes químicos durante a formação. O experimento foi realizado realizados no laboratório de análises de sementes e casa de vegetação da Universidade Estadual de Mato Grosso do Sul/Unidade Universitária de Cassilândia-MS. Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial 2x3, sendo constituído por dois tratamentos pré-germinativos por hidratação das sementes (TS1 – água e TS2 – nitrato de cálcio 0,2%) e três agentes químicos fornecidos via foliar (TF1 – testemunha sem tratamento, TF2 – Bioestimulante composto por giberelina 0,1% + auxina 0,2% + nitrato de cálcio 0,2% e TF3 – mistura contendo paclobutrazol 0,01% + uréia 0,2%) com 10 repetições por tratamento e 6 plantas por repetição. Aos 45 dias foi realizada as primeiras medições e a avaliação final foi realizada aos 60 dias (período de plantio das mudas no campo). O tratamento de sementes com nitrato de cálcio produziu mudas com qualidade semelhante as mudas originadas de sementes que foram hidratadas somente com água. O uso de paclobutrazol e nitrogênio na aplicação foliar resultou em mudas de eleva a qualidade de Schizolobium amazonicum.

“…Plant development phase can also influence the soil correction response. Vargas & Marques (2017) assessed the effect of liming on Anadanthera colubrina (angico) and Senna multijuga (canafístula) growth for 7 months in soil with 5% base saturation. The highest plant growth rate was recorded at 50% and 20% base saturation for angico and canafístula, respectively.…”

Growth and Quality of Leucochloron incuriale Seedlings Subjected to Liming and Phosphorus

2019

Leucochloron incuriale can be used in projects to restore degraded areas and for logging purpose. Soil has been used in nurseries to produce seedlings; however, most soil types in Brazil have low nutrient availability and high acidity level. The aim of the current study is to assess the effect of liming and phosphate fertilization on the growth and quality of Leucochloron incuriale seedlings. Treatments were arranged in factorial design with five base saturation levels -3.5 (original), 25, 40, 55 and 70% -and six P levels -0, 120, 240, 360, 480 and 600 mg dm -3 -in completely randomized blocks with four repetitions. The morphological features and their relations were assessed 82 days after planting. Phosphorus levels had significant effect on most of the assessed traits. The recommended P dose was 475 mg dm -3 .

“…The results regarding Ca were explained due to the initial available contents in the soil, where the Arenosol showed high Ca content and the Alisol low content. Vargas & Marques (2017), studying the nutrition of leguminous trees, observed no response in macronutrient leaf contents after limestone and gypsum application, except for K content with gypsum that was higher when compared to the control and limestone treatments, which was explained by the lower growth of the plants. According to these authors, the absence of response regarding Ca content may be related to the effect of the previous soil acidity correction that overcome Ca deficiency.…”

The high demand for forest products in Brazil estimates a 2 million hectares increase in reforestation areas over the next 10 years, highlighting Eucalyptus species. However, these crops usually occur in acid soils that need correction to achieve high productivity. Besides limestone, lime mud, a residue from the cellulose industry, and gypsum can also be used as correctives, but there are doubts about doses and ways of application with the best results. Thus, were evaluated the soil chemical attributes, foliar nutrient content, and initial growth of a Eucalyptus dunnii Maiden crop in response to the application of limestone, lime mud, and gypsum in different doses and ways of applications, on a Humic Cambisol from Santa Catarina Plateau. The experiment was carried out with nine treatments in four replicates, where the evaluated parameters were determined up to 24 months after planting. In general, both limestone, lime mud, and gypsum, in different doses and ways of application, affected the chemical attributes of the soil but did not affect the foliar nutrient content at 12 months, height, and diameter at breast high (DBH) from trees and timber volume at 24 months. Gypsum do not correct soil acidity but lime mud provides similar results to limestone indicating that can substitute this corrective without damage to nutritional status and initial development of Eucalyptus dunnii.
