- Abstract
Phosphorus is a major limiting nutrient for crops in tropical regions. In addition, another major challenge for the future agriculture will be to maintain water levels in the soil to ensure satisfactory crop development. This study inserted in this context aimed to evaluate the conditioning caused by phosphorus fertilization and water availability in the soil over the biomass production and nutritional efficiency of plants of crambe (Crambe abyssinica Hochst). To this end, the experiment was conducted in a greenhouse, with four levels of phosphorus fertilization and three levels of water availability, along of 45 days, in order to obtain information about the production of biomass, nutritional contents, and the patterns of the nutritional efficiency of crambe plants. The results show that increasing the phosphorus supply in the soil promotes greater biomass production in crambe plants. In addition, the increase in water availability and levels of phosphorus fertilization near the recommended level promotes greater nutritional efficiencies in absorb, translocate and use the phosphorus available in the soil., La disponibilidad de agua y fósforo es una limitante para los cultivos en las regiones tropicales. El objetivo de este estudio fue evaluar el efecto de la fertilización fosfatada y la disponibilidad de agua en el suelo sobre la producción de biomasa y la eficiencia nutricional de las plantas de crambe (Crambe abyssinica Hochst). Las plantas fueron cultivadas en un invernadero, con cuatro niveles de fertilización de fósforo y tres niveles de disponibilidad de agua, para estudiar el comportamiento vegetativo entre emergencia y floración. Se evaluó la biomasa, contenido nutricional y patrones de eficiencia nutricional de las plantas. Los resultados muestran un aumento de biomasa al fertilizar con fósforo. Se observa un efecto sinérgico al aumentar la disponibilidad de agua y fósforo, mejorando la eficiencia en la absorción del fósforo disponible en el suelo.

Objective: To evaluate the efficacy of desensitizing agents for the obliteration of dentinal tubules subjected or not to a simulated oral environment. Material and Methods: Dentinal discs (n=8) treated with Riva- Star (RS) or PRG-Barrier-Coat (PRG) were submitted (cycled) or not submitted (control) to erosiveabrasive- thermal cycles and evaluated using scanning electron microscopy/energy dispersive spectroscopic analysis. The variables analyzed were tubule obliteration and dentin surface chemical composition. Data were analyzed by non-parametric tests (p<0.05). Results: The cycled and control groups did not differ significantly for the responses in each material. The PRG control and cycled groups had fewer visible tubules and a higher proportion of totally obliterated tubules than the RS groups. The percentages of silver coverage were higher in the RS-control than in the RS-cycled. There was a significant inverse correlation between the presence of silver and non-obliterated tubules (R=-0.791; p<0.001). The percentages of carbon, aluminum, strontium, and potassium were significantly higher in the PRG-control and PRG-cycled compared to the RS control. The percentages of calcium, phosphorus, and silver were significantly higher in the RS compared to the PRG groups. PRG-control showed a higher percentage of boron than RS-control. Conclusion: PRG promoted greater tubule obliteration than SR. Simulated stress did not affect the obliterating effect of each agent. Greater silver coverage corresponded to a lower proportion of nonobliterated tubules in RS. Carbon, aluminum, strontium, boron, and potassium predominated in the dentin surface treated with PRG, while calcium, phosphorus, and silver prevailed in RS groups. [ABSTRACT FROM AUTHOR]

The variability of growth patterns and capacity to resist to environmental stresses that exists in populations of Coffea canephora Pierre ex Froehner makes it possible to select genotypes for different types of cultivation conditions. The objective of this study was to evaluate the monthly growth rate as a criterion to measure the genetic diversity of genotypes and to estimate the direct and indirect effects of the monthly growth rate, by path analysis, over the length of orthotropic stems. The experiment followed a randomized complete block design, studying 10 genotypes of C. canephora Pierre ex A. Froehner, with four replications and six plants per experimental plot. The magnitudes of the direct and indirect effects observed in the path analysis are consistent indicatives that the growth rate during recovery months, in the peaks after periods of slower growth, is highly important to determine the length of the stems during the final of the season. There is a considerable level of similarity between the growth of genotypes from the same group regarding ripening cycle; however, the high variability makes possible to identify genotypes from different behaviors regardless of the group. Key words: Conilon coffee, orthotropic stems, genetic parameters, variability.

The objective of this study was to quantify the nutritional efficiency and responsiveness in relation to nitrogen of twelve genotypes of physic nut (Jatropha curcas L.) grown in soil without nitrogen supply and also with three levels of fertilization in a controlled environment. The experiment was conducted in factorial scheme 12 × 4 with four replications, the factors being: 12 genotypes of physic nut and four levels of nitrogen fertilization, studied in a randomized design. The plants were grown in pots, without restrictions, for 100 days and their dry matter and N contents were evaluated (for roots, leaves and total). Subsequently, the efficiency ratios for absorption, translocation, use and responsiveness in relation to the N supply were calculated. Overall, the nutritional efficiencies for nitrogen increase linearly with the increase of nitrogen supply in the soil. The genotypes CNPAE 161-II, CNPAE 167-II, CNPAE 180-I, CNPAE 255-I and CNPAE 300-I were classified as efficient and responsive to nitrogen fertilization being highlighted for plant breeding programs aiming to improve this agronomic trait. Key words: Physic nut, mineral nutrition, alpha parameter.

Crambe is a sensitive specie to exchangeable aluminum, it require a well-fertilized and corrected soil. The objective of this study was to understand the impact of aluminum presence, in different concentrations, in the substrate on the germination and development of crambe. The experiment was carried out as a randomized complete block design with a 5x2 factorial arrangement in four replicates. The five concentrations of Al3+ were 0, 15, 40, 80 and 120 mg dm-3 Al3+ and two temperatures (20 and 30 °C), with four replications. The relative growth rate, plant height, leaf number, total leaf area, specific leaf area, dry matter in each plant compartment (root, stem and leaf), leaf area ratio, stem mass ratio and leaf mass ratio were evaluate. Germination was favored by 20 ºC. The limitation on plant growth was greater as the concentration of aluminum increased, presenting losses in growth, as well of production of dry matter and leaf development, also causing changes in the patterns of biomass allocation between the plant compartments. Crambe es una especie sensible al aluminio intercambiable que requiere suelos bien fertilizados y corregidos. El objetivo de este trabajo fue evaluar distintas concentraciones de aluminio en la germinación y desarrollo de crambe. El experimento para germinación se realizó con un diseño de bloques completos al azar con arreglo factorial de 5x2, con cuatro repeticiones. Las cinco concentraciones de Al3+ fueron 0, 15, 40, 80 y 120 mg dm-3 y las temperaturas de 20 y 30° C. El experimento para desarrollo de la planta se realizó con un diseño de bloques completos al azar con cinco concentraciones de Al3+ y cuatro repeticiones. Los parámetros evaluados fueron porcentaje de germinación, crecimiento de las plántulas y biomasa. Se analizó la tasa relativa de crecimiento, altura de planta, número de hojas, área foliar total, área foliar específica, materia seca en cada compartimento de la planta (raíz, tallo y hojas), razón de área foliar, razón de masa de raíz, tallo y hojas. El porcentaje de germinación aumentó a los 2 °C. La mayor concentración de aluminio afectó el crecimiento, producción de materia seca y desarrollo de hojas. Estos resultados sugieren que el cramble es sensible al aluminio intercambiable.

- Abstract
Castor bean plant (Ricinus communis L.) is a demanding plant about nutrients, its fertilization is still little studied in Brazil. The cultivation of castor bean plant exports from the area about 80 kg ha-1 N, 18 kg ha-1 of P2O5 and 32 kg K2O ha-1 for every 2.000 kg ha-1 of produced soft. This study evaluated the effect of different sources of fertilizer (mineral, cattle manure, poultry manure and coffee straw) on the growth rate of castor bean plant. The experiment was conducted in a greenhouse at the Centro de Ciências Agrárias da Universidade Federal do Espírito Santo (CCA/UFES) following a completely randomized design with split plot in time. The castor bean was grown for 84 days (12 weeks) and the growth parameters of plants were evaluated. The results show that the castor bean plant showed higher growth when subjected to organic fertilization with poultry manure, reaching the highest averages for all variables, exceeding the average mineral fertilizer at the end of the evaluation period., A mamoneira (Ricinus communis L.) é uma planta exigente em nutrientes, sua adubação ainda é pouco estudada no Brasil. O cultivo da mamona exporta da área cerca de 80 kg ha-1 de N, 18 kg ha-1 de P2O5 e 32 kg ha-1 de K2O para cada 2.000 kg ha-1 de baga produzida. Este trabalho buscou avaliar o efeito de diferentes fontes de adubo (mineral, esterco bovino, cama aviária e palha de café) na taxa de crescimento da mamoneira. O experimento foi desenvolvido em casa de vegetação no Centro de Ciências Agrárias da Universidade Federal do Espírito Santo (CCA/UFES), seguindo delineamento inteiramente ao acaso, com esquema de parcelas subdivididas no tempo. A mamona foi cultivada e avaliada durante 84 dias (12 semanas), quanto a parâmetros de crescimento das plantas. Os resultados mostram que a mamoneira apresentou maior crescimento quando submetida à adubação orgânica com cama aviária, atingindo as maiores médias para todas as variáveis estudadas, superando as médias da adubação mineral ao fim do período de avaliação.

- Abstract
The castor oil plant (Ricinus communis L.) is a demanding plant in essential nutrients, yet fertilizing is still very little studied in Brazil. The cultivation of castor oil plant exports from the field about 80 kg ha-1 of N, 18 kg ha-1 of P2O5 and 32 kg ha-1 of K2O for each 2,000 kg ha-1 of produced berry. The cultivar IAC 226 assembles plants of middle-high height, with low ramification, several middle size racemes, and able to have up to 18 effective racemes, resulting in high productivity. The aim of this study was to evaluate the growth in the early development of the cultivar IAC 226 for the castor oil plant, in two soil textures, very clayey and middle, and with five different levels of NPK fertilization, 0, 100, 200, 400 e 800% of the recommended dose. The experiment was conducted in randomized design, using plastic containers in the green house, located in the campus of the Centro de Ciências Agrárias of UFES. The results show that the culture responds positively to increasing levels of NPK, reaching higher values of dry matter, leaf area, number of leaves and stem diameter for levels until 800% of the actual recommended dose for the Espírito Santo state. These results of the fertilizer addition were more pronounced in the middle texture soil, with evidence of its lower buffer power, when compared to the clayey soil., A mamoneira (Ricinus communis L.) é uma planta exigente em nutrientes essenciais, sua adubação ainda é pouco estudada no Brasil. O cultivo da mamona exporta da área, cerca de 80 kg ha-1 de N, 18 kg ha-1 de P2O5 e 32 kg ha-1 de K2O para cada 2.000 kg ha-1 de baga produzida. A cultivar IAC 226 reúne plantas de porte médio-alto, com ramificação baixa, com diversos racemos de tamanho médio, podendo ter até 18 racemos efetivos, traduzindo-se em alta produtividade média. O objetivo deste trabalho foi avaliar o crescimento no período inicial de desenvolvimento do cultivar IAC 226 de mamona em duas texturas de solo, muito argilosa e média, e com cinco diferentes níveis de NPK, 0, 100, 200, 400 e 800% da dose recomendada. O experimento foi conduzido em delineamento inteiramente casualizado, usando vasos plásticos, em casa de vegetação, localizada no campus do Centro de Ciências Agrárias da UFES. Os resultados obtidos mostram que a cultura responde positivamente a doses crescentes de NPK, atingindo maiores valores de matéria seca, área foliar, número de folhas e diâmetro do caule para níveis de até 800% da dose atualmente recomendada para o Estado do Espírito Santo. Os resultados da adição dos fertilizantes foram mais pronunciados no solo de textura média, prova do seu menor poder tampão, quando comparado ao solo muito argiloso.

- Abstract
The castor bean plant (Ricinus communis L.) is an exigent plant in nutrients and is sensitive to soil acidity, presenting good response in productivity to the correction of soil and the manure. This study evaluated the effect of different manures (mineral, cattle manure, poultry manure and coffee straw) in the absence and presence of the application of siderurgy scoria as corrective of soil acidity, in the production of fresh matter and dry matter of the aerial part and root, and aerial part/root relation of castor bean plants. The experiment was developed in greenhouse in the Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo (CCA/UFES), following a randomized blocks design, 2x4 factorial scheme, with the presence or absence of correction of soil acidity with siderurgy scoria associated to 4 types of fertilizer. The castor bean plant was cultivated during 12 weeks, when the plants were cut to make the evaluations of production of fresh and dry matter of aerial part and root. The results show that the castor bean plant is responsive to organic manure and that the use of poultry manure, as well as the use of siderurgy scoria as acidity corrective, gave the best results for the production of biomass of castor bean plants., A mamoneira (Ricinus communis L.) é uma planta exigente em nutrientes e sensível a acidez do solo, apresentando boa resposta em produtividade à correção do solo e à adubação.
