Boron supplementation in barley sowing and tillering
Tavares, Lizandro Ciciliano; Lemes, Elisa Souza; Brunes, André Pich; Oliveira, Sandro de; Mendonça, André Oliveira de; Villela, Francisco AmaralBoron is required in small amounts by crops and the decision to apply adequate soil intakes is vital to increase crop productivity. This study aimed to evaluate the influence of supplementation with boron at sowing and tillering on the agronomic characteristics and physiological quality of barley seeds. The experimental design was completely randomized in a factorial design (Factor A: application at sowing and ...
Initial growth and sodium content in rice plants under salinity
Lemes, Elisa Souza; Oliveira, Sandro de; Neves, Edinilson Henrique das; Ritter, Ronan; Mendonça, André Oliveira de; Meneghello, Geri EduardoGrowth analysis is an affordable, cheap, and accurate method to evaluate plant growth against different environmental and management conditions. In this sense, this study aimed to evaluate the effect of salinity on the initial growth and sodium accumulation in the plant tissue of two rice cultivars. The experimental model used was a completely randomized design, constituting a 2 x 2 factorial (BRS Bojuru and IR...

Anthracnose severity in common bacterial blight in bean under different spacing...
Schuch, Luis Osmar Braga; Antunes, Irajá Ferreira; Ludwig, Marcos Paulo; Oliveira, Sandro de; Lemes, Elisa SouzaThe beans (Phaseolus vulgaris L.) has great economic and social importance in Brazil as part of the basic food. The incidence of leaf diseases cause damage to crops. The objective was to evaluate the severity of Anthracnose and Bacterial blight common in bean under different spacing and plant populations. The experiments were conducted in the experimental area of Agricultural Center of Palma, the Federal Univer...
Morphophysiological performance of medium cycle soybean cultivars under flooding
Ludwig, Marcos Paulo; Oliveira, Sandro de; Schuch, Luis Osmar Braga; Vernetti Junior, Francisco Jesus; Seus, Rogério; Lemes, Elisa SouzaThe increase in soybean cultivation in Brazil has reached areas previously used for other purposes, such as in regions of lowland soils, thus being subject to possible soil flooding. This study aimed to evaluate morphophysiological changes in medium cycle soybean cultivars, under soil flooding conditions, in the vegetative and reproductive stages to recommend cultivars. The experiments were conducted at the Est...
Suplementação de boro em diferentes épocas: Efeito no rendimento e na qualidade...
Brunes, Andre Pich; Lemes, Elisa Souza; Mendonça, André Oliveira de; Oliveira, Sandro de; Villela, Francisco AmaralO objetivo do trabalho foi avaliar a influência da aplicação de boro em diferentes épocas no rendimento e na qualidade de sementes de trigo. O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial A X B, sendo o fator A: cultivares FUNDACEP Horizonte e BRS Campeiro, e fator B: época de aplicação, (Sem aplicação de boro, aplicação na semeadura, no perfilhamento, na floração e 15 di...
Physiological potential of irrigated rice seeds treated with amino acids and un...
Lemes, Elisa Souza; Dias, Leticia; Rosa, Thais D'Avila; Gehling, Vânia Marques; Oliveira, Sandro de; Mendonça, André Oliveira deSalt stress in rice plants affects growth, development and crop yield. However, seed treatment can reduce the deleterious effects caused by salt stress. The use of amino acids in agriculture has increased, both in Brazil and in other countries, due to higher productivity and provide better quality of plants treated with amino acids. The objective of this study was to evaluate the effect of amino acid coating on...
Silicon application to the soil on soybean yield and seed physiological quality
Oliveira, Sandro de; Lemes, Elisa Souza; Meneghello, Géri Eduardo; Tavares, Lizandro Ciciliano; Barros, Antonio Carlos AlbuquerqueUse of quality seeds, balanced plant nutrition and the adoption of adequate cultivation techniques are critical to the success of the soybean crop. Use of silicon (Si) is a clean technology from an environmental point of view, which can confer several benefits to the plants as stimulate growth and plant production, improve tolerance of plants to attack by insects and diseases, reduce perspiration and increase t...
Amassamento durante o manejo do cultivo: efeito no rendimento e na qualidade de...
de Oliveira, Sandro; Ludwig, Marcos Paulo; Crizel, Renato Lopes; Lemes, Elisa Souza; Lucca Filho, Orlando AntonioCom o objetivo de avaliar a produção e a qualidade fisiológica de sementes de soja produzidas em diferentes linhas amassadas pelo rodado do trator durante as aplicações de agrotóxicos, foi realizado um experimento no município de Jari - RS, durante a safra 2008/2009. Foi determinada a altura das plantas ainda no campo e posteriormente foram coletadas cinco linhas localizadas em diferentes posições em relação ao...
Seed treatment of Avena sativa l. with zinc: physiological quality and performa...
Oliveira, Sandro de; Tavares, Lizandro Ciciliano; Lemes, Elisa Souza; Brunes, André Pich; Dias, Igor Leitzke; Meneghello, Géri EduardoThe production and physiological seed quality are directly associated with a good availability of nutrients in the crop. Seed production in areas with zinc deficiency, can generate seeds with low content and concentration of this micronutrient, the logo may be less vigorous seedlings, which may reflect in low yield. In this context, this work aims to evaluate the influence of seed coating with zinc in oat seed ...
