Boron 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 ...
O presente trabalho teve por objetivo analisar a metodologia do teste de envelhecimento acelerado, bem como verificar a possibilidade do uso de Cloreto de Sódio (NaCl) como opção para controle da absorção de água pelas sementes durante a realização do teste. Foram utilizados cinco lotes de sementes, submetidos aos testes de germinação (G), emergência de plântulas (EP), índice de velocidade de emergência (IVE) e...

Use 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...
The study aimed to evaluate the influence of physiological seed quality on the spatial distribution of plants in the field, as well as the effect on variability among soybean plants. Six lots of soybean cultivar CD 202, with three vigor levels (high, medium and low) and two lots on each level were used. Lots of high physiological quality showed germination of 96% and lots considered of medium vigor showed 82% o...
The 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 ...
O trabalho teve por objetivo avaliar o efeito da adubação silicatada no acúmulo de silício e compostos fenólicos na parte aérea de plantas de trigo. O delineamento experimental foi inteiramente casualizado onde os tratamentos consistiram na utilização de diferentes doses de duas fontes de silício, em esquema fatorial 2 X 6 (Fator A: caulim e cinza de casca de arroz, Fator B: níveis de zero, 500, 1000, 1500, 200...
Micronutrients, such as zinc, are important for the metabolic activities that can benefit germination and seed vigor because many soils are deficient in this micronutrient. The objective of this study was to evaluate the influence of coating oat seeds with zinc on the physiological quality and yield of the seeds produced. The experimental design was completely randomized, with a 2 x 5 factorial arrangement of t...
O presente trabalho teve por objetivo determinar a metodologia do teste de envelhecimento acelerado para avaliação do potencial fisiológico de sementes de brócolis, bem como, verificar a possibilidade do uso de solução contendo NaCl como alternativa para controle da absorção de água pelas sementes durante a realização do teste, sem reduzir sua sensibilidade. Foram utilizados quatro lotes de sementes, submetidos...
