“…These results are in agreement with Almeida & Soratto (2014), who stated that the application of biostimulants did not affect root growth and, consequently, there was no effect on soil exploration and P uptake by the bean crop. For Ca and Mg, liming was possibly enough to meet crop needs.…”

“…K is directly related to biochemical activities, enzyme activation, opening and closing of stomata, photosynthesis and fruit formation (Barragán et al, 2012). This result differs from those found by Silva et al (2009) and Almeida & Soratto (2014), in the bean crop.…”

“…Regarding the application effects of the plant bioregulators on the nutritional content, Almeida & Soratto (2014) found, in the bean crop, that treatments with biostimulants showed higher levels of K, Mg, Ca, S, Mn, Fe and B, although Lana et al (2009) found no increase in macro and micronutrients in bean plants treated with biostimulants.…”

Biostimulants are used in cotton (Gossypium hirsutum L.) to balance vegetative and reproductive growth as well as to increase cotton seed yield and fiber quality. Therefore, in order to study the efficiency of seed treatment with biostimulants, nutrition, production and technological quality for the cotton fiber, a field experiment was installed. The study was conducted at the Alvorada farm research field, in Luis Eduardo Magalhães municipality - BA. The experiment was arranged in a completely randomized block design with four replicates and five treatments (control group, untreated group, Booster®, Stimulate®, Improver® and Biozyme®). Leaf contents of nutrients, yield and technological quality of the fiber were evaluated. The results showed that application of biostimulants in the seeds increased the N, K, S and Fe contents in the cotton leaf, but there was no influence on the crop yield. However, these products caused changes in the fiber characteristics, related to length uniformity, micronaire, length and strength of the fiber.

“…Tabela 4 -Equações referentes à NVP de feijoeiro em função das doses de bioestimulante e indutor de resistência, coeficiente de determinação, significância estatística, dose de máxima eficiência (DME), incremento e eficiência O incremento nos valores obtidos para NVP pode estar relacionado com a auxina presente no bioestimulante que participa de processos metabólicos do crescimento, principalmente pelo alongamento celular, além de retardar a abscisão de flores recém-fecundadas e vagens em formação, sendo assim, é uma substância que desempenha papel importante na fisiologia da planta. A cinetina, presente no bioestimulante, também possui papel decisivo na fixação biológica de nitrogênio (SUZAKI et al, 2013), que, além de contribuir para a nutrição da planta, também promove o carreamento de nitrato, sulfato e fosfato, garantindo adequada nutrição para a planta, podendo assim expressar produtividade (ALMEIDA; SORATTO, 2014).…”

Em busca do aumento da produtividade do feijoeiro e de várias outras culturas de interesse econômico, foram realizadas inúmeras pesquisas utilizando reguladores de crescimento, hormônios e nutrientes, principalmente em aplicações foliares com a finalidade de acelerar o desenvolvimento da planta, melhorar suas características agronômicas, garantir maior sanidade e desempenho em campo. A aplicação de reguladores vegetais bioestimulantes com a finalidade de aumentar a produtividade das culturas é prática ainda pouco usual na agricultura. Assim, objetivou-se com este estudo avaliar o efeito da aplicação de bioestimulante vegetal associado a um indutor de resistência nos componentes de produção do feijoeiro. Foram utilizadas cinco doses de um bioestimulante (ácido indolbutírico, cinetina e ácido giberélico), sendo 0; 0,5; 1,0; 1,5 e 2,0 L ha-1, combinado com quatro doses de um indutor de resistência (0,5; 1,0; 2,0 e 3,0 L ha-1) no feijão comum, cv. IAC Formoso, em sistema de plantio direto. O experimento foi conduzido em Selvíria-MS, no ano agrícola 2013/14. O delineamento experimental foi em blocos casualizados, em esquema fatorial (5x4), com quatro repetições. Foram avaliados os componentes da produção e a produtividade de sementes da cultura. O indutor de resistência proporcionou maiores valores de matéria verde (52,08 g planta-1) e seca (17,29 g planta-1) de feijoeiro, respectivamente, nas doses de 2,04 L ha-1 e 2,15 L ha-1. A maior produtividade (3756 kg ha-1) foi obtida na dose de 0,78 L ha-1 do bioestimulante. O uso do bioestimulante vegetal pode ser uma alternativa viável para o aumento de produtividade do feijoeiro.

Biostimulating microorganisms have protector effect against pathogenic agents, affect the stand formation, promote plant growth, and increase yield of agricultural crops. Thus, the objective of this work was to evaluate the seed germination and seedling emergence of different common bean cultivars as a function of treatments with Bacillus subtilis BV02 and Trichoderma asperellum BV10. Germination tests in paper rolls and sand were conducted in a completely randomized design, with a 2×4 factorial arrangement consisted of two cultivars, namely Campos Gerais (CG) and Estilo (ES), and four microorganism treatments, namely B. subtilis BV02 (BS), T. asperellum BV10 (TA), B. subtilis BV02 + T. asperellum BV10 (BS+TA), and Control. The variables analyzed were: germination speed index (GSI), emergence speed index (ESI), germination percentage, emergence percentage, root length, seedling height, and root and shoot fresh and dry weights. The CG cultivar had higher GSI, ESI, root length, seedling height, shoot fresh weight, root fresh weight, and shoot dry weight than the ES cultivar in the paper roll and sand tests. The common bean seed inoculation with BS+TA increased seedling height, shoot fresh weight, shoot dry weight, and root length in the ES cultivar. The CG cultivar had higher GSI, ESI, root length, root fresh weight, and root and shoot dry weights than the ES cultivar. The treatment of seeds with BS+TA is recommended to improve the performance of common bean seedlings of the ES cultivar.
