“…Stimulate ® is able to trigger root development, thus increasing the absorption of water and nutrients by roots, and possibly promoting the hormonal balance of the plant (SANTOS; VIEIRA, 2005). According to Dantas et al (2012), the use of growth regulators during the early stages of plant development promotes root growth, enables rapid recovery after water stress, increases resistance to insects, pests, diseases and nematodes, and promotes the quick and uniform establishment of plants, which in turn improves nutrient absorption and yield.…”

The aim of this study was to assess the germination and vigor of Bixa orellana seeds that were pre-soaked in different concentrations of Stimulate ® plant biostimulant. For the standard germination test, Bixa orellana seeds from the Embrapa 37 Cultivar were pre-soaked (for periods of four and eight hours) in the following concentrations of Stimulate ® aqueous solution: 3.0; 6.0; 9.0; and 12.0 mL L -1 . Seeds that were pre-soaked in distilled water were used as control. The following parameters were tested: germination; first germination count; abnormal seedlings; length; and seedling dry mass. The experimental design was completely randomized and a 2 x 5 + 1 factorial design was used (with two pre-soaking periods, five Stimulate ® concentrations, and one additional control without pre-soaking). Four replicates of 50 seeds were performed for each treatment. Water immersion treatments for four and eight hours were efficient for breaking dormancy in Bixa orellana seeds, since they promoted better germination in relation to the intact seeds that were not pre-soaked. The presoaking of Bixa orellana seeds for eight hours in a 12.0 mL L -1 Stimulate ® concentration presented the best results in terms of germinative performance and seedling growth, with greater accumulation of dry mass. Therefore, this practice is recommended for the production of seedlings of this species.

“…Segundo Dantas et al (2012), a aplicação de reguladores de crescimento durante os estádios iniciais de desenvolvimento da planta promove o crescimento a raiz, permite a rápida recuperação após o estres se hídrico, aumenta a resistência a insetos, pragas, doenças e nematoides e promove o estabelecimento de plantas de forma rápida e uniforme que melhora a absorção de nutrientes e o rendimento.…”

RESUMO: Para as gramíneas o nitrogênio é o nutriente requerido em maior quantidade, tem função estrutural e desempenha ainda importante papel na constituição de inúmeras substâncias e compostos, como aminoácidos e proteínas e na participação de processos metabólicos como fotossíntese, respiração e na absorção iônica de nutrientes, necessitando, portanto, de um adequado manejo no sistema produtivo. Deste modo, o objetivo deste trabalho foi avaliar o efeito do uso da ureia revestida com Cu e B e de produtos foliares comerciais na cultura do milho safrinha. O delineamento experimental foi em blocos casualizados, constituído de 10 tratamentos e quatro repetições, utilizando dois fertilizantes à base de ureia: ureia comum, fertilizante convencional perolado (45% de N) e ureia revestida com boro e cobre (44,6% de N, 0,087% de cobre e 0,231% de boro) e mais 5 produtos comerciais recomendados para aplicações foliares: Potamol Plus®, Stimulate®, Starter Manganês®, Tecmilho® e Phytogard®. A utilização da ureia revestida com (B) + (Cu) propiciou plantas maiores e mais vigorosas e o uso associado da ureia revestida juntamente com o Potamol plus® e o Tecmilho® aumentou a produtividade de grãos de milho.Palavras-chave: Zea mays L..

APPLICATION OF COATED UREA AND FOLIAR PRODUCTS ON SECOND CORN CROP SUMMARY:For grasses nitrogen is the nutrient required in greater quantity and therefore, It has structural function and plays also an important role in the formation of numerous substances and compounds such as amino acids and proteins, and the involvement of metabolic processes such as photosynthesis, respiration and ion absorption of nutrients, requiring therefore an adequate management in the production system. The objective of this study was to evaluate the effect of using the coated urea with Cu and B and commercial foliar products on second corn crop. The experiment consisted of randomized blocks with 10 treatments and four replications, using two fertilizer urea-based: common urea fertilizer conventional pearlescent with 45% of N and urea coated with boron + copper ( 44.6% of N, 0.087% copper and 0.231% boron) and 5 more recommended commercial products for foliar applications: Potamol plus®, Stimulate®, Starter manganês®, Tecmilho® and Phytogard®. The use of coated urea (B) + (Cu) provided higher and more vigorous plants and combined use of urea coated with the Potamol plus® and Tecmilho® increased productivity of grains.Keywords: Zea mays L..Top dressing.

“…Por exemplo, a mesma concentração de um determinado hormônio pode causar o crescimento do caule e ao mesmo tempo inibir o crescimento das raízes. Em plantas de tamarindo (Tamarindus indica L.) Dantas et al (2012) relatam que a pulverização foliar do bioestimulante Stimulate ® nas concentrações 0,8; 1,6; 2,4 e 3,2 mL L -1 promoveram aumento na altura das plantas e da parte aérea e massa seca da raiz. Já aplicações isoladas de giberelina não teve nenhum efeito sobre o diâmetro de caule, comprimento de raiz e massa seca de caule e raiz.…”
