“…Essa característica, normalmente, não é influenciada, por ser uma característica genética de alta herdabilidade. Esses valores são próximos aos observados por Borges et al (2014) trabalhando com a mesma cultivar de soja, na mesma região da condução deste trabalho.…”

Resumo: A presença de animais nos sistemas de integração lavoura-pecuária (ILP) é causa de preocupação para produtores no que se refere à compactação do solo. Objetivou-se, com este trabalho, avaliar as características agronômicas da cultura de soja cultivada sob plantio direto em área de ILP preparada ou não com descompactador "matabroto". O experimento foi conduzido na safra agrícola 2013/2014, na área experimental pertencente à Fazenda Santa Brígida, município de Ipameri, Goiás. O delineamento experimental foi de blocos inteiramente casualizados com dois tratamentos e dez repetições. Os tratamentos estudados foram constituídos de dois métodos de preparo do solo (T1=sem matabroto e T2=com matabroto Ikeda 30 dias antes da semeadura, com profundidade de 35 cm). Foram avaliadas as seguintes características: estande final de plantas, altura de inserção da primeira vagem, altura das plantas, comprimento da raiz principal, número de vagens por planta, número de hastes por planta e produtividade. Os resultados obtidos foram submetidos à análise de variância e ao teste t de Student, a 5% de probabilidade. Os diferentes tipos de preparo de solo não surtiram efeito para as características de estande final, altura de inserção da primeira vagem, altura de planta, número de hastes por planta e número de vagens por planta. Entretanto, a utilização do matabroto promoveu incremento no comprimento da raiz principal, o que provavelmente resultou em melhor aproveitamento de água e nutrientes pela planta, proporcionando maior produtividade de grãos, quando comparada à não utilização do matabroto em área sob plantio direto.

The objective of this work was to evaluate the agronomic characteristics of soybeans cultivated under a no-tillage system in the crop-livestock integration area, which was prepared with and without the use of a "matabroto" decompressor. The experiment was conducted in the agricultural crop of 2013-2014, in the experimental area belonging to Fazenda Santa Brígida, in the municipality of Ipameri, Goiás, Brazil. The experimental design included completely randomized blocks with two treatments and ten replicates. The treatments were composed of two methods of soil preparation (T1=without matabroto; and T2=with matabroto Ikeda 30 days before sowing, with a depth of 35 cm). The following characteristics were evaluated: final plant stand, first pod insertion height, plant height, main root length, number of pods per plant, number of stems per plant, and productivity. The results were submitted to a variance analysis and Student's t-test at a probability of 5%. The different types of soil preparation had no effect on the characteristics of the final stand, first pod insertion height, plant height, number of stems per plant, and number of pods per plant. However, the use of matabroto promoted an increase in the length of the mai...

“…The application of biostimulants containing cytokinin or the isolated use of the growth regulator, via foliar applications, has shown a strong tendency to increase the yield of soybean crop (Soares, Dourado Neto, Fagan, Teixeira, & Pereira, 2017). Borges, Torres Junior, Neves, Cruvinel, Santos, and Matos (2014), when applying N6-benzyladenine (6-BA) at the end of soybean flowering, found a reduction of pod abortion, and an increase of stem diameter, the yield of components and the crop. Metivier and Paulilo (1980), when evaluating the time of soaking of bean seeds in 6-BA, observed an increase in embryo axis dry mass, maltose and tyrosine release, and amino acid production.…”

In field conditions, the more usual application of cytokinins is based mainly on seed treatment and foliar spraying. Nowadays, seed priming with plant growth regulators is a successful agricultural practice due to its easy application in annual crops, resulting in a higher vigor and production. In order to evaluate the effect of the treatment of common bean seeds with N6-benzyladenine (6-BA), in the morphophysiology and crop yield, an experiment was carried out in a greenhouse, in a completely randomized design with four replicates and five doses of 6-BA (0, 0.0375, 0.075, 0.1125 and 0.15 g kg-1 of seed). The growth regulator was applied to the seeds in order to cover their entire surface. At 30 days after emergence, the physiological parameters were increased as a function of the doses of 6-BA. On the other hand, at 30 and 45 days after emergence of the crop, there was a drastic reduction in nodulation with increased 6-BA doses, which resulted in the lower accumulation of leaf nitrogen, pod number, and common bean yield. The ranging doses till 0.15 g kg-1 of seed of the cytokinin 6-BA are not recommended in seed priming of common beans. However, the effective recommendation of cytokinin as a seed priming is still not determined, and studies about products and doses must be improved before recommendation.
