Resumo: | In Brazil soybean is the agricultural crop that occupies the largest a rea sown, has great importance in the production of vegetable oil, feed for animal feed and use in the chemical and food industry. In order for a good development of soybeans and high yields to occur, micronutrient fertilization should be emphasized and essential for plant growth and play an important role in balanced nutrition of crops. In this context, the objective of this study was to propose responses to soybean yield as atypical doses of micronutrient, zinc (Zn), boron (B), manganese (Mn) and copper (Cu) applied on the pre-planting soil surface. The studies were developed in Sinop-MT, from October to February in the 2017/18 harvest, with latitude 12 ° 03'50.3 "S, longitude 55 ° 33'13.1" W, and altitude of 383 meters with flat topography. the experiment was conducted under a randomized block design (DBC), containing 5 experiments with 5 treatments and 5 replicates, the plots were 5 x 7 m in size. The doses for boron and copper, namely: 0, 3, 6, 9 and 12 kg ha-1; manganese and zinc, namely: 0, 4, 8, 12 and 24 kg ha-1 and in addition a mix with all these micronutrients, separated for each dose interval. The cultivar NS 7901 RR was used. The Zn, Mn, B and Cu sources were Zinc Sulfate (20%), Manganese Sulphate (26%), Borogran (8%) and Sulfate of Copper (25%) . It was evaluated after harvest, productivity, weight of thousand grains, number of grains per plant, number of grains per pod, number of pods per plant and stand. Statistical analyzes did not present differences between treatments for Zn, Mn and Cu doses , resulting in a significant difference for boron and complete. For Zn these results probably occurred because the zinc content was higher than the critical level in the 0 -20 cm depth (SOUSA and LOBATO, 1998). In this case, the probability of response to zinc application is low (Anderson et al., 2003; ARAÚJO, NASCIMENTO et al., 2003). However, the Mn doses were demonstrated by Pinto (2012) that the efficiency of the application of Mn in the soil in general is low, and requires the application of doses cons idered high in relation to the micronutrients. However, in the present work (1.5, 3.0, 6.0, 12.0, and 48.0 kg ha-1), there were also increases in the levels of the micronutrients in the soils, but the concentration and amount of Mn accumulated by the soybean plants were little influenced. Probably due to the concentration of Copper being adequate in the soil, may have influenced the absence of a significant difference between the treatments, these data corroborate with works carried out by Borkert, (2002) who also showed no response to copper fertilization in four years of cultivation of soybeans, in two soils, one of clayey texture and one of medium texture. Therefore for B and complete it was observed that when done to the fertilization boratada in increasing doses there was a decrease in the stand of plants, that is, germination failure by Boro toxicity, being one of the factors that in the end affected the components of production and productivity of soybeans. |

Para que ocorra um bom desenvolvimento da soja e altas produtividades, destacasse a adubação de micronutrientes, sendo essencial para o crescimento das plantas e desempenham um papel importante na nutrição equilibrada das culturas. Neste contexto, o presente estudo teve o objetivo de propor a obtenção de respostas na produtividade da soja na medida em que são testadas doses atípicas de micronutriente, zinco (Zn), boro (B), manganês (Mn) e cobre (Cu) aplicados na superfície do solo em pré-plantio. Os estudos foram desenvolvidos em Sinop-MT, no período de outubro a fevereiro na safra 2017/18, com latitude 12°03'50.3"S, longitude 55°33'13.1" O, e altitude de 383 metros com topografia plana. o experimento foi conduzido sob delineamento de blocos casualizados (DBC), contendo 5 experimentos com 5 tratamentos e 5 repetições, as parcelas apresentavam dimensão de 5 x 7 m. As doses para boro e cobre, a saber: 0, 3, 6, 9 e 12 kg ha-1; manganês e zinco, a saber: 0, 4, 8, 12 e 24 kg ha-1 e além destes, um mix (Completo) com todos esses micronutrientes, separados para cada intervalo das doses. Utilizou-se a cultivar NS 7901 RR. A distribuição dos fertilizantes feita a lanço de forma manual e uniforme, utilizou-se como fonte de Zn, Mn, B e Cu respectivamente Sulfato de Zinco (20%), Sulfato de Manganês (26%), Borogran (8%) e Sulfato de Cobre (25%). Avaliouse após a colheita, produtividade, peso de mil grãos, número de grãos por planta, número de grão por vagem, número de vagens por plantas e estande. As analises estatísticas não apresentaram diferença entre os tratamentos para doses de Zn, Mn e Cu, resultando em diferença significativa para boro e completo.Para Zn esses resultados provavelmente ocorreram devido ao teor de zinco ser superior ao nível critico na profundidade de 0-20 cm (SOUSA; LOBATO, 1998). Neste caso a probabilidade de resposta à aplicação de zinco é baixa (ANDRÉ et al., 2003; ARAÚJO; NASCIMENTO, 2005; ROSA et al., 2003). Já as doses de Mn foram demonstradas por Pinto, (2012) que a eficiência da aplicação de Mn no solo de maneira geral é baixa, e necessita a aplicação de doses consideradas elevadas em relação aos micronutrientes. Moreira et al., (2006) também trabalhando com doses semelhantes ao presente trabalho (1,5; 3,0; 6,0; 12,0; e 48,0 kg ha-1) observaram de modo geral, aumentos nos teores do micronutriente nos solos, mas a concentração e a quantidade de Mn acumuladas pelas plantas de soja foram pouco influenciadas. Provavelmente devido à concentração de Cobre estar adequada no solo, pode ter influenciado a ausência de diferença significativa entre os tratamentos, esses dados corroboram com trabalhos realizados por Borkert, (2002) que também demonstrou não obter resposta à adubação com cobre, em quatro anos de cultivo de soja, em dois solos, um de textura argilosa e outro de textura média. Portanto para B e completo observou que, quando feito à adubação boratada em doses crescentes houve um decréscimo no estande de plantas, ou seja, falha de germinação por toxidez de Boro, constituindo um dos fatores que no final tenham afetado os componentes de produção e produtividade da soja.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Agrárias e Ambientais (ICAA) – SinopUFMT CUS - SinopAgronomia - CUSLange, Andersonhttp://lattes.cnpq.br/3211089100338805Lange, Andersonhttp://lattes.cnpq.br/3211089100338805Coletti, Admar Juniorhttp://lattes.cnpq.br/5553886744068023Aguiar, Beatriz Limahttp://lattes.cnpq.br/2527633553606526Silva, Claudison José da2019-04-17T13:56:19Z2018-03-072019-04-17T13:56:19Z2018-03-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetSILVA, Claudison José da.
