Resumo: | The production of high quality soy seeds is a challenge for the seed sector. Although little explored in the literature, it is known that plant mineral nutrition has a direct influence on seed production and quality, however, there is no consensus on the nutrients that relate to seed productivity and quality. Given the above, the objective of this study was to evaluate the effect of enriching soybean seeds with nickel and molybdenum on the physiological and health quality of the seeds produced. Two experiments were carried out, both with two soybean cultivars, where the seed treatment (nickel, cobalt and molybdenum) was combined with foliar applications of nickel and molybdenum. In both experiments, seed and protein productivity, chemical composition of seeds (oil, protein, nitrogen, nickel and molybdenum content), physiological quality (first count, germination, accelerated aging, electrical conductivity, emergence and speed index) were evaluated emergency) and sanitary quality (incidence of Aspergillus spp., C. kikuchii, Fusarium spp.). The treatment of soybean seeds with nickel, cobalt and molybdenum associated with the application of 10 g ha-1 of nickel increases the leaf contents of phosphorus, potassium, calcium, sulfur and boron. For the cultivar SYN 13610, seed treatment followed by foliar applications associated or not with 10 g ha-1 of nickel and 40 g ha-1 of molybdenum result in higher productivity. The application of molybdenum via seed treatment increases the content of this micronutrient in the seeds produced, an increase optimized with 40 g ha-1 of molybdenum via leaf. The foliar content of molybdenum increases with the treatment of seeds containing Ni, Co and Mo, but reduces with foliar application of nickel in TMG 7062. Isolated or associated applications of nickel in the V6 stage and molybdenum in R5.1 increase seed productivity of TMG 7062 and the total carbohydrate content in the seeds of M 6410. For the cultivar TMG 7062 the treatment of seeds with Ni, Co and Mo increases the retention of seeds in the 7.0 mm sieve. Both studied cultivars respond in a similar way to the enrichment of seeds with molybdenum, whose highest levels are obtained with the application of Ni, Co and Mo in the treatment of seeds followed by the foliar application of 40 g of Mo ha-1 at the R5.1 stage, associated or not with the application of 10 g of Ni ha-1 in the V6 stage. The enrichment of seeds with nickel improves the physiological quality, but increases the incidence of Aspergillus and Fusarium sp. On the other hand, enrichment of seeds with molybdenum has a high relationship with the protein and nitrogen content in the seeds, which do not contribute with quality of soybean seeds. |

Embora pouco explorado na literatura, sabe-se que a nutrição mineral de plantas exerce influência direta sobre a produção e qualidade de sementes, porém, não há um consenso sobre os nutrientes que se relacionam com produtividade e qualidade de sementes. Diante do exposto, objetivou-se com este trabalho, avaliar o efeito do enriquecimento de sementes de soja com níquel e molibdênio sobre a qualidade fisiológica e sanitária das sementes produzidas. Foram conduzidos dois experimentos, ambos com duas cultivares de soja, onde se realizou a associação do tratamento de sementes (níquel, cobalto e molibdênio) com aplicações foliares de níquel e molibdênio. Em ambos os experimentos foram avaliadas a produtividade de sementes e de proteína, composição química das sementes (teor de óleo, proteína, nitrogênio, níquel e molibdênio), qualidade fisiológica (primeira contagem, germinação, envelhecimento acelerado, condutividade elétrica, emergência e índice de velocidade de emergência) e qualidade sanitária (incidência de Aspergillus spp., C. kikuchii, Fusarium spp.). O tratamento de sementes de soja com níquel, cobalto e molibdênio associado à aplicação foliar de 10 g ha-1 de níquel, aumenta os teores foliares de fósforo, potássio, cálcio, enxofre e boro. Para a cultivar SYN 13610 o tratamento de sementes seguida de aplicações foliares associadas ou não com 10 g ha-1 de níquel e 40 g ha-1 de molibdênio resultam em maiores produtividades. A aplicação de molibdênio via tratamento de sementes eleva o teor deste micronutriente nas sementes produzidas, aumento este, otimizado com 40 g ha-1 de molibdênio via foliar. O teor foliar de molibdênio aumenta com o tratamento de sementes contendo Ni, Co e Mo, porém, reduz com aplicação foliar de níquel na cultivar TMG 7062. As aplicações isoladas ou associadas de níquel no estádio V6 e molibdênio em R5.1 aumentam a produtividade de sementes da TMG 7062 e o teor de carboidratos totais nas sementes de M 6410. Para a cultivar TMG 7062 o tratamento de sementes com Ni, Co e Mo aumenta a retenção de sementes na peneira 7,0 mm. Ambas cultivares estudadas respondem de maneira semelhante ao enriquecimento das sementes com molibdênio, cujos maiores teores são obtidos com a aplicação de Ni, Co e Mo no tratamento de sementes seguido da aplicação foliar de 40 g de Mo ha-1 no estádio R5.1, associada ou não à aplicação de 10 g de Ni ha-1 no estádio V6. O enriquecimento de sementes com níquel melhora a qualidade fisiológica. Por outra lado, o enriquecimento de sementes com molibdênio tem alta relação com o teor de proteína e nitrogênio nas sementes, os quais não contribuem com qualidade de sementes de soja.Universidade Federal de LavrasPrograma de Pós-graduação em Agronomia/FitotecniaUFLAbrasilDepartamento de AgriculturaOliveira, João AlmirCarvalho, Everson ReisSantos, Heloisa Oliveira dosVeiga, Patrícia de Oliveira AlvimVeiga, André DellyMauri, RobsonSilva, Hellismar Wakson da2021-05-11T16:25:06Z2021-05-11T16:25:06Z2021-05-112020-09-17info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfSILVA, H.
