Abstract

The incorporation of new technologies has provided large yield increases, the most recent being related to the seed industry. Especially in large farms, in order to speed up the planting process and reduce the number of employees and the time of exposure of the seeds to adverse conditions, these are being purchased already treated with insecticides and fungicides or without industrial treatment. The present work had as objective to evaluate the foliar application of a commercial product containing molybdenum and cobalt in the soybean crop, aiming to increase the yield components and physiological quality of the seeds produced. The seeds were treated with Maxim fungicide and Avicta insecticide from the company Syngenta. Yield components (thousand seed weight, grain yield, number of pods per plant and number of seeds per pod) and physiological quality of seeds (first germination count, germination, accelerated aging, field emergence and tetrazolium) were analyzed.The experimental design was randomized blocks with four replications and six treatments with different doses.The results obtained for the variables thousand seed weight, number of pods per plant and grain yield were not influenced by the application of the different treatment doses. For the variable number of seeds per pod, the treatments had a significant effect, there was an increase up to the dose of 240 mL.ha-1 with the application of the product containing cobalt and molybdenum.The decrease in the number of seeds per pod from this dose may be due to the phytotoxic effect of cobalt. Excess cobalt can cause toxicity and symptoms are necrotic spots on cotyledons and leaves with chlorotic leaflets.For the variables regarding first germination count, germination and field emergence of the seeds produced, coming from plants that received the application of different doses of the product containing the micronutrients molybdenum and cobalt in the V5 stage of development of the soybean crop, there was a significant effect of application of the product.Regarding the accelerated aging test, no significant effect was observed in the different treatments.The molybdenum and cobalt doses have a positive effect on the physiological quality.
