Abstract

The objective of this work was to evaluate the performance of soybean seedlings in different seed treatments. The experiment was conducted in the municipality of Mineiros, GO. The soil was classified as Quartzarenic Entisol. The experimental design was randomized blocks in factorial 5x4, corresponding to seed treatments (Water, Cruiser, Fipronil Alta, Fortenza and Standak Top) in four soybean cultivars (Bonus, Ultra, Extra and BKS7830), in four replications. Before planting, pre-planting desiccation was performed. The fertilization used was 450 kg ha-1 of fertilizer 05-25-15 applied in the furrow and in a single dose next to the sowing. During the conduction of the experiment the control of pests, diseases and weeds were carried out as necessary, respecting the best practices and integrated management. The data obtained were subjected to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Uni and multivariate tools were applied. The analysis were performed at the interface Rbio and R. The interaction of soybean cultivars and types of seed treatment showed variations in all analysis evaluated in soybean seedlings. The best performances were verified among the cultivars BKS7830 that expressed the largest shoot fresh matter when submitted to Cruiser seed treatment, while the highest root length was expressed in the cultivar Ultra in the Fortenza seed treatment.

Highlights

Soybean seedling performance in diferente...Soybean (Glycine max (L.) Merrill) is a legume originating in China and one of the main agricultural commodities in Brazil and in the world (Bernardeli et al, 2020; Ferreira et al, 2022)
Its high importance is due to the fact that it has high levels of oil (20%) and, mainly, protein (40%) (Lopes, Vello, Pandini, Rocha, & Tsutsumi, 2002), as well as nutrients such as nitrogen (51.9 g Kg-1), phosphorus (3.7 g kg-1) and potassium (17 g kg-1) (Loro et al, 2021), which justifies its economic importance, as it is used for the manufacture of animal feed (Ministério da Agricultura, Pecuária e Abastecimento [MAPA], 2018)
Data were taken according to methodology of the Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) (2009)

Summary

Introduction

Soybean seedling performance in diferente...Soybean (Glycine max (L.) Merrill) is a legume originating in China and one of the main agricultural commodities in Brazil and in the world (Bernardeli et al, 2020; Ferreira et al, 2022). The United States is the world's leading soybean producer, accounting for 35.51% of world production and 3299 kg ha-1 yield (Empresa Brasileira de Pesquisa Agropecuária [EMBRAPA], 2018). Soybean in Brazil has established itself as one of the prominent products in agriculture, being one of the fastest growing crops in the last three decades (MAPA, 2018). The country is the second largest soybean producer in the world, being responsible for producing on mean 34.76% of world crop production, with a mean yield of approximately 3333 kg ha-1. Among the Brazilian states, the state of Mato Grosso is the largest soybean producer, with an area of 9,519 thousand hectares, and the state of Paraná has the highest yield in the country, with 3503 kg ha-1 (EMBRAPA, 2018)
