Agronomic performance of soybean and its relation with the production environment

The objective of the work is to identify the agronomic performance of soybeans and correlate meteorological attributes with yield components. The study was carried out at the Escola Fazenda of the Regional University of the Northwest of the State of Rio Grande do Sul - UNIJUÍ, located in Augusto Pestana – RS. The experimental design used was randomized blocks, consisting of 10 genotypes and five replications. Descriptive analysis was performed using mean plus standard deviation for variables that presented a coefficient of variation greater than 35%; normality and homogeneity tests were also performed, as well as analysis of variance, Tukey mean comparison tests and linear correlations supported by the t-test. Soybean grain yield is closely linked to meteorological elements, which play a crucial role in the fluctuations and frustrations of soybean agricultural harvests in the municipalities of Rio Grande do Sul. The significant correlations between yield indicate that the water factor is what more affects production. The TMG7362IPRO cultivar had a higher yield with 73 bags per ha-1. -Iin this context, the soybean GMR also influenced yield in relation to climatic relations and had a better positioning.
