Effect of the organic transition system on soybean growth and nodulation

Abstract

The aim of this study was verify the influence of the cultivation system on nodulation and
growth of two cultivars, conventional and genetically modified (RR), soybeans. The experiment
was carried out in the agricultural year 2016/17 in the Department of Plant Science of UFSM.
Genetically modified cultivars BMX Potência RR, and BRS 257, conventional, were sowed in
experimental units of six rows with seven meters in length, spaced at 0.45 m. In two separate
areas both as cultivars were managed in conventional system and in organic transition. The
evaluations were taken at the R4 stage of culture. There was no influence of management on
the diameter of the main stem, number and diameter of nodules. In the conventional management
to transgenic cultivar presented superior height to non-genetically modified cultivar.
