ABSTRACT: The
soybean crop has great economical importance in Brazil and in the world. In
order to make the crop production profitable, several factors must be considered.
The objective of this study was to evaluate the impact of spacing between
soybean crop rows (Glycine max). The
experiment was installed in the Mutuca farm
(Arapoti—PR, southern Brazil), in the crop seasons of
2012/2013 (four seeding seasons) and 2013/2014 (two seeding seasons), in a
completely randomized blocks design. We used four treatments and six
replicates. The treatments were the spacing between rows as follow: 0.25, 0.50,
0.75 and 1.00 m. The variables evaluated were: initial and final plant
population, plant height, number of internodes, viable internodes, pods per
plant, grains per pod, mass of thousand grains and crop productivity. We
concluded that the reduction of the spacing between rows significantly
increased, in most part of the crop seasons, the number of pods per plants and
the crop productivity.
