Abstract

Soybean has great importance in world economy. Their productivity is influenced by numerous factors like nutrition, pests, diseases, genetic factors, and weather and plant density to name a few, and the spatial distribution of plants per area a resource to increase productivity the aim of this study was to evaluate main items of productivity and soybean yield with different arrangements of plants with spacing (0.25 and 0.50 m), and population density of plants per unit area (351,000, 310,000, 270,000, 229,500 plants per hectare). The experiment was conducted in agricultural year 2013/2014, with cultivar CD 2610 IPRO® with determined type of growth and CD2611 IPRO® with indeterminate type of growth. The experiment design was conducted in a randomized block design with split-plot, containing three repetitions and for statistical analysis, we used Assistat program in sub-divided form. The two varieties tested showed significant results in 0.25 m space between plants with a density of 351,000 plants per hectare.

 

Key words: Arrangement, Glycine max, densities, growth.
