The objective of this work was to determine the optimum soybean population level and seeding rates for high yields in three Brazilian soybean cultivars. These experiments was carried out in the following locations: Experimental Farm Getúlio Vargas, in Uberaba (743 m altitude), Experimental Station of Cooperativa Agropecuária Mista do Programa de Assentamento Dirigido do Alto Paranaíba Ltda, in Rio Paranaíba (1100 m altitude), and Capão da Onça Farm, in Conceição das Alagoas (500 m altitude). The Brazilian cultivars BRSMG Renascença, BRSMG 68 and BRSMG Garantia were evaluated in 0.45, 0.30, 0.25, 0.20, and 0.15 m row spacing combining seeding rates to obtain plant population ranging from 100.000 to 400.000 plants/ha. Plant population near to 240,000 plants/ha produced higher yields for BRSMG 68 and BRSMG Garantia. At the common row spacing used in Brazil (0.45 m), plant populations higher than 240,000 did not increase grain yield. The early-maturing soybean cultivar BRSMG Renascença showed more yield in higher plant population than another cultivars. Narrow row spacing was more profitable than wider ones.1 aARANTES, N.
