Resumo: The objectives of the present study were to evaluate the effects of plant arrangement (row spacing and plant population) and fertilization levels on yield components and soybean yield. The experiment was performed at the Agronomic Experimental Station of Universidade Federal do Rio Grande do Sul (EEA/UFRGS), in Eldorado do Sul, Rio Grande do Sul, Brazil, in the 1996/97 growing season, in a Dark Red Podzolic sofi. The treatments were arranged in a split split-plot randomized complete-block design, white four replications. The cultivar tested was 1FT-Saray' (carly), in no-till. The treatments tested were three fertility levels (without fertilization, the recommended and twice the recommended fertilization), two populations (30 and 40 plants/m2) and two row spacing (20 and 40 cm). The average grain yield of 4871 kg/ha, was modified by the row spacing, where in 20 cm the grain yield was of 5420 kg/ha, 1098 kg/ha greater than in 40 cm rows (4322 kg/ha). In the row spacing of 20 em the number of pods per m2 was 1789, 16% greater than the 1544 produced in 40 cm, being this the most important component in the yield increase in 20 cm rows.

O experimento foi conduzido na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul (EEA/UFRGS), em Eldorado do Sul, RS, no ano agrícola de 1996/97, em solo Podzólico Vermelho Escuro (Paleudult). O delineamento experimental foi de blocos ao acaso, com parcelas sub-subdivididas e quatro repetições. Foi utilizada a cultivar de soja 'FT-Saray' (precoce), em semeadura direta, com os tratamentos constando de três níveis de fertilidade do solo (sem adubação, adubação recomendada c duas vezes a adubação recomendada), duas populações (30 e 40 plantas/m 2) e dois espaçamentos entre linhas (20 e 40 cm). O rendimento médio de grãos foi de 4871 kg/ha, tendo sido modificado pelo espaçamento entre linhas onde 20 cm apresentou rendimento de 5420 kg/ha, sendo 1098 kg/ha superior ao espaçamento de 40 cm (4322 kg/ha). No espaçamento de 20 cm o número de legumes/m2 foi 1789, 16% superior aos 1544 produzidos em 40 cm, sendo este o componente mais importante na determinação do maior rendimento obtido em linhas espaçadas de 20 cm. Departamento de Diagnóstico e Pesquisa Agropecuária.
