Use efficiency of water and radiation in soybean under competition with Alepo sorgo.

The objective of this study was to evaluate the use efficiency of water and radiation (WUE and RUE) of two soybeans cultivars growing under different plant densities, row spacing and competition with glyphosate resistant Aleppo sorghum. In general, the presence of weeds reduced tot...

EFICIENCIA DE USO DE AGUA Y RADIACIÓN EN SOJA BAJO COMPETENCIA CON SORGO DE ALEPO PIETROBÓN, M. IMVINKELRIED, H. O. DELLAFERRERA, I. M. GARIONE, G. HAIDAR, L. The objective of this study was to evaluate the use efficiency of water and radiation (WUE and RUE) of two soybeans cultivars growing under different plant densities, row spacing and competition with glyphosate resistant Aleppo sorghum. In general, the presence of weeds reduced total dry matter, yield, WUE and RUE. The increase in density and the decrease in row spacing improved WUE and RUE and increased total dry matter and yield. Soybean cultivar with the highest maturity group accumulated more dry matter than that with the lowest maturity group. However, both cultivars showed similar yields and RUE. El objetivo de este trabajo fue evaluar la eficiencia en el uso de agua y radiación (EUA y EUR) de dos variedades de soja creciendo bajo diferentes densidades de plantas, espaciamiento entre surcos y competencia con sorgo de Alepo resistente a glifosato. De forma general, la presencia de malezas redujo la materia seca total, el rendimiento, la EUA y la EUR. El aumento en la densidad y la disminución del espaciamiento entre surcos mejoró la EUA y la EUR e incrementó la materia seca total y el rendimiento. La variedad de mayor grupo de madurez acumuló más materia seca que el de menor grupo de madurez. Sin embargo, ambas variedades presentaron similares rendimientos y EUR.
