Growth and solar energy conversion efficiency were studied in soybean cv. Parand cultivated on two substrata (soil and soil + sand) and treated with four metribuzin rates (0.0, 0.3, 0.6 and 0.9 kg ai.haTM1) under greenhouse conditions at Vigosa, MG, Brazil. The structural differences between the two substrata. soil (6% of organic matter and 40% of clay) and soil + sand (4% of organic matter and 29% of clay) affected the growth of the soybean.
