Geotemperatura, flujo neto de calor del suelo y variables morfológicas del cultivo de soya (Glycine max L.) bajo condiciones de mulch plástico

Most crops are affected by various factors, plastic mulch emerges as an alternative, causing a positive impact on the temperature in root zone, microbial life and physical properties of soil associated with improvement crop yield. The objective research was to evaluate yield soybean (Glycine max L.) under conditions. Geotemperature parameters, net heat flow from morphological variables were analyzed. completely randomized design used, study factor different colors: black (T1), red (T2), blue (T3), green (T4) control (T0, bare ground). results showed that influences up 6 °C respect flux, colors relevant, well variables, being treatments T3 T4, ones had best compared soil, improving 2 t ha-1. Blue is viable option improve productivity economic performance.
