Efecto de algunas enzimas sobre la absorción foliar del nitrógeno

Two different crops, cacao and corn were submitted to urea sprays with 2 to 4 percent of enzymes added in a single application. The enzymes used were pectinase, pepsin, trypsin and pronase. Results indicate that enzimes increase the foliar absorption of urea apparently by affecting the leaves surfac...

Summary:Two different crops, cacao and corn were submitted to urea sprays with 2 to 4 percent of enzymes added in a single application. The enzymes used were pectinase, pepsin, trypsin and pronase. Results indicate that enzimes increase the foliar absorption of urea apparently by affecting the leaves surface. Pectinase had the greatest effect on the absorption of urea by leaves.
