In a Typic Haplustalfs (USDA) soil of the municipality of Palmira – Valle (Colombia) the rotation system velvet bean Mucuna pruriens Var. Utilis – maize Zea mays L. was established in design of complete blocks at random with seven treatments and three repetitions. The treatments in the rotation were: T1 (Without M. pruriens and fertilizing), T2 (green manure of M. pruriens without fertilizing), T3 (mulching of M. pruriens without fertilizing) T4 (green manure of M. pruriens more compostado organic manure), T5 (green manure of M. pruriens more fertilizer of chemical synthesis), T6 (green manure of M. pruriens plus complemented compostado organic manure with fertilizer of chemical synthesis), T7 (mulching of M. pruriens plus complemented compostado organic manure with fertilizer of chemical synthesis). The energy balance was characterized and contributes nutritional using software Energy 3.01., from the entrances energetics in each treatment. The greater efficiency was obtained energetics in the T2 with 114.1 Mj.Mj-1 that was significantly greater (p<0.05) to the other treatments. The T5 where fertilization of chemical synthesis was used obtained value of 19.1 Mj.Mj-1, reflecting high entrances energetics and low productivity. The majors contribute nutritional were obtained in T3, T4, T6 and T7. Nevertheless, the treatments T3 and T4 stand out respectively where it was used mulching and green manure of M. pruriens more compost; since they are treatments where more efficient use becomes of the power resources by the use of consumptions readily accessible for the producer, being able to generate benefits like feeding for almost 50 persons.ha-1.year-1. These results suggest this valuable alternative association as for use in familiar agriculture farmer.
