The present research project was carried out in the fields belonging to the Universidad Nacional Agraria La Molina (UNALM). The technical staff of this university participated for the development of this project. The primary purpose was to compare the costs incurred by Conventional Agriculture against the Conservation Agriculture costs. Two seed-fertilizer-grain machines were built and tested, one of which was conditioned for direct sowing, adding a front disc for the development of the field trials. On the field tests of seed-fertilizer machines, the main parts, the costs of conventional planting versus sowing in conservation agriculture, their yields and the corrections necessary for a more efficient use were considered. It is from the determination of costs with estimated average value that we could define a criterion or reasoning to transform the decision problem under uncertainty into a problem of low decision risk. After the corrections of the seed dispenser, the inclusion of scrapers in the front and the change of material of the seed conductors, the corn was sown, resulting in good seeding. Sowing resulted in an increase in crop yields due to savings in working hours and machine hours, which affects planting costs about traditional planting. The results obtained were as follows: The American sowing machine was the one that yielded the greatest productions, both in Conventional Agriculture and in Conservation Agriculture. Under the first system, a gross value of 53.15 Tn/ha was obtained, generating a net income of S/.98.20, while in Conservation Agriculture 43.82 Tn/ha was obtained, generating a net income of S/.395.31 in the experimental field. It is necessary to mention that the highest rate of profitability was achieved under the system of Conservation Agriculture with 11.29%.
