Research presented below was carried out in the summer of 2015 in the experimental field San Antonio de los Bravos of the UAAAN in Torreon Coahuila Mexico. Under the system of pumping irrigation to established two areas of 44 m² each with the purpose of assessing the variety of bean pinto-saltillo in the following modalities: conditions of agriculture conventional as a witness and as experiment farming the plot was established in terms of conservation agriculture in the form of tillage with multiple plow. Is intended to make a comparison of difference of groups by means of the test t student with a α = 0.05; the hypothesis to defend is that conservation and an appropriate method of tillage agriculture generates higher yields, lower costs of production and as a result are accomplished best utilities for producers. The truth given to credit was accepted, because in the statistical analysis applied if found significant differences between the evaluated groups. With regard to the economic analysis was a projection between conventional tillage and tillage with multiple plow method, and found a difference of marginal utility of $3168.00 pesos per hectare in the comparison of the two methods; This in favor of conservation tillage with multiple plow
