The present work was carried out in the UBPC Antonio Maceo Grajales (El Palmar), located in the Agricultural and Livestock Company "Paquito Rosales" in the province of Granma, Cuba. It was carried out with the objective of evaluating the effect of two minimized farming systems on a Fluvisol soil for the cultivation of beans, taking into account the behavior of humidity of the soil and the cultivation´s agricultural yields. The treatments under study were: T1 for minimized farming and T2 for reduced farming. T1 consisted of the plowing of the soil with multi-plowing device followed by one pass of disc harrow. T2 is considered a variant of the previous treatment followed by two perpendicular passes of disc harrow. As results T1 obtained the best behavior in maintaining a better conservation of the soil in the profile of 0-30 cm depth. The highest humidity content (29,21 %) was obtained at the fourth observation date, which facilitated better root penetration and cultivation development, reaching an agricultural yield of 0,97 t ha-1, 28 % higher than the one obtained by T2.
