This research was carried out in Lamas, the general objective was to determine the effect of organic matter levels and horticultural cropping systems on soil quality. Specific objectives: To determine the effect of O.M. levels and horticultural cropping systems on crop growth and production and on water coefficients and soil chemical characteristics. The O.M. was cabbage biomass and the crops: Chinese onion, coriander, lettuce, radish and bean. A completely randomized block design was applied, with factorial arrangement, 2 levels of OM (40 and 80 t/ha) and 5 cropping systems consisting of Chinese onion, coriander, lettuce, radish, and an absolute control, with three replications. Factors studied, A: organic matter levels and B: cropping systems. The following were evaluated in crops: plant height, collar diameter, fresh matter weight, root mass weight, yield in kg/ha. In soils: physical-chemical analysis and water coefficients. Development and productivity results were subjected to analysis of variance and Duncan's test (P>0.05). Treatments with 80 t.ha-1 of cabbage biomass had better averages in the variables evaluated for Chinese onion, lettuce and radish in the productive systems. Doses of 80 t.ha-1 resulted in greater plant height for Chinese onion 24.93 cm and radish 26.27 cm. Lettuce with 40 t.ha-1 had 23.38 cm height. Water coefficients in soils showed variability without determining which biomass dose is better. Chemically, doses of 80 t.ha-1 of cabbage biomass provided more nitrogen that is available, phosphorus and potassium to the soil, without significantly altering the pH.
