Since sericulturists in the Cauca department replaced inorganic fertilization with organic fertilization, mulberry leaf production has decreased due to the poor quality of the compost applied and the lack of knowledge of the contributions that these make to the soil. Therefore, it was proposed to evaluate the effect of organic fertilization on the yield and diversity of rhizospheric bacteria in the mulberry crop (Morus alba), in the Clarete Alto area located in Popayán, using a randomized block design with five treatments: a control, three doses of compost (0.25, 0.5 and 1.0 kg m2) and inorganic NPK, applied to the soil. It was determined that the highest yield of biomass and mulberry leaf was obtained with NPK and with the highest amount of compost applied, likewise, the highest averages of the percentages of windability, bark and thickness were achieved in the bud with these same treatments. Regarding the bacterial diversity of the compost used, Proteobacteria, Firmicutes and Actinobacteria were identified as the dominant phyla, and in the soil cultivated with mulberry it was found that the application of compost generated pH increases between 0.7 and 1.4 units, which modified the bacterial diversity expressed in its composition, richness and structure at the order, family and genus level. It was also identified that Proteobacteria, Acidobacteria and Actinobacteria were the most dominant phyla.

Since the caucasians sericulturists replaced inorganic fertilization by organic, leaf production has decreased, due to the poor quality of applied composting and ignorance of the contributions they make to the soil, so it was proposed to evaluate the effect of organic fertilization in the yield and diversity of rhizospheric bacteria of the mulberry cultivation (Morus alba), in the village of Clarete Alto located in Popayán, using a randomized block design with five treatments: control, three doses of compost (0.25, 0.5 and 1.0 Kg.m2-1) and inorganic NPK applied to soil. From the crop it was determined that the highest yield of biomass and mulberry leaf was obtained with the NPK and with the highest amount of compost applied, in the same way, from the cocoon of the cocoon the highest averages were reached it was obtained the highest percentage of yield and bark percentages, as well as the greater average thickness of the cocoon, with the application of NPK and the greater amount of compost. Regarding the bacterial diversity of the compost used, Proteobacteria, Firmicutes and Actinobacteria were identified as dominant phylum, and in soil grown with mulberry it was found that the application of compost generated pH increases between 0.7 and 1.4 units, which modified the bacterial diversity expressed in its composition, richness and structure at the level of order, family and gender, it was also identified that Proteobacteria, Acidobacteria Verrucomicrobia and Actinobacteria were the most dominant phylum.
