MUNOZ C, JUAN MANUEL; MUNOZ P, JAVIER ANDRÉS  and  MONTES R, CONSUELO. EVALUATION OF ORGANIC MANURES IN LETTUCE AND CABBAGE PLANTS AT POPAYÁN, CAUCA. Rev.Bio.Agro [online]. 2015, vol.13, n.1, pp.73-82. ISSN 1692-3561.

This study was realized to evaluate organic manures from residues of crop and markets at Popayán's city, using cabbage and lettuce plants. There were gathered residues of productive units of coffee and principal markets of the city, batteries of compost were elaborated for separated and every compost was analyzed to determine the content of nutrients. The Compost was applied in two stages of culture as alternative to chemical fertilization. Statistical experimental design was completely at random with three treatments and three repetitions, T₀: Witness, without any credit; T₁: elaborated compost of flesh of coffee, stem of banana and poultry droppings and T₂: compost obtained from residues of market. The physicochemical tests met compost NTC 5167 boundaries and the difference was that T₁ is a source of K and P, while T₂ is N source; compost application in improved soil pH, content of MO and CIC, the average weight gain for cabbage and lettuce exceeded 300%, it not was necessary to provide pest control measures; microbiological test INVIMA met the parameters for quality control and monitoring of foodstuffs. It was concluded that the materials used for compost production influence the physicochemical properties of organic manures and composting met analyzed 15 parameters of the NTC 5167.

Keywords : Compost; Crop residues; Infestatión; Fertilizatión; Lactuca sativa; Brassica oleracea.
