EVALUATION OF AQUATIC LILY (Eichhornia crassipes) AND AGRICULTURAL WASTES FOR PRODUCTION OF OYSTER MUSHROOM

The production of the CP-50 strain of Pleurotus ostreatus in water lily (Eichhornia crassipes) was evaluated in comparison and combination with some agricultural residues of the region Valsequillo, Puebla. The water lily was collected in the Manuel Ávila Camacho dam in the municipality of San Pedro Zacachimalpa to be used in the cultivation of the CP-50 strain under controlled conditions. An experimental random block design was carried out with a total of 240 production units. The highest biological efficiency (EB) is for the corn stubble treatment (136.6%) and the MLA treatment (120.6%), the lowest EB was for the LA treatment with 12.3%. The bromatological analyzes showed that the water lily can increase the crude protein content of the sporomes, where the highest percentage was obtained in the LA treatment with 32.6% and an energy value of 267.20 Kcal / 100 g. Additionally, it was demonstrated in the tests for heavy metals that the consumption of mushrooms grown on substrates supplemented with E. crassipes does not present food toxicity, since they comply with the parameters of the FAO Codex Alimentarium. The production of mushrooms was favored when using E. crassipes in agricultural residues such as barley straw and corn stubble, which represents an excellent option for the production of high protein food and for a more adequate management of aquatic lily within of the Manuel Ávila Camacho dam, Puebla.
