Evaluación de un compost maduro y su influencia físico-química en el cultivo experimental de brócoli (Brassica oleracea L.)

Abstract

This investigation was conducted in the province of Azuay, canton Gualaceo, in the neighborhood of Bullcay of Experimental Stationbelonging totheAustroAutonomous Instituteof Agricultural Research (INIAP); for the implementationand evaluationof maturecompostandits physico-chemical influence on the experimental cultivation of broccoli (Brassica oleracea L.), based in a Design Randomized Complete Block with three replicates for treatment. The different treatments applied consist of compost developed and produced under similar conditions between them, especially in the content of their raw materials (mainly crop residues) plus the addition of different manures or excreta, such as: cattle, guinea pig, pig, horse, chicken mix of manure and chicken with inoculum, chemical and absolute control too; mainly analyzed physicochemical parameters, such as: pH, % organic matter and Cation Exchange Capacity, resulting values of pH higher than the point of starting (7,90) in all treatments, an increase of % organic matter from 0.59% to an average of 2.50%, having similar ranges in all treatments and in Cation Exchange Capacity presented values with major differences they began as a value of 27.41 meq/100 g of soil and these increased approximately 10 meq/100g in treatments that containing compost, takingthe maximum valuethetreatmentT5 with 39.20 meq/100g it is thecompost with chicken manure, and chemical and absolute control present lower values.
