          Abstract

          El presente trabajo evalúa el comportamiento de la lombriz roja (Eisenia spp.) en dos ambientes (Carpa Solar y Ambiente Natural) utilizando como sustrato dos tipos de residuos sólidos orgánicos (Estiércol Vacuno = EV y Restos de Cocina = RC) en Predios de la Estación Experimental de la carrera de Ingeniería Agronómica de la Unidad Académica Campesina Carmen Pampa, Dependiente de la Universidad Católica Boliviana, en la Comunidad Carmen Pampa, Nor Yungas, Departamento de La Paz. Se adoptó un diseño bifactorial con tres repeticiones y los datos se sometieron al análisis de varianza (ANVA). El mayor número de cápsulas (cocones) se obtuvo en el ambiente Carpa Solar siendo para EV de 64 y RC de 41 cápsulas. En cuanto al porcentaje de eclosión, en el ambiente Carpa Solar se registró 100% de eclosión en EV y 96% en RC. Por consiguiente, el mayor número de lombrices nacidas ocurrió en el ambiente Carpa Solar, siendo 2 lombrices por cápsula para EV y 3.5 lombrices por cápsula para RC. La mayor tasa de crecimiento de lombrices inmaduras (no cliteladas) se presentó en el ambiente Carpa Solar resultando para EV de 123 individuos y RC de 16 lombrices. Por lo tanto, la menor tasa de mortalidad entre ambientes se produce en ambiente Carpa Solar con 3.90% de mortalidad para EV y RC con 88.64%. Por otro lado, el mayor número de lombrices cliteladas se encuentra en Ambiente Natural siendo en EV de 15 individuos y RC con 21 lombrices cliteladas. En cuanto a la biomasa de lombrices no cliteladas, el mejor resultado se registró en ambiente Carpa Solar obteniéndose para EV 1.41 g y para RC 0.185 g. Sin embargo, la mayor biomasa total de lombrices cliteladas se obtuvo en RC 7.98 g para el ambiente Carpa Solar frente a 6.93 g en el Ambiente Natural. El grado de fitotoxicidad del vermicompost obtenido de EV en los dos ambientes fue bajo, presentando 66.6% de germinación, ya el producto obtenido de RC presentó mayor fitotoxicidad en ambos ambientes. Con respecto al análisis de macronutrientes en los vermicompost obtenidos, se determinó un contenido de 2.45 y 2.31% de nitrógeno; 500 y 220 mg kg-1 de fósforo; 27.43 y 2.76 cmol (+) kg-1 de sustrato seco en los sustratos RC y EV respectivamente.

          This work evaluates the behavior of the vermicomposting red worm (Eisenia spp.) in two environments (greenhouse and unsheltered) and with two solid organic substrates (cow manure=CM and kitchen waste=KW) in the zone of Carmen Pampa, Nor Yungas Province, Department of La Paz - Bolivia, using a factorial design with two factors and three repetitions (ANOVA analysis). The largest number of cocoons was found in the greenhouse treatment, with 64 in CM and 41 in KW. Cocoon viability was also greatest in the greenhouse treatment, at 100% for CM and 96% for KW. Similarly, the greatest number of worms hatched from cocoons was in the greenhouse treatment, with 2 immature worms for CM and 3.5 for KW, and the greatest number of immature worms was registered in the greenhouse treatment with 123 individuals in CM and 16 in KW. The lowest mortality rate due to environment was in the greenhouse treatment, with 3.90% mortality with CM and 88.64% with KW. The greatest number of mature worms (with clitella) was in the unsheltered treatment, with 15 in CM and 21 in KW. The greatest biomass of immature worms was found in the greenhouse treatment, with 1.41 g of worms for CM and 0.185 g for KW; however, the greatest biomass of mature worms was in the KW treatment, with 7.98 g for the greenhouse treatment and 6.93 g for the unsheltered treatment. The phytotoxicity from CM vermicompost in the two environments was lowest, exhibiting a 66.6% rate of germination, and the opposite was true for KW, which was the most toxic in both environments. Macronutrient content in vermicompost obtained was: nitrogen at 2.45% and 2.31%, phosphorus at 500 mg kg-1 and 220 mg kg-1 and potassium at 27.43 and 2.76 cmol(+) kg-1 of dry substrate in KW and CM respectively.
