Abstract
La Investigación se realizó en el Fundo Pinit, caserío de Pichampampa. A una altitud de 2641 m.s.n.m. La precipitación pluvial fue de 786.6 mm. año-1, con una temperatura máxima de 17.62 °C, temperatura mínima de 7.64 °C y humedad relativa de 71.65% en el periodo experimental del mes de junio al mes de octubre. El objetivo fue determinar el efecto de tiempo del precompsotaje en el crecimiento poblacional de Eisenia foetida “Roja Californiana” en Otuzco, La Libertad. Se evaluaron precompostajes de 1, 2, 3 y 4 semanas en un diseño de Bloques Completos al Azar con cuatro repeticiones. Las unidades experimentales estuvieron conformadas por cajas de madera conteniendo 20 dm3 de precompost elaborado en base a estiércol de vacuno y aserrín en proporción 1:1 en volumen sembrada con 40 lombrices al inicio del experimento. Las variables evaluadas fueron: número y peso de huevecillos, juveniles y adultos a los 15, 30, 45, 60 y 120 días después de la siembra. No se encontraron diferencias estadísticas significativas para las variables evaluadas en ninguno de los momentos de muestreo. Se concluye que tanto el peso de los individuos como su tasa de reproducción no son influenciados por el precompostaje de diferentes edades.
ABSTRACT The investigation was carried out in the Fundo Pinit, village of Pichampampa. At an altitude of 2641 m.s.n.m. Rainfall was 786.6 mm. Year-1, with a maximum temperature of 17.62 ° C, a minimum temperature of 7.64 ° C and relative humidity of 71.65% in the experimental period from June to October. The objective was to determine the time effect of the pre-compost in the population growth of Eisenia foetida “Roja Californiana” in Otuzco, La Libertad. Precompostings of 1, 2, 3 and 4 weeks were evaluated in a Random Complete Block design with four repetitions. The experimental units were made up of wooden boxes containing 20 dm3 of precompost made from bovine manure and sawdust in a 1: 1 ratio in volume sown with 40 worms at the beginning of the experiment. The variables evaluated were: number and weight of eggs, juveniles and adults at 15, 30, 45, 60 and 120 days after sowing. No significant statistical differences were found for the variables evaluated at any of the sampling moments. It is concluded that both the weight of the individuals and their reproduction rate are not influenced by the precomposting of different ages.
