Evaluation of Macronutrient Content in Frass from Black Soldier Fly Larvae (Hermetia Illucens l.). (BSFL) Treatment of Plant-Dominated and Animal-Dominated Substrates in Port Harcourt. Nigeria

This study was aimed at evaluating the macronutrient content in frass from black soldier fly larvae (Hermetia Illucens l.). (BSFL) treatment of plant- dominated and animal-dominated substrates in Port Harcourt. Nigeria. Its objectives were to determine macronutrient content found in frass from BSFL treatment of plant-dominated and animal-dominated substrates. Between-Group design was employed along with laboratory analysis. Analysis of variance indicated p = .714 for TN, p =.716 for TC, p = .690 for Na, p = .618 for Mg, p =.147 for K, and p = .444 for Ca which were higher than 0.05. and, therefore, there were no statistically significant differences in the means between plant- dominated frass and animal dominated frass for these parameters. However, p = .048 for P was below 0.05. and therefore, there is statistically significant difference in the means between plant-dominated frass and animal- dominated frass for this parameter. It is therefore recommended that depending on plant macronutrients requirements, frass with more macronutrient should be chosen from animal-dominated substrates such as pig and chicken manure.
