Abstract

Goat manure was processed initially as tea by steeping the shredded raw material in water for at least 15 days. Further, FGM was prepared by fermenting GMT using molasses at 10% concentration with water. Field bioassay on rice showed that GMT and FGM enhanced plant growth was comparable with the effect of commercial fertilizer at recommended rate (CF@RR), FGM produced vigorous seedlings comparable with the commercial molluscicide used for comparison. Prolonged exposure of the pest to FGM made its effect comparable with that of the commercial molluscicideeniclosamide ethanolamine, after 48 hours. The shredded goat manure (SGM) did not exhibit any biological activity. Insect pest population was higher at the early crop stage and was highly reduced later due to abundance of natural enemies. On tomato production, all treatments did not affect plant height, FGM and GMT at 100% (concentration caused vigorous plant growth at 53DAT. Generally, FGM and GMT controlled cucumber mosaic virus (CMV) and reduced insect pest population consequently, plant damage. The test materials were also friendly to the population of natural enemies. However, yield components indicated comparable effects of the various treatments except on the number of damaged fruits. Generally, GMT and FGM treated plants had less damaged fruits in comparison with tomato applied with commercial fertilizer. This was accounted to the existence of climatic factors beyond optimum levels. The general safety of the processed goat manure products was attributed to the relatively very low microbial counts in FGM and GMT specifically total coliform, aerobic plate and enterobacteria relative to the shredded goat manure.
