VELECELA, Silvia et al. Microbial enrichment vermicompost under two production system and its effects on radish (Raphanus sativus L.) production. Scientia Agropecuaria [online]. 2019, vol.10, n.2, pp.229-239. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.02.08.

Vermicompost production from livestock manure was evaluated under two production systems through their chemical parameters and evaluating its effect on the growth and yield of radish (Rhaphanus sativus L.) under field condition at the National Agrarian University La Molina, in Li ma - Perú. The experimental design was a complete randomized block design (CRBD) with 12 treatments and three replications. The first factor of study includes two different types of livestock manure that was pre-decomposed under two treatments (washing and inoculation with beneficial microorganism consortium). As second factor, included two kinds of microorganism (Bacillus sp., and beneficial microorganism’s consortium). The third factor included two vermicomposting production system (superficial named "gable roof" and underground "pit system’’) processed with Eisenia foetida during 40 days. The characterization of vermicomposts from the pit system presented greater reduction in salinity, pH, C/N, total phosphorus, potassium, sodium concentration, higher retained moisture, total calcium, magnesium and humic subtances concentration. The C/N value showed that the vermicompost was stable. By comparison, the means indicate that treatment MMZ (livestock manure pre-decomposed inoculate with beneficial microorganism under pit system) attained greater height and length of leaves and individual weight of fruit.
