The aim of this review article is determined by a reflective analysis of research results, the potential of bio-products as alternative nitrogen sources in plantations onion bulb (A. cepa L.) Allium cepa, according to production volume, is second among the vegetables worldwide. A. Growing Communities strain applied to agroecosystems agrochemicals based treatments, which, brings negative environmental conditions, cause damage to human health and animals, also generates economic unsustainability due to the high prices of synthetic inputs. During the past 20 years, there have been debates and research surrounding the use of agricultural inputs that do not generate losses to agroecosystems, and concluded that the bio-products are an alternative source that supplies nutrient requirements in growing A. strain and lead to considerable productivity with the lowest possible environmental impact. We conclude that produce agricultural bioinputs soil improvements since, contributing favorably in the physical, chemical and biological weapons also allow supplement or replace artificial synthetic fertilizers and thus contribute to the aims of sustainable agriculture.
