“…The CART models proved that SOC level was the main parameter determining soybean yield in the farmers' field. The importance of SOC level on crop yield and soil fertility was largely reported [19,20,21]. However, in the two AEZ, farmers do not apply manure in their fields especially for soybean cultivation.…”

Soybean is a food security crop in Benin due to its high nutritional value but its yield in the farmers’ cropping system is very low. The present study aims to provide appropriate response to the yield variability among fields in two agro-ecological zones of Benin namely: Southern Borgou zone (AEZ 3 in the north) and cotton zone of central Benin (AEZ 5). Soil samples were collected from 0-20 cm depth in 120 fields (50 in the AEZ 3 and 70 in the AEZ 5). pH (water), soil organic carbon (Walkley and Black method), total nitrogen (Kjeldahl method), CEC (0.01 N ammonium acetate at pH 7 method) and available phosphorus (Bray 1) were determined in the laboratory of Soil Science Water and Environment (LSSEE) of the National Agricultural Research Institute of Benin (INRAB). Cropping system (crop rotations, soil fertility management practices) were also collected using an open ended questionnaire. Classification and regression trees (CARTs) models were used for data analyses. Soybean yield variability among the agro-ecological zones were registered and the highest yield recorded was less than 1 t.ha-1. Considering soil characteristics, soil organic matter level was the most important variable determining yield variability. Furthermore, quantities of P applied and farmyard manure were cropping practices inducing yield variability (86.4% and 15% of the variability respectively). Our results also show that, yield differences noticed among the agro-ecological zones were induced by CEC and pH (water). The study suggested promotion of integrated soil fertility management practices to sustain soybean yield in the study area.

“…This could be explained by the transportation costs of the manure, availability on the manure and the use of crop residues to feed the animals. The consequence of such practice is the decrease of soil organic carbon level and in long-term induce adverse effect on soil productivity [19].…”

“…Le résidu d'élevage peut ensuite être utilisé comme un bio fertilisant de qualité pour améliorer la qualité des sols, augmenter le rendement des cultures et réduire l'utilisation d'engrais chimiques (16,20,21,22,69,71). Les teneurs en oligoéléments des résidus produits à partir des différents substrats de production d'asticots ont été comparés (15). Les substrats produits via la dégradation des asticots sont susceptibles d'être utilisés en agriculture (tableau 3).…”

L’alimentation de la volaille nécessite un apport essentiel en protéine. Ces protéines sont introduites aux animaux à travers des ingrédients alimentaires comme les légumes à graines et leurs tourteaux (arachide, soja, etc.), les farines de poisson, etc. Ces sources protéiques bien qu’étant indispensables en alimentation de la volaille, sont assujetties à une flambée de prix et sont peu ou pratiquement non durables. Les asticots des mouches constituent une solution durable en alimentation animale mais sont classées dans les sources méconnues de protéines animales en Afrique de manière générale et au Niger en particulier. La production de ces asticots n’est pas onéreuse et n'implique pas pour le moment une compétition alimentaire avec l’alimentation humaine. Les asticots des mouches domestiques (Musca domestica L. 1758) et des mouches soldats noires (Hermetia illucens L. 1758) sont privilégiés en raison de la facilité de leur production et de l’importance de leur biomasse. Les larves de ces deux types de mouches sont souvent produites avec des déchets de toute nature (substrats) disponibles gratuitement ou cédés dans le cas marchand à un prix dérisoire. Les compositions chimiques de ces asticots sont similaires voire meilleures que celles des ingrédients alimentaires conventionnels utilisés en alimentation avicole, et leur utilisation dans l’alimentation de ces volailles induit de bonnes performances zootechniques aux animaux. En plus de la protéine, le processus de production d’asticots permet d’un coté de recycler les déchets organiques qui constituent un véritable problème environnemental et de l’autre côté il permet de générer un résidu biofertilisant riche en nutriment qui peut être valorisé en agriculture. Plusieurs études ont montré qu’il n’a pas de dans danger sanitaire lié à l’utilisation des asticots en alimentation animale en général et celle de la volaille en particulier. En effet l’évaluation de plusieurs éléments-traces métalliques (ETM) au niveau des asticots avait révélé ces ETM sont à des seuils inferieur à ceux recommandés par les organismes internationaux (Union Européenne, organisation mondiale de la santé). Quelques rares études ont affirmé qu’une transmission de Salmonelles est possible aux consommateurs. Toutefois il est admis à l’unanimité que les asticots peuvent être introduits en alimentation animal sans induire des effets néfaste sur leur santé et que les contaminations éventuelles sur toute la chaine alimentaire peuvent être contrôlées.

“…The recycling of waste and the production of protein are two of many benefits in using insects for waste treatment. The use of insects also generates a residue that is rich in minerals, which can be valorized as a quality bio-fertilizer to improve soil quality, enhance crop yield, and reduce the use of chemical fertilizers [21][22][23][24][25]. Furthermore, this residue can be used to produce secondary industrial compounds (e.g., biofuel, lubricants, pharmaceuticals, dyes) [26].…”

The amount of waste produced by the population creates general health problems in terms of public health and hygiene. In recent years the common housefly (Musca domestica L. 1758; Dipteran: Muscidae) has been widely used in the treatment of organic wastes. This study aims to assess the effect of egg loading of the common housefly on maggot development and waste reduction. Housefly larvae were reared at four egg loads (1.25, 2.5, 5, 10 mg) under three different diets (wheat bran, millet bran, cow dung). Two-factor ANOVA (α = 0.05) was used to test the effect of two fixed factors (egg load and substrate) on larval biomass, the survival rate from egg hatching until the last larval instar, number of larvae and substrate reduction rate. The comparison of means based on Duncan’s test was performed to compare the means of the different variables measured. Principal component analysis (PCA) was used to determine the relationship between the measured variables (larval biomass, the survival rate from egg hatching until the last larval instar, number of larvae, and substrate reduction rate) on the discrimination of the egg load factor. The results showed that under the same nutritional conditions, the yield of housefly larvae, the number of larvae and the reduction of substrates increased with increasing egg load. Indeed, at each of three substrates, the rearing egg load of 10 mg resulted in the maximum larval yield, maximum number of larvae, and maximum substrate reduction rate. At this optimum load, wheat bran generated greater biomass, greater number of larvae and greater reduction of substrate compared to millet bran and cow dung. The egg load as a whole had no effect on the survival rate from egg hatching until the last larval instar, unlike substrate type. The high egg load for the survival rate (from egg hatching until the last larval instar) for millet bran was 1.25 while there was no difference for the other two substrates. These results can help to make the waste treatment process efficient with the subsequent production of a large larval biomass that can serve as added value in animal feed. The egg load of 10 mg and the wheat bran were superior respectively to the other egg load and substrates type for all parameters tested excepted for the survival rate (from egg hatching until the last larval instar). Ours study indicated that larval biomass, larval number, egg viability and substrate rate reduction of Musca domestica are affected by the egg load, substrate type and their interaction.
