The aim of this study was to predict Jatropha curcas plant yield through an Artificial Neural Network (ANN) Multi-Layer Perceptron (MLP) model. The predictive ability of the developed model was tested against the Multiple Linear Regression (MLR) using performance indexes. According to the performance indexes the use of ANN-MLP model improved Jatrop...

The demographic pressure in Benin has led to an increase in demand for cereals, in particular maize (Zea mays L.), which constitutes the staple diet for the populations. Yet, in this context of climatic variability, the environmental conditions greatly limit the yields of this crop. The purpose of this study was to compare the agro-morphological ch...

Larvae of black soldier fly (BSF), Hermetia illucens (L.1758) (Diptera: Stratiomyidae), are increasingly being used as animal feed ingredients. Larvae are usually produced by placing eggs, obtained from adult rearing on growing substrates but can also be obtained by exposing substrates to naturally occurring BSF females. In the latter system, the s...
