Résumé

Crop agronomic performance are mostly related to the agricultural practices used for production. Study was carried out at Kamboinsin, in Burkina Faso, with aim to evaluating the effects the fertilization and planting density on mung bean (Vigna radiata) agronomic performance. The fertilization was at three (03) levels of treatment (control, NPK (14-23-14) and poultry manure), the planting density at three levels (D1:177,777; D2: 133,333 and D3:106,666 plants ha-1) and the genotype at two (02) levels (Beng tigre, M3). The experimental design was a split-split-plot replicated thrice. Growth, yield components and yield related data were collected and subjected to amultifactorial analysis using JMP 16.1.0 version software. Significant means were separated using Student Newman Kheuls’s test at 5% threshold. The results showed that fertilizing with organic matter resulted in the highest number of branches per plant, leaf chlorophyll content, number of pods per plant, pod weight per plant, pod yield per hectare, number of grain per pod, hundred grains weight, grain weight per plant, grain yield per hectare and harvest index. The mineral fertilization (NPK) was more favorable to a high aerial biomass. The lowest performance were registered from the control. Plants were highly performing under the planting density D1 (177,777 plants ha-1). Decreasing plant population densities led to a progressive decrease in agronomical performance of mung bean. Beng-tigre is the most grain productive and recommendable compared to the M3 genotype. The type of fertilizer, the planting density and the genotype have significant influence on mung bean production.
