Vermicompost as a Biofertilizer: Effects on Growth, Productivity and Nutritional Quality of Common Bean (Phaseolus vulgaris L.) in Burundi

Résumé

Soil degradation, soil acidity, and low crop productivity and nutrient content pose major challenges to food security. This study aims to evaluate the effect of vermicompost on the growth, productivity, and nutritional quality of beans. The cultivation was carried out in fields with four complete randomized blocks, each block comprising four treatments: 140 g of vermicompost, 210 g of vermicompost, chemical fertilizers, and a control. Sowing was carried out uniformly, with a sample of 112 plants selected to measure growth parameters (height, number of leaves, flowers, buds, pods) and productivity. Nutrient content analyses (proteins and total sugars) were carried out at the laboratory of the Institute of Agricultural Sciences of Burundi (ISABU). Bar charts were used to represent discrete data, and one-way analysis of variance was used to compare height and productivity by fertilizer type. A multiple linear regression model was applied to explain bean productivity. The analyses were performed using R software (Version 4.1.2.). The results show that treatment with 210 g of vermicompost significantly improves growth, with a greater number of leaves, buds, and flowers, compared to other treatments. Analysis of variance reveals a significant effect of fertilizer type on height and productivity. Although vermicompost did not increase protein content, it significantly increased total sugars in beans. In conclusion, this research highlights the value of vermicompost as an amendment to improve the growth and nutritional quality of beans.
