Abstract: Improper disposal of agricultural waste and soil nutrient deficiency are major issues in Nigeria, leading to a heavy reliance on chemical fertilizers for crop growth. Consequently, the objective of this paper was to produce biofertilizers using plant growth-promoting bacteria from cassava peels and plantain leaves to evaluate the effects on growth parameters of Beans (Phaseolus vulgaris L.) and Groundnut (Arachis hypogaea L.) seeds using appropriate standard microbial and agro-techniques. The effects of each treatment were examined on various growth parameters of beans and groundnuts for 20 days, including shoot length, leaf length, leaf number, leaf width, stem girth, and number of branches. Plantain leaves had higher concentrations of magnesium and nitrogen, while cassava peels had more phosphorus and potassium. On day 20, the highest shoot length (39 cm), leaf width (7.2 cm), and largest stem girth (2.5 cm) for beans were observed in soils treated with CP+PL+ B. pumilus, CP+PL+ S. maltophilia, and CP+PL+B. pumilus+ S. maltophilia, respectively. For groundnuts, the highest shoot length (22 cm), leaf width (3.5 cm), number of leaves (60), and number of branches (16) were observed in soils treated with CP+PL+ B. pumilus + S. maltophilia, CP+PL+B. pumilus, CP+PL+S. maltophilia, and CP+PL+ S. maltophilia, respectively. The results showed that there was a significant difference in the treatments and the duration of the treatments at a 5% level of significance. The growth parameters of beans and groundnut plants revealed that using B. pumilus or S. maltophilia as single-strain biofertilizers or in a consortium improved the plants' growth. The study recommends the production of commercial biofertilizers from common agricultural waste to promote sustainable agriculture and entrepreneurship among microbiologists.
