Inoculation of <i>Rhizobiums sp</i> Strains to Improve Soil Fertility: A Peanut Trial in Covè and Ouessè (Benin)

Abstract

Thought the increasing demand Arachis hypogaea L. (groundnut), its yields remain low with increasingly using chemical fertilizers. To reduce the costs for chemical fertilizers inquisition and their long-term toxic effects on soils, microbial bio-fertilizers could be an accessible alternative to peanut farms. Thus, the aim of this study was to assess the performance of rhizobia strains on peanut varieties production. The experiments were conducted in two agro-ecological zones of Benin, in a peasant environment peasant-researcher control or under peasant and researcher control. The experimental device used was a complete random block with nine repetitions and two factors namely inoculation (with Rhizobium sp and without Rhizobium sp) and mineral fertilizer (with N 15 P 15 K 15 and without N 15 P 15 K 15). The effects of these factors divided into four treatments were evaluated on the plants vegetative, symbiotic and production parameters. In addition, an evaluation of each treatments' comparative advantages was carried out. The results showed that How to cite this paper:

Long-term fertilization coupled with rhizobium inoculation promotes soybean yield and alters soil bacterial community composition

“…Combination of Rhizobium sp. and chemical fertilizer (N 15 P 15 K 15 ) achieved the best peanut nutrition and production parameters ( Adjile et al, 2020 ). Rhizobium has been demonstrated to be an environmentally friendly substitute to nitrogen fertilizer based on the positive effects above ( Gitonga et al, 2021 ; Halwani et al, 2021 ; Pires et al, 2021 ; Kumawat et al, 2022 ).…”
