CAN COMMERCIAL MICROBIAL INOCULANTS INCREASE GROUNDNUT PHOSPHORUS UPTAKE AND YIELD UNDER LOW NUTRIENT CONTENT SOIL IN SUDAN SAVANNA ?
Abstract :
Groundnut production in Sudan Savanna is threatened by the gradual depletion of soil macro/micro-nutrient due to high population pressure on arable soil and lack of efficient farming system management. In addition, small-scale farmers encounter difficulties in using inorganic fertilizers although their application has a destructive effect on soil resources. Therefore, biofertilizers are beneficial in agricultural practices for environmental safety and sustainability of soil productivity. The aim of this work was to evaluate the effect of commercial arbuscular mycorrhizal fungi (AMF) and rhizobacteria inoculants on groundnut phosphorus uptake and grain yield. Field experiments with three commercial inoculants were carried out during 2010 cropping season in Shanono and surrounding villages in Kano State, Nigeria. The application of commercial AMF inoculant (Rhizatech) showed positive effect in shoot dry weight production (16%), shoot P concentration (2.5 g kg^-1), and pod dry weight (120%). The positive effect of microbial inoculants in increasing groundnut production is promising. Further investigation and mass trial implementation, taking into account soil fertility level in the agroecological zone, are needed to validate the biofertilization technology with small farmers.
