Reducing mineral fertilizer use for sustainable agriculture: The influence of seed coating with arbuscular mycorrhizal fungal spores and Leifsonia bacteria on maize (Zea mays L.) and sorghum (Sorghum bicolor (L.) Moench) production

Arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) have been proposed as biofertilizers for sustainable agriculture. Nevertheless, many of the delivery approaches for these beneficial microorganisms have the disadvantage of limited applicability. The study aim was to evaluate the fertilizing potential of seed coating with microbial fertilizers on growth and yield parameters of maize and...

Study of risk factors in adolescence in terms of demographic changes

Adolescence is addressed as a life phase where the prospects for health are tremendous and future patterns of adult health are confirmed. Health in youth is the consequence of communications between prenatal and early childhood development and the precise biological, social-role, and demographical changes that accompany puberty, molded by social determinants, risk, and protective factors that affect the uptake of...

Density and diversity of arbuscular mycorrhizal fungi in Anacardium occidentale L. plantations in Senegal

Cashew nut cultivation plays an important socio-economic role in Senegal. However, it suffers from several problems, including declining soil fertility which leads to low productivity. To overcome these constraints, the use of arbuscular mycorrhizal fungi (AMF) could be a sustainable alternative. However, the positive effects of AMFs may depend on their infectious potential, density, and diversity. So far, little...
