Impact of pea genotype on yield of subsequently planted corn as mediated by soil microbial communities
Conference Year
January 2022
Abstract
Pisum sativum (pea) is important for humans and livestock and also benefits subsequently planted crops through nitrogen fixation and recruitment of soil microbes that support crop productivity. Since pea genotypes recruit different microbial species, we suspect the benefit to subsequent crops also differs. We grew 108 pea genotypes in pots for 5 weeks, then collected plant biomass and rhizosphere soil for microbial identity analysis. Subsequently planted corn was grown for 12 weeks then harvested for plant biomass. We anticipate corn biomass will differ depending on the pea genotype grown before due to differences in soil microbial diversity and nutrient status.
