Abstract Purpose: It is urgent to mitigate the environmental impacts resulting from agriculture, especially in highly biodiverse and threatened areas, as the Brazilian Cerrado. We aim to investigate whether phosphatase activity and mycorrhizal colonization are alternative plant strategies for nutrient acquisition in maize cultivated under fertilized and unfertilized conditions in Brazil, potentially contributing to reduce the use of phosphate fertilizers needed for production.Methods: Three experiments were performed: the first was conducted in a glasshouse, with 17 experimental pure maize lineages and two phosphorus treatments; the second in the field, with 3 pure maize lineages and two treatments, one without fertilization and another with NPK fertilization; and the third was also carried out in the field, with 13 simple commercial hybrids, grown either under NK or under NPK treatment. Soil and plant variables were measured and tested for the response to fertilization, differences amongst genotypes and response to phosphatase activity and mycorrhizal colonization.Results: We detected a positive effect of mycorrhizal colonization upon growth in pure maize lineages. The activity of acid phosphatase was modulated by the availability of phosphorus and nitrogen in the soil, and promoted grain filling of commercial hybrids in soils with low phosphorus availability. Conclusions: These results demonstrate, for the first time, that it is possible to select genotypes that are more adapted to low soil phosphorus availability aiming at organic production, or to use genotypes that have high phosphatase activity under phosphorus fertilization to reduce the amount of added phosphorus needed for maize production in Brazil.

ABSTRACT: Onion is an important vegetable crop, predominantly grown under conventional tillage system management. Alternatively, the vegetable no-tillage system uses cover crops to form a residue layer, which improves soil physical, chemical, and biological attributes. Aiming to understand the interaction of mycorrhizal and non-mycorrhizal cover crops, phosphatase activity, and soil phosphorus availability and uptake by plants, a no-tillage vegetable production system experiment with onion was carried out in Ituporanga, Southern Brazil. The treatments were black oats (Avena strigosa); rye (Secale cereale); oilseed radish (Raphanus sativus); rye + oilseed radish; black oats + oilseed radish, and a control with spontaneous plants. Additionally, two plots, a conventional tillage system area and a forest, both adjacent to the experiment, were evaluated. We measured cover crop biomass, onion yield, acid phosphatase activity, and resin-extracted phosphorus in the soil, shoot and root phosphorus content, and root colonization in cover crops, spontaneous plants, and onions. The treatments with cover crops had the highest plant biomass in winter and onion yield. Available soil phosphorus and acid phosphatase activity were higher in no-tillage plots than in the conventional tillage system area. The presence of non-mycorrhizal oilseed radish was associated with decreased colonization of rye and onion roots by arbuscular mycorrhizal fungi. No-tillage areas with cover crops or spontaneous plants in winter accumulated more phosphorus than conventional tillage system areas. The conventional tillage system showed adverse effects on most soil attributes, as shown by a Principal Component Analysis.
