Maize crop response to different levels of mineral and or-ganomineral fertilization associated with plant growth promoting bacteria (PGPBs)

Corn has a high nutritional requirement, especially with regard to NPK fertilization. However, the low efficiency of conventional fertilizers combined cost input limited reach yields. The use increased seeks mitigate these limitations, reducing potential losses due gradual release nutrients. objective this work was compare nutrition, growth and production maize plants subjected different doses special fully applied at planting, as well their residual effect on soil. A randomized block design used, in 3 x 4 factorial scheme, four replications. first factor consisted mineral, polymer coated organomineral inoculated PGPBs. second 0, 60, 90 120 kg ha-¹ NPK. Vegetative growth, foliar nutrition (N, P K), yield components, productivity, profitability K nutrient content remaining soil after cultivation were evaluated. mineral fertilizer presented higher dry biomass aerial part relation fertilizers. better results vegetative productive general, still showing reduction doses, without compromising grain yield, fertilization + same showed greater soil, proving be relevant longterm studies for elucidation effects subsequent culture.
