Application of special fertilizers and their effects on the agronomic aspects of maize and soil fertility

Maize has a high nutritional requirement, especially regarding NPK fertilization. However, conventional fertilization with these nutrients presents loss potential, mainly by volatilization, leaching, adsorption, and fixation, which may reflect on the development yield of maize plants. Using fertilizers increased efficiency seeks to mitigate limitations, reducing potential losses due gradual nutrient release. This study aimed compare nutrition, growth, production plants subjected different doses special fully applied at planting their residual effect soil. It was randomized block design in 3x4 factorial scheme four replications. The first factor consisted mineral, polymer-coated, organomineral + PGPB fertilizers. second included 0, 60, 90, 120 kg ha-¹ NPK. evaluated vegetative foliar nutrition (N, P, K), growth components, productivity, profitability, K content soil after cultivation. mineral fertilizer produced more dry biomass aerial part. Profitability similar between latter performed better overall productive showing reduction without compromising grain yield, treatment also presented higher
