Produtividade e qualidade de espigas e de sementes de milho crioulo produzidas em diferentes doses de biofertilizante suíno

Abstract

Due to the great importance of the maize culture in Brazil and looking for the use of swine wastes as an organic fertilizer, this work analyzed the production, productivity and quality of maize landraces seeds, cultivated with different doses of swine biofertilizer. Five doses of swine biofertilizer (0, 50, 100, 150, 200%, based on the phosphorus recommendation for the maize crop) were used, in randomized blocks with four replications. Parameters related to the corn productivity and the seed quality were evaluated. The results showed that the swine biofertilizer significantly altered the stem diameter and the plant height, but did not affect the grain yield and other production components. There is a need to conduct further studies about the agricultural use of swine biofertilizer to complement the work, such as the use of higher doses and a different distribution of the swine biofertilizer.
