Abstract
The objective of this work was to evaluate the effect of different doses and modes of application of piggery waste in the early development of maize plants. The experiment was carried out in a greenhouse using a randomized block experimental design, with treatments arranged in a 6x2 experimental scheme. Factors consisted of six doses of piggery waste (0, 20, 30, 40, 50 and 60 m-3 ha-1) and two modes of application (incorporated into the soil and placed on the surface), with four replications. The following characteristics were evaluated during the experiment: plant height, stalk diameter, fresh and dry weight of shoots and roots, and root volume. Piggery waste doses led to increases in all analyzed variables, but no statistical difference was found between the modes of application, which indicates that applying the waste on the surface or incorporating it into soil did not result in significant agronomic changes. Key words: Organic fertilizing, Zea mays, animal waste.
Highlights
Maize is a monocotyledon plant, belonging to the family Poaceae, genus Zea, and scientifically named Zea mays L. (Fanceli and Lima, 1982)

Summary
Maize is a monocotyledon plant, belonging to the family Poaceae, genus Zea, and scientifically named Zea mays L. (Fanceli and Lima, 1982). Due to their high nutritional value, its grains are used in human and animal diets, and serve as raw material for industry (Buzetti et al, 2009). In Brazil, the average grain yield of maize crops is considered low when compared to those of other producing countries In most cases, this loss may be linked to fertility factors (lack of nutrient replacement) and soil density (Rizzardi et al, 1994). This loss may be linked to fertility factors (lack of nutrient replacement) and soil density (Rizzardi et al, 1994) This is often due to the high cost of industrialized mineral fertilizers and the incorrect use of organic waste generated in rural properties. To Costa et al (2000) the use of piggery waste in agriculture can result in savings and financial
