Abstract
The present concern about environmental degradation has produced a renewed interest in organic fertilizers, such as animal manures. In addition, the soil organic matter conservation is one of the most important limiting factors for sustainability development in semiarid regions. In a previous experiment, carried out to evaluate the direct effects of application of manure rates in corn, positive effects of this fertilization were observed on green ear yield and grain yield. It was also verified that manure increased water retention and availability, and phosphorus, potassium, and sodium contents in the soil layer from 0-20 cm, but did not influence pH, calcium, organic matter contents and the sum of bases. The objective of this work was to evaluate the residual effect of applied fertilization on green ear yield and grain yield in cultivars AG 9012 and AG 4051. In both cultivars, a lack of manure residual effects was verified on total number and weight of green ears; number and weight of marketable ears, either unhusked or husked; plant height and ear height; fresh and dry matter in the above-ground part; and grain yield and its components. Cultivar AG 9012 performed best with regard to characteristics employed to evaluate green corn yield, and cultivar AG 4051 was superior with reference to plant height and 100-grain weight. The cultivars were not different with respect to the other traits evaluated.
