The Santa Inês is a breed of American Hair sheep found in Brazil. It is generally thought to be a cross of Morada Nova, the course-wooled Italian breed, Bergamasca, and the native coarse-wooled Crioula followed by a period of selection for absence of fleece. The Santa Inês also resembles the Sahelian types of hair sheep from the arid regions of west Africa. Their colors range from red, black and white and can be spotted or solid, showing a lack of genetic homogeneity of this breed, which is still in formation. This study aims to estimate environmental effects on production and reproduction traits for Morada Nova, Santa Inês and their crossbreds in Central Brazil. There is a need to determine the genetic structure of the Santa Inês before the closure of the herd book as its dominance of the hair breed meat market may be due to a large degree of heterosis due to the fact that it is still in formation. |

The nitrogen (N) utilization by maize grown in a no-tillage system is dependent on the quality of the preceding crop residues, which may promote differences in N fertilization efficiency with respect to time. Thus, the purpose of this study was to evaluate the nutritional state, dry matter production and grain yield of maize grown in a clayey soil (Typic Acrustox) under a no-tillage system. The split-plot experimental design was set up in randomized complete blocks with three replications, in which the main plot was treated with different N application strategies and the split-plots were planted with winter crops (soybean and maize). The fertilizer strategies (rate: 120 kg ha-1 of N) used were as follows: (0 ? 0), (20 ? 100), (60 ? 60), (120 ? 0) and (0 ? 120), with the first number corresponding to the rate of N (kg ha-1) applied before planting and the second number corresponding to the top dressing rate (V4-5 stage). Nitrogen fertilization raised the N content (in shoots and leaves) and maize yield (in the shoot dry matter and grain). The maize grown after soybean had both greater N concentrations and production (dry matter and grain) relative to the maize grown after maize. Applying 120 kg ha-1 N did not significantly affect the evaluated variables, regardless of the winter crop. |
