The objective of this may was to evaluate the effect of genotype x environnent interaction and estimative genetic parameters of 205-day adjusted weaning weight observed in four different regions of Brazil. Data consisted of 56039 weight records of Nellore calves raised on pasture and born from 1977 to 1994. Genetic pammeters and expected progeny differences (EPD) were obtained using a sire model simultaneously for the four regions, having sire as randon effects sires and maternal permanent environment of cows and fixed effects sex month and year of birth, farm, and age of dam as covariate. The EPD estimates were obtained. Spearman correlations between EPD'S of different regions were calculated to verify whether the sire ranks were different among regions. The proportion of total phenotypic variance due to permanent environment effect of dam ranged from 0.16 to 0.23. Heritability coefficients were 0.27, 0.33, 0.39 and 0.25 for regions 2, 5, 6, and 8, respectively. Genetic correlations were 0.37, -.06,0.12, 0.36, 0.63 and 0.60. Spearman correlations were 0.60, 0.02, 0.40, 0.55, 0.87, and 0.78 for region pairs 2-5, 2-6, 2-8, 5-6, and 6-8, respectivility. |

he objective of this study was to determine the influence of increasing doses of agricultural gypsum on the quality of the soil biochemical parameters in coffee cultivation (Coffea arabica L.) over two climatic seasons in the Brazilian Cerrado. Soil samples were collected in two seasons (dry and rainy season), at 0.00 ? 0.10 m depth of an Oxisol, submitted to doses 0 (GSA); 3.5 (G3.5); 7.0 (G7.0) and 14 (G14) t ha-1 of agricultural gypsum in the coffee planting line. The biochemical parameters evaluated were: total organic carbon (TOC); microbial biomass carbon (MBC); soil basal respiration (SBR); absolute enzymatic activities [Urease, acid phosphatase, hydrolysis of fluorescein diacetate (FDA)], and enzymatic activity per unit of MBC. The significant effect (p ≤ 0.05) of gypsum doses was observed for MBC and SBR, which were higher in the treatment with G7.0 application. TOC, the enzymatic activities of Phosphatase and the FDA showed no differences between treatments. On the other hand, the specific enzymatic activities by MBC were used to describe the differences between the doses of gypsum applied, generally with greater activity in treatments G7.0 and G14. The accumulated coffee productivity was higher in G14 treatment. The results presented confirmed that the biochemical parameters of the soil are key in the evaluation of changes in soil use, and that the increase in gypsum favors activity and microbial biomass. |
