1. Impact of nitrogen fertilization on the forage characteristics and beef calf performance on native pasture overseeded with ryegrass
The overseeding of ryegrass (Lolium multiflorum Lam) on sub-tropical native pastures increases the availability and quality of forage in the cold season. However, soil chemical amendment and nitrogen use can affect the floristic composition, with consequences to the primary and secondary production. In a randomized complete block design with three replicatio

2. Productivity and reproductive performance of grazing beef heifers bred at 18 months of age
The experiment was carried out to evaluate the performance and body development of beef heifers reared from 15 to 18 months of age on Pearl millet (Pennisetum americanum), Alexandergrass pasture (Urochloa plantaginea) or native pasture invaded by Annoni-2 grass (Eragrostis plana Nees). The experimental design was completely randomized following a repeated me

3. Fertilization and oversowing on natural grassland: effects on pasture characteristics and yearling steers performance
The objective of this study was to evaluate the vegetal and animal production of a natural pasture on a Mollisol soil in the region of Campanha, in RS. The experimental design consisted of complete randomized blocks with three replicates, which enables the comparison between natural unfertilized pastures with fertilized pastures and pastures fertilized and o

5. Performance of nellore cattle under two grazing management systems.
The objective of this study was to evaluate the effects of grazing intensification on birth weight (BW), weaning weight (WW, standartized to 205 days), average daily gain weight (BW), weight (ADG), and gestation length (GL) of calves, cow weight at at weaning (CCW), and BW/CWC (BWR), WW/CWC (WWRC) and WW/CWW (WWRW) ratios. One hundred and sixty eight nellore

6. Pruning cycles and nitrogen fertilization of coffee feilds conducted in the "safra zero" system.
Modern, competitive and cost effective coffee production requires plants with high productivity that are more adapted to mechanical and manual harvesting. ?Safra Zero? is a cultivation system designed to limit plant height and eliminate the need for expensive harvesting during years of low productivity, which usually follow years of high productivity. This s
