| The objective of this research was to evaluate the effects of tiller age on morphogenic and structural characteristics of guinea grass cv. Mombaca subjected to intermittent stocking and three stubble heights: 30 cm, 50 cm and 50-30 cm. Stubble heights were assigned to experimental units in a completely randomized block design with three replicates. Grazing was performed when canopy intercepted 95% of light incidence. Leaf appearance rate, leaf elongation rate and number of live leaves per tiller were higher in the summer when compared with the winter. Contrarily, stem elongation rate, phyllochron and leaf lifespan were lower in the summer when compared with the winter. During the summer, young tillers had higher leaf appearance and elongation rates when... |

| Combine harvesting is one of the most energy consuming field operations in arable farming. The power demand of combine harvester depends strongly on the mass flow through the machine, and one approach to reduce the energy consumption is thus increasing the stubble height in harvesting. In this study, the energy saving possibilities by increased stubble height and different straw management in cereal harvesting were examined. In addition to combine harvesting, the mulching of the tall stubble with a tractor powered rotary mower after the harvest was investigated. The results indicated an energy saving of 22%–24% in combine harvesting of spring wheat “Quarna” when the stubble height was increased from 13 cm to 35 cm, and 17% with 13 cm stubble when the... |
