The work was carried out to evaluate the effect of nitrogen fertilization in the composition of the forage as grazed and on the tiller dynamics of Alexandergrass (Urochloa plantaginea (Link) Hitch) utilized by beef heifers ...

Controlled burning is often used to improve plant structure on rangelands adapted to fire. However, possible damage resulting from post-fire grazing to reappearing desirable plant species may be a serious issue hindering ...

Selection for maize (Zea mays L.) grain yield in high-yielding environments at high population densities has favored a compact phenotype tolerant to crowding stress, bearing a single, well-grained ear. However, by contributing ...

Bud viability after various defoliation frequency treatments was determined in the perennial bunchgrass Poa ligularis under arid field conditions from 2002 to 2005. Bud respiratory activity was examined on various stem ...

Effects of the timing and frequency of defoliation under different levels of soil water availability were evaluated on bud metabolic activity and subsequent outgrowth in the desirable (i.e., palatable) Stipa clarazii Ball. ...

Changes on plant morphogenic characteristics modify sward structure and, consequently, alter microclimate wherein plants grown. In this sense, dynamics of pasture tiller population is altered, characterizing the complex ...

Knowledge of the productive potential of the species, in response to nitrogen (N) fertilization, can reduce the risk of environmental contamination, since to minimize losses of N, this nutrient must be supplied in an amount ...
