Animal and forage responses on lucerne (Medicago sativa L.) pastures under contrasting grazing managements in a temperate climate
(Wiley, 2020-06)
This study determined the impact of a change in grazing system on beef production from lucerne pastures in Argentina. One system (T500) used the traditional recommendation to commence grazing in spring when lucerne was ...
Increased hydraulic constraints in Eucalyptus plantations fertilized with potassium
(2021-01-01)
Fertilization is commonly used to increase growth in forest plantations, but it may also affect tree water relations and responses to drought. Here, we measured changes in biomass, transpiration, sapwood-to-leaf area ratio ...
Severe phosphorus stress affects sunflower and maize but not soybean root to shoot allometry.
(Amer Soc Agronomy, 2013-09)
The predictions of two models on biomass allocation were compared on P-stressed and non-stressed crop plants. Allometric coefficients were calculated from paired measurements of root and shoot biomass obtained from field ...

Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(Elsevier Science, 2016-02)
It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ...
