In low-input systems, where most nutrients become available from soil organic matter (SOM) and residue turnover, the applicability of DSSAT (Decision Support System for Agrotechnology Transfer) crop simulation models is limited because (i) it recognizes only one type of SOM (i.e., humus) and rece...
A dynamic single-equation model for plant interaction is compared with the competition mechanism implicit in larger simulation models. When light is the limiting factor, both mechanisms can be written in the same mathematical form containing a ‘driving force’ and a restriction factor. In the sing...
Yield gap analysis is an important tool to estimate the potential crop production increases in a controlled environment. This analysis gives valuable insights into the biophysical requirements to meet food production goals. While yield gap analysis is well documented for cereals, there are signif...
Parasitic diseases of animals place a large constraint on livestock production worldwide. The parasite Theileria parva, and the disease East Coast fever it produces, are responsible for the deaths of thousands of cattle each year in central and eastern Africa. Disease control is one way in which ...
