The improvement and application of pest and disease models to analyse and predict yield losses including those due to climate change is still a challenge for the scientific community. Applied modelling of crop diseases and pests has mostly targeted the development of support capabilities to schedule scouting or pesticide applications. There is a need for research to both broaden the scope and e...

The uncertainty of water quality predictions caused by uncertainty in the inputs related to emissions of diffuse pollution is analysed. An uncertainty analysis of the effects of diffuse pollution is essential to compare the cost and benefits of measures to lower those emissions. We focus on diffuse nitrate pollution due to fertiliser use. Using an efficient Monte Carlo method and Latin Hypercub...

The paper elaborates upon a hybrid approach of data mining and statistical methods, being investigated to modelling climate effects i.e., arising from year-to-year variability in weather conditions, on grape crop of three different varieties cultivated in northern New Zealand. Recent research using iterative χ method based approach to modelling climate effects on “high” and “low’ yearly yield (...

The level of nitrogen leaching from organic compared to conventional farming was evaluated by using a systems modelling approach. Two different methods were used for estimating and evaluating nitrate leaching. A simple function was used in which nitrate leaching is dependent on percolation, soil clay content, average nitrogen input and crop sequence. A nitrogen balance model was used to estimat...

Aim Crop wild relatives (CWR) are an essential source of genetic material for the improvement certain traits in related crop species. Despite their importance, increasing public, scientific and political support, large gaps exist amount collected conserved many CWR. Here, we construct a dataset on distribution banana species (Musa spp.) assess risk conservation status. We deal with following qu...

Using the GECROS model, we simulated effect of improvements in photosynthesis a range growth parameters, including yield, and on εc (the conversion efficiency absorbed solar energy to chemical biomass) εi interception or absorption by canopy) parameters Monteith crop equation, for wheat potato (which use C3 photosynthesis) maize uses C4 photosynthesis). In case crops, were via 20% increases Vcm...
