Mathematical Models for Resource Management.

Punjab state (India) has highest per unit area basis productivity in the country for all major crops grown in the region. Intensive cropping system and high crop productivity proportionally consume high amounts of inputs like diesel, electricity, fertilizers, chemicals and water. It is logical to understand the spatial resource use pattern to select best management practices for every region. Mathematical models have been developed to estimate resource requirement under diverse crop production system. Point models applied on large region predict spatial resource use pattern. Models have also been developed to demonstrate spatial variability in economics of crop production and total energy use on large regions.
