Farmer objectives, constraints
Input-output relations of current and innovative (EP’s) agricultural activities, e.g.:• Input levels (cv’s, fertilizers, tillage, etc.), efficiencies• Productivity and composition, use of products• Post-harvest losses and processes• Labor requirements and availability• Costs and prices• Etc.
