Getting maximum benefits from cereals do not lie in reducing N-rate and its number of splits but lowering cost per unit cereal production through higher yields. Field experiments were conducted on maize (Zea mays L.) at the New Developmental research Farm of NWFP (Northwest Frontier Province)...

Farmers are interested in knowing whether applying inputs at variable rates across a field is economically viable. The answer depends on the crop, the input, their prices, the cost of variable rate technology (VRT) versus uninform rate technology (URT), and the spatial and yield response...

The effects of considering variable within-farm soil runoff and leaching potential on costs of reducing nitrogen losses … are analyzed for a Virginia dairy. Manure applications may cause nitrogen losses through runoff and leaching because of … factors such as uncertain nitrogen mineralization. Farmers can reduce nitrogen control costs by applying manure on soils with …

Unilateral abatement is sometimes advocated in order to set a good example that will make other countries follow. The aim of this paper is to investigate whether existence of correlated cost uncertainty provides an incentive for a country to undertake unilateral abatement. The theoretical model...
