The quadratic programming model presented above was used to identify the
risk aversion levels of the farmers. The risk aversion level of the farmer was
taken to be that value of the parameterized coefficient (R) which minimized
the difference between the model results and the actual crop mix followed by
the farmers. The difference was measured in terms of the total absolute
deviation in acreage of each of the crops and in terms of the summed total
absolute deviation of all crops [10, 19]. Relevant results of the impacts of
agroforestry systems on the cropping patterns, input use, net farm income,
and nutrient availability of five major nutrients are discussed for both
irrigated and dry land farming systems.
