A characteristics model, which assumes goods generate a common set of attributes but no unique attribute, is described. The model yielded two equations which were estimated. One was a set of hedonic price equations in which the price paid for each food purchased was a function of imputed attribute prices. This set of equations was estimated at the household level. Nutrient demand equations were estimated across households. Imputed prices, income, and household characteristics including location, size, education, age distribution, and race affected nutrient demand levels.

Faculty are regularly appraising the mathematics and science requirements associated with particular majors. As curricular revisions occur, determining math and science requirements in the agricultural curricula need to be reassessed within the context of emerging technology, competing curricular needs, and career goals. The purpose of this paper was to determine the amount of required mathematics and science associated with production-oriented agronomy majors using information supplied by cooperating institutions. A secondary purpose was to determine if curricular requirements vary between land-grant and nonland-grant institutions. Reported mathematics requirements largely centered around college algebra and statistics. Science requirements included inorganic chemistry, one semester of organic chemistry, and biology, generally including plant physiology and genetics. Supporting courses in computer science and courses such as soil fertility augmented the science experience. Land-grant institutions generally require a more rigorous mathematics and science regimen, while nonland-grant institutions generally require a stronger agribusiness orientation.A GRONOMY CURRICULA are frequently structured along ./"\strict discipline lines with options arranged in (i) production, (ii) science, or (iii) agribusiness. Based on catalog descriptions, the science option is usually arranged around the natural and physical sciences, mathematics and computer science, with 20 to 25 semester hours in traditional agricultural courses. Students entering this option generally M. Aide,
