72 BIOTECHNOLOGY FOR UTAH AGRICULTURE: HARNESSING THE NEW TECHNOLOGY An overview of the biotechnology's potential contributions and a synopsis of some of the related research supported by the Experiment Station.

80 UNDERSTANDING THE CAPRICIOUS GREAT SALT LAKE G. E. Bingham, E. A. Richardson, and G. L. Ashcroft Researchers have used several analytical techniques and a variety of data in their attempts to discover why water levels change in the Great Salt Lake. They have discovered important precipitation patterns and apparently identified the additional information needed to help them predict changes in lake level.

86 DETERMINING AGRICULTURE'S CONTRIBUTION TO UTAH'S ECONOMY D. L. Snyder, J. E. Keith, J. C. Andersen, and C. Diamond Economists use an input-output model to determine the economic impact of agriculture. Results indicate that agricultural development has a substantial impact on income and employment.

90 HYBRID CROPS THAT ‘CLONE' THEMSELVES J. G. Carman, C. F. Crane, and J. E. Hughes Researchers are attempting to transfer apomixis, a form of asexual reproduction in which seeds are identical to the parent plant, to wheat. The resulting hybrids would dramatically increase yields and cut farmers' seed bills.

95 AGRICULTURAL DEVELOPMENT OR EXPANSION IN UTAH D. L. Snyder and T. F. Glover There appear to be substantial opportunities to increase revenue from specialty crops if producers hone their marketing skills.

100 VACANT FEDERAL GRAZING ALLOTMENTS IN THE WEST E. B. Godfrey, D. B. Nielsen, and D. D. Lytle Some grazing lands administered by the Forest Service and Bureau of Land Management are in high demand while others aren't. Although relatively few grazing allotments appear to be vacant, there are indications that more may become vacant in the future, particularly if costs of using these lands increase.

103 APPLICATION OF HYBRIDOMA TECHNOLOGY TO AVIAN COCCIDIOSIS M. A. Laxer, M. C. Healey, and N. N. Youssef Biotechnology may lead to the development of new vaccines against avian coccidiosis. Results might eventually let researchers genetically engineer bacteria to produce antibodies in the body

106 HOUSEHOLD APPLIANCES AND HOUSEWORK: MORE EQUIPMENT MAY NOT MEAN LESS WORK Jane McCullough Those who buy household appliances to reduce work loads may be disappointed. Results of a recent survey indicate that appliances often don't significantly reduce the amount of time spent on household chores, and that, except for maintaining the home and yard, most husbands spend little time on household tasks.
