WIS128 CORN SCIENCE 02/23/1990 03:35 PM D1 305 Lines Agriculture Science/Production Management Corn Science (10-40 days) This unit deals with various aspects of the corn science industry. Topics include corn uses and production areas, corn plant development, management decisions, seed corn production, safety guidelines, and career opportunities. Objectives To acquaint students with employment information and career opportunities in the corn science industry To introduce students to the different types, uses, and production areas of corn To develop student appreciation for the economic and social significance of corn as an agricultural crop To develop student understanding of the development of corn from seed to maturity To develop student understanding of the practices and principles involved in seed corn production and their significance to agriculture To enable students to make and implement more effective management decisions concerning the planting, cultivation, harvesting, storage, and marketing of corn To develop student appreciation for the need to adhere to safety guidelines in all aspects of agricultural production Competencies At the conclusion of this unit, students will be able to explain current employment information such as job descriptions, job availability, personal and educational requirements, working conditions, opportunity for advancement, and other factors relative to potential employment in the corn industry and relate it to their personal needs and aspirations; identify the different types of corn; locate corn growing areas; explain different methods of hybrid seed corn production; determine proper herbicides, insecticides, and fungicides for corn production; recognize the different methods of corn harvesting and storage; explain the different marketing techniques for corn; exercise safety measures relevant to corn production and chemical applications; conduct a plant population count; and identify corn growth stages and kernel development.
