2 Codron Farm Case Melis Gn is a medium-sized farmer on his 500 decares of land in the north of Antalya. She has been in this market as a Codron Farn by expanding farm since 2018. It plans to plant wheat, barley, oats and rye in the coming season. The table below shows the estimated values for these products' yields, labor requirements, pre-harvest expenditures, water requirements other than rain, and sales prices. Estimated Revenue (kg/decares) Labor Requirement (hour/decares) Pre-harvest Expenditures (TL/decares) water requirements (ton/decares) Sales Price (TL/decares) Wheat Barley Oats Rye 525 750 150 600 1 1,25 0,75 2,5 18 28 11 22 5 15 2,5 10 0.18 0.39 0,215 0.155 Codron Form expect to produce at least 80 tons of wheat and 80 tons of barley. The demand of oat in market has been decreasing year by yner. Therefore, the maximum tons of ont to produce is 50 tons. The company is a budget of 16 thousand TL to spend on products throughout the year and will be able to work 9 hours a day during the 200-dny product development period. It will be able to provide a total of 5000 tons of water throughout the your from the irrigation cann. . a) Write decision variables of the case and explain them in detail.
