| In this work several performance indicators such as the Annual Relative Irrigation Supply (ARIS) and the Irrigation Water Productivity (IWP), have been considered to evaluate the changes in the cotton irrigation management due to the decoupling of the European Union Subsidies. For this purpose, a modern irrigation scheme, the Genil–Cabra Irrigation Scheme (GCIS) located in Southern Spain, has been selected. The total irrigated area is 6,900 ha with wheat, olive and cotton as the main crops. The irrigation season 2004/05 was the period when the crop pattern and water management trend changed dramatically. From this year to the present the area cultivated with crops with high water requirements like cotton, sugar beet and maize has been reduced almost by... |

| The paper presents an approach to allocate joint costs to production branches based on maximum entropy. Using bookkeeping data from the Farm Accountancy Data Network (FADN) we derive full product costs. Accordingly, the suggested approach offers the opportunity of full product costs based on actual costing rather than normal costing. The approach is applied for arable crop in Switzerland providing full product costs on a hectare base. The resulting total costs are up to 20 percent higher than in literature. An important reason is labour, which shows for all analysed production branches higher costs than in the actual costing based literature. |
