| Due to higher prices in the organic compared to the certified integrated apple production, fruit growers are more and more interested in the conversion from integrated to organic production. With the return-risk profile based on Mouron (2001a) it is possible to identify the return and risks with economic indicators from the full cost account and the cash flow statement. Therefore, the return-risk profile serves as a basis for decision- making for producers concerning an evaluation to convert to organic. The return of the organic apple production is about 7% better than the certified integrated production. The risk of the organic production is higher because of the difficulty of braeking the alternanz and loss due to insect pests and diseases. The... |

| With economic indicators from the full cost account and the cash flow statement it is possible to identify the return-risk profile for the organic and the integrated apple production in Switzerland. The full cost account and the cash-flow time line are composed with the managerial-economical software-tool Arbokost. Due to higher (more than 100%) prices in the organic production, growing organic satisfies more return-oriented producers than growing certified integrated. However, the higher return in the organic production is bound to a higher risk. With the certified integrated production (IFP), return and risk are lower. ‘Arbokost’ is an economic farm management software tool for fruit growers. Per orchard it reflects a full cost account, the cash flows... |

| Shading with nets of 2 m and 3 m width respectively, which reduce the photosynthetic active radiation by 74%, lead to successful fruit thinning of apple trees. In field trials, three days of shading reduced fruits per 100 flower clusters to a satisfactory extent for Golden Delicious (if shading occurred after 19, 26 and 33 days after full bloom (DAFB)) and Topaz (if shading occurred after 19 and 26 DAFB). For Elstar, seven days shading at 25 DAFB resulted in a good thinning effect. However, practicability of the method in commercial orchards has to be improved. |
