| The apple variety 'Retina' is recommended for organic production in Denmark. Yet, there is no knowledge regarding the optimal rootstock for this variety. Better knowledge is also needed on production techniques, such as weed control, where different machinery for mechanical weeding is available. Therefore, we tested the combined effect of different rootstocks and weeding techniques including soil covering with straw. As organic growers discus the necessity of weed cleaning at all, the natural vegetation was used as control treatment in the trials. |

| 6 different soil treatments: Mechanical weeding to the middle of the alleyway, mechanical weeding using 3 different equipments Clemens, Humus and a dish harrow, Soil covering with wheat straw and natural vegetation were combined with 3 rootstocks: M9, J9 and M26 to find the best combination for the apple variety ‘Retina’. The trees were planted in the winter 1997/1998, only sprayed at primary RIMpro warnings and drip irrigated. The tree growth, nutrient content of the leaves in august, yield and fruit quality were determined. The rootstock J9 had the highest yield and the biggest amount marketable fruit. Mechanical cleaning to the middle of the alleyways, tree row weed control using Humus or soil covering with straw gave the highest yield and... |

| Samproduktion af fjerkræ og frugt er et emne, som er blevet diskuteret og prøvet i økologisk frugtdyrkning i Danmark. Fjerkræets skraben efter føde kan muligvis formindske populationen af skadedyr, som tilbringer en del af deres livscyklus i jorden. I økologisk forskning er meget få forsøg med kombineret vegetabilsk og animalsk produktion udført. Behovet for alternative metoder til at regulerer skadedyrspopulationerne meget efterspurgte, fordi økologisk æbleproduktion i Danmark har meget få økologiske sprøjtemidler til rådighed. Æblehvepsen (Hoplocampa testudinea) giver store udbyttetab i æbler. Æblehvepsene lægger æg under blomstring og larverne ødelægger de små frugter, der falder til jorden før modenhed. Laven overvintre og forpupper sig i jorden.... |

| In organic production in Denmark, no pesticides are allowed. The need for alternative pest control is therefore large. Apple sawfly (Hoplocampa testudinea) cause big crop losses in apples. Sawflies infest fruitlets and cause these to drop prematurely after which the pests pupate in the topsoil. Combined production of hens and fruit trees is a subject often discussed in organic fruit production in Denmark. The feeding poultry may reduce the population of pests, which stay in the soil as a part of their life circle. Yet, very little research has been carried out on this type of production system. |
