| From June 2005 till June 2007 different soil preparation techniques like chiselling and advance sowing of medicinal plants and green manuring were proofed for their influence on reducing plant losses of strawberries caused by root diseases like Phytophthora species and Verticillium dahliae. The variants were combined with potted plants and Frigos. The experiment took place on an organic fruit farm near Stuttgart, Germany, with the strawberry variety ´Elsanta´. Focused on root diseases, habit and yield chiselling combined with Frigos and green manuring combined with potted plants showed the best results. Generally the marketable yield was often below yields from conventional cultivation. This project is granted by Bundesprogramm Ökologischer Landbau (BÖL,... |

| This trial took place in an organic fruit growing farm located near Lake Constance with the variety ‘Elstar’ planted in 1995. In 2004 and 2005 one variant (control) was pruned normally during the winter, the other variant was pruned more intensively to reduce the amount of flower buds. In 2004 at both variants the number of apples was reduced to 165 apples/tree at the end of May. Time for thinning by hand was cut down significantly in the intensively pruned variant. In addition at harvest the number of apples with bigger diameters, especially 75-80 mm, increased. Moreover the number of flower buds for the next season rose by 20 %. Therefore in 2005 the yield per tree at the intensively pruned variant increased about 15 %, but also the working hours... |

| At the LVWO Weinsberg different agents were tested, in 2004 with the apple variety ‘Gala’ and in 2005 with the variety ‘Elstar’, both organically grown. In addition to the thinning effect its influence on yield, fruit quality (size, colour, russetting) and return bloom were investigated. An alternative to lime sulphur at the variety ‘Gala’ might be sunflower oil (thinning effect 42-62 %), but the number of blossom clusters in 2005 was up to 60 % lower than in the lime sulphur plots. In 2005 the variety ‘Elstar’ treated with fish oils also showed good thinning effects (31-42 %), but the percentage of flower buds for 2006 hasn’t been evaluated yet. However, in both years lime sulphur showed good results, too. The research project was financed by the... |

| Im Forschungsprojekt 03OE088 wurden verschiedene Bausteine zur Regulierung der Behangsdichte im ökologischen Obstbau bei Apfel und Birne an den Standorten Ahrweiler, Jork und Weinsberg untersucht. Es wurden Blattdünger zur Förderung des Ertrages bei Apfel und Birne geprüft und Versuche zum zusätzlichen Schnitt und zur Blütenausdünnung durchgeführt und deren Effekt auf den Handausdünnungsaufwand festgehalten. Der höchste Ertrag mit 11,58 kg pro Baum und Jahr (Mittelwert 2004-2006) wurde am Standort Ahrweiler (Sorte ’Elstar’) bei Aminosol PS festgestellt. Wuxal Ascofol erzielte mit 11,71 kg pro Baum das zweitbeste Ergebnis vor der Kontrolle (10,96 kg/Baum). Bei der Birnensorte ’Conference’ lag bei der Summe des Ertrages (Gesamtertrag und vermarktungsfähiger... |
