The use of winter peas becomes more and more common in organic agriculture. In field trials, winter pea-triticale intercrops were compared with spring peas concerning their yield performance. The differences in gross margins were calculated by using data from origin farms. Savings in seed costs (-136 €/ha) and machine costs (-13 €/ha) could be gained by replacing spring pea sole crops with winter pea-triticale intercrops. Additionally, there were yield increases of 33 % for intercropped winter peas, which resulted in an extra benefit of 378 €/ha. Aside from that, the intercropped triticale provides an extra income. |

Rotklee, Luzerne und Weißklee stellen vor allem im Gemenge mit Gräsern in zahlreichen ökologisch wirtschaftenden Betrieben die Basis der Winterfutterversorgung dar. Ertragsleistung und Futterqualität sind durch pflanzenbauliche Steuergrößen in weiten Bereichen beeinflussbar. Zu Vergleichen zwischen Rotklee, Luzerne und Weißklee hinsichtlich ihres Leistungspotentials liegen unter mitteleuropäischen Klimaverhältnissen nur wenige Untersuchungen vor. Im Rahmen eines dreijährigen Feldversuches der Einfluss der Faktoren Leguminosenart (Prüfglieder: Rotklee, Luzerne, Weißklee) und des Leguminosen/ Gras-Saatmischungsverhältnises (Prüfglieder: Leguminosenreinsaat, Leguminosen-Gras-Gemenge, Grasreinsaat) auf den TM-Ertrag, den Leguminosenanteil sowie die... |

Despite more than 30 years of research and practical experience the interest in shallow tillage and especially direct drilling has remained low in Scandinavia. Excessive compaction of the topsoil layer is one of the major problems encountered when adapting shallow tillage and direct drilling in particular. The purpose of this study was to evaluate temporal and spatial effects of two different direct drilling techniques on bulk density and penetration resistance in the near seed environment. A sandy loam growing small grain cereals was followed during the first 3 years after conversion from conventional tillage to direct drilling to reveal short-term changes in soil structure. A field experiment with four blocks was conducted in 1999–2001 where a... |

It appears that the growth of barley seedlings during spring is restricted by moderate internal deficiency of phosphorus (P) and potassium (K) in most cases. This agrees with the well-known increases of growth and grain yields if P and K fertilizer placement is used in spring barley growing. It is also evident from our earlier work that barley cultivars may differ in the P acquisition from soil (Gahoonia and Nielsen, 2004; Gahoonia and Nielsen, 2003). The existence of cereal varieties differing in the efficiency in P uptake from soil suggests that more nutrient efficient varieties can be identified among the existing varieties. The aim of this work was to study differences between selected barley cultivars in their soil-P and soil-K acquisition to... |

Ligesom sidste år blev det en utrolig nem og tidlig høst. På Jyndevad blev der sået den 25 marts og høstet vårsæd den 29 juli. Forsøget på Foulum blev høstet den 12 august, så selv her er det gået hurtigt i år. Vi har endnu ikke de endelige udbytter fra sædskifteforsøget, men vi har en ide om hvordan det er gået. Der er i øvrigt mere at læse om forsøget på web-loggen på internettet under http://www.foejo.dk. |
