Vegetable production is without doubt the most diverse and demanding branch of Swiss Agriculture. Although neither crop husbandry nor the structures of cropping and farming systems differ significantly from that of other agricultural production areas, the crop diversity and the specific market requirements demand outstanding know-how and high organisational and economic capabilities from the producers. In no other agricultural branch is the time frame for strategic, tactical and operational decisions shorter than in vegetable production. Within this context, crop husbandry, such as sowing and planting technique, soil cultivation, crop maintenance, weed management and fertilisation are of key importance. Reducing costs, as one of the most important economic objectives, is a question of careful long term planning of the cropping- and farming system. Innovative approaches and flexibility are required in crop husbandry to avoid problems before they occur, as solving them later might be much more expensive. Increasing demands of the market and the requirement of sustainable resource utilisation will, in the medium term like in other countries, lead to greater specialisation among Swiss vegetable producers. As a result, the significance of an efficient and professional independent research and counselling service is more important than ever.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.
With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
