Weed control in silage maize production with preventive and systematic measures within the design of crop rotation and cultivation (UNSIFRAN)

Project


Project code: 2815OE093
Contract period: 01.09.2019 - 31.03.2023
Budget: 95,172 Euro
Purpose of research: Applied research
Keywords: crop production, pea, production, feed crop production, maize, weed, catch crop, organic farming

Weed control is one of the most important challenge in silage maize production in organic farming systems. This challenge should be overcome by a preventive approach regarding the design of crop rotation and cultivation system. Therefore, the systematic investigation of an element of crop rotations is planned, which contains the cultivation of winter peas in pure stand or in mixture with triticale and of winter vetches in pure stand or in mixture with rye as first or pre crop, followed by silage maize as second crop. This will be cultivated with reduced or without tillage and with common (75 cm) and reduced row distance of 37,5 cm. The joint project will be conducted by the University of Kassel, Dept. Grassland science and renewable plant resources (coordination), by the Thünen-Institute for organic farming and by the Bavarian State Research Centre for Agriculture, Institute for organic farming, soil culture and resource protection. Field trials will be conducted at three sites and following aspects will be investigated: 1) Potential of pre/first crops for preventive weed reduction in following silage maize due to their biomass development. 2)    Effects of different treatments of pre/first crops: Whole crop harvest of mixtures or mechanical destruction of mixtures and of crops in pure stand by treating with a roll chopper. Investigating the effects on weed dynamics in following silage maize. 3)    Investigating the effects of reduced tillage (after harvest of mixtures) or of no tillage (after destruction of pre/fist crops) regarding weed dynamics in following silage maize. 4)    Effect of reduced row distance (37,5 cm) in silage maize regarding weed dynamics in silage maize. Dissemination: field visiting; demonstration project on 'Öko-Feldtage” 2021; demonstration project at agricultural farms in 2022; presentations and talks on scientific and practice-oriented conferences; publications in scientific and practice-oriented journals
