Collaborative project: Sensor-based herbicide-free weed control in plowless peas and field beans. Coordination (herbfreiErbAB)
Project
Project code: 2815EPS006
Contract period: 16.06.2017
- 31.12.2020
Budget: 211,169 Euro
Purpose of research: Applied research
In three-year field trials (2017-2020) with four repetitions in randomized plots in conventionally and ecologically cultivated area at three soil types in Saxony are to be investigated how the cultivation of non-legum intercropping plants can reduce the germination and growth of weeds. In the following are peas and field beans cultivated in mulching and direct sowing system and its be investigated how the weed control with a roll harrow can be omitted or limited to partial areas. The intercropping-strow remains after the freezing as mulching material for the protection of the soil against erosion and for weed suppression on the surface. With the limitation of the mechanical weed control to the areas with weed, the associated light stimulus of the work of the tool, which promotes the new emergence of the weed, is to be largely restricted to areas which are necessary for the treatment of the areas with weed. Using a camera-based sensor, the degree of weed coverage is to be recorded and evaluated for a recommended application for a roll-harrow. In the last project year, the sensor signal is to be used as a control signal for segments of a roll-harrow. At the same time, a segment controller is developed for the implementation of the control signal. The overall objective of the project is to further develop cultivation methods for peas and field beans so that a plowless cultivation is safely possible both in organic farming and in conventional cultivation without herbicide use. The interim and final results of the project are presented on field days and a final event as well as publications. 2017-2020 Field trials to investigate the effect of non-legum intercropping plants on weeds and yield in plowless peas and field beans 2018 and 2019 Using a camera-based sensor, the degree of weed coverage is to be recorded and evaluated for a recommended application for a roll-harrow 2020 the sensor signal is to be used as a control signal for segments of a roll-harrow, testing the sensor-controlled roll-harrow (Segment) 2018-2020 a segment controller is developed for the implementation of the control signal The interim and final results of the project are presented on field days and a final event as well as publications
