2-years rotation, an alternative to maize monocropping in Bearn (France)
Creators
Description
Problem
In Bearn, maize is well adapted to the pedoclimatic context, with no loss of yield potential when grown as a monocrop. But, regulatory pressure and price volatility risks, as well as increasing attacks from bio-aggressors, threaten maize monocropping. It is essential to experiment with alternative cropping systems combining respect for the environment, efficient management of bio-aggressors, productivity and profitability.
Solution
As an alternative to maize monocropping, a 2-years rotation has been implemented (Figure 1). It consists of a sequence of 4 crops in 2 years: maize, cover crop (oats & mustard), soybean and oats as an energy catch crop (ECC). Thanks to the introduction of legumes and cover crops, which enable crop diversification whilst qualifying for coupled aids, this innovative system has proved to enhance agronomic, environmental and economic performances.
