Agronomic Yields of Alfalfa — Main Cropping System Experiment (MCSE)
Dry matter yields from machine harvests of the MCSE Alfalfa treatment (T6). Note some years have multiple harvests per year and some years are missing due to management as a 5- to 6-year rotation with winter wheat as a 1-year break crop
This datatable is part of the Agronomic Yields of Row Crops dataset.
This dataset contains the agronomic yields of row crop treatments of the Main Cropping System Experiment (MCSE) at the LTER Main Site and includes corn––soybean–winter wheat rotations (T1-T4), managed differently since 1989, and alfalfa (T6, 1994-2017) which was converted to switchgrass (T6) in 2019. Agronomic yields are measured during normal crop harvest using machine harvesters appropriate to each crop as detailed in the KBS Aglog.
