REX ANPP — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Annual crop total biomass and grain yields from the Rain Exclusion eXperiment (REX), from the continuous no-till (T2) treatment within the Main Cropping System Experiment (MCSE). Crop biomass was sampled within a 1m2 quadrat at harvest time after being exposed to three different rainfall regimes (Drought, Variable Rainfall, and Irrigated Control) over the course of the growing season. Total biomass includes stover mass and grain yields.
This datatable is part of the Rainout Experiment dataset.
