This report describes standardized data for “2.7-Rabi (winter) crops-all nodes-Long term trial (LT)-Choochbehar-West Bengal”. These data were standardized on 2024-05-21 by Mitchelle Njukuya with this R script. The original data have a not specified license. Because of the restrictions of this license, you need to run the script yourself to get the standardized data.
