The percentage gain depends upon a number of variable factors such as initial and final moisture content of the grain, prevailing temperature and Relative Humidity (RH) conditions, storage conditions of food grains, etc. These conditions vary from year to year, region to region and State to Stage. IGMRI, Hapur and its field stations have carried out a number of scientific studies under field conditions in FCI/ CWC godowns to ascertain the percentage gain in wheat due to change in moisture. Since these conditions vary from year to year, region to region, no definite formula for fixing the gain in wheat could be worked out by the IGMRI. Although, some more studies are going on in IGMRI in this regard, it is not certain whether these would lead to some concrete conclusion about the exact quantum of gain in
