Synopsis Sorghum is mostly cultivated in Kharif and rabi seasons in India. Maharashtra ranks first in the production of sorghum grain crop. The production of grain sorghum is higher per hectare in kharif season than the rabi season, because during kharif season there is occurrence of rain. So, the water availability is more as well as the climate is warm and humid which is good for sorghum growth. Similarly agricultural universities also developed several hybrid genotypes, which yield high-level grain production.

During last decade the kharif season sorghum is often vulnerable and the grains gets deteriorated due to mould attack becoming red or black grains because of the occurrence of rains during kharif season. During rainy season water accumulation occur in the glumes, which dissolve the pigmented material and spread over all grains. Moist condition supplements various types of fungus growth as well in the grains. Therefore, such type of sorghum grains become unfit for human consumption. This results into the loss of income from sorghum to the farmers.
