This refers to grains that are poorly fertilized. Some grains have only husks and no fully developed grains. This occurs when fertilization is prevented by low temperatures, rainfall, or excessive dryness during flowering, or when there is a lack of nutrients after fertilization, preventing the transfer of nutrients.
