The primary cause of seed biodeterioration has been identified as the ability of seed molds to generate many kinds of hydrolytic enzymes. The effects of six Alternaria species—A. alternata, A. citri, A. crassa, A. macrospora, A. dianthicola, and A. tenuissima on nutritional supplies such as ash content, carbohydrates, nitrogen, protein, and fat were investigated in relation to seed biodeterioration. The immediate effect on productivity and seed quality. These seeds are regarded as being of low quality both for the seed industry and for human consumption. Mycotoxin from fungi ruins the contents of the seeds. Taking into account that efforts were undertaken to investigate the effects of nutritional sources because of Alternaria species. For six months, the effects of Alternaria species were observed bimonthly on the following parameters: moisture, total fat, crude protein, nitrogen free extract, and ash levels. During the storage period, the seeds underwent deteriorative alterations due to the presence of Alternaria species.
