ABSTRACT

The farmer’s entire crop depends on the quality of the seed he plants. If the seed does not germinate, he will not get a stand. If the seed is of mixed varieties or crops, the value of his crop will be less, and yields will be lowered. If seed of a disease-susceptible variety is mixed with the seed he plants, yields will be lower, and the diseased plants may contaminate his entire production. If his seed contains weed seed, the farmer establishes troublesome weeds in his fields, and thus increases weed control costs and weed competition to his crop plants. If he plants seed containing inert matter, he buys and plants that much material of no more value than a mulch.
