NO SUCCESS WITHOUT GOOD SEED
It is a time-worn but no less true saying that good seed is essential to good agriculture. No matter how well the farmer prepares his land, no matter how much time, labor and money he spends on it, if much or all of his seed fails to grow, he will either have a poor crop or be obliged to reseed, thus losing time and labor. Many causes may contribute to prevent a good stand, but if he can eliminate any one of these, he is by so much the gainer. Poor seed is a primary and great cause of a poor stand.
