Although only warm germ test results are printed on the seed bag, a grower can easily retrieve cool germ results by recording the lot number and asking the local seed company representative for the cool germ test results for that lot number. Observing cool germ test results is also a good standard practice that is commonly under-utilized. Smaller-seeded varieties can also be our highest-yielding varieties in some years, however extra care may sometimes be necessary to ensure vigorous seedling growth and acceptable stand establishment, including upwards adjustments in seeding rates, delaying planting until conditions are optimal, use of seed treatments and/or in-furrow insecticides, hill-dropping, etc. As seen from variety trial results, yield potential appears to be independent from seed size, as long as acceptable stands are established….in other words, high yields can be achieved from both large and small-seeded varieties as long as plant stands are adequate or optimal. It is important to note however, that variety decisions should be based on factors such as lint yield and yield stability, fiber quality, technology packages etc., with seed size considered mostly in regard to how that seed should be managed at planting. Lastly, improvements in vigor can be achieved through adequate protection from early season pests such as thrips and occasionally the use of starter fertilizers (in a 2×2 placement).Īs mentioned above, seed size can be one predictor of vigor as larger-seeded varieties tend to be more vigorous, which will be discussed later in this article. Soil temperatures at planting and soon thereafter can also greatly influence seedling vigor. Naturally, seed size and performance in warm and cool germination tests can be indicators of how vigorous seedlings might be. Seedling vigor (seedling size, health, and growth rate) is the product of several factors related to genetics and environmental influences, and can also be manipulated through management.
