One of the characteristics is they contain genetic material (DNA), which is a characteristic that all living things must have in order to be considered living.   And also wâ¦hen inside a host, they are able to reproduce, which all living things must be able to do. Hasmida Muhamad.
When milk prices are low, dairy producers begin to look for ways to reduce the direct input expenses of growing alfalfa. One option that growers have is to purchase lower cost alfalfa seed. Alfalfa seed of modern varieties can cost over $4.00 per pound, while older varieties can be purchased for $2.00 per pound or less.
To achieve seed stands of these densities, growers have been sowing 0.5 to 1.0 lb/acre (0.5 to 1.0 kg/ha). Considering alfalfa contains about 220,000 seeds per pound (485,000 seeds per kilogram) even these low seeding rates can be too high. However, even under the best managed conditions there is considerable seedling mortality before the stand produces its first crop.
