The North Carolina Cooperative Extension recommends that everyone who depends on crops for a living, as well as homeowners establishing lawns and gardens, consider seed selection as the first step in production. AG-448. Seed offered for sale must meet certain minimum standards. Private seed companies that develop new varieties normally maintain their own breeder and foundation seed programs. Seed of new varieties must be made available to farmers for use in their farming programs, and pure seed stocks of older but satisfactory varieties must be maintained. As seeds age, both germination and vigor decline, slowly at first and then more rapidly as the end of the seed’s useful life is reached. Seed is an agricultural input on which the foundation of a healthy and quali Germination is reported as the percentage of seed producing normal seedlings. The law also requires the individual or company owning the seed to maintain a current germination test date. County Extension agents and seed dealers are often called upon by farmers who have crop stand problems. Time: 11am- 12pm | Venue: Twitter | date | 2moro Wed, Others are particularly well suited to lubrication. commitment to diversity. The female part is the pistil, and the male part is the stamen. They range in size from the micro-miniature orchid seed, as small as a particle of dust, to the gargantuan double coconut seed, over 1 foot long and weighing many pounds. For example, the cold test for corn, the cool test for cotton, and the accelerated aging test for soybeans have proven to be reliable vigor tests that correlate very well with storage life and field emergence. Nonflammable fumigants are sometimes used for controlling insects in stored seeds. For example, peanut seed has been stored in the laboratory under special refrigerated conditions for as long as 10 years, and in normal laboratory storage, it survives for two to three years. The following definitions will help in understanding seed germination and seedling emergence: Various seed characteristics result in different germination and seedling emergence patterns. Seeds of the jojoba (a little known but very useful desert plant from the American Southwest) contain an oil that has lubricating properties as good as those of the finest sperm whale oil. For example, gemination test results on two peanut seed lots were 99 percent (lot A) and 98 percent (lot B). It is important that seed be harvested as soon as the moisture content decreases to a safe level (see Table 2). In cross pollination, pollen is moved long distances. Seed storage conditions, which can also greatly affect deterioration rates, is discussed in more detail in a later section. (Initiators of Y-Farm Campaign) Topic: Y-Farm Campaign: Opportunities for active youth participation in Agriculture. The North Carolina Crop Improvement Association (NCCIA) is legally responsible for seed certification in North Carolina and is the official seed certifying agency. The initial price of bargain seed may appear low, but it frequently becomes very costly by harvest time. The Importance of Using High Quality Seeds in Agriculture Systems Sabry G Elias* Oregon State University, USA Submission: March 15,2018; Published: April 25, 2018 *Corresponding author: Sabry G Elias, Oregon State University, USA, Email: Sabry Agri Res & Tech: Open Access J 15(4): ARTOAJ.MS.ID.555961 (2018) 00100 Opinion Genetic purity, or trueness to variety, is established and maintained by special purification and seed increase programs, by field and seed inspections, and by pedigreed records. These practices are usually legal, but whenever seed is offered for sale, state and federal laws come into play. A seed dealer should have a current copy of the North Carolina Seed Law and a copy of Title 2, Subchapter 48C (“Seeds”) of the North Carolina Administrative Code. However, from the seed technological point of view seed may be sexually produced matured ovule consisting of an intact embryo, endosperm and or cotyledon with protective covering (seed coat). Seedsman or Vendor: The name and address of the person or company labeling the seed are given on the seed label. A useful guide for farmers and retail seed dealers for determining the best seed to buy is the “pure live seed” rating. For example, the equilibrium moisture content of corn at 77°F and 45 percent relative humidity is 10 percent; whereas, at 77°F and 90 percent relative humidity, it is 19 percent. Seed may be defined as “Structurally a true seed is a fertilized matured ovule, consisting of an embryonic plant, a store of food and a protective seed coat, a store of food consists of cotyledons and endosperm” The AOSA has also set standards and procedures for the use of the tetrazolium test as an estimate of viability and germination. In the case of proteins, seeds may not have the ideal composition in terms of human nutritional needs. The importance of Seed certification in agriculture are given below: i) Seed certification maintains the availability of high quality seeds and propagating of different kinds and varieties to the farmers through certification. Origin: This label entry identifies the state or country in which the seed was grown. However, several “hopper box” treatments are designed for easy on-farm use. Always read pesticide labels carefully, and follow all directions. An example of an acceptable label format is shown in Figure 11. Certified- 1 must meet higher standards. In some crops, conditioning includes the addition of chemical seed treatment. Title V protection is enforced by the regulatory section of the NCDA&CS and the USDA Seed Branch. Supplies of breeder seed are usually maintained by the originator of the variety. Thus seed is the most vital and crucial input for crop production, one of the ways to increase the productivity without adding appreciably to the extent of land now under cultivation by planting quality seed. IYA’s SEED CATALOGUE: Restricted noxious weed seeds are permitted in crop seed, but the number of weed seed permitted per pound of crop seed is limited. Indians. The internal conditions of seed, such as soundness and vigor, as well as the environment, affect the rate of germination. Thus, a single off-type plant in a seed field can pollinate flowers on hundreds of other plants. Depth settings are especially critical with multiple-row planting equipment. For example, seed with 98 percent purity and 80 percent germination rate has a pure live seed rating of: The comparative value of different seed lots can be determined by dividing the pure live seed percentage into the cost per pound. Farmers should be aware that the sale of uncertified seed of any protected variety by kind name may still be a violation of the owner’s civil rights, and the owner could bring civil suit against the seller. The seed law may be thought of as a “truth in labeling” law. Germination and other soundness characteristics may vary from season to season, In many crops, seed dealers and farmers have to accept the germination and soundness quality available. Most seed testing laboratories follow these rules. Seed quality plays an important role in the production of agronomic and horticultural crops. “Brown-bag” or “bootleg” seed is often of inferior quality. Choose seed that is high in germination (80 percent or more). For seeds used in farming and landscaping, the primary dispersal mechanism is the planter. Certain weeds are classified as noxious and are prohibited or restricted in seed offered for sale. Its genetic purity and high quality make certified seed the standard of excellence by which all seeds are judged. N.C. Chemically treated seed is also required by law to be dyed a bright color. Technology has modernized much of farming's day-to-day operations, but without a steady supply of high-quality seed, yields and crop quality would be greatly decreased. Talking about seeds, please could you help me give the various varieties of Sesame seeds and how to clearly identify them. The results show the actual cost per pound of pure live seed. If treated seeds are not planted, they should be disposed of as hazardous waste. Seed produced from foundation seed is identified as registered, provided that it meets published standards of quality. Advances have been made in vigor testing for many of the agronomically important crops. Corn seedlings with (a) normal seedling structures (that is, healthy shoot and root), (b) abnormal root structure, and (c) abnormal shoot structure.
