Seeding
Implements used in SeedingSeeders and planters used for field crops vary in size from one -row horse-drawn planters to multiple-row tractor-drawn implements.
Grain DRILLS: Combination grain and fertilizer drills are often used. The single -disk furrow opener is best for penetrating a hard seedbed or cutting through trash. Double-disk and shoe openers are best for mellow seedbeds that are firm bellow. The hoe-type opener is best in loose soil or where soil blowing is likely to occur. The hoe drill turns up clods and trash and does not pulverize the soil to any extent. The surface drill is used under humid conditions, while the furrow drill is widely used for winter wheat, particularly in the Great Plains under dryland condition.
Time of Seeding
The time to seeding or plant various field crops is governed not only by the environmental requirements for the crop, but also by the necessity of evading the ravages of diseases and insect pest.
If the conditions of the lands and of the weather will allow it, the sooner we sow, the better it will grow, and the more increase we shall have.

With many crops, it is a safe practice to seed at heavier than normal rates when seeding has been delayed materially beyond the optimum time determined for the region.
Rate of Seeding
The objective in spacing crop plants is to obtain the maximum yield on a unit area without sacrifice of quality. The rate of seeding is governed by the ultimate stand desired. Most crops are seeded at lighter rates under dryland than under humid or irrigated condition. Small short season varieties of corn require thicker planting than long -season varieties. Corn is generally planted in row 3 to 4 feet apart, because it has been determined in many experiments that rows more widely spaced resulted in lower yields, even under most dryland conditions. Under semiarid conditions in western Nebraska the highest yields were obtained when single plants were spaced 24 inches apart in the row.

Depth of Seeding
Seeds will emerge from greater depths in sandy soil than in clay soil, and in warm soil than in cold soil. It is customary to plant deep in dry soil in order to place the seeds in contact with moisture. Peas will emerge from a greater depth than will beans when the seeds are the same size, because the bean seedling must push the cotyledons up above the soil surface, whereas the pea cotyledons remain where planted.

That is some explanation of articles on seeding, hopefully we can add to the knowledge of the reader
