The timing of sowing varies depending on the season—spring, summer, or autumn. The exact time for planting is determined by several factors, including soil temperature, moisture levels, the growth characteristics of the forage plants, weed pressure, and the intended use of the pasture. It is ideal to sow when the soil has warmed up to the minimum temperature required for seed germination, the moisture is sufficient, weed competition is low, and there is minimal risk of pests or diseases. In arid regions, soil moisture becomes the primary concern, while in colder climates, the ability of the grasses to survive the winter plays a key role in determining the sowing schedule.
Larger seeds are generally sown more densely than smaller ones. Pastures that will be harvested multiple times require higher seeding rates compared to those that are only cut once. Seed broadcasting usually involves a higher rate than drilling, and drilling is more efficient than direct seeding. In early spring, when temperatures rise slowly, or in wetter areas, the seeding rate can be lower. However, in cold or dry regions, where germination might be delayed or hindered, the seeding rate should be increased, especially if seed quality or soil conditions are not optimal.
Seeding methods include broadcasting, drilling, fertilizer banding, and furrow sowing. Drilling involves placing seeds in evenly spaced rows and covering them with soil. In wet or irrigated areas, the spacing between rows is typically around 15 cm, while in drier conditions, a wider spacing of 30 cm is used. For pastures meant for harvesting, the row spacing often ranges from 45 to 100 cm. Broadcasting involves spreading seeds evenly over the soil surface and lightly covering them. In colder regions, seeds can be scattered directly onto the ground in winter without covering, allowing natural freezing and thawing to help incorporate the seeds into the soil.
Fertilizer banding involves applying nutrients directly under the seeds, typically at a depth of 4–6 cm below the seed placement. This method is particularly effective for phosphorus-based fertilizers. Furrow sowing is commonly used in arid or semi-arid regions with deeper topsoil. It involves creating furrows using machinery, animals, or manual labor, then placing seeds on the moist layer within the furrow. These furrows remain undisturbed until harvest or the end of the growing season. This technique is also beneficial in high-altitude or cold regions, as it helps improve the survival rate of forage during the winter months.
