Product Description

Certified Organic Mara Organic Mara Perennial Ryegrass from Barenbrug Seeds and Byron Seeds is the standard for winter-hardy Organic Mara Perennial Ryegrass. Mara is a very high yielding and extremely grazing tolerant, persistent variety. It performs well from the transition zone with its hot, dry summers to upper Midwest with its extremely harsh winters. Mara is a component of BG-24T and BG-34 and is distributed by Byron Seeds.

When planting with a drill, the ideal seeding depth is ¼ inch or less. Do not exceed ½ inch seeding depth. Results from a Utah study indicate that broadcast seeding followed.

A firm, weed-free seedbed gives the best results. Spring seedings should occur in March to early May. Organic Mara Perennial Ryegrass may also be seeded in mid-August to early September under irrigated conditions. Timing for fall seedings should ensure that at least 6 weeks are allowed for establishment prior to killing frosts. Seeding rates will vary with local conditions and purpose of planting. Generally, a rate of 15 pounds per acre is used if Organic Mara Perennial Ryegrass is seeded alone. Double this rate if seed is broadcast planted. Organic Mara Perennial Ryegrass is also recommended for grass-legume mixtures, but due to a strong animal preference toward Organic Mara Perennial Ryegrass over other pasture grasses, it should not be planted with other grasses for grazing. Reduce the full rate to the percentage of mixture desired when planting with legumes. Because Organic Mara Perennial Ryegrass has very strong seedling vigor, it should be planted at 7 to 8 pounds per acre in alternate row plantings with alfalfa and other legumes. When planting in the same row, do not exceed 4 pounds per acre of Organic Mara Perennial Ryegrass in the seed mixture with alfalfa and other legumes.


Organic Mara Perennial Ryegrass is generally cut for hay when seed is in the soft-dough stage. Organic Mara Perennial Ryegrass responds well to good management, such as intensive rotational grazing and fertilizer applications. Organic Mara Perennial Ryegrass performs best when used in intensively managed pasture. It requires very accurate irrigation water management and fertilizer management. If either irrigation or fertilility requirements are not met, it will immediately cease growth.

Organic Mara Perennial Ryegrass forage production can be improved with split applications of nitrogen. It is recommended that fertilizer recommendations be based on soil tests. However, rates approximating 45 pounds per acre of nitrogen following each grazing cycle has resulted in excellent overall production. If only one application is economically feasible, then apply 150 pounds of nitrogen per acre in the spring.

Organic Mara Perennial Ryegrass is most productive and nutritious when livestock are turned into well established pastures with six to eight inches of growth and quickly grazed to three inches. Livestock should then be removed to allow plants to regrow. Regrowth periods vary from about 14 to 28 days depending on the local climate and time of year. The peak growth period is from mid May through June. In the Intermountain West, during July and August, when temperatures exceed 80º F, Organic Mara Perennial Ryegrass production normally declines due to high temperatures, water stress and long day lengths. With proper fertilization and irrigation water management, Organic Mara Perennial Ryegrass will maintain fair growth during the heat of the summer. A second peak growth period can be expected when temperatures cool in the fall. Organic Mara Perennial Ryegrass can be allowed to attain twelve inches of growth, but should not be allowed to go to seed because the plants will not re-grow readily or maintain high nutrition and palatability.

The disadvantage of Perennial Ryegrass in the Intermountain West and Rocky Mountains is that it is not as winter hardy as other proven irrigated pasture grasses (orchardgrass, meadow brome, intermediate wheatgrass, pubescent wheatgrass and tall fescue). Winter hardiness data regarding Organic Mara Perennial Ryegrass is limited, thus recommendations of released varieties to farmers and ranchers are difficult. New Zealand varieties of Organic Mara Perennial Ryegrass tend to produce more than meadow brome, intermediate wheatgrass, pubescent wheatgrass and mountain brome the first growing season. However, in the Intermountain and Rocky Mountain regions, stands are commonly lost during the winter. In a trial near Shelley in eastern Idaho, the Mara variety persisted for more than 5 years, but it did not producing as much as other irrigated pasture grass species. Winter hardiness is thought to be associated with lack of dormancy in the fall and stands have also been lost during dry periods when adequate irrigation water was not available during growth.
