    Description:

     

    Nitro Plus (Trifolium resupinatum var. resupinatum) is a hard seeded Persian Clover that has a semi prostrate growth habit and demonstrates early to mid season maturity. This will offer large benefits to growers in medium rainfall cropping zones where pasture options are normally restricted to either Medic or early maturing Sub-Clover varieties for pasture rotations. It has an indeterminate flowering habit and can take full advantage of unseasonal rains late in the season. Nitro Plus produces large numbers of thin walled, hollow stems and smaller leaves compared to soft seeded Persian Clover varieties, which contribute to the plants prostrate appearance. It is well adapted to a range of soil types but prefers heavy alkaline soils. Nitro Plus will also tolerate waterlogging and mild soil salinity. It is very palatable and has a highly digestible feed (16-21% crude protein) that is well suited to hay, grazing or silage production and is very successful in pasture mixes with ryegrass or oats to increase dry matter production. It provides an effective disease break in cropping rotations and has the ability to fix high levels of soil nitrogen. Nitro will also assist in the management of problem weeds including those that are herbicide resistant.

     

     

    Maturity:

     

    Nitro demonstrates early maturity flowering between 68-142 days after sowing with an average of 114 days. As the flowering habit is indeterminate flowering times can vary depending on the season.

     

    Pest Resistance:

     

    Persian Clovers are susceptible to attack from Lucerne Flea (Sminthurus viridis) and Red Legged Earth Mite (Halotydens destructor). Control measures will need to take place as required.

     

    PBR:

     

    Nitro Plus has been granted protection under PBR. Unauthorised commercial propagation or any sale, conditioning, export, import or stocking of propagating material of this variety is an infringement under the Plant Breeder’s Rights Act 1994. Heritage Seeds Pty Ltd has an exclusive licence for the production and marketing of Nitro Persian Clover.

     

    Key Benefits:

    • Shows good early vigour
    • Offers excellent winter and early spring production
    • Adapted to a large range of soil types, especially lighter soils
    • Suitable for grazing, fodder, green manure and High Density Legume mixes
    • Excellent pioneering plant, especially on acid soil


    Key Benefits:

     

    • In low rainfall areas, Nitro Plus holds many benefits over competing varieties. It offers higher seed, winter and spring production and produces 74% more flowers by October than Paradana
    • In medium rainfall areas it provides higher dry matter in winter and spring over Shaftal and Paradana

     

    Disease Resistance/Tolerance:

     

    Nitro Plus is highly tolerant to Clover Scorch (Kabatiella caulivora) and is resistant to Sub-Clover Root Rot (Phytophthora clandestina). However, it can be susceptible to attack by Rust (Uromyces trifolii-repentis) under certain conditions.

     

    Variety Management/Agronomy:

     

    Nitro Plus is hard seeded and will not require re-sowing should appropriate management be undertaken. To maximise seed set in the year of sowing to ensure regeneration and long term persistence, stands should not be grazed during the flowering period. In established stands, light grazing can continue during the flowering period but should be avoided to ensure persistence.

     

    Once seed set is complete, plant residues should be either removed or grazed during late summer to promote better seedling regeneration. Nitro is well suited to grazing given its prostrate growth. It is also well suited to hay and silage production as its growth habit becomes more erect when ungrazed. Plants can be grazed during the winter/spring period or left to make hay or silage during the spring period. In the establishment year graze plants to control problem weeds but remove stock during the flowering period. Once paddocks are established moderate grazing levels can continue though the flowering period.

     

     

    Annual Ryegrass

    Annual ryegrass is generally sown for a high quality short-term winter crop, providing multiple grazings in winter and spring. It is generally used for 6-9 months prior to sowing a summer crop, or to make the most of a growing season rainfall where late season rain is unreliable.
