Rasina (Vicia sativa) is a common grain Vetch variety derived from crosses between Languedoc and Morava. It demonstrates mid season maturity along with a semi erect growth habit, climbing branched, slender stems providing high quality hay or grazing for live stock. It is well adapted to a wide range of soil types, performing best in moderately fertile soils. Rasina is well adapted to low rainfall situations and has been selected for resistance to Rust (Uromyces vicia-fabae) and Ascochyta (Ascocchyta spp.). Rasina is a very soft seeded variety which makes it well suited to short term cropping rotations whilst providing the added benefits of moderate drought tolerance, being a highly efficient and effective soil nitrogen producer.
- Name: Rasina
- Category: Common Vetch
- Rainfall: 300mm+
- pH: 5.0 – 8.0
- Maturity: Early
- Soil Type: Light sandy loams to heavier clay soils
- Inoculant: Group E Rhizobium
- Sowing Rate: 30-40 kg/ha (Pure) 10-20 kg/ha (Pasture Mixes) 15-30 kg/ha (Cereal Mixes)
- Pest Resistance: Rasina, as with all common Vetch varieties, is susceptible to Red Legged Earth Mite (Halotydens destructor), Native Budworm (Helicoverpa punctigera) and Lucerne Flea (Sminthurus viridis). Appropriate control measures should be taken, especially in seedling stands.
- PBR Rasina 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. Seedmark (Seed Technology and Marketing) has an exclusive license for the production and marketing of Rasina.
- Earlier in maturity by 10-15 days than Morava
- Replacement variety for Blanchefleur and Languedoc in low medium rainfall areas
- Higher grain yields compared to Blanchefleur and Languedoc
- Resistant to rust and ascochyta
- Soft seed variety and non shattering
- Strong Winter growth and production make Rasina a better early grazing, hay or green manure option than both Languedoc and Blanchefleur
- Due to is early establishment vigour, Rasina is a productive addition to cereals for hay in low rainfall areas. Rasina is also soft seeded
making it a good green manure option
- Disease Resistance/Tolerance:
Rasina, unlike Blanchefleur or Languedoc, is rated as resistant to Rust (Uromyces viciafabae) and Ascochyta (Ascochyta spp.), however, as with all common Vetches, it is susceptible to Chocolate Spot (Botrytis vicae).
- Variety Management/Agronomy:
Rasina Vetch has 90-95% soft seed. This is a significant advantage in the reduction of volunteer vetch plants for following seasons for short term cropping rotations. Rasina pods demonstrate a longer non shattering period compared to other Common Vetch varieties Blanchefleur and Languedoc meaning that seed harvest can be delayed slightly without suffering from a significant yield penalty.
Vetch is not suited to close grazing as its growing points are well above ground level. However, in longer season environments Rasina can be lightly grazed successfully during winter and early spring provided the growing points are not damaged. Heavy grazing can cause significant damage to the plant and it may not recover. Bloat can be a problem on pure legume stands and stock will have to be watched carefully if grazing green Vetch paddocks.
