Volga was bred as a high yielding grain/seed variety for low and mid rainfall areas. It is particularly suited to shorter season areas where the growing season finishes sharply. Volga has good initial establishment, is rust resistant, and earlier flowering and maturing than Blanchefleur and Rasina. It will improve the reliability of vetch and economic production in crop rotations especially in low and mid rainfall areas, 330 to 380mm per year.
Vetch flowering and maturity is ‘parallel’ with development of nodules for nitrogen fixation. Earlier maturing equates to earlier nodule development.
Volga is susceptible in early growth stages to red- legged earth mite and lucerne flea, like other common vetch varieties. Also, Volga is susceptible to bluegreen and cowpea aphids from early growth through to pod maturity, as well as to native budworm during pod formation and filling.
- Adaptable variety which grows on a wide range of soils
- High percentage of soft seed (24%) –Santiago (8.5%)
- Erect growth habit with high herbage and seed production
- Excellent ley farming option with dense regeneration
- Demonstrates excellent salt tolerance during key growing period compared to other species
The recommended planting rate for Volga Common Vetch is: 30 – 40Kg per Hectare.
Volga’s early flowering/maturity provides increased flexibility when compared to other varieties in relation to sowing time. Sowing rates are related to the end use targeted and rainfall areas. Higher rates are required for hay/silage, grazing and green manure and lower rates are used for grain/seed production.
Paddock selection and basic requirements for growing Volga are similar to other common vetch varieties. Good control of weeds in early growth stages is very crucial, as it is for other vetch varieties. Vetches are poor competitors to weeds in early growth stages, but when vetch has 15 nodes it is competitive with broadleaf and grassy weeds. For harvesting grain/seed, dry matter, grazing and green manure there are no differences between Volga and other common vetch varieties. For hay/silage, cut when there are 50% flowers and 50% small pods for the best combination of yield and feeding value. For green manure, turn into soil or desiccate at flowering time. Frost tolerance testing was conducted in Serbia for two years. Frost occurred for five consecutive days at -10C resulting in the following seedling survival rates: Volga 85%, Timok 82%, Morava 66% and Rasina 72%. Volga was not sensitive to any herbicides recommended/registered for use in common vetch and applied according to label directions.
Volga 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.
