RM4 woolly pod vetch has better early establishment than present varieties (in 45 days form 3-5 nodes). It is earlier in flowering and grain/seed maturity, up to 10-15 days earlier than Haymaker/Capello. RM 4 is a soft seeded variety. It was selected and released as a new woolly pod variety for dry matter and seed production in areas of rainfall <380mm/yr as well in higher rainfall areas >400-650mm/yr.
RM4 is moderately resistant to ascochyta blight. It is susceptible in early growth stages to red- legged earth mite and alfalfa flea, like other woolly pod vetch varieties. Also, RM4 is susceptible to blue-green and cowpea aphids from early growth through to pod maturity, as well as to native budworm during pod formation and filling.
The recommended planting rate for RM4 Woolly Pod Vetch is: 15 – 35Kg per Hectare.
Sowing rates are related to the end use targeted and rainfall areas. Higher rates are required for hay/silage, grazing and green manure (30-35kg/ha) and 15-20kg/ha used for grain/seed production. Sowing time is the same as other woolly pod vetches.
Paddock selection and basic requirements for growing RM4 are similar to other woolly pod 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 reaches 20-25cm height it is competitive with broadleaf and grassy weeds. Suitable to graze from 15 nodes up to finish of flowering. For hay/silage, cut in full flowering for the best balance of feed value. RM4, like other vetches is excellent for soil fertility/structure and nitrogen fixation. Turn into soil or desiccate at flowering time. RM4 was not sensitive to any herbicides recommended/registered for use in woolly pod vetch varieties.
RM4 can be successfully grown, like other woolly pod varieties in many soil types. RM 4 performs better in grain productions than other woolly pod varieties when season finishes sharply.
RM4 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.
