Download a copy of the RM4 Woolly Pod Vetch factsheet.
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 and Capello. RM4 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.
The recommended planting rate for RM4 is: 15–35Kg per hectare. Sowing rates are related to the end use target 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.
Disease / Pest Resistance
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 bluegreen and cowpea aphids from early growth through to pod maturity, as well as to native budworm during pod formation and filling.
RM4 can be successfully grown, like other woolly pod varieties in many soil types. RM4 is better suited to cereal rotations in regions where the season can finish sharply.
