Sowing Guide 2014Sowing Guide 2014Vetch variety <strong>sow</strong>ing guide 2014By Rade Matic, Stuart Nagel and Gregg Kirby,SARDI National Vetch Breeding ProgramVetch is a multi-purpose cropgrown mostly as a disease breakcrop in rotation with cereals in awide range of soil types from light sands<strong>to</strong> heavier clay soils.Common Vetch varieties(Languedoc,Blanchfleur, Morava A ,Rasina A , and Cummins) versatility allowscropping for grain or hay production,early grazing as green pasture or fordry grazing, hay production or greenmanure.Grain vetches have been grown in lower<strong>to</strong> mid-rainfall cereal areas of SouthernAustralia, and their grain yields havebeen similar <strong>to</strong> pea yields in these areas.Note that vetch grain is not used forhuman consumption and has limited usein pig rations.Grain from Morava and Rasina can beused without limit <strong>to</strong> feed all ruminantsand as up <strong>to</strong> 25% in the diet of pigs.Forage vetches are used for hay,green manure or mid <strong>to</strong> late winterfeed for grazing. They are purplevetch (V. banghalensis) variety Popany,or Woolly Pod vetches (V. villosa ssp.dasycarpa) varieties Namoi, Capello ® orHaymaker ® . Forage vetches can growsuccessfully in areas of 400 <strong>to</strong> 650mm ofannual rainfall. Grain from woolly podvetch varieties CAN NOT be used <strong>to</strong> feedany lives<strong>to</strong>ck.Morava and Rasina are resistant <strong>to</strong> rustand are the preferred varieties for grainin areas prone <strong>to</strong> rust infections.Disease management is critical whengrowing a vetch crop regardless of theend use, where possible diseaseresistant varieties should beplanted as a preference.Care must be taken whengrowing rust susceptible varietiesas grazing or feeding hay/silagefrom rust infected plants mayinduce abortions in pregnantlives<strong>to</strong>ck. So while it is usuallynot economically viable <strong>to</strong> use fungicidesfor rust on vetch it may be necessarywhere rust susceptible varieties are <strong>to</strong> beused as feed.Ascochyta blight occurs in earlier stagesof the vetch crop and can reduce grainand dry matter production, but not likea heavy infestation of Botrytis grey mould(BGM) can in cool/wet growing <strong>season</strong>swith high amounts of vegetative growth.There is little difference between vetchvarieties in their resistance <strong>to</strong> BGM;varieties like Morava, which producegreater levels of vegetative growth anddenser canopies, will be more prone <strong>to</strong>this disease in higher rainfall areas.When selecting a vetch variety growersalso need <strong>to</strong> consider their individualfarm and paddock situation and mostimportantly the end use targeting for thecrop and <strong>to</strong> make this selection on all theavailable information.Notes on varietiesCommon vetch (Vicia sativa)Table 1. Vetch grain variety rainfall zones (mm).600Languedoc Rasina Morava Morava MoravaRasina Blanchefleur Rasina RasinaCummins Cummins BlanchefleurLanguedoc CumminsMoravaRade MaticLanguedoc. Languedoc is an earlyflowering and maturing varietyrecommended for low rainfall areasalthough it can lodge severely makingharvest difficult under certain conditions.Languedoc generally exceedsBlanchefleur’s grain yield inareas with less than 350mmrainfall. Its hard seed content isgenerally around 5-10% and it ishighly susceptible <strong>to</strong> rust.Blanchefleur. Prior <strong>to</strong> therelease of Morava, Blanchefleurhad been the preferred grain varietyin areas above 350mm rainfall in SA.Blanchefleur has mid maturity, whiteflowers and reddish brown/mottled seedwith orange cotyledons.Blanchefleur is very susceptible <strong>to</strong>rust. It is well suited <strong>to</strong> medium <strong>to</strong> highrainfall areas where rust is not a regularproblem. Both vetch and lentils are onthe prescribed grain list of AQIS due <strong>to</strong>the vetch-lentil substitution issue, thishas meant export markets of orangecotyledon varieties like Blanchefleur arelimited <strong>to</strong> small bird seed markets inEurope and seed for grazing and greenmanure crops only.Cummins. Cummins is a mid <strong>to</strong> earlymaturing, white flowering variety selectedfrom Languedoc. It is well adapted <strong>to</strong>medium <strong>to</strong> low rainfall areas where itgenerally yields higher than Blanchefleur.Cummins is susceptible <strong>to</strong> rust andmoderate susceptible <strong>to</strong> Ascochyta blight.Morava A . Morava is a rust resistant lateflowering vetch variety with 100% softseeds, develop by SARDI’s AustralianNational Vetch Breeding Program(ANVBP).Grain yield is superior <strong>to</strong> othervetches in the high rainfall areas and <strong>to</strong>Table 2.

Rasina is soft seededvetch from the ANVBP, and replacesLanguedoc, Blanchefleur and Cumminsin low <strong>to</strong> medium rainfall areas forgrain production. Rasina is earlier for5-10 days than Blanchefleur and 10 <strong>to</strong> 15days earlier than Morava. A significantadvantage over Languedoc, Blanchefleurand Cummins is Rasina’s resistance<strong>to</strong> rust and slightly more <strong>to</strong>lerant <strong>to</strong>Ascochyta blight and Botrytis.However, Rasina is not expected<strong>to</strong> replace Morava in higher rainfalldistricts or for hay production. The levelof anti-nutritional fac<strong>to</strong>rs is 0.6 <strong>to</strong> 0.8compared <strong>to</strong> 0.9 <strong>to</strong> 1.6 in Blanchefleurand Languedoc, respectively.Rasina possesses a distinctive uniformdark brown speckled seed coat with darkbeige cotyledons.Rasina is a PBR variety and can besourced from Heritage Seeds.Purple Vetch (Vicia villosa subsp.banghalensis)Popany is purple vetch. Grain yieldis significantly lower than yields fromcommon vetch varieties.But, seeds are smaller than seeds fromcommon vetch varieties therefore theseeding rate is lower at approximately30-35kg/ha.Grain from this variety can beused as a bird feed in mix with otherrecommended grains. Popany is a latematurity variety, >125 days from seeding<strong>to</strong> podding.It is a good variety in mid <strong>to</strong> highrainfall areas for hay/silage. Popany,possesses 5-10% hard seeds. This varietyis resistant <strong>to</strong> rust but susceptible <strong>to</strong>ascochyta and chocolate spot.Seed coat is black with distinctive whitehilum.Table 3.
