Where to from here? Greg O’Brien & Frank Mickan
2
Options for next year? Try to get early feed next autumn? Try to produce more winter feed?
3
Try to get early feed next autumn? Forage cereals Early sown ryegrass Brassicas
4
Try to get early feed next autumn? Forage Cereals Cereals quick off the mark Can go in earlier & handle false break better than ryegrasses BUT may only get 1 - 2 grazings Sowing rate? What % of farm to be sown?
5
Don’t handle false break as well Produce less feed with late break Produce more feed with good break Try to get early feed next autumn? Early sown ryegrass
6
Is there a place for the new re-graze types? Good substitute for grain in the diet Maffra experience: Goliath sown mid-Mar and yielded 4t/ha by 26 April and 6 t/ha mid-May (NB ~50 mm irrigation in autumn) Try to get early feed next autumn? Brassicas
7
Goliath being strip grazed
8
Try to produce more winter feed? Cereals x2 sowings? Cereal + ryegrass? Plus the usual - Nitrogen - Correct grazing management
9
Grazing regimes for forages 2006 Grazed ONCE (Mid June ‘06), then closed for silage GS 21-22:Tillering Grazed TWICE (Mid June & Mid August, then closed for silage GS 21-22 & GS31 - 33:Stem elongation Final yield as silage GS 82 - 85:Soft Dough Oats What’s the message here?

Crackerjack Triticale sowing rates (60 - 160 kg/ha Sowing rate (kg/ha) Nil Nitrogen at tillering (GS 22), then N at GS 32 & 39 Lack of response to sowing rate may have been due to moisture constraints ?

17
Forage Monitoring points from data Huge variation in yields and qualities (Gippsland) High ME(11.1) at Flag leaf/Boot - lower at Early Flower (8.9) back to reasonable ME (9.3) at hard dough Protein is downhill all the way!(17.4 - 8.2%) Most farms from marginal dairying areas

19
Where’s he gone?
20
Crops from left field? Lucernes - Acid soil tolerant variety on way - SW Partner Farm experiences (grows over summer for autumn bank of feed; this dry spring growing at 40 cw <10 for prg)
21
More shoulder feed Spring or autumn sowing? Is there a place for mixes? Brassicas, herbs & grasses
22
Summer crop Dead Chicory Plantain Italian Ryegrass Clover (Red & White) Weeds Summer forage crops established in SPRING THEN Direct drilled with Italian Ryegrass & herb/clover mix in AUTUMN Turnip Rape Radish Turnip-rape Millet

24
What would you like modelled? Cereal/rye (early v late break; % farm?) brassica (feed flow issues, sensitivity to yield?) lucerne (whole farm economics) herb plus mixes (feed flow, whole farm economics?)

41
To investigate the potential of novel crops To investigate regional variations due to soil type, rainfall, etc. To provide insights for farmers and advisors To add depth to Management Info Packages To expose knowledge gaps Why?
42
What is being recorded? Physical growing conditions Soil type, rainfall, type of seedbed, etc. Sowing details Seed bed preparation, s eeding rate & depth, equipment used, fertilisers Management during growth & harvest F Fert’s, weeds, pest & disease control, grazing, etc. Management & Systems issues Labour, effects on farming system, ease & reliability of growing, attitude to risk, etc.

44
Triticale & Barley susceptible to army worms Wheat slower than Trit. but stronger heads If going for grain - high winds can cause grain drop - lighter yields Better as WCS - higher all round yield and quality - quicker out of ground Now know that Ryegrass is a problem due to moisture competition, especially in marginal areas Forage Monitoring: Farmer comments Wayne Bowden
45
Straw is an issue if grain harvested Amarok wheat resistant to rust - Gairdner Barley required fungicide, Amarok did not Probably going to RAISED BEDDING system Getting 5t/Ha grain yields but believes 7 - 8t/Ha is achievable Marshall Baillieu Forage Monitoring: Farmer comments
46
Using raised beds after very heavy rains 1 year - cost ~$150/ha to install - grazing knocks beds around Thinks grazing reduces yields by ~20 - 25% Will look at undersowing vs. oversowing after cereal already sown. Eg. Arrowleaf clover Red winter wheats tiller to compensate low seed rate Trevor Caithness Forage Monitoring: Farmer comments
47
Playing around with chook manure (+lime, gypsum, fertilisers, etc.) Gets a K response despite satisfactory soil test UK visit - 8 - 10t/ha grain yields (Vs 3 - 5t/ha) - UK grain:straw is ~1:1, vs ~1:2 in Aust. - Fungicide usage kept green leaves to the base vs 3 green leaves at the top only - Fungicide usage is preventative, Aust. is reactive Trevor Caithness Forage Monitoring: Farmer comments

53
Not a normal year! Low quantities of home grown feed High prices for purchased feeds Low availability of purchased feeds

Conserve more fodder next spring? Forage cereals cw Ryegrasses Effect of grazing on silage yield - Decision needs to be made in winter Timing of silage harvest affects yield and quality Implications for follow up crops
