Winslow Luisetti Feed Wheat Range

Key Features

  • High yield of feed grain for pigs, desired by industry
  • Suit mid April – late May sowing on all soil types
  • Medium height triticale with stiffer straw
  • Good levels of resistance to common leaf diseases
  • Strong take-all resistance, well suited as 2nd or 3rd cereal
  • Large grain with good resistance to shedding

With a strong root system they are particularly suited to early sowing (mid-April onwards) on light to medium soils and can also yield well on heavier soil types and leave an increased root mass.

It responds to nitrogen, water and PGR inputs as normal while fungicide inputs can be reduced and with higher resistance to take all than wheat, WINSLOW makes a good option as a 2nd or 3rd year cereal.

Trial results show an average 20% yield above feed wheat in 8-10 t/ha sites, with a similar yield to feed wheats in 11-13 t/ha sites.

Sowing

WINSLOW is a long season winter triticale, best suited to sowings from mid-April to late May, but can be sown in June. It should not be spring sown. Early plant development is quite prostrate (flat) until mid tillering. It is typically harvest mature 3-5 days earlier than European winter feed wheats sown at the same time.

Mid to late April sowing: establish 100 to 125 pl/m2 using 90 % emergence. (75-85 kg/ha)

Early to late May sowing: establish 125 to 175 pl/m2 using 85 % emergence. (90-110 kg/ha)

(Refer to “Fertilizer” section for spring tiller management advice, especially if plant counts are low).

Autumn Insecticde

Use Gaucho treated seed if aphid and grass grub are expected. If sown with Gaucho before mid-May, follow-up with at least one foliar aphicide at GS21. Check www.aphidwatch.co.nz for aphid activity.

If not using Gaucho, then use an insecticide (e.g. Karate Zeon at 20-40 mls/ha) at GS12, again 17-21 days later on early sown crops. (BYDV has most impact on younger plants, reducing after GS 32)

Growth Regulators

Needed on all early sown crops and where yields will be 9 t/ha plus. 1.25 l/ha Cycocel + 200mls/ha Moddus at GS 30-31 (32 if missed) or higher rates and or split applications in early sown higher yield situations should be considered.

Fungicides

WINSLOW has good resistance to speckled leaf blotch, leaf rust, glume blotch, mildew and medium resistance to stripe rust and fusarium. Low fungicide inputs can be used on these crops but they should always be monitored for changes in race resistance. A medium rate fungicide between GS32-39 and another at ear emergence in most seasons is adequate for WINSLOW.

Irrigation

With strong fibrous root systems, they will handle drought conditions better than many cereals. They will also respond to water like any other cereal with 50 mm of water required from soil or sprinkler for every 1 t of yield produced. Little and often (25mm/week) is better than more less frequently (50mm/fortnight), especially on light soils. December (grain-filling month) water use is 5-6 mls/day in high yield crops.

Fertilizer

Base spring N requirements on estimated soil contribution and yield target.

High yielding crops need adequate N from GS 32 onwards or will suffer a yield penalty. Can spring soil test for mineral N, (av.75-150 KgN/ha (range 30-250).<70=earlier N, >150=delay N)

A 10 t/ha crop contains 250 kg N/ha (25 kg N/t). Fertilizer N is used at approximately 80% efficiency in irrigated conditions and approximately 60% in dry land conditions.

The aim is to produce 700-800 tillers at GS 31 (1st node) , and then grow them to the MAX, (allowing 20-25 % tiller death to produce 500-600 ears/m2at harvest)

Nitrogen Recommendations (timings can be 5-7 days earlier if rain anticipated)

GS 32 (2nd node) apply approx. 2/3 of total yield N (adjust time/rate for base fertility).

GS 39 (full flag) apply approx. 1/3 of total applied yield N.

Harvesting

WINSLOW has slightly lower initial falling number values than most feed wheats with similar sprouting resistance and good shedding resistance
