MAIZE HYBRID

GUIDE

Corson Maize Seed is committed to providing New Zealand growers a range of premium maize hybrids for both silage and grain production. In recent years we have introduced a number of new silage hybrids including G49-T9, N23-K3, Z71-F1 and L07-A9, dual purpose maize silage and grain hybrids N39-Q1, C29-A1 and maize grain hybrid N51-N4 which is one of the leaders in the mid-maturity grain market sector.

Feedback from around the country has been positive from many growers who have planted Corson Maize Seed hybrids, especially in terms of their performance during challenging seasons.

Trialing, testing and evaluation of world class maize and sweet corn hybrids is an ongoing focus and we are dedicated to providing even more production improvement options to growers in the future. As part of this, we are excited to introduce two new products this season; C56-C4 which is a top performing mid-late maturity silage hybrid with the ability to go through for grain and C78-S8, a strong performing full maturity hybrid with excellent silage and grain yields.

For more information go to www.corsonmaize.co.nz and remember to contact a Corson Maize Seed Sales Agronomist on 0800 805 505 for any assistance with your hybrid selection this season.

We wish you all the best for the season ahead.

Making Maize Easy

Maize is a very specific and detailed crop. This sometimes creates the perception of it being difficult

to manage, however at Corson Maize Seed it’s our aim to make maize growing and utilisation easy. Our team have a wide range of skills and experience in maize, and other forage crops to ensure farmers use the appropriate crop for their needs and achieve the best results from our products.

Our product development team are constantly developing new hybrids and sourcing hybrids from a number of maize seed companies around the world. These products are then tested in New Zealand through our evaluation programme. Our team understand the needs of New Zealand growers and are always looking for improved field performance of our hybrids through both dry matter (DM) yield and plant traits.

Our field team have a detailed understanding of the products we have to offer and how to get the best results from them. We can offer helpful advice from growing a successful crop through to harvesting, storing and feeding maize silage. This knowledge and advice also extends beyond maize to all forage crops, to help gain the highest return from a farm system.

CORSON MAIZE SEED PLANTING RATES At Corson Maize Seed we are yet to be convinced that the often reported yield response at higher plant populations are reflected in commercial crops. This is especially the case when considering plant health factors and the impact these have on drought tolerance, standability, disease tolerance and overall resilience of the crop.

Corson Maize Seed’s published planting rate recommendations are general in nature. A detailed understanding of the growing environment is required for a specific planting rate recommendation. This should be assessed by the grower and their advisors.

MAIZE SEED TREATMENT

Corson Maize Seed is treated with leading Seed Treatment products Poncho® and Vitaflo®, which play an important role in maximising plant establishment and crop yield. Poncho® and Vitaflo® provide highly targeted protection against the major insects and diseases that affect young maize crops.

Poncho® protects against:

• Argentine Stem Weevil

• Black Beetle

• Greasy Cutworm

Poncho® contains the active ingredient clothianidin, providing a high level of protection against three major insect pests during crop establishment. Poncho® through it’s systemic mode of action and increased spectrum offers the best early pest protection currently available in the maize market.

Vitaflo® protects against:

• Head Smut

• Soil borne and seedling rot diseases (including Fusarium)

Vitaflo® contains the active ingredients carboxin and thiram providing protection against seed and soil-borne diseases during crop establishment. Carboxin has a systemic mode of action controlling seed-borne diseases at germination and seedling emergence. Thiram has contact activity against soil-borne diseases to extend the level of disease control and the disease spectrum. Vitaflo® stimulates early seedling growth which is particularly evident under stress conditions.

Avipel® Bird Repellent

Avipel® bird repellent is a new product which is available exclusively from Corson Maize Seed, treated on demand. Avipel® contains a naturally occurring organic substance. When birds eat seeds treated with Avipel® they experience an unpleasant but harmless gut reaction which they associate with the location. Birds quickly learn to avoid treated seeds and forage for other food sources.

Poncho is a registered trademark of Bayer and is registered pursuant to the ACVM Act 1997. Vitaflo is a registered trademark of Chemtura and is registered pursuant to the ACVM Act 1997. Avipel is a registered trademark of Arkion Life Sciences LLC.

• Very early maturity silage hybrid for Canterbury and North Otago

• Rapid early growth

• Consistent ear size

• Reduce the risk of growing silage in shorter season environments without compromising yield with L07-A9

L07-A9 is a new, early silage hybrid released for the South Island and lower North Island. Corson A9 has outstanding early growth for great establishment in cooler environments and its very early maturity provides reliability of silage production in regions with short growing seasons. It can also be utilised as a management option for early harvest or late planting in the lower North Island. Corson A9 develops into a plant of medium stature for its maturity with consistent, good sized ears to give an overall high yielding silage with high grain content from this very early hybrid.

L07-A9MAIZE SILAGE CRM 72

Neil Koevoet, Product Development and Production Manager - Corson Maize Seed

“Bred to suit short growing seasons, L07-A9 delivers relatively high silage yields from such an early maturity. As yield is often limited with early maturity hybrids, high feed value is critical in providing cost effective conversion of feed to milk production and L07-A9 brings with it the required feed values.”

• Very early maturing dual purpose hybrid

• High silage yield with reliable grain content for this maturity

• High test weight grain suitable for food grade markets

Delitop is a very early dual purpose hybrid for silage or a late planting option throughout the country. For grain, Delitop is accepted for food grade production in northern regions.

Outstanding early growth, above average drought tolerance and above average resistance to Northern Leaf Blight for this maturity.

Delitop has respectable yield performance for both silage and grain and produces high energy silage with above average whole plant digestibility.

“We put Delitop on some of our poorer land and were quite impressed with the way it performed. Early maturing Delitop suits us as we don’t plant until mid-November as it is too wet and cold before then.”

“N23-K3 got going early and quickly in spring and grew into a tall plant. I am pleased with how it has performed considering the season.”

Ian McCaw Ashburton, Mid-Canterbury

• Mid to late maturity silage hybrid for Canterbury, northern South Island, and lower North Island

• Vigourous early growth

• Well filled ears

• Tall plant with high silage yields

N23-K3 is a new hybrid from the Syngenta breeding programme, which will give growers in the South Island and lower North Island a great option for high yielding silage. With outstanding early growth CORSON K3 will be particularly suited as a mid hybrid for the mid Canterbury region and as an early-mid maturity option for the upper South Island and lower North Island. Above average tolerance to Northern Leaf Blight enables CORSON K3 to move into the northern North Island as an early maturity option. CORSON K3 is a tall plant that produces well filled ears giving this hybrid a high silage yield potential.

• Strong performance as an early maturity dual purpose hybrid

• Very tall plant producing high grain content silage

• Excellent silage and grain yields

Distinct with a very tall bulky plant and large, well filled ears, C29-A1 retains its plant health late into the season to maximise its huge silage and grain yield potential. While primarily targeted at the silage market, CORSON A1 does not compromise on grain yield and will deliver high yields of large, softer textured grain.

CORSON A1 will perform best on medium to heavy soil types and in other situations where there is adequate fertility and soil moisture to complete the growing cycle.

• Reliable silage yield with high grain content silage and excellent staygreen

Goldfrank is a tall, attractive plant that maintains its staygreen and overall plant health late into the season, offering a wide silage harvest window and insurance against a season with high leaf disease in northern regions for both grain and silage.

For grain, consider Goldfrank in situations where plant health is a key criterion or to provide balance alongside hybrids with poorer leaf disease tolerance ratings. Goldfrank is a good choice as a mid-season hybrid for contract silage production in medium to high yield situations.

• Very large plant with high grain yield and a sound agronomic package

• Excellent yield performance in this maturity

Z71-F1 offers above average early growth developing into a tall, bulky plant with large ears as well as excellent staygreen which contributes to a wide harvest window. CORSON F1 has a high grain content and above average whole plant digestibility.

CORSON F1 is suitable for warmer northern regions where early planting is possible. It is ideally suited to contract silage production, targeting high yields and quality silage. Dairy farmers can take advantage of its performance by planting early on a run-off.

“Z71-F1 yielded better than other varieties in one of our harsh blocks. About 40 hectares of CORSON F1 was grown, including one paddock yielding more than 30 tonne DM/ha. We put the crop over the scales so this was a weighed rather than an estimated figure and an exceptional result.”

Introducing maize silage into the diet

FEEDING MAIZE SILAGE:TWO ASPECTS OF ADAPTATION1. Behavioural adaptation – for cows or heifers who haven’t

been fed maize silage before

2. Ruminal adaptation – for microbial populations to adjust to the new feed

BEHAVIOURAL ADAPTATION• New cows and rising two year old heifers need time with

mixed age cows who are more experienced with a maize silage feeding system

• Expose heifers to maize silage several weeks pre-calving – they’ll be settled and consuming maize silage well, in time for calving


Nutrition

Nutrition

RUMINAL ADAPTION• Types of rumen microbes that utilise starch are different to

those that digest pasture

• Microbial populations take 10 - 14 days to change from pasture to starch digesters

• Sudden change to starchy diets may increase risk of ruminal acidosis (“grain overload”). Risk depends on maize silage feeding rates, total levels of dietary fibre (NDF), and on the presence of other starchy feeds

• Low rates of maize silage (less than 3kg DM/cow/day) typically won’t require adaptation

• Higher rates (more than 5kg DM/cow/day) increases requirement for adaptation

• Start cows on low rates of maize silage, building up to final rates over a few days. For example, if the target is 5kg DM maize silage/cow/day, start at 2kg DM for two days, lifting by a further 1.0 - 1.5kg DM every two days

• For calving cows, use time spent by cows in different mobs to gradually ‘step’ up silage feeding rates:

° Springers – start on lower rates of maize silage

° Colostrum cows – offer maize at 1-2kg DM/cow/day more than to springers

° Milking cows – offer maize at an additional 1-2kg DM/cow more than to colostrum cows

° Monitor the maize stack face when feeding silage at lower rates – slow feed out increases risk of aerobic spoilage/heating

MINERALS FOR MAIZE SILAGE – WHAT IS REQUIRED? Maize silage contains low levels of calcium, sodium and magnesium.

Supplementary mineral recommendations are not absolute for all situations, but reflect:

1. Quantity of maize silage offered

• Feeding maize silage as a higher proportion of the diet increases the need for mineral supplementation

2. Levels of minerals found in other feeds (including pasture)

• Feeding maize silage with other low mineral feeds increases the requirement for supplementation. E.g. extra sodium is more important when feeding maize plus other low sodium feeds e.g. PKE or inland pastures

3. Maize silage for different stock classes

• Lactating dairy and beef cows can need calcium, sodium and magnesium

• Springer cows only need magnesium

• Finishing beef cattle need sodium and sometimes calcium

Contact your Corson Maize Seed representative, a nutritionist or veterinarian for mineral recommendations specific to the feeding situation.

COMMON ADDITIVES FOR MAIZE SILAGE

Calcium (Ca)= Limeflour (35% Ca)

Sodium (Na) = Salt (39% Na) or sodium bicarbonate (27% Na)

Magnesium (Mg) = As magnesium oxide (52% Mg), chloride (12% Mg) or sulphate (10% Mg)
