Hybrid maturity is based on heat unit accumulation through the season. Hybrids will therefore be quicker to harvest in warmer regions or warmer seasons. For example, a hybrid planted in coastal Bay of Plenty will be ready for harvesting much earlier than the same hybrid planted on the same day in Central Taranaki due to the faster accumulation of heat units in the Bay of Plenty environment. This has important implications for hybrid selection. The table above is a guide as to the estimated days from planting to harvest for Pioneer® brand hybrids in the regions for which they are recommended for silage. This information is generated from silage hybrid trials carried out in these regions over several seasons.

Trait characteristics notes:

1 Silage comparative relative maturity (CRM): Pioneer silage CRM ratings provide a comparison between Pioneer hybrids indicating the relative rates at which hybrids reach harvestable whole plant drymatter. They do not represent actual calendar days from planting to harvest.

2 Yield for maturity: Hybrid comparisons should only be made within a range of + or – 4 CRM. Analysis of differences in harvest drymatter percentages between hybrids measured in our New Zealand forage research programme show products compared within + or – 4 CRM will reach ideal silage harvest maturity (defined as 32% - 38% DM) within about seven days of each other.

3 Adaptability to high population: A measure of the mix of genetic factors that permit a maize plant to withstand the stresses of high population and still give good standability and high yields.

4 Adaptability to low population: An indicator of a hybrid’s ability to compensate (flex) cob size for stand loss from insect damage or poor emergence.

5 Early growth: Ratings are taken when two leaf collars are visible.

6 Plant height: 9 = Tall. 1 = Short.

7 Staygreen: A measure of late season plant health. A lower score also means that the plant stover loses colour and dries down more rapidly at maturity.

8 Whole plant digestibility: Based on estimated 24 hour in vitro, whole plant digestibility percentage (DM basis) as predicted by Near Infrared Reflectance Spectroscopy (NIRS).

9 Fibre digestibility: Based on 24 hour enzymatic estimate of the proportion of degradable neutral detergent fibre (NDF) as a percentage of the total NDF in whole plant sample, predicted by NIRS.

10 Silage crude protein: Based on the amount of crude protein in the whole plant, predicted by NIRS.

11 Readily available energy (RAE): Based on total starch, sugar and oil content of hybrids harvested at silage maturity. Use this score as a relative comparison of the whole plant concentration of more readily available energy (primarily grain) among individual hybrids.

12 Northern Leaf Blight (NLB) and Eyespot: Caution: In conditions where NLB and Eyespot risks are high, growers should only consider planting hybrids with at least moderate resistance ratings of 5 or higher for these diseases.

13 Hybrid disease resistance ratings: 8 to 9 = Highly resistant. 6 to 7 = Resistant. 4 to 5 = Moderately resistant. 1 to 3 = Susceptible. - = Insufficient data.

Common Rust ratings are mostly based on United States and European data as the New Zealand database is usually too small to give a statistically valid rating. Eyespot and NLB ratings are based on overseas data together with New Zealand observations. Scores are based on visual assessment only and not on yield reduction data.

14 Cool environments: In cool environments, including high altitude sites greater than approximately 150 m / 500 ft above sea level, select your yield environment using the descriptions in note 17, then increase established plant populations to the next level i.e.for P0791 in a medium yield environment at high altitude, plant to achieve 108,000 established plants per hectare.

15 Established plant populations: These assume good seed establishment conditions. If you are planting very early or into a less than ideal seedbed or where insect pressure may be high (e.g. a shorter than optimum fallow period), plant populations may need to be increased to compensate for reduced establishment due to field losses.

16 Plant populations: The tabulated established populations are recommendations only. Work with your local Pioneer Representative or Merchant Seed Representative to determine the appropriate plant populations for your specific growing environment.

17 Growing environment definitions: May include some or all of the following characteristics:

Challenging yield environments (CYE) Typically light, sandy or shallow soils of low fertility, low moisture retention, and predictably

low summer rainfall (drought-prone environments). High cob or leaf disease pressure.

Medium yield environments (MYE) Average fertility soils with predictably adequate

summer rainfall and good moisture retention. Continuously cropped soils. Medium to low cob or leaf disease pressure. Recommended for new maize growers.

High yield environments (HYE) Typically deeper, highly fertile and well structured soils with good moisture retention. Predictably good summer rainfall, shelter from high wind run. Good soils straight out of long term pasture. Low or no cob or leaf disease pressure.

For more than 80 years Pioneer breeders have improved the agronomy, disease resistance and yield of commercially available maize hybrids. The annual rate of silage yield gain in New Zealand is estimated to have been over 300 kilograms of drymatter per hectare per year over the last 50 years, as shown in the graph below. While crop management (e.g. planting date, nutrient balancing, weed control, precision agriculture and harvest timing) has made a significant contribution to yield increases, the largest slice is due to the breeding of both more defensive and higher yielding hybrids. As a result, a newly introduced Pioneer hybrid will have a considerable yield advantage over older hybrids.

Source: New Zealand Year Book and Pioneer® brand products New Zealand Research Programme.

To maximise their returns, silage growers should look to introduce new hybrids that are best suited to their farm system on a regular basis. Desired harvest timing, soil type, cultivation methods, agronomic traits such as early growth, drought tolerance, stalk and root strength, disease resistances and silage quality are all important considerations in the hybrid selection process.

The most reliable way to select superior hybrids is to consider yield and quality performance information, gathered over several seasons and over a wide range of locations within a growing region. Individual on-farm trial results should not be used to select a hybrid because they are not a reliable predictor of hybrid performance in future seasons. A useful rule of thumb is that at least 20 locations of data are required to provide adequate comparative yield performance information. This data should then be statistically analysed to establish the quality of the data and if there are any real yield differences between the hybrids being compared.

This publication provides a summary of the investment made to evaluate the silage yield performance of Pioneer® brand products and other brands of silage hybrids in five defined growing regions in New Zealand (see map on page 10).

It is Pioneer’s policy to only publish statistically significant results when comparing a Pioneer hybrid with that of another brand (please see page 12 for more information). As a result, we do not make any hybrid comparison inferences based on only a few trials. Consequently, comparisons involving new hybrids may take several seasons to generate sufficient data to publish.

New for spring 2015, P0725 is an Optimum AQUAmax® hybrid delivering impressive performance with extraordinary yield consistency for silage and grain in all warmer northern production regions.

The Optimum AQUAmax® range now includes P9911, P0791 and P0725. The drought tolerance in these hybrids provides resilience when it’s dry and yield responsiveness under favourable growing conditions. P0791 is now a popular choice in northern growing regions as a result of its exceptional staygreen and ability to “hang in” when it’s hot and dry. P9911 certainly caught the eye and delivered in water limited situations in its first commercial season.

The following hybrids that were extensively grown for the first time during 2014/2015 have all performed to expectation during a very challenging season. They merit further consideration for more extensive planting in spring 2015.

P7524: Intermediate in maturity between 39V43 and 39G12. A great option for growers in cooler high latitude or high altitude growing environments.

P8805: Intermediate in maturity between 39T45 and 38V12. A tough yet top yielding hybrid for silage and grain that has excellent all round agronomics and a balanced disease profile.

P9721: Similar to 37Y12 but delivers higher silage and grain yield. A great all-round balanced package of agronomic traits with wide adaptability.

P9911: A key maturity option in the Optimum AQUAmax® range delivering great drought tolerance. An impressive all-round hybrid with top agronomics and a sound disease package. Combines the best of bulk and energy for maximum milk productivity.

P1636: Combines impressive agronomics, drought tolerance and provides a wide harvest window. Similar in type and maturity to 33M54 and is particularly adapted to Northland, Waikato and Bay of Plenty.

All new Pioneer hybrids have been extensively tested and offer performance advantages over similar established hybrids.

We recommend this publication be used in conjunction with the Pioneer® brand Maize for Silage 2015/2016 catalogue and the expertise provided by Pioneer, as well as your local Merchant Representatives.

hybrids to watch out for

Pioneer Hi-Bred International Global Breeding Programme Thousands of new hybrids evaluated each year.

New Zealand Maize Silage Hybrid Evaluation Programme

IMPACT trials test up to 100 experimental and commercial hybrids. The best new hybrids are advanced for PAT testing in the next season.

PAT trials evaluate the best new hybrids grown side-by-side with existing commercial hybrids in on-farm strip trials.

Side-by-side trial data collected from at least 20 locations, over several seasons, within a growing region, is pooled to create an average yield result for the two hybrids.

A t-test analysis is used to calculate the statistical significance of the measured, pooled side-by-side yield result. Statistical significance is indicated by significance stars.

New Zealand Maize Silage Grower 22 tried and tested high yielding maize silage hybrids available to local growers in spring 2015.

New zealand maize research programmE


The 2014-15 season was characterised by generally cool early spring conditions. This resulted in slow growth through to mid-December. However, the late December to February period was considered hot and dry. This accelerated crop development resulting in a well set crop in mid-January. Limited rain delivered water stress during the all-important grain-fill period.

The trial yield results reported in this publication range from poor to exceptional. The exceptional crops often trace back to optimum planting dates into paddocks of good water holding capacity and with the application of the best agronomic practices, overlaid with sufficient rain and heat to grow the crop. Later planted crops were even more impacted by the dry conditions during critical development stages.

Pioneer® brand products’ ongoing commitment to sourcing and effective testing of hybrids in New Zealand provides growers with the opportunity to maximise maize silage yield and quality. The IMPACT™ trials (Intensively Managed Product Advancement, Characterisation and Training trials) together with the PAT (Product Advancement Trials) testing programme marks a unique team effort between research, sales, growers and contractors.

IMPACT™, or replicated small plot trials, provide local testing of up to 100 hybrids. The best experimental hybrids are advanced to strip or PAT trials for further and more extensive testing the next season. The silage PAT’s only evaluate 6 to 8 hybrids at a time but are over a wider geographic spread in growing regions where the new hybrid is expected to have a performance advantage over existing commercial hybrids.

The IMPACT™ programme is an advanced method for evaluating maize hybrids in replicated research plots. These trials are planted using specialised pneumatic 4-row research plot planters with GPS guidance for increased accuracy and precision in a range of environments with different soil types, weather and disease pressures. As the name implies, they benefit from intensive management, close observation and evaluation throughout the growing season. At the end of the growing season, specialist forage harvesters measure hybrid yield as the plots are being harvested.

The geographical spread of IMPACT™ trials is enabled by the availability of equipment transporters facilitating these trials at locations from Waikato, to the Lower North Island and for the first time this season the South Island.

Together, these trials funnel local information into the product commercialisation decision making process. It allows Pioneer® brand products to bring proven, industry-leading maize genetics to the New Zealand market and to understand which products offer the best performance in each growing region. As a result, specific customer needs can be more readily targeted and in doing so, the grower will experience the benefit of our “Right Product, Right Paddock” strategy.

The aim of the trial programme is to identify the best maize hybrids for New Zealand growing conditions. We achieve this through the combination of comprehensive field observation, as well as rigorous data evaluation and statistical analysis of the results generated, as shown in the flow chart above.

MAIZE SILAGE growing regions

The most reliable way to select superior hybrids is to consider yield and quality performance information, gathered over several seasons from a range of locations within a growing region. Individual on-farm trial results should not be used to select a hybrid because they are not a reliable predictor of hybrid performance in future seasons. A useful rule of thumb is that 20 locations of data are required to provide adequate comparative yield performance information. This data should then be statistically analysed to establish the quality of the data and to establish if there are any real differences between hybrids being compared.


Trial results

In order to ensure accuracy in trial planting, in-season note taking, plot harvest, field-weighing and silage drymatter determination, the Pioneer Field Technicians follow ISO 9001:2008 approved best practice procedures. All farmer trial co-operators receive a copy of their individual results. This information represents the outcome of comparing hybrids included in that one environment, in that particular season and under the management practice employed by the grower.

The results of IMPACT™ trials have not been published, as most hybrids are only experimental they will not be tested again and as a result are not of direct interest to the maize growing community.

When using trial results, it is essential that the overall performance of a hybrid over several seasons and sites in your growing region is considered, as this is more likely to be a robust and stable indicator of future performance in your paddock.

Side-by-side comparisons

In a valid side-by-side comparison, two hybrids similar in maturity are planted side-by-side in the same paddock according to strict scientific protocols. At harvest, crop yield, drymatter and nutritional characteristics are measured. This allows the performance of the two hybrids to be compared under the same growing conditions. Side-by-side trial data collected from a number of locations over several seasons, within defined growing regions, is pooled to create an average side-by-side yield result for the two hybrids.

A statistical analysis (called a t-test) is used to calculate the statistical significance of the measured, pooled, side-by-side yield result. This may sound complicated but statistical significance, indicated by significance stars ( ), simply shows how likely the measured average of the side-by-side yield difference is, due to an actual genetic yield difference between the two hybrids, rather than just chance. In other words we are essentially asking:

“Based on the data, are these two hybrids the same or different for yield?”

TRIAL RESULTS, SIDE-BY-SIDE COMPARISONS and statistical significance

Pioneer research chopper harvesting a maize silage trial

Interpretation of the t-test stars ( ) for hybrid side-by-side yield comparisons

Where a result is commercially acceptable (CA), the result is not designated as statistically significant, but it may be regarded as commercially acceptable.

Where a result is not significant (NS), we cannot conclude there is a yield difference between the hybrids. There are two principle implications;

1. Where the yields are very similar, and the comparison has been made over more than 20 locations, no significance may indicate there is little measurable difference between the two hybrids (i.e. they yield about the same) or;

2. Where there appears to be a yield difference, no significance will generally indicate there are too few trial locations involved, or there have been inconsistent

or fluctuating results. It is therefore, not possible to confidently indicate whether the difference is real. In this instance, growers should use the important hybrid trait ratings to select which hybrid to plant. On the other hand, yields may appear to be very similar but still achieve significance – this happens in cases where yield variations are small and the number of trial locations is large.

A t-test analysis of statistical significance is now carried out on all Pioneer side-by-side comparisons and we take great care to base our product yield statements on the outcome.

The table below presents a summary of the possible t-test outcomes.

The more stars ( ) present for the comparison, the more confident we can be that the measured average side-by-side yield difference is due to an actual genetic yield difference between the two hybrids rather than just chance.

INTERPRETATION OF PAIRED COMPARISONS Where stars are shown below each comparison, this indicates the level of confidence that a real yield difference actually exists

between two hybrids based on the yield data. Yield superiority can only be concluded where one to three stars are present.

SELECTING THE BEST HYBRID – TRIAL NUMBERS ARE IMPORTANT

Page 9

SELECTING THE BEST HYBRID – TRIAL NUMBERS ARE IMPORTANT Another way of interpreting side-by-side comparisons is to assess the probability of selecting the right hybrid based on the data. The two key factors which improve the probability of selecting the right hybrid from the comparison are the number of locations involved and the size of the measured yield difference.

The table below presents the probability of selecting the right hybrid from a series of side-by-side comparisons based on these two factors.

Probability of correctly selecting the better hybrid in a silage hybrid side-by-side comparison given a specified number of trials and the measured yield difference.

Simply stated the reason we’ve strongly emphasised the importance of using multi-location data for the comparison of interest is that it is the best and most practical way of increasing your chance of selecting the highest performing hybrid.

For example where a hybrid has a yield advantage of 500 kg of drymatter per hectare – 10 trials of yield data gives a probability of 63.1% of choosing the higher yielding hybrid. This rises to 95.2% with 25 trial comparisons.

This is the tool that Pioneer® brand products uses to help growers make thebest hybrid choices. We use paired comparisons, over as many paddocks as possible, within the growing region and area of adaptation of the two hybrids. This generates data which gives growers the highest probability of selecting the winning hybrid.

The table also shows that it takes fewer locations to confidently identify superior hybrids with large yield advantages, than when searching for small differences.

The table on the next page shows the format in which the analysis is presented in this publication.

(kilograms of drymatter per hectare)

The table indicates;

• The hybrids being compared (P9400 and 37Y12)

• The number of seasons of data included (6)

• The total number of comparisons made between the two hybrids (42)

• Average harvest drymatter for each hybrid (37.5% and 36.7%)

• The yield advantage in kgDM/ha (1631)

• The milk profit advantage per hectare ($774)

• The level of statistical significance as explained on page 12.

Comparisons are calculated based on trials where the hybrids were planted in the same strip trial.

The milk profit advantage reported relates to the potential value of milksolids produced from the reported drymatter yield advantage. Please refer to page 16 for the assumptions used in this calculation.

regression analysisThe regression analysis is used to describe the relationship between the yields of two hybrids, compared to the trial average yield in a series of trials where the two hybrids were grown together.

The regression graph below is made up by a number of important components;

The coefficient of determination (R2): This represents the proportion of the data that is explained by the lines of best fit. The higher the R2 the more confidence we have in the lines of best fit. If the R2 was 1.00 the yield line would perfectly describe the hybrid yield response and every data point would fall on this line.

The graph is plotted against the x and y axis where;

X axis = trial average yield (in kilograms of drymatter per hectare) which is the average yield of all hybrids in the trial. This is a measure of the environmental potential.

Y axis = yield (kilograms of drymatter per hectare) of the individual hybrid.

Along each axis the yield levels are indicated.

Each triangle or square symbol indicates an individual trial yield.

The hybrid regression line: The hybrid regression line characterises the expected yield performance of the hybrid presented as the average yield level changes from low to high. The regression lines of the two hybrids presented indicate the relative performance of each hybrid over the range of yield levels represented.

It is important not to extend hybrid recommendations beyond the boundaries of data points plotted on the graph. The regression is only accurate over the range of available trial yields.

MILK PROFIT CALCULATION

Hybrids summarised in this publication use the following equations to calculate milk profit ($/ha):

Milk Profit = Milksolids Yield/ha x Milk Payout - Silage Production Costs/ha *

Where Milksolids Yield/ha = Silage Yield (kgDM/ha) x 100 g Milksolids per kgDM fed

Milk Payout is based on an expected milksolids payout of $4.75/kg as announced by Fonterra on 30 April 2015

* A detailed listing of the cost for last season’s production was published in the Pioneer® Maize Silage 2014/2015 catalogue.
