Welcome to the inaugural edition of the Maize Hybrid Performance Trials results booklet.

The New Zealand Plant Breeding and Research Association (NZPBRA) administer trials such as the Cereal Performance Trials (CPT) for wheat and barley, and the National Forage Variety Trials (NFVT) for pasture grasses. We work closely with FAR and industry to set the technical guidelines for the Maize Hybrid Performance Trials (MPT).

The MPT is an independently verified system to compare hybrids and for the publishing of quality and yield results for farmers and participating seed companies.

Taking part in the trialling programme are seed companies with close-to-market or commercial lines of maize hybrids.

The MPT trials to be planted in spring 2015 will again include hybrids from Corson Maize Seed and Pacific Seeds. New to the programme will be hybrids from HSR Pty Ltd, distributed by Nutritech.

We welcome any queries or suggestions on how we might further improve this booklet. Please contact us if you have ideas, or if you require any additional information that we have not included in this booklet.

MPT

The Maize Hybrid Performance Trials (MPT) are organised and funded through the Maize Hybrid Performance Trial Committee with representa-tives from FAR, NZ Plant Breeding & Research Association (NZPBRA) and the participating seed companies.

Any organisation or company may join the committee if they agree to pay an appropriate share of the operating costs, participate in the running of the trials or contribute a service to the scheme.

Secretarial services are provided by NZPBRA.

Parties who are not members of the committee are welcome to participate as observers in appropriate meetings where their hybrids are under discussion. If their involvement becomes long-term, they will be invited to join the committee.

The committee will meet at least once a year to review the trial results, and at any other time that a meeting is required. The committee will view the field trial sites prior to harvest.

MAIZE TECHNICAL COMMITTEE

MAIZE HYBRID PERFORMANCE TRIAL PLANTING COMMITTEE

backgroundFor a number of years maize growers have been asking for an independent maize hybrid testing scheme. In 2014, FAR convened an industry discussion to explore the idea of having such a scheme open to all seed companies, similar to the cereal performance testing (CPT) programme that has been operating successfully for over 30 years. This meeting was attended by farmers, FAR staff, representatives from the seed companies, and members of NZPBRA and New Zealand Grain and Seed Trade Association. There was round-the-table agreement that a replicated small plot programme was preferable, and a smaller working group was convened and set about developing these ideas with the intention of having a hybrid trial programme in place for the 2014 maize planting season.

After the first meeting, operating procedures for a Maize Hybrid Performance Trial Programme (MPT) were developed and the format for the scheme was broadly identified. It was agreed that:

Purpose• To provide objective measurement of the

agronomic and quality performance of commercial maize hybrids available to the New Zealand arable industry across appropriate production regions.

• To foster industry adoption of proven hybrids to maximise industry efficiency and profitability.

• A pilot testing programme for maize grain and silage hybrids was to be established at four trial sites in spring 2014. These were in Waikato (2 sites), Bay of Plenty and Canterbury. The trial design was a fully replicated, small plot design which included agreed standard hybrids for comparison.

• Additional New Zealand maize grain and silage growing regions will be brought into the scheme as experience is gained with the trialling procedures.

• Any seed company may enter a hybrid into the scheme. It is expected that their hybrids will be backed up with their own trial data, and that seed will be either available commercially or be very close to (within 1 year) commercialisation. There will be a cost to entering hybrids into the scheme.

• An MPT committee of representatives from the maize industry will be established to govern the trial programme and the trial programme will operate under agreed MPT Operating Procedures. Analyses of the trial results will be carried out by an independent statistician.

The development of an independent maize hybrid testing programme is a considerable investment for the industry collectively but a well operated scheme should reduce individual company investment, and as a consequence grower investment, in developing hybrids. Seed companies will invest in the programme by paying to have their hybrids included in the scheme. Maize levy money will be invested in the governance of the programme, analysis of the results and reporting. We deliberately started with a pilot scheme which will enable the industry to evaluate the scheme’s purpose and value.

Please let us know what you think.

METHODOLOGYThe MPT comprises a single stage of hybrid testing administered through a single management committee. The committee recognises the purpose of hybrid testing and will not compromise the stakeholder requirements of the programme.

The trial programme focuses on the agronomic and quality characteristics of close-to-market pre-commercial and commercial maize hybrids. It isn’t intended to provide extra evaluation data for commercialisation decisions. These are made independently by the seed companies before the hybrids are entered into the MPT programme.

The trial programme evaluates silage and grain hybrids.

Harvest assessments are made at an agreed maturity value for the individual hybrids entered into the programme. These maturity values were determined by the committee and an agreed harvest schedule is developed at the start of the season. Weather and soil information, including mineral N tests, are collected for all trial sites.

At each trial site, four row plots are planted at 76 cm spacing, approximately 5 metres long. Each hybrid is replicated four times within a randomised complete block design. All data is collected from the middle two rows of the plot. Plots are planted from pre-counted packets of seed using a plot planter and harvested by hand.

Seeding rates are 100,000 seeds/ha in the Bay of Plenty and Waikato, and 120,000 seeds/ha in Canterbury.

guiding principles

• The trials are inspected and assessed by FAR during the growth period at establishment, early post establishment for weed control and silking date. Silking data is collected at one site only.

• Harvest assessments for grain and silage hybrids include: - Plant count - Ear rots and bird damage - Lodging - Yield

• For silage hybrids; a dry matter sample is taken from each plot and dried to constant weight using a standard protocol.

• For grain hybrids: all plots at each site are hand harvested on the same day. Grain moisture and test weights are measured with a Dickey John GAC 2100 Agri moisture meter.

• All information published by any party from the MPT programme must be clearly acknowledged as MPT data. The following statement must accompany any such publication:

Results given in the Maize Hybrid Performance Evaluation booklet are from a single year’s trials at three sites. One year’s data may not reliably indicate the performance of a hybrid due to environmental impacts, so wherever possible, use as many seasons’ data as are available when selecting hybrids. The results provide an independent and objective evaluation of the performance of the hybrids in the trials. In order to make good use of the results of these and other trials please consider the following:

1. Use multi-year data. These trials are from the first year of the MPT trial programme.2. Use multi-location average data. Consider single location results with caution. 3. Evaluate consistency of performance of the hybrids you are interested in over years, across locations in other zones. Look for hybrids that are consistently in the top group, and beware of hybrids that have widely varying performance across various sites and seasons. 4. Look at other reliable, unbiased, replicated independent trial results focusing on consistency. 5. Test new hybrids on your farm before planting large areas.

Remember you should avoid making hybrid selection decisions based on one year yield comparisons from only one or two local test plots.

DATA FORMAT The performance data for each trial site is reported in a single table. Hybrids in each table are listed by yield in descending order. Comparisons can be made only between hybrids within a table. Comparing two hybrids from different tables (i.e. different environments and/or production levels) would likely lead to a mistaken conclusion.

DAYS TO 50% SILK EMERGENCEPlease note the mean, LSD and CV given are for all the hybrids in the trial, not just those shown in the grain or silage results table.

UNDERSTANDING THE LEAST SIGNIFICANT DIFFERENCEThe least significant difference (LSD) listed at the bottom of each table for each column of data should be used to determine if the difference between hybrids is due to performance differences or random chance.

This booklet presents data with an LSD of 10%. If the difference between two hybrids were equal to or greater than the LSD, the difference would be attributable to hybrid differences in 90% of instances when the two hybrids are evaluated under conditions like those of the test.

Hybrids with the same letter beside them are not significantly different for the characteristic listed. When no significant difference for a given parameter is found among hybrids, “ns” (non-significant) replaces an LSD value.

A difference which is less than the LSD is likely due to chance.

For example, on Page 10 and 11, the hybrids C29-A1, 33M54, PAC 456, C78-S8, Z71-F1, PAC 343 and G49-T9 all have the letter ‘a’ beside them in the yield column. This indicates that while their yields in this trial varied, this variation is not statistically significant.

The “Coefficient of Variation”, or CV%, is another measure of the variability in a trial. If the differences between cultivars are similar across all replicates, the trial CV% is low (10%), there is a high level of unexplained variation, and the trial results are less accurate.

SILAGE HARVEST PROTOCOLS The aim was to harvest hybrids at approximately 35% dry matter.

The decision to harvest was made based on leaf and stalk state, and milk line in grain.

The hybrids within the trial represent a broad range of maturities and it is important to note that typically the longer maturity hybrids should have the greater yield potential as they are receiving sunlight energy, growing, and accumulating yield for a longer period of time than the shorter maturity hybrids.

While the data for the trials presented are sorted from highest yield to lowest yield it must be remembered that the highest yielding hybrids are not necessarily the best option for planting on your farm. The first consideration for selecting maize hybrids should be the maturity so that the hybrid selected fits your planting and harvesting timeframe in the environment in which you are growing.

The difference in maturity of the hybrids in the trial can be assessed by comparing the days to harvest and the DM content at harvest (DM%) for silage and the harvest moisture for grain. Wherever possible hybrids were harvested at the same DM content with a target of 35%.

silageUNDERSTANDING FORAGE MAIZE FEED QUALITYDRY MATTERThe residual dry weight of pasture, forage or silage after removal of moisture is usually expressed as % of the fresh weight.

The dry matter intake of a cow, for example, depends on many variables including live weight, stage of lactation, level of milk production, environmental conditions, feeding history, body condition and the quality of the feed.

METABOLISABLE ENERGY (ME)ME is an estimate of the energy content of the feed potentially available for maintenance and production in ruminant animals. It is that proportion of feed energy absorbed from the digestive tract and retained for metabolic processes and the value is expressed as a proportion of the dry matter (MJ/kg). Although ME is a frequently sought measure of feed quality, it is a value derived from other feed factors such as in vivo digestibility and cannot be measured directly. As such it has a number of limitations.

We measured the ME of each plot harvested for silage, and found a larger effect from the harvest dry matter on the ME value, than differences between hybrids. Therefore we have not published the ME results this year. In future we aim to harvest at a more consistent dry matter (35%) to allow comparison of different feed values between hybrids.
