Consult with your Area Manager. NOTES Hybrid maturity is based on heat unit accumulation through the season. Hybrids will therefore be quicker to harvest in warmer regions or warmer. 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 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.

4 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 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 s 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

6 NEW HYBRIDS INTRODUCED FOR SPRING 2015 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 (from Pioneer research and published crop yield data). As a result, a newly introduced Pioneer hybrid will have a considerable yield advantage over older hybrids. 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 traits 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 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. 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 differences between hybrids being compared. This publication provides a summary of the investment made to evaluate the silage yield performance of products and other brands of silage hybrids in defined growing regions in New Zealand. For spring 2015 a number of new silage hybrids will be introduced for the first time: P7524: Intermediate in maturity between 39V43 and 39G12. An exciting new option for growers in cooler high latitude or high altitude growing environments. P8805: Intermediate in maturity between 39T45 and 38V12. A 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 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 and Bay of Plenty. All have been extensively tested and offer performance advantages over more established hybrids. We recommend this publication be used in conjunction with the Maize for Silage 2014/2015 catalogue and the expertise provided by Pioneer as well as your local Merchant Representatives.

7 Growing Season No two are quite the same. The season was however, similar to in much of Northland and Waikato with good early growing conditions but became hot and dry over the January to March period. Once again in these regions the harvest was significantly earlier and quicker than average. In the Bay of Plenty, Gisborne, Hawke s Bay, Lower North Island and Taranaki, growing conditions were generally good although tended to be dry towards harvest. In the South Island the silage crops grew well but could have benefited from more heat during the heart of the growing season. 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. IMPACT and PAT s effectively test and deliver new commercial hybrids 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 Northland, through the Waikato, to the Lower North Island last season. Together, these trials funnel more local information into the product commercialisation decision making process. It allows products to bring proven, industryleading 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 below.

8 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 trials. Side-by-side trial data collected from at least 20 locations, over several, 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.

10 TRIAL RESULTS, SIDE-BY-SIDE COMPARISONS AND STATISTICAL SIGNIFICANCE Trial results In order to ensure accuracy in 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 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 and statistical significance In a side-by-side comparison, Hybrid A and Hybrid B 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 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 products the same or different for yield? MAIZE FOR SILAGE hybrid performance & positioning information 2014 Page 7

11 Interpretation of the t-test stars ( ) for hybrid side-by-side yield The table below presents a summary of the possible t-test outcomes. 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 the two hybrids based on the yield data. Yield superiority can only be concluded where one to three stars are present. P CONFIDENCE SCIENTIFIC LEVEL OF YIELD INTERPRETATION VALUE LEVEL DESIGNATION SIGNIFICANCE ADVANTAGE Very highly <0.001 >99.9% YES Product superiority for yield can be claimed. Can significant confidently plant a product providing no key agronomic <0.01 >99.0% Highly significant YES traits are limiting, and/or if a key trait advantage exists. <0.05 >95.0% Significant YES Check the trait ratings for any considerations. <0.10 >90.0% CA Commercially Acceptable >0.10 <90.0% Not significant NO YES Not a significant result, but may be regarded as commercially acceptable from which to base a decision. Product superiority for yield cannot be claimed. Ignore the yield comparison and refer primarily to trait ratings to select between the products. 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. 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, we cannot conclude there is a yield difference between the hybrids. This may have 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-byside and we take great care to base our product yield statements on the outcome.

14 regression analysis A regression analysis is used to describe the relationship between two sets of data. In the case of this publication it describes the relationship between the yields of two hybrids related to the average yield of all hybrids in a series of trials where the two hybrids have been grown together. The regression graph below is made up by a number of important components; The coefficient of determination (R 2 ). This represents the proportion of the data that is explained by the lines of best fit. The higher the R 2 the more confidence we may have in the lines of best fit. If the R 2 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 for all hybrids in the same trial. Y axis = yield (in kilograms of drymatter per hectare) which is the individual hybrid yield. Along each axis the yield levels are indicated. The yield of each hybrid is plotted against the trial average yield as a measure of environmental potential. Each triangle or square symbol indicates an individual trial yield. The hybrid regression line. The hybrid regression line characterises the expected yield performance of a given hybrid 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 s beyond the boundaries of data points plotted on the graph. The regression is only accurate over the range of available trial yields.
