Dear UK & Irish Maize Grower, 

This book contains the results of the PACTS ® (Pioneer Accurate Crop Testing System) Maize Forage 

and Grain Trials conducted in the UK & Ireland between 2009 and 2012. 

Although 2012 was a challenging year for nearly every grower in our region 2013 is a new 

opportunity to exploit the unique benefits that maize possesses. Information for DuPont Pioneer 

hybrids and how they are likely to perform in the UK & Ireland is shown inside. In addition to 

the usual yield and quality results we also present, for the first time, information on the gas yield 

potential for each hybrid. 

PACTS ® Trial Performance Highlights 

P6862 – this extra early maturity hybrid was launched in 2012, specifically for those growers looking 

for high silage quality and the earliest possible harvesting dates. In 2012 P6862 continued to show 

that it is the earliest maturity hybrid in the Pioneer range. 

PR39V43 – Is a very early maturity hybrid that has now proven itself in six years of PACTS trials. In 

2012 PR39V43 once again produced high yields with consistent early maturity. It completed starch 

formation quickly making it suitable for producing both forage and dry grain or crimped maize. 

P7892 – Launched in 2012 this very early maturity, large stature, silage hybrid has again given very 

high yields. It has a strong package of agronomic features including very good early vigour and fast 

stover dry down. P7892 is likely to increase in popularity in 2013. 

P7524 – A new early silage hybrid for 2013. P7524 is a hybrid with a striking appearance, very tall 

with very good early vigour and high dry matter yields. It is ideally suited to growers looking to 

surpass their current silage dry matter yield levels and is likely to also find favour with those growing 

for biogas usage. 

P7905 – Another new Early maturity hybrid for 2013. P7905 has given very high yields of high 

quality silage in two years of PACTS trials, when grown either in the open or under film. P7905 

promises to raise the starch and dry matter yield performance bar for growers on favourable sites in 

the open and those planting using the Samco System. 

JUSTINA – Reliability and consistency has maintained JUSTINA’s position as one of the most popular 

maize hybrids of recent years. JUSTINA can rightly be called “The Great All-Rounder” because of its 

ability to cope with a wide range of field conditions to produce silage or grain. 

Pioneer ® Brand Inoculants 

The Pioneer range of proprietary silage inoculants for the UK & Irish farmer has a wider range of 

applications than ever before. 

The traditional products - PIONEER ® 1188, PIONEER ® 11G22 and PIONEER ® 11A44 - are now fully 

complemented by the new Fibre Technolgy product range including PIONEER ® 11GFT, PIONEER ® 

11CFT, PIONEER ® 11CH4 and PIONEER ® 11AFT.

Fibre Technology products all contain a unique strain of bacteria that produce an enzyme that 

breaks the bonds that hold lignin together. Silages treated with these new products have shown 

significantly improved levels of fibre digestibility.

PACTS Trials Background Information 

The purpose of PACTS Trials 

Whether a particular maize hybrid realises its full genetic potential depends largely upon 

how well it is adapted to the local environment and how successfully it is managed. 

The PACTS Trial Results are intended to help growers identify which Du Pont PIONEER 

hybrids are best suited to their location and circumstances, and additionally indicate 

agronomic techniques that may help maximise yields. 

Layout 

Each PACTS Trial is established within a commercial crop of maize and is planted and 

harvested by the host farmer with the assistance of Pioneer staff. All trials are managed 

as part of the field and the results are reflective therefore of the effect of local weather 

conditions and actual crop management practices. 

A PACTS trial is generally comprised of between 15 and 20 plots. The plots are planted 

in identically sized marked areas adjacent to each other across a uniform part of the 

selected field. Each plot is usually 6 or 8 rows wide and normally 50 metres in length. 

Typically every fourth strip is the same hybrid and is designated as a Control variety. The 

Control hybrid provides data that can be used to offset the misleading effect of soil type 

changes across a trial. In 2012 the Control hybrid was PR39V43. 

Sites 

Each trial site is classified as being Favourable or Less Favourable depending upon the 

heat accumulation that would be typically measured at that location. The results from 

individual trials are detailed in this book however due to space restrictions some trials 

are not shown. The results from trials not shown are available on request. All trials 

harvested are detailed in the Agronomy Details section of this book. 

Competitor Hybrids 

Typically four varieties from competitor plant breeding companies, which have been widely grown commercially in 

previous years, are included in each PACTS Trial. The competitor hybrids used in 2012 were Kaspian, Surprise, Kougar 

and Fabregas. 

Maize Hybrid Selection 

The selection of a particular hybrid for cultivation inevitably varies according to the different criteria a grower has. 

In many situations yield is of paramount importance but earliness of maturity is usually another critical factor. Other 

factors such as standing power, silage nutritional quality and end-use intentions e.g. whole plant silage fed to livestock 

or used for biogas production should be taken into account. No single hybrid will suit all situations. 

2

The following factors are just some of those that can have a major influence on the quantity, quality and value of the 

maize crop produced. 

The Environment Crop Husbandry Hybrid Genetics 

Latitude Seedbed Quality Yield Potential 

Soil Type Drilling Date Early Vigour 

Altitude Planting Population Disease Resistance 

Aspect Fertiliser Policy Maturity 

Shelter Use of The Samco System Standing Power 

Harvesting & Storage Use On-Farm Sell Off-Farm 

Harvesting Method As Feed Silage Quality 

Harvest Timing For Biogas Production Consistent Supply 

Storage Method Ration Supplementation Value versus Other Feeds 

Feed-Out Methods Ration Consistency Local Demand 

Use of Inoculant Yeast and Mould Content Transport Costs 

Growing a maize crop that meets all requirements depends upon selecting a hybrid with the most appropriate genetic 

potential and then managing that hybrid in a manner that will meet the chosen objectives.

Methane yield figures are determined using a calculation based on the Weissbach formula and actual yield and quality results from the UK & Ireland PACTS Trials. This formula predicts gas output based 

on the value of the key substrates in the forage prior to fermentation. The calculation of Fermentable Organic Dry Matter, or ‘FoTs’, is a key part of the formula and the FoTs is easily determined using 

standard laboratory results.

Growing Maize Under Film 

The Samco System was developed to provide dairy 

farmers in Ireland a more reliable way of cultivating 

forage maize. The Samco System provides extra heat 

during the first few weeks of growth when the plant is 

often challenged by cold temperatures. Over the course 

of the growing year the System significantly increases 

heat accumulation which either brings forward the 

harvest date or increases the yield depending upon the 

variety sown. 

Samco and Maizetech have worked closely with Pioneer 

for many years to understand exactly how different 

varieties behave when sown under film. This work has 

become increasingly important as the effect that some of 

the new Samco films have on the behaviour of different 

Pioneer varieties. 

Such effects have been shown to be particularly valuable 

in marginal areas or seasons with low amounts of 

accumulated heat. The thin plastic film creates a microclimate 

for the maize seeds as they germinate and grow. 

This micro-climate increases the crop’s ability to survive 

during periods of cold temperatures and frost compared 

to that of crops sown in the open. It has been shown in 

independent trials that the temperature of the air and 

soil underneath the film can rise rapidly after sowing, 

and early growth and establishment can be significantly 

advanced. 

Extensive trials and commercial experience have shown 

that certain maize hybrids are more suited to sowing 

under film than others. Some are clearly unsuitable. 

The Pioneer hybrids JUSTINA and BENICIA have 

been extensively grown under film with prominent 

commercial success and have become the backbone of 

the system. The main features of all the different Pioneer 

hybrids intended for cultivating with the Samco System 

are described below: 

P7892 

This very early maturing, high starch content hybrid 

is intended for Samco System growers on the most 

marginal sites located in the coolest areas of the region 

e.g. South West Scotland, Northern Ireland. 

P7631 

For growers in many areas of the UK & Ireland who are 

seeking an early harvest with a very high starch content 

silage. P7631 is between one and two weeks earlier 

to mature than JUSTINA and has shown very good 

resistance to Eyespot (Aureobasidium zeae). 

Independent research has demonstrated that The 

Samco System provides the potential for significant yield 

increases and/or earlier harvest dates in the maize crop. 

P7905 

This large stature hybrid is new for 2013. P7905 is 

slightly earlier to mature than JUSTINA but in trials so far 

19

Growing Maize Under Film 

has produced higher starch content silage and slightly 

higher dry matter yields. 

JUSTINA 

JUSTINA continues to provide benchmark yield and 

quality performance for any grower planting under the 

Samco System. It penetrates film easily and responds to 

the extra heat generated in the soil. JUSTINA is a dual 

purpose hybrid and can be grown for silage or grain. 

to selecting a suitable hybrid it is important that 

appropriate advice is sought on all the other appropriate 

crop management techniques relevant to this method of 

cultivation. 

PR39T83 

After 4 years of PACTS Trials over 29 locations PR39T83 

has proven itself to be a winner in terms of delivering 

higher dry matter yields from the Samco System. The 

tendency of this large stature hybrid to produce two even 

sized cobs is largely responsible for its yield success. 

PR39T83 is between one and two weeks later to mature 

than JUSTINA. 

P8261 

A large stature hybrid intended for producing grain 

and high starch silage crops. Over three years and 19 

locations of silage trials it has given a higher starch yield 

and dry matter yield than JUSTINA. 

PR39A98 

This tall, large stature hybrid has given high dry matter 

yields under film. It penetrates film very easily and is 

aimed at growers looking to maximise silage dry matter 

yields. PR39A98 is one to two weeks later to mature than 

JUSTINA. 

BENICIA 

BENICIA is renowned for its popularity with growers 

looking for a big return from their investment in the 

Samco System. BENICIA is a large stature hybrid that 

grows well in the UK & Ireland climate under film and 

can produce crops of silage or grain. BENICIA is two 

weeks later to mature than JUSTINA. 

PR38Y34 

PR38Y34 has given very high silage dry matter yields 

when grown under film. This tall hybrid is one week later 

to mature than BENICIA and is intended for planting on 

favourable sites where a later harvest is acceptable. 

Samuel J. Shine of Samco Agricultural 

Manufacturing Ltd 

‘A fundamental part of the Samco System is the use of 

maize hybrids that we know are suited for cultivation 

under film’ says Sam Shine of Samco. ‘Samco and 

Maizetech work closely with Pioneer and their PACTS 

Trials programme to identify hybrids that respond 

significantly to the conditions that exist under the film 

and learn how to manage them in the field. JUSTINA 

and BENICIA were the first Pioneer hybrids that we 

identified as being key ones for The Samco System. 

Now other hybrids such as PR39T83, P7631, P7905 

and PR39A98 have also shown a consistent ability to 

provide extra yield from the Samco System, even in 

years of low temperatures.’

Website: www.samco.ie 

The agronomic practices required for cultivating 

maize under film vary significantly to those normally 

adopted when cultivating maize in the open. In addition 

NOTE: All Pioneer PACTS variety plots planted under film in the UK & Ireland have been sown using the Samco 

System. The Samco System incorporates the use of a specific type of planter and also films tested and approved 

by Samco. It should not be assumed that the types of yield responses shown in this book will be obtained when 

using either a different make of planter and/or films that have not been tested and approved by Samco.
