27 September 2021, UK: As another ‘out of the ordinary’ season draws to a close and the drilling of wheat crops commences, we share technical information on our varieties to help you position them on farm and establish a good crop, which starts with the seed. This season has tested variety resilience and really shown the true value of proven varieties that deliver on farm.
First and foremost, selecting a variety recommended for your chosen end-market is a good starting point. Syngenta have four hard group 4 varieties on the current Recommended List. Each has a unique agronomic profile and growth habit to address the different needs of UK feed wheat growers. Below are some of our top tips for selecting the right variety for your farm and how to get them off to the best start.
Regional yield and grain quality
Whilst UK yields give an interesting insight into a variety’s potential, regional performance is a good indicator for local suitability of varieties. SY INSITOR and GLEAM have no geographic limitations across the UK and are an excellent choice in all regions. SY INSITOR however, does perform particularly well in the North of England and Scotland. GRAHAM excels in the Western region, being the joint top yielding variety on the current Recommended List and showing strong performance again in trials this season.
Harvest 2021 has been challenging for specific weight and has demonstrated the importance of selecting varieties with inherently high grain quality to ensure contract specifications are met. SY INSITOR, GRAHAM and GLEAM all offer an ideal combination of high yield and good specific weight, which have all delivered above market standards this year, despite the challenging conditions.
Target drill date is another critical factor to consider when selecting a variety. In some scenarios, early September drilling remains both practical and effective – particularly where grass weed pressures and BYDV risks are minimal. For early drilling, we would recommend varieties that have robust disease profiles for primary diseases, (particularly Yellow rust and Septoria tritici), stiff straw and slow overwinter development to avoid excessive biomass and risk of frost damage to the ear in spring. GRAHAM is a particularly strong option for September drilling. GLEAM has an extremely wide drilling window, so if we are to endure another autumn like we had in 2019, GLEAM offers the flexibility with planting date and is an option which will perform whether drilled early or late.
Varieties with significant early spring vigour may be appealing if you are planning to drill slightly later due to workload, BYDV or grass weed pressures. SY INSITOR and SHABRAS fit extremely well here. Faster development and additional vigour in early spring makes these varieties well suited to delayed drilling and makes them more effective at competing with grass weeds.
