Yield & Grain Quality Of Scottish Landrace Of Barley (Bere) Affected By Nitrogen, Plant Growth Regulator & Fungicide In Orkney [Syed Shah]

  1. 1. Yield and grain quality of Scottish landrace of barley (Bere) affected by nitrogen, plant growth regulator and fungicide in Orkney By : Syed Suhail M. Shah PhD 3nd Year Supervisor (s) Dr. Xianmin Chang (Agronomy Institute, Orkney College) Dr. Peter Martin (Agronomy Institute, Orkney College) Dr. James Chalmers (Orkney College) Prof. David Robinson (UOA) Dr. Barry Thornton (Macaulay Institute)
  2. 2. Outline • Bere • Production constraints • PhD trials – Results • Summary • Any question?
  3. 3. Bere • Is a landrace of barley • It is unique in the UK – For bannocks – Bread and biscuits – Beer and Whisky • What is a landrace? • Why landraces?
  4. 4. Production constraints • Lodging • Foliar diseases • Low grain yield (2.8-3.8 t ha-1 ) compared with (6.0-8.0 t ha-1 ) of modern varieties • Low spirit yield (351 l ha-1 vs 410 l ha-1 ) due to higher grain nitrogen content.
  5. 5. PhD research project • Research Question: – How does Bere differ from modern variety • Management strategies to achieve – High yield – Grain quality • The main focus was to investigate the effects of – Nitrogen fertilizer – Fungicide – Plant growth regulator

  16. 16. Summary and conclusion • Bere has a better yield stability than Optic • Responded reasonably to inputs, however, yield gains are lower than modern variety (s) • Has inherently higher nitrogen content due to which it is highly unlikely that a large area will be grown with Bere • Its survival is based on the existence of traditional market in Orkney • It is important to develop niche markets and specialist products such as Bere whisky and Island Bere (beer) • Bere is a low risk option under lower input system and may be suitable for organic farming which needs further study
