Thunder Bay Agricultural Research Station, Thunder Bay (TBARS; www.tbars.net), is famous for bringing in something new every year to its development oriented research program. The diversity at TBARS this year is going to be quite exciting and more than usual.
New Crops that will be seen first time this year are oriental and yellow mustard, quinoa, perennial winter rye (variety Ace 1), perennial wheatgrass (variety Kerneza), Round Up Ready alfalfa (WL 319 HQ and WL 354 HQ), forage brassicas, new multi forage crops blends, two cold tolerant high N fixation clovers (Frosty Berseem and Fixation Balansa), forage peas and two new perennial forage crops from New Zealand (Chicory* and Tonic Plantain**).
New Crop Varieties include:
- Canola: L230 (Liberty), 5545 CL (Clearfield) and 6086 CR (Roundup Ready)
- Malting barley: AAC Connect, CDC Bow, CDC Fraser, CDC Kindersley, Lowe and OAC 21. The last one is actually a century old variety, but has again generated interest in bear making.
- Barley general purpose: Canmore
- Spring wheat: Easton and Furano (HRSW), SY Rown (CPSR), AAC Cameron VB, AAC Concord VB, AAC Jatharia, CDC Bradwell and SY 479 VB (CWRS), SY 087 (CWSP), and CDC Alloy, CDC Carbide, CDC Dynamic and CDC Precision (Durum).
- Milling Oat: CS Camden
- Oat (others): Blake, Noranda, OA 1395-1, OA 1367-3 and Richmond.
- Winter Rye: Bono.
- Winter wheat: AAC Wildfire.
- Grain corn: MZ 1340 BDR, MS 6902 R, LF 728 R and VT2P (all Roundup Ready; first three from Maizex and last one from Brett & Young).
- Flax: Prairie Sapphire.
- White beans: Lighthouse and Mist.
- Soybean (conventional/food purposes): OAC Brook
- Soybean RR: NSC Leroy RR2Y and NSC Starcity RR2X.
- Green Pea: AAC Royce
- Italian Ryegrass: Crusader (from New Zealand)
Nutrient Management/Soil amendments/other:
- Last year we got almost linear response to N in canola up to 180 kg N/ha. This year, therefore, we have added a higher rate of N (240 kg N/ha).
- We are comparing response of canola to sulphur at graded rates of 12, 24, 36 and 48 kg/ha from two sources (ammonium sulphate and gypsum) along with a no S treatment.
- In another interesting experiment, we are comparing seed row placed gypsum @ 150 kg/ha (=19.5 kg S/ha) in canola, barley and peas with ammonium sulphate at equal rate of S applied as pre-seeding broadcast/and incorporated in the soil. Residual effect of these crops/S treatments will be studied next year on spring wheat.
- In addition, we are studying the effect of gypsum @ 2.5, 5.0 and 7.5 MT/ha on Galega forage production and feed quality. Gypsum treatments will be compared with lime application at rates (2.14, 4.28 and 6.42 MT/ha) to equal calcium supply from gypsum. Residual effect of these treatments will be studied over 3-5 years, and
- An experiment to find out optimum row spacing and seed rate for Galega seed production.
This is as at writing time on June 1, 2017. If any other good idea comes to our minds, we will try that too and let you know. Stay Tuned!
- Crops/Varieties: CPRS: Canada Prairie Spring Red, CWRS: Canada Western Red Spring, and CWSP: Canada Western Special Purpose wheat. * http://www.ediblewildfood.com/chicory.aspx
- Soil Amendments: Gypsum and lime are both soil amendments and source of calcium. However, gypsum is neutral (doesn’t affect soil pH), whereas lime is alkaline and is used to ameliorate acidic soils. Gypsum (calcium sulphate) is also a source of readily available sulphur and when applied to the surface soil it can overcome soil crusting and make the top soil loose. Both gypsum and lime may contain some other nutrients in small amounts as impurities.
