Conclusions and Recommendations from the LUARS 2020

Conclusions and recommendations from the LUARS 2020 Research Presentation

Dr. Tarlok Singh Sahota CCA

The following brief information could be useful to our producers who may not have time to read
lengthy reports:
 We had a very hot and dry June and July in 2020 which impacted the crops’ growth and
yield; except that of soybean and edible beans!
 AAC Wheatland and AAC Starbuck (Spring Wheat) could be recommended for
cultivation in 2021!
 Synasolis/and Boroe (Spring Barley) gave the highest grain yields!
 AB Brewnet is a new promising Malting Barley variety!
 CDC Bow’s (best over 2017-’20) grain and straw yields declined over the years!
 CDC Arborg and AAC Rigodon were high yielding Oat varieties!
 Even though Keldin and Gallus (Winter Wheat) gave better grain yields than AAC
Gateway, these can’t be recommended because they are often prone to winter kill!
 Late (mid Sep) seeded Winter Wheat could be a promising addition to cropping systems!
 Edible Beans (AAC Scotty) could be added to the crop rotations!
 Bourke R2X which has some disease resistance was the top yielding Soybean variety!
 Field Peas were eaten by deer and geese!
 Lentils and Linseed Flax had very poor yields (hot and dry weather)!
 L252, L241C and L230 were the top yielding Liberty Canola varieties!
 5545CL was the other top yielding Clearfield Canola variety in 2020!
 Winter Canola has failed to winter survive (past two years)!
 AC200 was the highest yielding Mustard variety!
 Galega had higher yield and protein content than Alfalfa (2012-’20)!
 Urea + ESN at 105 kg N/ha produced the best yield for Malting Barley! Sulphur had no
effect on Malting Barley yield!
 Urea + ESN @ 80 kg N/ha produced the best grain yield in Wheat!
 Hazlet and Guttino were the best Winter Rye varieties; use 100% recommended seed and
fertilizer rates!
 NK21 and Urea + MOP (0-0-60) gave similar grain yields of soybeans!
 Lentils could be grown without addition of N, P, K and S!
 It pays to use multiple sources of N (urea, ammonium sulphate and ESN) as compared to
urea alone!
 Seed yield in canola with urea + ESN @ 180 kg N/ha equaled that from urea alone @
270 kg N/ha!
 Gypsum or ammonium sulphate applied to barley, canola and peas had no residual effect
on grain or straw yield of wheat in the next year!
 September 15 is the optimum time to seed Winter Rye!
 There was no residual effect of Winter Rye (at different seed/or fertilizer rates) cover
cropping on Canola seed yield!
 Kernza could be grown in mixture with alfalfa!
