The Effects of Potassium and Chloride Nutrition on Seed Yield of Canaryseed

The effects of potassium and chloride nutrition on seed yield of canary seed, was conducted to determine the responsiveness of canary seed to K and Cl- and provide better recommendations to producers on the use of potassium chloride (KCl) in canary seed production. The project had five sites each year for three years of field research.

Methodology


The following experiment will be conducted from 2007 through 2009:
    Fields will be selected with various levels of K and Cl at three locations, representative of the major canaryseed growing areas of Canada.

Locations:
    Indian Head, Swift Current, and Melfort, SK

Fields:
    1. 2 fields Deficient in K and Cl as rated by soil test (this will vary depending on finding suitable fields)
    2. 2 fields Marginal in K and Cl as rated by soil test (this will vary depending on finding suitable fields)

Treatments per field
    1. no K or Cl
    2. 15 kg K ha-1 (+ 13.7 kg Cl ha-1) as KCl
    3. 30 kg K ha-1 (+ 27.4 kg Cl ha-1) as KCl
    4. 45 kg K ha-1(+ 41.1 kg Cl ha-1) as KCl
    5. 15 kg K ha-1 as K2 SO 4
    6. 30 kg K ha-1 as K2 SO 4
    7. 45 kg K ha-1 as K2 SO 4
    8. 13.7 kg Cl ha-1 as calcium chloride (CaCl2)
    9. 27.4 kg Cl ha-1 as calcium chloride (CaCl2)
    10. 41.1 kg Cl ha-1 as calcium chloride (CaCl2)
    Blanket application of fertilizers on all plots at a rate of 100 kg of 46-0-0 (urea), 50 kg of 11-51-0 (mono ammonium phosphate) and 50 kg of 21-0-0-24 (ammonium sulphate) ha-1. Preference will be given to seeding on broad leaf stubble.

Data Collection:
    - Soil test N, P, K, S and Cl, texture, organic matter content, pH, EC.
    - Plant density.
    - Monitor leaf diseases, and rating and control if required.
    - Monitor aphids, and control if required.
    - Monitor lodging, and rating if required.
    - Number of heads/m2.
    - Seed yield.
    - Kernel weight.
    - Test weight.
