Foliar Fertilizer on Spring Dry Green Peas

Tom Hutchinson
with Ken Hart, Lewis/Idaho County Cooperative Extension

Objective

Evaluate yield impact of foliar fertilizers on spring dry green pea production.

Location: 6 miles west of Nezperce, Lewis County, ID
Annual precipitation: 22 inches
Previous crop: Winter wheat

Treatments

Check - no foliar
Treatment 1 - 2 oz. seaweed and 1 lb. 7-11-27 w/ chelated micronutrients per acre (Reward, provided by Wilkes Agricultural Products)
Treatment 2 - 7 lbs./acre 17-22-22 w/ boron, copper, manganese, molybdenum and zinc (Gainer, provided by the Lewiston Grain Growers)

Comments

Foliar application of 10 gallons solution/acre was made on May 25, 1995, with peas in first bloom. Plot size was 30' X 1100', with four replications. Plots were harvested on September 6 and weighed with portable truck scales. The field sustained 40% hail damage, which may have increased yield variability across the plot

Conclusion

Yield of peas was not affected by foliar applications, as measured by this test. This field suffered a 40% hail loss. The hail may have introduced additional yield variability in the plot. The lateness of the season and extremely wet and cool conditions may also have hampered the action of the foliar treatments.
