Foliar Fertilizer on Lentils

Darrel Uhlorn
with Ken Hart, Lewis/Idaho County Cooperative Extension

Objective

Evaluate yield impact of foliar fertilizers on lentil production.

Location: Ferdinand, ID
Annual precipitation: 22 inches
Previous crop: Winter wheat

Treatments

Check - no foliar
Foliar Treatment 1at 2.75 qt./acre 7-27-7 with magnesium, iron, zinc, copper and organic and amino acids (Lucky 7, provided by Lewiston Grain Growers)
Foliar Treatment 2 - 7.5 lb./acre 15-20-20-2 w/ boron, copper, manganese, molybdenum, and zinc (S & A High Yield, provided by Union Warehouse)

Comments

Foliar application of 10 gallons solution/acre was made on July 3, 1995, with lentils just showing signs of first bloom. Plot size was 30' X 1100', with four replications. Plots were harvested on September 22 and weighed with portable truck scales. The field sustained 33% hail damage, which may have increased yield variability across the plot.

Conclusion

Yield of lentils was not affected by foliar applications, as measured by this test. The 33% hail damage 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.
