If climate and fruiting conditions are good or excellent, consider 7 to 9 lbs of foliar N in at least 5 gals total volume per acre. If applying with insecticide, add insecticide to water first, then add fertilizer, and continuously agitate mixture. Refer to pesticide label and consult manufacturer s technical representative for fertilizer and insecticide compatibility information. Under prolonged drouthy conditions, apply no more than three consecutive weekly foliar applications of N. Do not apply foliar N if leaves wilt by noon. Foliar applications perform best if made during the cooler part of the morning or evening.
Analysis indicates N deficiency.
Apply 30 lbs of N per acre to the soil and water in promptly unless N has been soil applied in the last week. K tests near the deficiency level. Be prepared to apply potash depending on future tests. Check to be sure that soil moisture is not limiting soil potassium uptake. If yield potential is at least 1 bales per acre, apply 60 lbs K 2 O per acre to the soil unless potash recommended in a previous period was applied.
