No recommendation
2.
Analyses suggest
fruit loss. Check for cause.
3.
Please enter date
of 1st bloom on the petiole information form as soon as 1st bloom occurs.
This date is a key factor that affects your recommendation.
4.
Analysis indicates
N deficiency. Apply 20 lbs of N per
acre to the soil. Also, if soil moisture
is not adequate, apply 7 to 9 lbs of foliar N in 5 to 10 gals total volume
per acre as follows. 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.
a.
7 lbs = 15 lbs of
46% N solid urea or 3.2 gals 23% N liquid urea
b.
9 lbs = 19.5 lbs
of 46% N solid urea or 4 gals 23% N liquid urea
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.

6.
Apply 0.2 lbs of
actual boron in 2 to 5 gals of solution per acre as soon as convenient to
do so. If applying with insecticide,
add insecticide to water first, and continuously agitate mixture. Refer to pesticide label and consult manufacturer’s
technical representative for fertilizer and insecticide compatibility information.
7.
If N was not applied
to the soil as recommended on your last report, apply it now, plus 7 to 9
lbs of N as urea to the foliage (see Recommendation 5). If soil N was applied as recommended on your
last printout, apply foliar N only.
8.
On the next information
card, please enter the pounds of N per acre applied on this field to date
this year. This affects early season
N recommendations.
9.
The fruiting rate
affects N, K, and B recommendations. Use fruiting rates table provided on back of sample information
card.
10.
Analysis indicates
P is low. Unless as much as 40 lbs
of P2O5 per acre was applied preplant or later, sidedress
a liquid N-P fertilizer containing 5-15 pounds of N and up to 50 pounds P2O5
per acre.
11.
N is low but not
strongly deficient. The next sample
period is very important.
12.
Analysis indicates
N deficiency. 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.
a.
7 lbs = 15 lbs of
46% N solid urea or 3.2 gals 23% N liquid urea
b.
9 lbs = 19.5 lbs
of 46% N solid urea or 4 gals 23% N liquid urea
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.
13.
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.
14.
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.
15.
If yield potential
is at least 1 ˝ bales per acre, apply 60 lbs K2O per acre to the
soil unless potash recommended in a previous period was applied. If soil moisture is suspected to limit potassium
uptake, consider foliar potassium as in Recommendation 18.
16.
Analysis indicate
water deficiency.
17.
Analysis indicates
possible sulfur deficiency. Watch
for yellowing deficiency symptoms in top leaves. See Extension fact sheet 2058.
18.
Possible K deficiency.
Consider application of 4 to 6 lbs of K2O in 5 gals of total
volume per acre each week for 3 weeks, using the following or equivalent:
a. 3.6 gals/A of 3-0-11 b. 4
gals/A of 10-0-10 c. 5 gals/A of 16-0-8. for cold-mixed solutions use 4 to 6 lbs K2O
in 10 gals of 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.
19.
N is very low.
Collect another sample immediately.
NOTE: The relationship between petiole nutrient levels
and yield gets weaker as the season progresses. Predicting the response to foliar nutrient
addition, especially after the fourth week of blooming, is difficult and will
vary according to boll load, insect control, soil moisture, weather, and time
remaining in the season.
