11. WITHIN CLIP AREA: Make clippings in the designated ROW within Clip Area OF EACH unit following steps below.
If Unit 2 Maturity Code is 2, enter enumerator and supervisor numbers below and sign name.
Discard Unit 1 clipping and DO NOT send any clippings to the lab.
Step 1 -- Mark half-way point in specified row in clip area.
Step 2 -- MOW (cut stalk within 2 inches of base) all wheat stalks in specified row until 5 emerged heads (if that many) are
obtained OR until one-half the row is completely mowed. Begin mowing at the end of the row farthest from count area and
mow in direction of count area. Examine each stalk for emerged head as it is mowed; if present, clip stalk 1/2 inch below the
head. Place the 5 (or less) emerged heads in a small bag. Record count on YELLOW I.D. tag. Also, when mowing, clip and
count any heads in late boot at base of top foliage leaf and place in a medium size bag
Step 3 -- MOW remaining stalks up to the half-way mark. Examine each stalk and determine which ones are emerged heads
and late boot heads. CLIP the stalks 1/2 inch below the emerged head or at base of top foliage leaf for late boot heads. Place
the remaining emerged heads in a large bag and the late boot heads in a medium bag.
Step 4 -- Record the count of the remaining emerged heads and the late boot heads on the YELLOW I.D. tag.
Repeat steps 1 through 4 for Unit 2 using same bags for emerged heads and late boot heads as used in Unit 1.
Prepare one I.D. tag. Label all bags with sample number. Seal and place the small and medium size bags in the
large bag. Seal large bag. Verify and date YELLOW I.D. tag and attach to outside of large bag using one rubber band.
Check here

supervisor numbers and sign name.
12. WITHIN COUNT AREAS -- Clip and Count all heads in count area of BOTH units following steps below.
Use a separate large bag for each unit.
Step 1 -- Clip all heads in Late Boot at base of top foliage leaf in Row 1 - Compare with item 8 count
Step 2 -- Clip all Emerged heads 1/2 inch below head in Row 1 - Compare with item 9a count and place emerged heads in
same bag with late boot heads.
Step 3 -- Repeat steps 1 and 2 for Rows 2 and 3. -- Check counts.
Step 4 -- Pick up all Detached Heads on ground in unit counted in item 9b. Place in bag with clipped heads.
Copy recorded heads from items 8 and 9 of Form B onto PINK I.D. Tags. Date and attach one Pink I.D. Tag to each large bag .
