winter and early spring, remove the 
animals in late March or early April. 
If the crop is not uniformly grazed, 
clip it. Removing uneven and exces- 
sive top growth at this time, which 
is about 6 weeks before full bloom 
normally occurs, assures more uniform 
flower and seed development. It also 
reduces weed growth. 
Using selective herbicides in late 
March or early April is recommended 
if there are many weeds or other crops 
that may produce seeds that will 
contaminate the white clover seed. 
lixis “better to use herbicides’ .early. 
in the season than to depend solely 
upon cleaning and processing after 
harvest. Consult your State agricul- 
tural experiment station for chemical 
weed control recommendations. 
Since white clover blooms over a 
long period, ripe seed and florets in 
full bloom occur on the same plant. 
Harvest the seed crop when the 
greatest number of seed heads are 
light brown in color. This condition 
usually occurs 25 to 30 days after full 
bloom. 
Cut the seed crop with a mower. 
Let it cure in the swath or in small 
windrows. During showery weather, 
the mowed crop cures better in swaths 
than in windrows. Windrowing is 
better during clear, warm weather 
because it reduces harvesting losses. 
Handle the cut crop as little as possi- 
ble; each handling causes shattering 
losses. 
Pick up the swathed or windrowed 
crops with a combine equipped with a 
pickup attachment. Operate the com- 
bine carefully to do a good harvesting 
job and to reduce harvesting losses. 
Travel at the correct rate of forward 
speed and properly adjust the concave 
and screens and the cylinder speed. 
For instructions, see your operator’s 
manual. 
Artificial drying or drying by 
spreading the seed thinly under cover 
improves the quality of the seed. If 
the seed is spread thinly under cover, 
turn it every few days until it is 
completely dry. Rough cleaning re- 
duces the time required for drying and 
improves quality. 
Defoliation of the seed crop is not a 
dependable practice.
