Lespedeza
Lespedeza
• Has broad, heart-shaped leaflets that are distinctly veined,
while common and Kobe leaves are longer and less rounded on
the ends.
• The few small hairs on the stems of the Korean varieties slant
upward in contrast to those on common or Kobe.
• Flowers of both species range from purple to light pink.
• After flowering, leaves of Korean turn forward around the seed
pod, which helps reduce seed shattering.
• Leaves of the common type do not fold around the seed pod,
so they are more susceptible to shattering.
• The seeds of Korean lespedeza grow in clusters at the terminal
end of each branch, while seeds of common lespedeza are set
in leaf axils along the entire length of the stem.
Chufa
Chufa
• Plant:
• Weed with a triangular stem and long, grasslike leaves.
• The mature plant will have a bloom that extends
upward from a ring outward-extending of
leaves.
• The bloom will have a furry texture.
Rye
grass
Rye grass
• Plant Description
• Annual ryegrass is a bunch-type grass that tillers profusely.
• The plant appears shiny, dark green and grows to a height of 2
to 5 feet.
• It has a deeply fibrous root system, erect culms, glabrous
leaves and a spike-type inflorescence.
• The inflorescence is composed of about 35-40 sessile spikelets
arranged alternately, with 10-20 fertile florets per spikelet.
• Awns are usually present and attached to the lemma.
• While annual ryegrass is generally considered to be an annual
specie, it has on occasion behaved as a short-term perennial or
biennial.
• It does exhibit a response to day-length, and flowering habit
varies with variety and latitude. Vernalization (cold treatment) is
not required for normal growth or for seed production of
adapted cultivars.
Turnip
Turnip
• The most common type of turnip is mostly white-skinned apart
from the upper 1–6 centimeters, which protrude above the
ground and are purple, red, or greenish wherever sunlight has
fallen.
• This above-ground part develops from stem tissue, but is fused
with the root.
• The interior flesh is entirely white.
• The entire root is roughly conical, but can be occasionally
tomato-shaped, about 5–20 centimeters in diameter, and lacks
side roots.
• The taproot (the normal root below the swollen storage root) is
thin and 10 centimeters or more in length; it is trimmed off
before marketing.
• The leaves grow directly from the above-ground shoulder of the
root, with little or no visible crown or neck
Soybean
Soybean
• The pods, stems, and leaves are covered with
fine brown or gray hairs.
• The leaves are trifoliolate, having 3 to 4 leaflets
per leaf, and the leaflets are 6–15 cm (2.4–
5.9 in) long and 2–7 cm (0.79–2.8 in) broad.
• The leaves fall before the seeds are mature.
• The inconspicuous, self-fertile flowers are borne
in the axil of the leaf and are white, pink or
purple.
Clover
Clover
• hairy surface underneath the leaf--sometimes they're
hairy on top as well--and a distinctive white "V" marking
on the top of each leaf segment. The white "V" is your
best way of identifying what you're looking at as red
clover, especially if it hasn't yet flowered.
• tend to sprawl but on occasion may grow over a foot
high, with leaves that consist of three ovals at the end of
a stem. Three-part red clover leaves look much like the
spades symbol you'll find in a deck of playing cards and
may on occasion grow to be well over an inch across
from one segment to another.
Corn
Corn
• Dent Corn is softer than Indian corn, but harder than flour corn. The
kernels have a hard case on them, about as thick as our fingernails,
but in the middle is a large starchy endosperm. The kernels develop
a dent as the kernel dries: the inside part shrinks but the outside part
doesn't, so it develops a dent. This won't be apparent when it's still
fresh on the cob.
•
The kernels are yellow or white. Dent Corn is by far the most grown
cultivar of corn. When you see a corn field, chances are it's Dent
Corn. There are many sub-varieties of Dent Corn today.
Wheat
Wheat
• Wheat is a cereal crop and was developed in prehistoric
times from grasses growing in the Middle East. Wheat is
an annual plant with fibrous roots and roots with spikes
of flowers. Each spike has two rows of spikelets, and
each spikelet carries one to six florets.
• Varieties of wheat include Duram, used to make
spaghetti, and Rivet, with a stiff straw, ideal for thatching.
When wheat is young, it looks like grass. The wheat is a
greeny colour, but turns golden when it is ripe. Wheat
can grow up to 5 ft high. The head of wheat can contain
up to 50 to 80 kernels.
Peanuts
Peanuts
• The peanut is a tender annual belonging
to the pea family. It grows 6 inches to 2
feet tall, depending on type. The bunch
type grows upright; the runner type
spreads out over the ground. Small
clusters of yellow, sweet pea-like flowers
grow on stems called pegs. The pegs
grow down and push into the soil, and the
nuts develop 1 to 3 inches under ground
from the pegs.
Oat
Oat
• Common Oat, has a smooth stem, growing up to 4 feet high,
with linear lanceolate, veined rough leaves; loose striate
sheaves; stipules lacerate; panicle equal, loose; spikelets
pedunculate, pendulous, twoflowered, both perfect, lower one
mostly awned; paleae cartilaginous, embracing the caryopsis;
root fibrous, annual.
• The Naked or Pilcorn Oat differs slightly from the other: calyces
three-flowered, receptacle exceeding the calyx; petals awned at
the back; the third floscule awnless; and the chief difference lies
in the grains, which when ripe quit the husk and fall naked.
• The grains as found in commerce are enclosed in their pales
and these grains divested of their paleae are used for medicinal
and dietary purposes; the grains when separated from their
integuments are termed groats, and these when crushed are
called Embden groats.
• Oatmeal is ground grain.
Cowpeas
Cowpeas
• All cultivated cowpea varieties are considered warm
season and adapted to heat and drought conditions.
• Cowpeas typically reach a canopy height of 30 to 36
inches, although the more determinate bush types
may reach only 24 inches.
• The seed pods are borne above the leaf axil, making
the pods very visible.
• The seed pod is typically 3 to 6 inches long and has 6
to 13 seeds per pod.
• The seed weight per bushel is 60 pounds with about
3,000 to 4,000 seeds per pound.
Bahia Grass
Bahia Grass
• This grass is low-growing and creeping with stolons
and stout, scaly rhizomes.
• Stolons are pressed firmly to the ground, have short
internodes, and root freely from the nodes forming a
dense sod.
• The flat, tough-textured leaves are usually hairless,
with blades 2-6 mm wide.
• They are flat, folded, and inrolled, tapering to a fine
point.
• The leaf bases at the terminus of each rhizome
usually have a purplish hue.
• Stems usually reach 20-75 cm tall.

The Austrian winter pea is a low growing vine annual legume.
It is sometimes called a black pea or field pea. It has a hollow, slender, succulent
stem that is 2-4 ft. long.
The Austrian winter pea pods have 3-5 round dark seeds that are commonly mottled
with purple or brown spots.
The foliage is pale green and the flowers are purple, pink or reddish.
The pea seed must be inoculated with the Rhizobium bacteria prior to planting.
This helps produce nodules for nitrogen fixation.
Austrian winter pea is generally a fall seeded cover crop that can be used for
grazing, hay or as a green manure.
The peas are seeded in September to October.
However, if exposed to long periods of sub-zero weather without snow cover, there
may be winterkill of the stand.
It can also be grown as a spring seeded summer annual sown as early as possible in
the spring.
Austrian winter pea has good nitrogen fixing capabilities and fits into a rotation from
wheat to sorghum.
There is a small market for Austrian winter peas as an ingredient in birdseed.
