Term
| the mutual relationship between legumes and Rhizobium bacteria |
|
Definition
-Bacteria provides plant with N and plant provides bacteria with nutrients
-If their environment is deficient in N, then they fix soil atmospheric N into the plant. C skeletons from photosynthesis provide structures for amino acids. |
|

Term
| a certain characteristic of grazing tolerant cultivars of alfalfa and why that is |
|
Definition
-Those that are grazing tolerant tend to be winter dormant
-Crown morphology is the reason |
|
|
Term
| why it may not be possible to develop winter active, grazing tolerant alfalfa in the South |
|
Definition
| because selection for grazing tolerance tends to make alfalfa winter dormant again |

| some details about forage chickory (Cichorium intybus) |
|
Definition
-Member of the sunflower family (Asteraceae)
-Perennial cool-season herb which originated in Central Europe but was developed for forage production in New Zealand.
-Pure stands in New Zealand pastures yielded up to 22,300 pounds of dry matter per acre with crude protein content between 18 and 22 percent (comparable to annual ryegrass) and 62 to 77 % IVDMD.
-Chicory is suited to well or moderately drained soils with a soil pH of 5.5 or greater
-If chicory is grown without a legume partner, 100 to 150 lbs (N)/Acre should be applied in split applications: 1/3 at green up in early spring, 1/3 in early summer and 1/3 in early fall
-At peak growth periods, chicory produced 73 pounds of forage per acre per day.
-Maximum life of chicory stands with good quality will be about five to seven years
-Chicory should be grazed heavily, leaving a stubble height of 11⁄2 to 2 inches, for short periods of time.
-Intense grazing should prevent plants from bolting, which will extend the vegetative state and forage productivity.
-A rest period of at least 25 to 30 days between grazings will allow chicory stand persistence and optimum performance. |

| some details about forage brassica |
|
Definition
-Brassica forages are high quality, high yielding, fast growing crops that are suitable for livestock grazing.
-Both tops (stems plus leaves) and roots (bulbs) can be grazed and are very nutritious.
-Brassicas are very high in crude protein and energy, but extremely low in fiber.
-Weight gains by feeder lambs have been 0.2 to 0.4 lbs/day and 1.5 to 2.0 lbs/day for stocker cattle.
-Brassicas may best fit an early to late fall grazing program |
