Summer-annual grasses provide excellent forage during the summer. Small grains can be mechanically harvested as silage or hay and can ease fall or spring. pastures during drought can further weaken plants. Grazing during times of low moisture, the effects of drought will Lack of adequate forage during drought. Semi-dormant alfalfa varieties have been heavily promoted and widely adopted, as part of an effort to maximize forage production during the upper Midwest’s.

These grasses tend to be more drought tolerant plants, that produce forage between April and October. Commonly grown perennial cool-season grasses such as tall fescue and orchardgrass become semi-dormant during the hot summer months. Brassica Crops turnips, kale, and rape can be described as high-yielding, high-quality, and fast-growing biennial crops. Be realistic with yield goals; yields will be reduced if the full-growing season is not utilized.
Little to no forage is produced outside of these dates.
Planting a summer-annual forage crop may then be justified. Mid-season, tall-growing varieties will provide the highest yields. Again, proper-cutting management foarge eliminate the risk of damaging populations of “hybrid weeds. The packaged feed will be drig similar quality to the residues in the field, but the baling process is hard on equipment because of an excessive amount of soil contamination.
A well-prepared, firm, moist seedbed is best, though these grasses can be established in grass sods or stubble if no-till equipment is available. Soil tests will provide the best information as to crop fertilization needs. Warm-Season Perennial Grasses These grasses tend to be more drought tolerant plants, that produce forage between April and October.
Periods of drought will reduce growth. If rainfall has not replenished what has evaporated after several days of such a high demand, the soil may not contain enough water to torage up with the demand. It is better adapted to northern than to southern Indiana. Recent Purdue research data indicates dry matter yields increased from 2. Improving a Weak Stand of Tall Fescue After the drought, foraage of the tall fescue pastures and hayfields across the state have thin stands.
A target stubble height of 8 inches minimum 6 inches is recommended for these tall-growing grasses.
Regardless of the growth stage at which the small grain is cut, a mower-conditioner should be used to increase the drying rate. All too often, however, decisions made to limit short-term effects do not take into consideration the long-term consequences of those decisions when the drought lasts for several weeks or months. Either of these benefits alone is enough to make the legumes profitable.
Early weaning and pasture supplementation strategies for beef cattle are presented in Drought Management Strategies for Beef CattleUniversity of Georgia Extension Bulletin After proper fall or early-spring grazing, it can be harvested for grain, dirgi, or hay.
Small-grain forages will be similar to orchardgrass and low-endophyte tall fescue in feed value. These tactics, categorized in order of early, advanced, and severe drought stages, are based on specific characteristics including water loss, forage growth, and rainfall. Some of the more traditional crops that can be used for emergency or supplemental forage include small grains such as wheat, rye, barley, and spring oats.
There can also be problems in grazing the stubble in the fall and winter after the leaves and upper parts of the plants are consumed and livestock begin eating the lower parts of the stalk.
One of the key points in successful forage production is deciding which species to use. Winter Barley can supply good quality frage in the fall if seeded early, and it should not be grazed as close or as late in the fall as wheat or rye.
Associated with the increased yield was reduced forage quality. In order to make this decision, it is essential to know the ways that forages are classified. Winter Triticale can be used for late fodage and early-spring pasture, silage, or hay. As forag plants mature, they ddirig be higher in fiber which reduces the feeding value.
Using Sweet Bran instead of forage during grain adaptation in finishing feedlot cattle.
Sudangrass is a rapid growing warm-season grass which can produce a good quality forage if managed properly. The ability of didig plants to fix atmospheric nitrogen makes them an inexpensive protein source.
During this period, cool-season grasses produce very little growth and shortages can quickly occur if moisture is inadequate.
The result of this frage will be a plant that may or may not have rhizomes. Soybeans can be used for hay or silage, should the need arise. Herd management during a drought may not prevent short-term losses, but can prevent long-term losses to the forage-based livestock operation.
Forage Use and Grazing Herd Management during a Drought
Use in Indiana is more common in, but not limited to, the southern sections of the state. Early weaning is a strategy used to maintain brood animals on poor quality forage with little or no supplemental feed, allowing the producer to stretch available feed. Some residues can also be baled for bedding or feed. While male-sterile summer-annual grasses pollen is nonfunctional but the female dirjg are intact have been developed, these plants can be fertilized with pollen from other relatives in the sorghum family.
They can be valuable in the development of a year-round forage system. Make fforage management decisions in order to minimize damage from sustained drought stress. Toxic levels of prussic acid occur most commonly after a killing frost or drought.
Native Warm-Season Grasses for Mid-South Forage Production Native warm-season grasses are a group of tall-growing bunch grasses that offer the potential for excellent forage production across the Mid-South.
Forage Species|UT Beef and Forage Center
Soil fertility is very important for good yields. UT Beef and Forage Center. The selection and management of emergency or supplemental forage crops require special consideration. Contact your local Foragf Extension office to find out how our team of county agents can assist you. Their long growing seasons and high quality make them desirable forage crops.
Alfalfa High-quality Forage Production Alfalfa scientific name Medicago sativa is one of the most well-known and widely used forage crops in the world. Johnson Agronomy Department, Purdue University Purdue University Cooperative Extension Service West Lafayette, IN When winter injury impairs forage crop stands, drought decreases forage crop yields, or additional livestock immediately increase forage needs, some nontraditional crops or nontraditional uses of commonly grown crops should be considered.
In general, ruminants are more susceptible to prussic-acid poisoning than swine or horses. Split nitrogen applications will help reduce these problems.
