Bayer Arize
A mid season, long grain hybrid with good yeild potential and is moderatly resistant to sheath blight.
Catahoula
A semi dwarf, long-grain with good yeild and milling potential and resistant to blast.
Cheniere
A very short season, semi-dwarf, long-grain rice variety with good yeild potential that has similar height and lodging resistance as cocodrie but is less suceptible to straighthead.
CL131
A midseason, semi-dwarf long- grain similar to CL161 with shorter plant height, moderatly susceptible to blast, very susceptible to straighthead and sheath blight, but improved grain yeild potential.
CL151
A midseason, semi-dwarf long-grain similar to Cocodrie with good yeild potential and high tolerance to Newpath herbicide. It is very susceptible to blast, straighthead, and susceptible to lodging and sheath blight.
CL161
A midseason, semi-dwarf, long-grain similar to Cypress with high tolerance to Newpath herbicide. It is very susceptible to sheath blight, susceptible to blast and moderately susceptible to straighthead.
CL171 AR
A midseason, semi-dwarf, long-grain similar to Wells with high tolerance to Newpath herbicide. It is susceptible to sheath blight, moderately susceptible to blast and straighthead. Yield is similar to CL 161.
FRANCIS
A very short season, long-grain with excellent yield potential, susceptible to rice blast and very susceptible to kernel smut. It is the best long grain for high pH and salt soils of NE Arkansas west of Crowley’s ridge but should not be stressed for water due to blast concerns.
JUPITER
A high yielding, semi-dwarf medium grain variety developed by LSU. Jupiter has a good disease package, displaying good resistance to blast, panicle blight, sheath blight, and straighthead. It has shown good seedling vigor and milling quality. The grain size of Jupiter is somewhat smaller than Bengal.
Neptune
A high yeilding semidwarf medium grain that has productivity similar to jupiter. Neptune has a very good disease resistance package with good tolerance to most major rice diseases.
Templeton
A new midseason, high yeilding, long grain cultivar with resistance to the common blast races in arkansas. Templeton has good milling yeild and high yeild potential. It is moderatly susceptible to sheath blight and very susceptible to straighthead.
WELLS
A short season, long grain with excellent yield potential, average to good milling quality, large kernel size similar to Lemont, but is susceptible to rice blast. Only moderately susceptible to kernel smut and most other diseases and is the most widely adapted long grain rice in Arkansas.
COCODRIE
A short season semi-dwarf long-grain with good yield potential and milling quality. Susceptible to sheath blight and other diseases. High bran oil content makes it somewhat of a milling concern to certain buyers.
Rice Seed Production
Rice seed is planted by only the top seed growers in our area. Production fields are monitored throughout the growing season by our Agronomist and Seed Certification Manager for off-types, red rice, and other noxious weeds. As a general rule, all certified seed is rogued 3 times and all registered seed fields are rogued 4 times.
CRVS Conditioning Process
Step 1: The seed is conditioned using a Cimbria Delta 108 Seed Cleaner.
Step 2: After the cleaner, the seed is then processed over and LMC Gravity Table.
Step 3: Our rice seed is then run through Carter Disc Machines to remove cracked seed.
Step 4: Long grain rice is then run through a precision grader to insure against medium grain, off-types and red rice.
Seed Treatments
Cache River Valley Seed offers funigicide seed treatments such as Dynasty, Apron and Maxim to protect the yield potential of the seed after it is planted. Giberellic acid (Release) and zinc seed treatments are also offered.
Packaging
Cleaned rice seed is packaged in 50 lb. paper bags, 2025 lb. (45 bushel) bulk bags, and stored in bulk bins. Sorting rice in bulk bags allows us to keep more cleaned seed on hand for faster load out time.
Final Certification
The Arkansas State Plant Board pulls a 4 pound sample from each lot and checks for germination and purity. NO RED RICE can be found in this sample in order for it to make Arkansas Certified quality.
Did You Know?
If your rice seed contains 1 red rice in a 4 pound sample, planted at a rate of 3 bushels per acre, you would plant over 33 grains of red rice per acre. Each grain could produce 12 tillers per plant @ 150 per head for a total of approximately 59,400 seeds per acre in the first year and over two million per acre in the second year.
The Arkansas State Plant Board has found that less than 1% of all cleaned certified rice samples contain barnyard grass but that 50% of all rough samples are found to contain barnyard grass.
Arkansas requires a 4 pound sample for each lot of cleaned seed. The state of Mississippi only requires a 1 pound sample for testing. This means that Arkansas has 4 times as much rice which could be milled and checked for red rice and off-types.
All seed rice for sale, both rough and cleaned seed, must have a complete analysis that includes a purity and germination.
