In most cases, the breakage increases with a decrease in temperature. A conventional grain drill or air seeder that is capable of handling large seed without cracking is important. Field pea typically is seeded in a narrow row spacing of 6 to 12 inches. Like other crops, dry field pea yield can be estimated prior to harvest. blackeyed peas, crowders, field peas, cowpeas, or just peas. As a green manure crop, field pea returns approximately 25 lb/acre of nitrogen (N) to the soil. Lesions can develop on pods, which may result in the seed becoming infected. In fact, corn in the no-till plots showed a small numeric yield advantage in the longer rotations (1.3 to 1.8 bushels per acre), but it was not statistically significant. From a single harvest, green pod yields will range from 2,500 to 4,500 pounds per acre, while shelled green and dry pea yield will range from 1,200 to 2,000 pounds per acre. A desiccant may be used to enhance crop drying prior to combining. A well-established stand of seven to eight plants per square foot is critical for field pea to be competitive with weeds. Depending on the variety, you will need about 35 to 40 kg seeds per acre. Field pea in a green fallow system yielded 3,425 pounds per acre of biomass and 103 pounds per acre of accumulated nitrogen in above-ground biomass at the Carrington Aschochyta (Mycosphaerella) blight and bacterial blight are economically important diseases of field pea that are confused easily. The majority (more than 70 percent) of the dry pea produced in the U.S. is exported. However, Rhizoctonia and Pythium also can cause root rot, seedling damping-off and reduced emergence. The total amount of biomass produced depends upon the pea plant density, the timing of initiation of regrowth, soil moisture, rainfall and the date of a killing frost. Consult the NDSU Extension Service publication PP1704 for more information. Opportunities also exist to utilize just-harvested pea fields for a volunteer pea cover crop. Most growers will select among the semi leafless varieties that are more determinate in development. However, the number of seeds per pound differ for various varieties. Under most conditions, the use of inoculants will satisfy the nitrogen requirement of a field pea crop. Accuracy of yield estimates depends upon an adequate number of counts being taken so as to get a representative average of the paddock. To check for nodulation, carefully dig up a number of plants and gently clear the soil from the root mass. With a more diverse rotation, there was no yield benefit observed with tillage in this trial. Primary field pea market opportunities are for livestock feed, seed and human food. Figure 2. The allowable storage time for pea at select moisture contents and temperatures is shown in Table 1. Table 1 lists the fertilizer recommendations for Georgia. Planting field pea after mid-May means it more likely will mature during warm, dry weather favorable to disease development. We use gypsum to get calcium and sulfur into our fertilizer mix. Like other crops, dry field pea yield can be estimated prior to harvest. Severe infections of ascochyta will result in premature ripening, lodging and reduced yields. Splitting involves a mechanical process and results in separation of the two seed cotyledons. Federal grain standards have been established for whole and split field pea. At all temperature levels, seed coat breakage increases linearly with decreasing moisture content. When field pea has been grown in rotation for a few times in the same field, the need for inoculation is not as critical, compared with growing field pea for the first time in a field. Field pea seeding rate was 350,000 live seeds per acre and planting was performed using a 20-foot Crustbuster no-till box drill with a 7.5-inch row spacing.
