Abstract

Previous research studies have indicated that peanut cultivars Florigiant and NC6 have a maximum crop value when the Seed Hull Maturity Index (SHMI) is 3.0. This SHMI value may be used as a guideline by the peanut grower to help determine the time to dig his peanuts. In order to determine the sample size needed to determine the SHMI, we have measured the variance among SHMI values for individual plant samples within commercial fields of peanuts. The average variability found among SHMI values was 0.166 with a maximum variance of 0.276. Using this information it was determined that 17 plant samples from a field would be adequate for most situations. However, if a field appeared to present unusually variable conditions an increased sampling rate to a maximum of 28 plant samples might be desirable. A plant sample may have one to three plants because of the entwining of plants. Recommended procedures are presented for sampling the field, subsampling of bulked peanut fruits, and determining SHMI for actual farm situations.
