The objective of this project was to standardize peanut varieties tested over all test locations in the Mississippi Peanut Variety Trials. The reason for this research is to conduct unbiased yield trials on all peanuts evaluated in the Mississippi variety trials to determine which particular varieties are best suited to the different environmental and geographic areas of the state. These results are determined by planting these peanut variety trials in those areas of the state where the soil type is suitable for peanut production and those areas where peanuts are commonly grown. Each variety is packaged and maintained in the same manner throughout the season, so to evaluate their yield potential when compared to other varieties within the same block of land, grown under the same conditions. There were nine peanut varieties that were evaluated for yield performance in the Mississippi State Peanut OVT's in 2014. These nine varieties were selected by MSU's Extension Peanut Specialist and planted in trials that were conducted at six sites within the state of Mississippi, under both irrigated and non-irrigated growing conditions. One of these peanut OVT sites was center pivot irrigated, as needed and the remaining five locations were grown under non-irrigated conditions.
All entries were planted in a randomized complete block design, consisting of four replications for each entry. Upon maturity, the plots were dug with a KMC 2-row peanut digger/inverter and then harvested with KMC 2-row peanut combine equipped with a bagging attachment. Plot • weights were converted to pounds per acre, following statistical analysis. The yields ranged from about 2100 lbs/ A to 6500 lbs/ A. Data from two locations was not published due to extreme deer predation of the plots, resulting in substantial variability and yields well below the average for those locations. The mean yield for four locations that were published, was a little over 4800 lbs/A. The results of this unbiased yield data will provide the producers of the state of Mississippi with valuable information to make decisions on varietal selections for future growing seasons. This will enable a person to choose from a list of potential different peanut varieties that might potentially be the best suited to their particular soil type or area of the state. Choosing the variety with the greatest yield potential could help to maximize a producer's yield potential for their farm; therefore, increasing their profits. In most cases, planting the most well-adapted varieties will make a substantial difference in yield and profitability on a farm. Therefore, thorough testing of multiple peanut varieties across several different environments and management practices are a requirement to aid the producer in the peanut variety selection process.
