Two Valencia peanut (Arachis hypogaea L.) cultivars, New Mexico Valencia A and New Mexico Valencia C, were grown at Arch and Los Lunas, N. M. All peanuts were grown under either sprinkler or furrow irrigation. Samples were obtained following harvest, hydrolyzed and analyzed in Raleigh, N. C. for amino acid content. With samples from Arch, no variety by planting date effects were noted for amino acid composition. With samples from Los Lunas, however, significant variety by planting date effects were noted for glutamic acid, glycine, methionine, isoleucine, and leucine. Planting date effects were found only for glycine at the Los Lunas location and phenylalanine at both locations. Significant variety differences were found for methionine, tyrosine, phenylalanine, and lysine at the Arch location and for glycine, methionine, phenylalanine, and lysine at the Los Lunas location. A significant year effect, although small, was noted for about half of the amino acids (aspartic acid, serine, glutamic acid, proline, glycine, tyrosine, phenylalanine, arginine, and the sum of all amino acids) studied at the Arch location. Data at Los Lunas were observed only during the second year. The amino acid content agrees closely with that previously reported for other types of peanuts except for a 100% higher level of cystine found in this study.
