The nutrient contents of peanuts (Arachis hypogaea L.) grown under nutrient‐sufficient conditions were determined in relation to yields of lines derived from 15 cultivars. Four plant portions of the lines, each a single seed selection, representing four market types were analyzed for contents of eight nutrients.
In general, the fruit was highest in P and Zn contents and lowest of the four portions in K, Ca, Mg, B, Mn, and Cu contents. The upper central stem leaves were highest in Ca, Mg, Mn, and B contents and intermediate in P, K, Zn, and Cu contents. The first lateral branch leaves were highest in K content, intermediate in P, Ca, Mg, B, and Cu contents and lower in Zn content than the above portions. Copper content was highest and P content lowest in the hypocotyl whereas the other nutrient contents in this portion were generally higher than in the fruit portion only.
Lines of the large‐seeded Virginia type were generally highest in K, Ca, and B contents, intermediate in Mg content, and lowest in P content of the four types. The small‐seeded Virginia type lines were highest in Mg content, equivalent in Cu and Mn content to the large‐seeded lines, and intermediate in P and K contents. The Spanish and Valencia lines were highest in P content, lowest in Cu content, but equivalent to the small‐seeded Virginia lines in K, Ca, B and Mn contents.
