The occurrence of boron deficiencies in Spanish peanuts ( Arachis Hypogea L.) is Inconsistent in an environment as variable as that found in Oklahoma. A foliar analysis is needed to identify a boron deficiency potential in Spanish peanuts. The use of a foliar analysis requires a knowledge of the uptake and distribution pattern of the nutrient in question to assure proper sampling technique and correct interpretations. This study was conducted to determine the uptake and distribution patterns of boron in Spanish peanuts. A greenhouse experiment with Eufaula loamy fine sand and three field experiments on Yahola loamy very fine sand, Norfolk loamy fine sand, and Durant loam were conducted to determine the distribution pattern of boron in the leaves and petioles of Spanish peanuts. Soil applications of O, 0.25, 0.50, and 1.00 ppm boron were applied to greenhouse pots containing 4,000 g of soil. Zero and 1.1 kg/ha of boron were applied to two field plots and O, 0.6, and 1.1 kg/ha of boron were applied to the third field plot. Leaflets and petioles were collected from varied parts of the peanut plant over a period of 70 days in the greenhouse and from July 16 through October 4 in the field. The boron concentrations in the leaflets and petioles were significantly higher (5% level) from plants grown in the boron‐treated soil. The youngest petioles and leaflets reflected the most recent status of soil boron availability and were considered to be the desired foliar material for identifying boron deficiencies in Spanish peanuts by plant analysis.
