Three peanut seeds previously surface-sterilized
(hypochlorite solution at 1.5%) were sown in each pot and daily
watered. Two earliness-upright cultivars were used in this assay:
Senegal 55 437, a Spanish type developed by International Crops
Research Institute for the Semi-Arid-Tropics (ICRISAT), and BR 1, a
Valencia type developed by Brazilian Company of Agricultural
Research (EMBRAPA).
