Abstract

The isolation of p-hydroxybenzoic acid from greenhouse soils may explain the unfavourable effects of these soils on ragi seedlings. At concentrations of 25 and 50 ppm this acid produced elongated light-green seedlings and 6 and 10% mortality, respectively. The apparent cause of the unfavourable effect of waste-land soils, however, was the presence of dihydroxy stearic acid. Above 15 ppm this acid produced stunted growth and leaf yellowing. The seedling mortality at 15 and 25 ppm was 5 and 16%
