Trials were carried out to test the effects of Atonik 1:2000 (sodium mono-nitroguaicol and other aromatic nitro compounds) on fruiting of chillies and three egg-plant cultivars. The plant stimulant did not affect significantly chillies yield, but Atonik 0,5 ml/l applied after fruit set and twice again after 7 day intervals showed a tendency to increase the total weight and the number of fruits in the plant. Total weight, number and weight average of eggplant fruits were unaffected or reduced by Atonik application at the flowering, at the flowering and twice again after intervals of 7 days, and after fruit set.
