Abstract

The experiment was carried out at Esalq/USP, Piracicaba/SP. The objective of this work was to study the effects of elevated CO₂ concentrations and water volume on pepper crops, Capsicum annum L. (Solanaceae), planted in pots inside plastic greenhouse. Four levels of CO₂ (367, 600, 800 and 1000µmol mol^-1) were applied daily through micro tubes installed at 3m high. A drip irrigation system, having one drip by plant, was used to irrigate them every other day and four water volumes (30,89L, 40,7L, 61,86L and 82,83L) with four replications were used. The fruit dry matter, root dry matter, shoot dry matter and total dry matter were analyzed. Increase of water volume and CO₂ concentration the dry matter production was high. Root dry matter reduced in the environment enriched with 1000ïmol mol^-1 for all water volume applied
