dc.description.abstractThe objective of this study was to evaluate potassium doses in the production of sweet pepper, 'Gaston' cultivar, and effects on soil solution extract, using extractors. The research was installed in the greenhouse of the Department of Soils and Environmental Resources of São Paulo State University Júlio de Mesquita Filho-Botucatu Campus, and the plants were carried in pots. The experimental design was a randomized block design, with four replicates, using four doses of K2O (363 kg ha-1, 726 kg ha-1, 1088 kg ha-1 and 1451 kg ha-1) applied via drip fertirrigation. Electrical conductivity and specific ion concentration of soil solution extracted weekly, plant height and yield were evaluated. The extractors allowed efficient monitoring and there was significant differences across treatments. Increase in salt concentration in the soil solution reduced plant height, number of fruits and yield. The dose, in addition liming, that provided the highest fruit yield was: 363 kg ha-1 of K2O with 39.2 t ha-1, with an average electrical conductivity over the cycle of 1.7 dS m-1 and concentration of 111 mg L-1 in soil solution extract.en
