Abstract
<p><strong>Background.</strong> The use of biosolids in agriculture allows to supply essential nutrients for the plant development. <strong>Objective</strong>. To evaluate the effect of supplying swine biosolids on the physio-agronomic characteristics and incidence of pests in X'catik pepper. <strong>Methodology.</strong> The experiment was carried out under greenhouse conditions and set in a randomized block experimental design with four replicates. Three different levels of biosolids were evaluated (500, 750 and 1000 g plant<sup>-1</sup>) and the control (no supply of biosolid). <strong>Results.</strong> Plants treated with 750 g de biosólido had the highest net carbon assimilation rate (A<sub>N</sub>) and the lowest intracellular carbon (Ci), likewise, there was a trend of higher values for the yield components in this treatment. The population density of <em>B. tabaci</em> and the damage by <em>Poliphagotarsonemus latus</em> was similar among treatments. <strong>Implications.</strong> The use of swine biosolid in agriculture represent a feasible alternative to enhance the plant physiological condition and potentially the yield in horticultural crops. <strong>Conclusion</strong>. The supply of 750 g plant<sup>-1</sup> of swine biosolid improved the physiological parameters in the X'catik pepper plants, had no effect on pest damage, but showed a strong tendency to increase yield.</p>
