Due to the fast changing competitive environment faced by organizations, companies are forced to find ways to quickly adapt to technological innovations, changing demands of customers, and strategic actions taken by competitors. The purpose of the paper is to further the relationship between top management team （TMT） strategic decision speed and firm performance, considering the team processes when making strategic decisions in the face of complex environments. Measures of TMT strategic decision speed, firm performance, team orientation, and environmental complexity were collected from 29 top management teams of Mexican companies, which represented a total of 118 questionnaires. Pearson correlations among the variables and moderated regression analyses were performed, to test the hypotheses included in the study. Results show a positive relation between environmental complexity and TMT strategic decision speed and between team orientation and speed. Furthermore, results show that there is a positive relation between TMT strategic decision speed and firm performance in the presence of team orientation. In other words, team orientation moderates the relationship between TMT strategic speed and firm performance. Among the implications for managers is that they must ensure effective team processes （e.g., building consensus, active participation, and trust among team members） when making strategic decisions in order for the firm to perform better.

The experiment was carried out in the greenhouse of the DEAg/UFCG, Campina Grande (PB), Brazil, to evaluate the growth and development of the bell pepper subjected to fertilization with biochar and nitrogen. The experiment was conducted in pots under greenhouse conditions. Treatments were arranged in a completely randomized design, in 4 × 4 factorial scheme, relative to four doses of biochar (0;7;14 and 21 m3⋅ha−1) and four doses of nitrogen (0;40;80 and 120 kg⋅ha−1), with three replicates. Considering the analysis of growth of bell pepper plants during the first 45 DAS, is recommended the average dose of biochar of 19 m3⋅ha−1 on vegetable behavior. Under the conditions of the experiment, nitrogen favored only the absolute growth rate of plant height and the stem diameter.
