Growth and Development of Bell Peppers Submitted to Fertilization with Biochar and Nitrogen

Abstract

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.
