Growing peppers for ornamental purposes has strong appeal in the consumer market and abroad. This fact is due to the characteristics of profitability and adding value to the product. Moreover, the cultivation of pepper has great socio-economic importance due to the employment of large numbers of skilled manpower. However, the commercial success of this activity depends on the consumer appeal conferred by the harmony of the plant with the container used, which is obtained by pruning, substrates, regulators use different volumes of vessel, among others. Thus, this study aimed to determine the effect of different substrates and the application of pruning in the production of four pepper genotypes (Pirâmide Ornamental, Biquinho, MG 7073, BGH 1039). Evaluated two types of substrates: commercial substrate (Bioplant®) and Land of garden flowers purchased in local and two pruning conditions, plants with two stems and plants with three stems. There was no difference in earliness between plants grown in substrate Bioplant® and Earth Garden, in which the genotypes BGH 1039 and Pirâmide Ornamental reached the spot trading at 60 DAT. However, in this same period the plants of both genotypes that were developed in substrate Bioplant® showed higher plant height, total height, crown diameter, leaf number and number of fruits per plant. Therefore, all growth variables evaluated were affected by different substrates in all genotypes. Plants that have developed in the substrate Bioplant® had to be better developed. The pruning did not affect the precocity of BGH 1039 genotypes and Pirâmide Ornamental, which reached the ideal point of sale at 60 DAT. The pruning was not effective for the Biquinho and access cultivar MG 7073, it increased the size of the plants and the canopy became asymmetric respective. However, both were effective pruning conditions for access to cultivate and BGH 1039, Pirâmide Ornamental, providing a denser canopy without changing the height of the plants.
