Indisputable ecological agriculture advances are closely linked to the proven risk, provoked to human health by foods containing toxic residuals derived from pesticides and mineral fertilizers, which has encouraged an international movement, intended to improve its biological quality by means of using available natural resources in agroecosystems. Cuba is not kept out of this situation and proposes some ecological alternatives to manage agricultural crops developed under a protected cultivation system, which are great chemical consumers. This work was carried out under protected cultivation housing conditions aimed at studying the effect of mycorrhizae and brassinosteroid analogues as ecological alternatives for tomato production under such productive system. There were seven completely randomized treatments referred to the single and combined application of bioproducts as well as its combination with mineral fertilization, so that they allowed reducing the mineral fertilization applied to crop under these conditions. According to results, when there are statistical differences compared to production control, ecological product combination stimulates plant growth and crop production. The combined application of mycorrhizae-brassinosteroid analogues (three times) + 50 % mineral fertilization enabled to obtain a larger amount of bunches (11.2) and fruits (21.0) per plant, with a fruiting percentage of 92.4 %, leading to an agricultural yield of 51.46 t.ha-1, the 50 % mineral fertilization reduction being significant to be applied under a protected cultivation system
