TORRES PEREZ, Juan Cristóbal et al. Evaluación del uso de microorganismos de montaña activados en el cultivo de rosas, Zinacantán, Chiapas, México. Siembra [online]. 2022, vol.9, n.1, e3500. ISSN 2477-8850.  https://doi.org/10.29166/siembra.v9i1.3500.

The research was carried out in the municipality of Zinacantán, Chiapas, Mexico, in an area of rose’s production in plastic greenhouses, located at 16° 45′ 35″ N latitude, 92° 43′ 20″ W and at an altitude of 2162 masl. The climate is dub-humid temperate with rains in summer, the temperature reaches an average of 21 °C and the accumulated annual average precipitation is 599 mm. The objective of this study was to evaluate the effect on plant growth of Activated Mountain Microorganisms (MMA) sprayed under two doses (10 % and 20 %) and two spraying frequencies (every 8 and every 15 days). The four treatments were evaluated under the conventional rose crop management, and one control of conventional crop management and another control of ecological crop management were included. The six treatments were set up in a completely randomized design, each treatment consisting of a seedbed, where two rows of rose plants were planted under a three-point planting system, each bed containing a total of 530 plants. The results indicate that the bio-fertilizer MMA at doses of 20 % sprayed every 15 days, and the MMA at doses of 20 % sprayed every 8 days were statistically superior, for stem length, stem diameter, number of leaves, length of leaves, width of leaves, flower size, and shelf life. Therefore, it is concluded that MMA at 20 % dose improves rose production indicators under greenhouse conditions.
