Evaluación de sustratos orgánicos con la aplicación de Trichotic para la obtención de plantas de mora (Rubus glaucus Benth)

Abstract

The investigation was carried out on Mr. EfraínVaca property, located in the Presidente Urbina parish, Píllaro canton, Tungurahua province; with an altitude of 2 803 m, with the a purpose of evaluating three rooting substrates (compost S1, earthworm humus S2 and soil of zone S3) and three doses of Trichotic (2, 4 and 6 g/l), in the propagation of blackberry cultivation (Rubus glaucus Benth). The treatments were nine. The completely randomized block design was used in a 3 x 3 factorial arrangement with five replications. We performed the analysis of variance, Tukey significance tests at 5% and orthogonal polynomials. The analysis of costs per treatment was also calculated. The best results were obtained with humus worm (S2), when the seedlings with the highest growth in outbreak length at 30 days (11,88 cm) and at 45 days (20,01 cm), better length (30, 71 cm) and higher root system volume (257,33 cc), with a better number of secondary roots (61,20 roots), reducing the days to the transplant (45,00 days); so it is the appropriate organic substrate for the propagation of blackerry cultivation. Applying Trichotic (D3) at the 6 g/l dose yielded the best results when seedlings with a longer shoot length were detected at 30 days (11,28 cm) and at 45 days (18,35 cm); better growth in length (29,19 cm) and volume of the root system (198,67 cc) and higher number of secondary roots (63,13 roots). The cost analysis, it is deduced that the lowest cost of production corresponded to the treatment S3D1 (land of the zone, dose of 2 g/l), based on that this treatment does not consider the cost of the soil and is the lowest cost of Trichotic . The highest cost, for its part, corresponded to the treatment S2D1 (humus worm, dose of 2 g / l). Hump of worm. Organic substrate from (Eisenia foetida) decomposition of debris from vegetative material. Trichotic.Soil saprophytes, known for the antagonistic effect against phytopathogens, which benefits the development of plants.
