Uso de diferentes substratos para produção de mudas de tomate

Abstract

Organic substrates can contain different formulas, being compounds or compounds of carbon sources and medium containing substances decomposed by microorganisms. They are prepared using different methodologies, giving rise to composting and vermicomposting. The organic substrates can be aggregated in a form of transformation to the use of seedlings, in the present work for the production of production products. (pH, electrical electrical conactivity, solid solids) (pH, electrical electrical conactivity, solid solids) total, fixed Kejelda total carbon, carbon and root ratio and density) different organic materials, chemically perform phytometric tests (total dry mass, solids solids), aerial mass and number of leaves) in replacement plants with different substrates and tomato, through commercial seedling pigment leaves, vermicompost and substrate derived from compost. The statistical methods used were: Intensely Randomized Design (DIC), analysis of variance (ANOVA) and compared with the use of the Key Test with 5% of significance. The verification of variables was done using Pearson's linear verification. At the end of the experiment, he obtained the best phytometric result in treatments T2 (100% organic compost) % commercial replacement).
