YANEZ YANEZ, Wilfrido et al. Effects of enriched compost with efficient microorganisms on the germination of recalcitrant seeds of breadfruit (Parkinson) Fosberg and Theobroma cacao L.. J. Selva Andina Biosph. [online]. 2016, vol.4, n.2, pp.100-108. ISSN 2308-3867.

The research was conducted at the Center for Research, Graduate Studies and Amazon Conservation (CIPA) of the Amazon State University, Ecuador. The purpose was to assess the effect of enriched compost Germination, day and day’s emergency transplantation two species of tropical origin and breadfruit Theobroma cacao. The experimental field is located in the province of Napo, 16'-1 and S and 77º 36'' 58'y 76'' W, at an altitude of 556 meters, with temperature between 18 and 32oC, average annual precipitation above 3000mm and relative humidity between 87 and 89%. An experimental design with five treatments in a randomized complete block design with three replications was applied. Treatments consisted of compost (1) MS, (2) lactic acid bacteria, (3) commercial yeast, (4) a combination thereof and (5) only compost, witness. It was determined that the compost mixture (T4) as a whole, has the greatest effect on the parameters of the seeds. Germination was found that in two of the T3 and T4 treatments significantly decreased the number of days to germination, in relation to the witness, 33 days and 13 days Artocarpus altilis, Theobroma cacao. The number of emerged plants, increase in both species with the addition of EM, lactic acid bacteria and commercial yeast (T4). a reduction is also reported in the days to transplant species studied to be significant particularly in cocoa. It was also determined that most bioburden corresponded to bacteria.
