ADRIANO ANAYA, María de Lourdes et al. Biofertilizer of organic coffee in stage of seedlings in Chiapas, Mexico. Rev. Mex. Cienc. Agríc [online]. 2011, vol.2, n.3, pp. 417-431. ISSN 2007-0934.

In Chiapas, c offee seedlings product ion is conventionally done with chemical fertilizers. Organic coffee production requires see dlings nutrition with biofertilizers and therefore the objective was to evaluate the effect of some of these in coffee seedlings development (Coffee arabica) Bourbon variety in a nursery. The experiment was conducted during 2007 and 2008 in Cacahohatan, Chiapas. Inoculants were a strain of Glomus intraradices Schenck and Smith and strains of PACHAZ08 of Azotobacter and Azospirillum 11B. Factorial designs 23 were used with eight treatments and 100 repetitions per treatment. In inoculated seedlings, 4 samples were made at intervals of 28 days, measuring height, leaves length, root length, dried leaves and roots weight, chlorophyll and nitrogen content, and root colonization by inoculants. Data were subjected to variance analysis and means comparison by Tukey p≤ 0.05. Best morphological and biochemical characteristics of seedlings were obtained with Azospirillum alone or coinoculated with Glomus and Azotobacter and were statistically the best treatments. Azospirillum modified root architecture and stimulated mycorrhization. Diazotrophics were antagonistic, but it was inhibited by Glomus. The three organisms' interaction induced a better use of nutrients, water, photosynthetic capacity and greater accumulation of carbon biomass in seedlings.
