Abstract

With the aim of yielding potato seed tubers from true potato seed (TPS) ecologically and sustainably, three experiments were conduced at the National Institute of Agriculcural Sciences, San José de las Lajas, Havana province, betwen 1994 and 1998, on a compacted red Ferralitic soil, where two organic sources were tested as substrates, besides two sowing methods, direct and transplanting, different soil/manure proportions in the substrate composition and the best results combined and seed coinoculation with biofertilizers (Pseudomonas cepacia, Pseudomonas fluorescens and Azospirillum brasilense Sp-7 ) and mycorrhizal arbuscular fungus (Glomus fasciculatum), using 60 kg N. ha-1. Results showed a positive effect of the coinoculation (Glomus
fasciculatum + Pseudomonas cepacia) upon increasing yields. This result was more productive and economical than the use of chemical fertilizer (check).
