Accepted 16 May, 2017 The replacement of mineral fertilizer in papaya crop with biofertilizer based on Glomus spp. and Azospirillum spp., can to increase the productivity in this crop, moreover to improve soil conditions. The aim of the study was to determine the quality of papayas seedling, variety "Red Maradol", obtained with the use of Glomus intraradices and Azospirillum brasilense, as biofertilizers for production of plants.The experiment was developed at greenhouse of High Study School of Xalostoc, Morelos. Was used a completely randomized design, with eight treatment and five repetitions: G. intraradices along (Gl), A. brasilense along (Az), Fertilizer 8-24-0 along (F), mixture of Gl, Az and fertilizer 8-24-0 (Gl+ Az + F), mixture of Az and F (Az + F), mixture of Gl and F (Gl + F), mixture of Gl and Az (Gl + Az); and the witness (T), without fertilization. These were applicated twice, on papaya seeds and in the sowing over the seedling. Such effect was evaluated using the variables: plant height, stem diameter, radicular volume, fresh total weight, dry total weight, foliage fresh weight, root fresh weight, as well as the seedling quality index by the Dickson method. The results shown that the biofertilizer G. intraradices and A. brasilense improved the nutrient uptake and stimulated the growth of papaya plants, when were applied together and with mineral fertilizer (8:24:0). The applications of G. intraradices by separated, get the best quality of the plantule, getting better radicular develop of it.

INTRODUCTION Chemical fertilizers are important in plant nutrition, however their irrational use has as a consequence *Corresponding Author’s Email: santaclara57@yahoo.es negative effects on the health of man and our environment, besides the excess or deficiency of an element, can increase the succulence of the crop, early maturation and reduction in post-harvest .
