Resumen
Objective: To convince Mexican producers and authorities about the potential of biofertilizers in different regional agricultural systems. In addition, using validation and demonstration plots with different crops, INIFAP trained producers in the appropriate use of biofertilizers.
Design/methodology/approach: The actions were carried out throughout the country since the 1999 SS cycle. The microorganisms used in this project were Azospirillum brasilense, Rhizobium etli, Bradyrhizobium diazoefficiens, and Rhizophagus intraradices. The training courses were attended by 9,229 producers. Biofertilization was carried out in 1,882,236 ha and 3,370,440 doses of biofertilizers were applied during three agricultural cycles. In conclusion, biofertilizers (individually or in co-inoculation treatments) can increase crop yield under various environmental and management conditions.
Results: In most crops, bacteria/fungi co-inoculation promoted a greater growth and yield in host crops. According to the data obtained by the biofertilization program of INIFAP, in Mexico, biofertilization can feasibly achieve more sustainable and profitable agricultural systems than conventional agricultural systems that use agrochemicals. In addition, the effective symbiosis of rhizobia promoted bean growth.
Findings/conclusions: Extensive and is readily available research about biofertilizers proves that these microorganisms can increase yield, while providing enough nutrients to crops.
