Microbial inoculants or bioinoculants currently have great ecological and economic importance in agriculture. The study considers knowing the effectiveness of three commercial bioinoculants combined with half of chemical fertilization [CF 50% (50-15-00)], on plant characteristics and productivity of sorghum. At maturity, the greater plant height was obtained with Mycorrhiza INIFAP and Mycorrhiza INIFAP + CF 50%; while for stem diameter and fresh root weight, all treatments exceeded the control. Higher values of length of panicle, seeds per panicle and grain yield, were recorded with Mycorrhiza INIFAP + CF 50%, Ferbiliq + 50%, Biofertibuap-Sorghum CF + 50% CF and CF 100% (30-100-00). For weight of 100 seeds, the best treatments were Mycorrhiza INIFAP + CF 50%, Ferbiliq + CF 50% and Biofertibuap-Sorghum + CF 50%, which were competitive with 100% CF. The results indicate the possibility of reducing 50% chemical fertilization of sorghum under irrigated conditions, by seed inoculation of Mycorrhiza INIFAP, Ferbiliq or Biofertibuap-Sorghum.
