• Abstract:

  The objective of this research was to evaluate doses of 1.25 L, 2.5 L, 3.75 L, 5 L, and 0 L of the biofertilizer Biocafécashi to control orange rust infestations on coffee plants at the El Cedro ranch in the community of Emiliano Zapata, Montecristo de Guerrero, Chiapas, Mexico. The following variables were evaluated in the field: percentage of orange rust infestation/coffee plant, average weight per dry parchment coffee bean/coffee plant, total weight of dry parchment coffee/coffee plant, average weight per dry cherry/coffee plant, and cost/benefit analysis. A completely randomized block design was used, consisting of five treatments with three replicates, for a total of 15 experimental units, with each Bourbon coffee plant representing one experimental unit and a 5 m separation between plants. The results indicated that for the variable percentage of orange rust infestation/coffee plant, there was a statistically significant difference (P<0.05), and treatment 4 with a dose of 5 L of Biocafécashi biofertilizer had the lowest percentage of coffee rust infestation at 13.39%. 
  Similarly, the average weight per dry parchment coffee bean/plant showed a statistically significant difference (P<0.05), with treatment 2 achieving the highest weight per bean at 0.575 g. On the other hand, the average weight per dry cherry/coffee plant showed a statistically significant difference (P<0.05), with treatment 4 having the highest weight per dry cherry at 0.389 g. According to the total weight of dry parchment coffee/plant, the treatment of 1,250 L of Biocafécashi biofertilizer recorded the highest yield with 10.78 q/ha-1 , followed by the 3.75 L and 5 L doses with a production of 7.14 q/ha-1 , 7.63 q/ha-1 , and the control produced 4.10 q/ha-1 , respectively. cost/benefit analysis, with a dose of 1.250 L of Biocafécashi biofertilizer, had a ratio of 2.95, indicating that the investment was recovered and, in addition, a profit of 1.95 pesos was obtained for each peso invested, with a net profit of $23,466.4 for the year.
