The goal of the research was to find the best way to increase the productivity and biomass of corn plants using organic fertilizers. The researchers tested different levels of granular and liquid organic fertilizers on corn plants to see which combination worked best. They found that using 1000 kg/ha of granular organic fertilizer and 2 cc/L of liquid organic fertilizer resulted in the highest corn productivity and biomass. This combination is recommended for farmers looking to improve their corn crop yields.
