VELASQUEZ-BARBACHAN, Juan. Wastepaper composting applied to corn cultivation. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.15, pp.140-147. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v5i15.135.

The pulp paper industry has a growth rate of 2.5% per year; however, there is a growing trend towards the use of recycled paper in the manufacturing process. During this process, a paper waste is generated that does not have an adequate final disposal, a fact that contributes to environmental pollution. The objective of this work is to establish a compost formulation of paper residue that can be applied to the corn crop, evaluating its performance as an alternative for the management of paper industry residues. The experimental design used was a completely randomized block design with four treatments T1:15 t ha-1; T2:20 t ha-1; T3:25 t ha-1; T4:30 t ha-1 and four replicates. There was no significant difference in the root/shoot ratio at 40, 80 and 120 days after sowing, as well as in the number of ears per plant. On the other hand, in the weight of ears per plant, green forage yield and dry matter yield, T4 presented a significant difference. In conclusion, composting in a 3:1 ratio of paper residue and cow manure can be a viable option in the management of residues from the paper industry since it influences corn yield.
