Abstract
La industria del papel proveniente de celulosa tiene un crecimiento de 2.5% anual, sin embargo, existe la tendencia creciente del uso de papel reciclado para los procesos de fabricación. Durante este proceso se genera un residuo papelero que no tiene una disposición final adecuada hecho que contribuye a la contaminación ambiental. El objetivo del trabajo es establecer una formulación de compost de residuo papelero que pueda aplicarse al cultivo de maíz, evaluando su rendimiento como alternativa para la gestión de residuos de la industria papelera. El diseño experimental utilizado fue de bloques completamente al azar con cuatro tratamientos T1:15 t ha-1; T2:20 t ha-1; T3:25 t ha-1; T4:30 t ha-1 y cuatro repeticiones. No existió diferencia significativa en la relación raíz/vástago a los 40, 80 y 120 días después de la siembra, así como en el número de mazorcas por planta. Por otro lado, en el peso de mazorcas por planta, el rendimiento de forraje verde y rendimiento de materia seca el T4 presentó diferencia significativa. En conclusión, el compostaje en una relación 3:1 de residuo papelero y estiércol de vaca puede ser una opción viable en la gestión de residuos provenientes de la industria papelera ya que tiene efectos sobre el rendimiento de maíz.
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.
