The work was carried out in the Valle Cieneguillo Sur; Sector ATEA (Association of Agricultural Extension Technicians) to 9 km of the north of Piura, in a plantation of lemon tree of 7 years with distancing of 7x7 m2, lasted 22 months (January 2016 - November 2017), under sandy soil (92% sand) and 0.13% organic matter.The design Blocks Completely Random was used. The experimental unit was a tree in production.The factors under study were: 110 (N) 50 P2O5 120 K2O 25 Ca (D1), 210 (N) 100 P2O5 150 K2O 80 Ca (D2), 280 (N) 120 P2O5 180 K2O 120 Ca (D3), 50% Rice husk + 50% Organic matter (C1) and 75% Rice husk + 25% organic matter (C2); the combination determined the treatments: T1 (D1C1), T2 (D1C2), T3 (D2C1), T4 (D2C2), T5 (D3C1), T6 (D3C2) and T0 (without applying).With the results obtained, it was concluded: There are no statistical differences between the treatments on the number of first...

El trabajo se realizó en el Valle Cieneguillo Sur; Sector ATEA (Asociación de Técnicos Extensionistas Agropecuarios) a 9 Km del norte de Piura, en una plantación de limonero de 7 años con distanciamiento de 7x7 m2, duró 22 meses (enero 2016 - noviembre 2017), bajo suelo arenoso (92 % arena) y 0.13% de materia orgánica.Se empleó el diseño Bloques Completamente al Azar. La unidad experimental fue un árbol en producción.Los factores en estudio fueron: 110 (N) 50 P2O5 120 K2O 25 Ca (D1), 210 (N) 100 P2O5 150 K2O 80 Ca (D2), 280 (N) 120 P2O5 180 K2O 120 Ca (D3), 50 % Cascarilla de arroz + 50 % materia Orgánica (C1) y 75% Cascarilla de arroz + 25 % materia orgánica (C2); la combinación determinó los tratamientos: T1 (D1C1), T2 (D1C2), T3 (D2C1), T4 (D2C2), T5 (D3C1), T6 (D3C2) y T0 (sin aplicar).Con los resultados obtenidos se concluyó: No existen diferencias estadísticas entr...
