MENA CHACON, Laydy Mitsu; SARMIENTO SARMIENTO, Guido Juan  e  CAMARGO SALCEDO, Patricia. Impact of the integral fertilizer on strawberry yield and quality (Fragaria x ananassa Duch.) cv. Selva under a drip irrigation system and plastic. Scientia Agropecuaria [online]. 2017, vol.8, n.4, pp.357-366. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2017.04.07.

The objective of the research was to determine the effect of integral fertilization on fruit quality and yield of strawberry cv. Selva, its incidence in the respiration rate and soil fertility; it was carried out in the Santa Teresa farm of Cayma, Arequipa Peru. The treatments resulted from integrating 3 levels of chemical fertilization: 0%; 50% and 100% of the formulation: 200 N, 60 K2O and 60 P2O5 and 3 levels of organic fertilization: 0%; 50% and 100% of the formulation: 100 L of Humega, 12 L of Bioflora Phos and 60 L of Bioflora Potash; evaluating 9 treatments with 3 repetitions, in randomized complete block design with factorial arrangement 3 x 3. There was no significant statistical effect on fruit quality. The treatment with 50% of chemical fertilization and 50% of organic fertilization achieved the highest yield of strawberry fruits (17 114.63 kg · ha-1) being 13.25% of extra category; 57.62% of first; 25.18% of second; 2.06% of third and 1.90% of waste. The respiration rate and soil fertility showed no significant statistical difference; except at 80 days after the transplant, where 100% organic fertilization increased the respiration rate.
