MARQUEZ-QUIROZ, César; LOPEZ-ESPINOSA, Sayani Teresa; CANO-RIOS, Pedro  e  MORENO-RESENDEZ, Alejandro. Organic fertilization: an alternative to produce piquín pepper under protected conditions. Rev. Chapingo Ser.Hortic [online]. 2013, vol.19, n.3, pp.279-286. ISSN 2007-4034.  https://doi.org/10.5154/r.rchsh.2012.12.072.

We conducted an experiment to evaluate the vermicompost tea (VCT) as organic fertilizer in combination with mixtures of sand, compost (C) and vermicompost (VC) in piquín pepper production grown under greenhouse conditions. During 2011-2012, plants of piquín pepper ecotype chilpaya were subjected to five fertilization treatments: sand + inorganic nutrient solution (control, F1); sand + VCT (F2); sand + C (1:1 ratio; v/v) + VCT (F3); sand + VC (1:1 ratio; v/v) + VCT (F4) and, sand + C + VC (2:1:1 ratio; v/v) + VCT (F5). Plants grown with control treatment (F1) had the highest yield, exceeding with 26.10, 9.00, 29.47 and 29.05 % the obtained yield in plants grown under F2, F3, F4 and F5 treatments respectively. With respect to the organic treatments, F3 treatment had the highest yield followed by F2 treatment. This study suggests that the VCT in combination with sand: C mixture, or just sand, was considered as an alternative for organic piquín pepper under greenhouse conditions.
