Evaluación de tres dosis de fertiriego y tres dosis de materia organica en el cultivo de mora (Rubus glaucus Benth) TUNSHI-CER.

Abstract

This investigation aimed to evaluate three doses of fertigation and organic matter in the blackberry crop (Rubus glaucus Benth) TUNSHI-EIC. A randomized complete block design (RCBD) with bifactorial arrangement in divided plots with 12 treatments and three replications was used. The treatments corresponded to three fertigation doses with a three mm sheet, denominated INIAP Recommendation in Kg/Ha (330 N, 60 P2O5, 300 K2O, 74 Ca, 48 Mg, 48 S), 50% more than the INIAP recommendation, 50% less than the INIAP recommendation and an absolute control and three increasing doses of organic matter in the form of Ecoabonaza (0, 1.5 and 3 Mg/Ha). For the evaluation of the treatments, the percentage of shoot emergence 15 days after transplanting, the height of the flag branch, the number of leaves, the diameter of the stem, the number of flowers, and the economic analysis of the treatments by means of the benefit/cost ratio were evaluated. It was determined that the treatment indicated for the blackberry crop (Rubus glaucus Benth) in its vegetative stage was 5 (A2B2) which corresponds to +50% of the dose recommended by INIAP (330 N, 60 P205, 300 K2O, 74 Ca, 48 Mg, 48 S) and 1.5 Mg of organic matter (Ecoabonaza) because it produced the highest number of flowers with an average of 93.67. In the economic analysis with the Benefit/Cost Ratio for treatment B2 a better benefit is obtained with 37.57, that means that, for each dollar invested a benefit of 37.57 flowers is obtained. It is concluded that treatment 5 (A2B2) which corresponds to +50% of the dose recommended by INIAP and 1.5 Mg of organic matter (Ecoabonaza) have a significant influence on the vegetative growth of the blackberry crop (Rubus glaucus Benth) and therefore its use is recommended.
