Evaluación de tres dosis de fertirriego y dos dosis de gallinaza en el cultivo de papa (Solanum tuberosum l.) variedad Superchola en C.E.R. Tunshi

Abstract

The aim was to evaluate three doses of fertigation and two doses of poultry manure on potato (Solanum tuberosum L.) superchola variety at Tunshi Irrigation Experimental Center. A bifactorial randomized complete block experimental design (RCBD) in split-plot arrangement was used, with twelve treatments and four replications. The treatments included three fertigation doses (recommended dose, recommended dose plus 50%, recommended dose minus 50%) and an absolute control, combined with two doses of poultry manure (3 t/ha and 2 t/ha) and an absolute control. The number of stems per plant, percentage of emergence, leaf area index (LAI), yield and tuber categorization were evaluated. The results obtained showed that there were no significant differences in the percentage of emergence, number of stems per plant and leaf area index. However, in terms of yield, significant differences were found. The best results were obtained with the combination of the recommended dose plus 50% fertigation and a dose of 3 t/ha of poultry manure, reaching a yield of 11 t/ha. In addition, this combination achieved the best values in the benefit-cost ratio, with a value of 1.16, positioning itself as the most efficient option for the potato crop to reach its right development.
