Evaluación de dos abonos orgánicos y nitrato de calcio, en el rendimiento de papa (Solanum tuberosum) variedad chaucha.

Abstract

The aim of this research was to evaluate the effect of two organic fertilizers and calcium nitrate on the yield of potato (Solanum tuberosum), variety chaucha, using a randomized complete block design DBCA bifactorial (3x3), with 3 replications and a total of 27 experimental units, considering as treatments two organic fertilizers (Bokashi and Gallinaza) and a synthetic fertilizer (calcium nitrate) at different dosages of 50, 100, and 150 kg/ha of nitrogen. The following parameters were evaluated: percentage of emergence, days to flowering, number of tubers/plant, weight of tubers/category in grams/plant, yield per hectare in kg/ha and the economic analysis by means of benefit/cost ratio. In agronomic area, there was a great difference between treatments, with the exception of the percentage of emergence, where there were no significant differences, with chicken manure being the fertilizer that presented the best characteristics; in yield, it was determined that the organic fertilizer chicken manure at a dose of 150 kg/ha of nitrogen, presented the best yield, with 13914.13 kg/ha in the potato chaucha crop. In reference to benefit-cost ratio the treatment with poultry manure at a dose of 150 kg/ha of nitrogen presented the highest Benefit/Cost with a gain of 1.37 USD, It is suggested the application of poultry manure at a dose of 150 kg /ha of nitrogen to obtain a higher agronomic and economic yield.
