FORERO-PINEDA, NICOLÁS et al. Effect of the physicochemical characteristics of soil and irrigation water on the quality of the bulb onion (Allium cepa L.) crop in the Usochicamocha irrigation and drainage district in Boyaca, Colombia. rev.colomb.cienc.hortic. [online]. 2022, vol.16, n.1, e14046.  Epub 14-Jan-2023. ISSN 2011-2173.  https://doi.org/10.17584/rcch.2022v16i1.14046.

The bulb onion crop is not only one of the main vegetable crops worldwide, but it is also considered one of the pillars of the regional agricultural economy in Boyaca. Despite being so important from the economic point of view, at the agricultural level this crop has several problems among which stand out the nutritional requirements and poor practices in terms of soil management and conservation. That is why it is important to understand what are the physicochemical variabilities of the soil associated with the crop and how these can be related to intrinsic processes at a local geographic scale. To determine the variability of soil physicochemical conditions in the bulb onion crop, a total of 15 zones of 50 × 50 m were analyzed within the Usochicamocha irrigation district. A total of 15 soil samples and 15 irrigation water samples were collected and subsequently analyzed in the laboratory. Information was obtained on pH, MO, EC, bulk density, soil texture, Ca, Mg, K, Na, P, ion load, cations, hardness and turbidity in the water samples. The results obtained allowed observing a significant relationship between crop attributes, physicochemical properties of soil and water in the different study zones. These results support the hypothesis of the existence of a synergy between the extrinsic and intrinsic properties of the crop and how they have a relationship between the quality attributes of the bulb onion crop.
