Abstract
If adaptability is defined as the ability of a crop (or variety) to respond positively to changes in agricultural conditions, the purpose of this study was to explore the adaptability and relative influence of environmental factors on Cucumber Sativus L. to a specific Mediterranean environmental and agroecological site: Huete (Cuenca, Central Spain). Cucumber requires high temperatures and soil moisture for a satisfactory yield and maintaining an optimum level of humidity is very favorable, which is easy to achieve for farmers in Huete. Abundant sunshine is needed and this is another reason to cultivate during the summer period; it is estimated that there were between 2700 and 2800 hours of sunshine in the Huete area. The study described here revealed that the soils are poorly developed and evolved, with a simple Ap-C or Ap-Bw-C morphology. The soils are friable, slightly adherent and somewhat dry and hard. A significant feature is the presence of good drainage and appreciable effective depth. Like other crops, cucumber plants are preferably grown on loose, well-drained soils, such as the soils studied here. Huete cucumber seems able to tolerate certain levels of soil salinity when compared to other species. The cucumbers are irrigated with water with moderate electrical conductivity without an appreciable decrease in yield. Small doses of salinity may be one of the factors that leads to the characteristics associated with Huete cucumber, an aspect that would need to be investigated more deeply. Substrate nutrients and moisture management are two major concerns regarding Cucumber Sativus L. crops in Huete. Elemental chemical analysis revealed that strontium abounds and this is attributed to the presence of this element in the gypsums. The results of this study open a new horizon in the study of the aptitude of the land and represent a useful step towards the specific site and, consequently, the sustainable management of land under cucumber cultivation. Further research into a wider range of soils, fertilizer compositions and release rates is required.
