“…The leaf gas exchange (A) was evaluated from the beginning to the end of root filling. Because in arracacha this phenological stage is susceptible to water deficit (Chaali et al, 2020). The results showed that A was twofold (Figure 4A) and the yield was four times (Figure 8A) higher than the local variety of arracacha described by Jaimez et al (2008).…”

“…This result suggests that arracacha plants were not subjected to water deficit. Hence, the variability of commercial yield was not generated by water deficit (Chaali et al, 2020).…”

“…These reductions in A can be related to foliar senescence processes and the low demand for carbohydrates of the commercial root at this phenological stage. Because the peak of dry matter accumulation is between 150 and 240 DAS (mid-stage) (Chaali et al, 2020). Hence, the A may be downregulated by the sourcesink relationship at late stage (>240 DAS).…”

“…The study was carried out between January and December of 2019 in the municipality of Cajamarca, province of Tolima, in Colombia, at the geographic coordinates 4°23'44.4" N and 75°28'08.5" W. The soil of the experimental area was an Andisol with a sandy loam dominant texture, granular structure, moderately developed, and good natural drainage (Chaali et al, 2020). Five population densities (PD) were evaluated (Table 1) in a completely randomized block design with three replicates, using a total of fifteen experimental units each with an area of 30 m 2 and six rows with a length of 5 m, using the three central rows as a useful plot.…”

Introduction. Arracacha (Arracacia xanthorrhiza Bancroft) a promising crop due to its nutritional and gastronomic relevance. Population density is an agronomic practice that increases water and radiation use efficiencies, maximizes the yield, and crop profitability. However, the selection of the optimal population density based on physiological, agronomic, and economic criteria for arracacha has not been studied. Objective. To describe the effect of different population densities on the physiology, yield, and profitability of arracacha. Materials and methods. The experiment was conducted in Cajamarca, Colombia in 2019. There, the soil water potential, relative chlorophyll content, photosynthesis, stomatal conductance, water use efficiency, leaf temperature depression, photosynthetic reflectance index, leaf area index, the fraction of light interception, light extinction coefficient, cracking index, yield, and profitability were evaluated. Results. The results showed that high population densities did not generate water deficit because there were no significant differences for the soil water potential, leaf temperature depression, and photosynthetic reflectance index. Furthermore, no nutritional deficiencies were evidenced because the relative chlorophyll content (<32 SPAD) was higher at the critical level. Due to this, no limitations were observed in leaf gas exchange processes. However, the densities of 25,000 and 30,000 plants ha-1 showed a higher fraction of light interception due to the increase in the leaf area index; this allowed to obtain a higher yield at these densities. Conclusion. The maximum yield (41.96 t ha-1) and profitability (US$ 15,333.06 ha-1) were reached with a population density of 22,222 plants ha-1.

En este estudio se utilizó el software Cropwat 8.0, con el fin de evaluar la huella hídrica del café en la estación experimental Pueblo Bello en el departamento del Cesar, el cual se ve reflejado en la sostenibilidad Ambiental, social y económica de la huella hídrica. Esta metodología se basó en el manual de huella hídrica propuesto por Hoekstra et al, en donde para calcular la huella hídrica se tomó como referencia los datos climáticos para los años 2017 y 2018, los cuales sirvieron para calcular la huella hídrica verde y el Agua Virtual. Finalmente, los resultados mostraron que la huella hídrica en el 2017 fue 84,24 m3/año y para el 2018 fue 86,58 m3/año, lo cual demuestra que el consumo de agua en la estación experimental para estos años fue bajo, ya que para producir 1 Kg de café se requirió aproximadamente 0,3 litros de agua.
