“…In this research, the soil water potencial (Ψs) varied because of time and not of the PD (Figure 1), and the differences in time were related to changes in precipitation. The results contrast with those reported by Bermúdez-Florez et al (2018) and Honda et al (2019), those who found that low PDs were related to high soil moisture due to low water consumption. This behavior can be attributed to the fact that arracacha adjusts the root growth based on intraspecific competition in such a way that root tissue area in the soil does not change according to PD.…”

“…The leaf temperature variability indirectly estimates transpiration and gs, indicating water deficit (Biju et al, 2018) that could be generated by the effect of high PD (Bermúdez-Florez et al, 2018;Honda et al, 2019). The leaf temperature depression (LTD) did not show significant differences between PDs except for 240 DAS in the PD of 30,000 plants ha -1 (Figure 5A), and this was related to the water use efficiency (WUEi) (Figure 5C).…”

“…High population densities increase water uptake attributed to a higher amount of root tissue expressed by a higher number of plants that generate a reduction of soil water potential (Luo et al, 2011;Bermúdez-Florez et al, 2018;Honda et al, 2019). This plant water status alteration produces stomatal and non-stomatal limitations of photosynthesis (Chastain et al, 2016;Drake et al, 2017).…”

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.

“…On the other hand, the soil moisture in shaded sites oscillated around 50%, which is the limit for water excess, from July to November (Figure 6). Water deficit was defined as <30% of volumetric soil moisture, and water excess at >50%, as in the study by [48].…”

Does Shade Impact Coffee Yield, Tree Trunk, and Soil Moisture on Coffea canephora Plantations in Mondulkiri, Cambodia?

Shade is a natural condition for coffee plants; however, unshaded plantations currently predominate in Asia. The benefits of shading increase as the environment becomes less favorable for coffee cultivation, e.g., because of climate change. It is necessary to determine the effects of shade on the yield of Coffea canephora and on the soil water availability. Therefore, three coffee plantations (of 3, 6, and 9 ha) in the province of Mondulkiri, Cambodia, were selected to evaluate the effect of shade on Coffea canephora yields, coffee bush trunk changes, and soil moisture. Our study shows that shade-grown coffee delivers the same yields as coffee that is grown without shading in terms of coffee bean weight or size (comparing average values and bean variability), the total weight of coffee fruits per coffee shrub and the total weight of 100 fruits (fresh and dry). Additionally, fruit ripeness was not influenced by shade in terms of variability nor in terms of a possible delay in ripening. There was no difference in the coffee stem diameter changes between shaded and sunny sites, although the soil moisture was shown to be higher throughout the shaded sites.

“…In this sense, Bermúdez‐Florez et al. (2018) analyzed differences in the behavior of volumetric soil moisture with respect to three different spatial arrangements, obtaining evidence of the influence of density sowing and seasonal atmospheric conditions on ET c . The eddy covariance (EC) method is a tool used worldwide to estimate ET c through energy balance, integrating the soil–plant atmosphere components.…”

Evapotranspiration and crop coefficients for coffee production systems in Colombia using the eddy covariance method

To optimize coffee (Coffea arabica L.) production in Colombia, adaptation strategies that improve water use must be developed. Therefore, the objective of this study was to determine evapotranspiration under standard conditions (ETc), reference evapotranspiration (ETo), and the crop coefficient (Kc) of coffee plants interplanted between maize (Zea mays L.) (coffee–maize) for the first 12 mo of growth and coffee grown without maize from 13 to 46 m after transplanting (MAT). In this study, ETc was measured using the eddy covariance method. The ETc of coffee–maize ranged from 4.17 to 4.71 mm d–1, while ETc of coffee–sun averaged 4.32 ± 0.07 mm d–1 between 13 and 24 MAT and 4.09 ± 0.03 mm d–1 between 25 and 43 MAT for coffee trees in the reproductive stage. The Kc was 0.87 for coffee plants between 0 and 12 MAT, 0.98 ± 0.01 between 13 and 24 MAT, and 0.97 ± 0.02 between 25 and 43 MAT. Maize intercropped between coffee trees produced an adapted microclimate for the first 2 mo, allowing energy used for evapotranspiration processes (latent heat flux) to be greater than energy used for air warming (sensible heat flux), although there was low soil water availability. Kc values are a foundation for optimizing coffee crop water use under climate and soil conditions for the intertropical Andean hillside region.
