“…The RDI practices have been used in row crops or horticulture crops such as sweet corn (Zea mays L.) (Assouline et al 2002), potato (Solanum tuberosum L.) (Fabeiro et al 2001), and eggplant (Solanum surattense L.) (Kirnak et al 2002). Little has been done with spring wheat, particularly in arid environments.…”

“…Rice fields are characterized by standing water during most of their cultivation period, which provides a unique opportunity for the study of ET estimation. On the contrary, potato, which ranks the fourth largest among the world's agricultural products in production volume and is the leading non-grain commodity in the global food system [17], is widely planted in water-stressed conditions without manual irrigation in intensive agricultural areas in East Asia. As there have been few reports about the PM-KP model for rice and potato, it would be a meaningful practice to carry out a study on the validation and suitability of the PM-KP model in these regions.…”

Estimation of evapotranspiration plays an important role in understanding the water cycle on the earth, especially the water budget in agricultural ecosystems. The parameterization approach of the Penman-Monteith-Katerji-Perrier (PM-KP) model, accounting for the influence of meteorological variables and aerodynamic resistance on surface resistance, was proposed in the literature, but it has not been applied to Asian croplands, and its error and sensitivity have not been reported yet. In this study, the estimation of evapotranspiration on half-hourly scale was carried out for two typical East Asian cropland research sites, and evaluated by using eddy-covariance measurements corrected with the energy-balance-closure concept. Sensitivity coefficients as well as systematic bias and random errors of the PM-KP approach were used to evaluate the model performance. Different distributions of the calibration coefficients between different crops were reported for the first time, indicating that the calibration of this model was more stable for the rice field than for the potato field. The commonly-used parameterization approach suggested by the Food and Agriculture Organization (FAO) was used as reference and was site-specifically optimized. The results suggest that the PM-KP approach would be a better alternative than the PM-FAO approach for estimating evapotranspiration for the flooded rice field, and an acceptable alternative for rain-fed croplands when the soil is well watered and the air is humid during the summer monsoon.

“…Potato (Solanum tuberosum L.) rates fourth among the world's agricultural products in production volume, after wheat, rice and corn (Fabeiro et al 2001). In China, the potato cultivation area was 4.72 million ha in 2000, mainly concentrated in North China.…”

Potato evapotranspiration and yield under different drip irrigation regimes

A field experiment comparing different irrigation frequencies and soil matric potential thresholds on potato evapotranspiration (ET), yield (Y) and water-use efficiency (WUE) was carried out in a loam soil. The experiment included five treatments for soil matric potential: F1 (-15 kPa), F2 (-25 kPa), F3 (-35 kPa), F4 (-45 kPa) and F5 (-55 kPa) and six treatments for irrigation frequency: N1 (once every day), N2 (once every 2 days), N3 (once every 3 days), N4 (once every 4 days), N6 (once every 6 days) and N8 (once every 8 days). Results indicate that both soil matric potential and drip irrigation frequency influenced potato ET, Y and WUE. Potato ET increased as irrigation frequency and soil matric potential increased. Comparing soil water potential, the highest ET was 63.4 mm (32.1%) more than the lowest value. Based on irrigation frequency treatments, the highest ET was 36.7 mm (19.2%) more than the lowest value. Potato Y and WUE were also found to increase as irrigation frequency increased. Potato Y increased with an increase in soil water potential then started to decrease. The highest Y and WUE values were achieved with a soil matric potential threshold of -25 kPa and an irrigation frequency of once a day.
