Assessment of a Remote Sensing Energy Balance Methodology (SEBAL) Using Different Interpolation Methods to Determine Evapotranspiration in a Citrus Orchard por Jiménez-Bello, Miguel Ángel, Castel, Juan R., Testi, Luca, Intrigliolo, Diego S.

“…The Perrier function was the best method for properly estimating the roughness momentum length for discontinuous canopies, as in citrus orchards. Crop height was estimated using LIDAR data. In general, SEBAL performed well for net radiation estimation but failed in soil heat flux estimation. …”

Manejo de malezas en el cultivo del plátano por Cayón C., Gerardo, Lozada Z., Efrén, Romero M., Carlos E.

“…Based on weed control research made by the Plant Physiology Program in ICA - Palmira in plantain crops,the following conclusion can be drawn: weeds can affect the growth of the stem by decreasing the diameter of the stem, size of the plant and its height. In this work is also discussed the different weed control methods developed in plantain crops, as well as the cost of weed control practices.…”

Shade canopy density variables in cocoa and coffee agroforestry systems por Somarriba, Eduardo, Saj, Stephane, Orozco‑Aguilar, Luis, Somarriba, Aurelio, Rapidel, Bruno

“…The use of these SCDV has two important limitations: (1) different combinations of values of the three SCDV variables generate very different shade tree stands (hence very different shading levels), and (2) Additional factors modify shading under shade canopies with constant SCDV values.This article uses the software ShadeMotion (www.shade motion. net) to show how 24 different, simple, even-sized, mono-layered, Cordia alliodora shade canopies with constant N, G and %Cov display significantly different shade levels and temporal patterns of shading depending on tree stem and crown diameter ratios, tree height, spatial planting configurations (square, random and alleys) and leaf fall patterns. …”

Destete precoz de becerras bajo condiciones desfavorables: El uso de varios niveles de heno de alfalfa por Butterworth, M.H., Renteria, J.J.

“…The third group was treated as the first group plus medium-quality alfalfa hay fed free choice. Body weight, height at the withers, thoracic perimeter, cannon-bone perimeter, body length, and consumption of the diets were determined weekly until each calf had reached an age of 14 weeks. …”

Germination and growth of Pinus caribaea directly sown into containers as influenced by shade, phosphate and captan por Geary, T.F., Avila Cortés, G., Hadley, H.H.

“…There was a high correlation between height and diameter when the effect of shade was removed, possibly indicating a dependent-independent variable relationship.The methods used in this experiment produced seedlings ready for planting in the field 27 weeks after sowing.…”

Variations in the performance of maize (Zea mayz) yield under reclaimed wastewater irrigation in south-eastern Australia : management of salinity, water and nutrient budgets por Peräläinen, Lina

“…However, some samples showed high salinity, still, the correlation with maize performance, measured as crop height (m), was very low (R2 0.02-0.44). Deep profile sampling could not be done in this study, hence, the salinity with depth was not explored. …”
