Eficiencia del uso del agua en la producción vegetal”

Water use efficiency (WUE) is described by the ratio of grams of water transpired through a crop to grams of dry confidence produced. More water-use efficient species produce more dry matter per gram of water transpired. Recent biomass production in any crop is strongly decided by the amount of water held. This becomes clear when quantifying the annual production (crop or accumulated biomass in kg/ha) and the water used (m3/ha). Water deficit conditions are very common in the life cycle of plants and, in fact, water availability turns out to be the main factor conditioning plant growth and crop yield worldwide. The information obtained was carried out through the technique of analysis, synthesis and summary, with the purpose of informing the reader about the efficiency of water use in plant production. From the above detailed, it was determined that water use efficiency at the plant stage is a parameter with an especially experimental cost, since it is also obtained in managed situations where the flora is in pots or in structures where the water consumed can be correctly measured. Biomass production without water is impossible for plants. The question is to better understand whether or not it is a single value, whether or not it varies with the type of plant, whether or not it depends on environmental conditions. Between 100 and 1,000 grams of water are needed to produce one gram of biomass, and the exact value depends on both the type of plant and the environmental conditions. Water consumption is also strongly associated with the leaf neighborhood index. It is feasible to alter this function through crop management practices including: cultivar choice, planting density, planting body, and use of growth regulators.

La eficiencia en el uso del agua (EUA) se describe a través de la relación entre los gramos de agua transpirados por medio de un cultivo y los gramos de confianza seca producidos. Las especies más eficientes en el uso del agua producen más materia seca por gramo de agua transpirada. La producción de biomasa reciente en cualquier cultivo está fuertemente decidida por la cantidad de agua que se tenga. Esto queda claro al cuantificar la producción anual (cosecha o biomasa acumulada en kg/ha) y el agua utilizada (m3/ha). Las condiciones de déficit hídrico son muy comunes en el ciclo de vida de las plantas y, en realidad, la disponibilidad de agua resulta ser el principal factor que condiciona el crecimiento de las plantas y el rendimiento de los cultivos en todo el mundo. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre la eficiencia del uso del agua en la producción vegetal. Por lo anteriormente detallado se determinó que el rendimiento en el uso del agua en etapa de planta es un parámetro con un costo especialmente experimental, ya que también se obtiene en situaciones manejadas donde la flora se encuentra en macetas o en estructuras donde se puede medir correctamente el agua consumida. La producción de biomasa sin agua es imposible para las plantas. La cuestión es comprender mejor si se trata o no de un valor único, si varía con el tipo de planta, si depende o no de las condiciones ambientales. Para producir un gramo de biomasa se necesitan entre 100 y 1.000 gramos de agua, y el valor exacto depende tanto del tipo de planta como de las condiciones ambientales. El consumo de agua también está fuertemente asociado con el índice de vecindad de la hoja. Es factible alterar esta función a través de prácticas de manejo de cultivos que incluyen: elección de cultivares, densidad de siembra, cuerpo de siembra y uso de reguladores de crecimiento.
