Water recharge before budbreak and/or deficit irrigation during summer: agronomic effects on cv. Tempranillo in the D.O. Ribera del Duero

Abstract

The availability of water in the soil and the water status of the vineyard are proving to be determining factors for crop management in the current context of climatic variation. For this reason, it is very useful to know the effect that water management, before and during the vegetative cycle, has on the agronomic response of the vineyard and the quality of grapes in order to guide crop decision-making.

A study is proposed on the vegetative, productive and qualitative response of cv. Tempranillo, grafted onto 110R, during the period 2021-2023, to soil water recharge before budbreak and to deficit irrigation (30% ETo) during the summer, with three treatments: recharge and no irrigation, recharge and irrigation, no recharge and irrigation. In a vineyard located in the D.O. Ribera del Duero and trelllis trained, 4 random blocks were established, with elementary plots of 48 vines.

The observed results show a clear impact of the application of deficit irrigation in summer compared to the water recharge of the soil profile before bud break, both on vegetative growth and on productive development. The influence of the water regime on grape quality showed variable annual trends depending on the chemical parameter analysed, with greater discrimination of the treatment not irrigated during the summer. The evaluation of the observed results requires the extension and deepening of the study in different types of soil.

Recarga hídrica antes de brotación y/o riego deficitario durante el verano: efectos agronómicos en cv. Tempranillo en la D.O. Ribera del Duero

Resumen. La disponibilidad de agua en el suelo y el estado hídrico del viñedo están revelándose como factores determinantes para el manejo del cultivo en el contexto actual de variación climática. Por este motivo, resulta muy conveniente conocer el efecto que la gestión hídrica, antes y durante el ciclo vegetativo, ejerce sobre la respuesta agronómica del viñedo y la calidad de la uva para orientar la toma de decisiones de cultivo.

Se plantea un trabajo sobre la respuesta vegetativa, productiva y cualitativa del cv. Tempranillo, injertado sobre 110R, durante el periodo 2021-2023, a la recarga hídrica del suelo antes de brotación y al riego deficitario (30% ETo) durante el verano, con tres tratamientos: recarga y no riego, recarga y riego, no recarga y riego. En un viñedo, ubicado en la D.O. Ribera del Duero y conducido en espaldera, se establecieron 4 bloques al azar, con parcelas elementales de 48 cepas.

Las respuestas observadas muestran una repercusión clara de la aplicación del riego deficitario en verano frente a la recarga hídrica del perfil del suelo antes de la brotación, tanto en el crecimiento vegetativo como en el desarrollo productivo. La influencia del régimen hídrico en la calidad de la uva mostró tendencias anuales variables dependiendo del parámetro químico analizado, con mayor discriminación del tratamiento no regado durante el verano. La valoración de los resultados observados requiere de la ampliación y la profundización del estudio en distintos tipos de suelo.
