Program Begins to Optimize Water Use in New Table Grape Varieties

Published 2025년 5월 23일

Tridge summary

Table grape is Chile's most important export fruit, with nearly 42,000 hectares cultivated from Atacama to O'Higgins. Only in the Aconcagua Valley is 19% of that area concentrated - around 8,000 hectares - positioning itself as a key zone for this crop.

Today, this industry faces a double challenge: water scarcity, intensified by climate change, and productive modernization, marked by the incorporation of new varieties and rootstocks. The problem is that there is little information regarding how these new varietal combinations respond to current irrigation management, designed for traditional varieties that are now being phased out.

Do these new varieties require the same amount of water? Or do they demand a different water management? That is the key question that the Technological Absorption Program for Innovation by Corfo seeks to resolve, led by INIA, which aims to optimize water use in grape trellises.
