Abstract
The main drawback of the forcing vine regrowth technique is the loss of yield (Martínez de Toda, 2020). In order to avoid such loss of yield and not eliminate the primary clusters already formed on the primary shoots, it is possible to force the development of the latent buds of the fifth and sixth nodes, while maintaining the clusters on the main shoots. In this way, the yield of the forced buds can be added to the normal or primary yield of the shoots. In this article, experiments carried out on Grenache, Tempranillo and Maturana Tinta varieties in La Rioja (Spain) are presented.

Pinot Noir: Myth or Reality?”2 in which this question is addressed through a one-year experiment using one cultivar grown in pots
Summary
Delays of about 13 days for the main clusters and of about 35 days for the clusters of the forced shoots were observed for grape ripening measured at around 22-23 oBrix, when comparing the forced treatments to the. *The experiment on the Grenache variety is it is possible to obtain a second crop from the forced loTcaabtleed1.inEfBfeacdtasroáfnf,oarctin6g2t0rematma.esn.tl.s aonndvitnheepehxepneorloimgye.n*tsTohne etxhpeeTreimmepnrtaonnilltoheanGdreMnaactuhreavnaariTeitnytais vloacraietetidesin buds, which can be added to the first crop from the main aBreadlaorcáante, datin62L0ogmroañ.os.,l.aatn3d7t0hemexap.esr.li.ments on the Tempranillo and Maturana Tinta varieties are located in Logroño, at 370 m a.s.l.
