Abstract
The use of polymers composed by polyacrylamines (Silos de aguaTM) could be a suitable strategy to enhance water saving in agriculture.
In this study, the effect of the application of polyacrylamines into the soil on vegetative development, plant production, earliness and fruits quality in artichoke was evaluated.
Three artichoke (Cynara scolymus L.) cultivars (Calico, Symphony, Blanca de Tudela) were divided into two groups, each with and without polyacrylamines and data were recorded for a two-year period.
Those plants growing in presence of polyacrylamines received 50% of the standard irrigation volume.
Results showed that production of plants growing in presence of polyacrylamines was similar to those growing under standard conditions and no statistical significances were detected with the exception of Symphony where the production was significantly higher in the standard culture (5.39 kg/plant). On the other hand, a decrease in average fruit weight was detected in plants grown with polyacrylamines in Calico and Symphony where differences reached 200 g.
Plant development was not significantly affected, however, a decrease in plant width was observed under polyacrylamines treatment.
The polyacrylamine treatment was not able to overcome the drought period, decreasing head quality when a 50% water reduction was applied.
