Comparison between different times of application of slow release nitrogen fertilizers on grapevines. Preliminary results.

Preliminary results are presented for the comparison of different N nutrition strategies at different dates for a vineyard (Pinot bianco clone 57 on 420 A rootstocks; established in 1990) in northeast Italy. Postharvest N supply as isobutylidene diurea (IBDU) or dicyandiamide (DCD) positively influenced total buds, sprouting buds and cluster numbers, and achieved more balanced plants according to Approved Viticultural Area (AVA) laws of the areas.
