Abstract
This research work had as the aim of verifying the efficiency of five combined concentrations of hydrogen cyanamide (CH) in four consecutive pruning times of sprouting vine and harvest anticipation of ‘Niagara Rosada’ in the county of Ponta Grossa, PR. The experiment had a factorial design (4 x 5) with 3 replications and 3 plants per parcel. The analysis were sprouting percentage, number of clusters per plant, rate of production and average weight per cluster. The effect of CH was shown only at the first pruned time when sprouting but the occurrence of frosting decreased the yield. The delay in the process of pruning showed a higher number of cluster per plant, which consequently resulted in yield increase.

O experimento foi conduzido com o objetivo de verificar a eficiência da combinação de cinco concentrações de cianamida hidrogenada (CH) e quatro épocas de poda, na quebra da dormência e antecipação da colheita da videira ‘Niagara Rosada’ no município de Ponta Grossa – PR. O delineamento experimental foi em blocos casualizados no esquema fatorial 4 x 5 (épocas de poda x concentrações de CH) , com 3 repetições e 3 plantas por parcela. Foram analisados a porcentagem de brotação, o número de cachos por planta, a produção por planta e a massa média dos cachos. Houve efeito da aplicação de cianamida hidrogenada no aumento da brotação das gemas apenas para a primeira época de poda (06/08/2007). A primeira época de poda antecipou em uma semana a colheita, embora a ocorrência de geadas tenha prejudicado a produção. O atraso na época de poda proporcionou um maior número de cachos por planta e a maior produção.
