Resumo: |
This research aimed to evaluate the development and the production of the American grapevines cultivars Isabella and Ives, fertilized with different doses of cattle manure and wood ash applied in the Pre-planting and Bearing age. The experiments were carried out in commercial vineyards in Guarapuava-PR, Brazil. In 2009, it was implanted two trials, one with pre-bearing fertilization and other in Bearing plants fouryears-old. In the following year, the both experiments the nutrient sources were applied by band placement. The doses used were 0, 750, 1500 and 2250 g plant?¹ of wood ash and 0, 5 and 10 kg plant?¹ of cattle manure, constituting a factorial scheme 4x3, with 12 treatments and five replications. In the trial from Pre-bearing age, it was evaluated the cv. Isabella during two years, taking the following measures of plant growth: diameter and length of canes, trunk diameter and leaf area index (only in the second year). There was effect of treatments for all evaluated variables, with distinction to the leaf area index, that showed positive influence of increasing doses of wood ash and cattle manure. In the experiment of bearing plants fertilization, it was evaluated the grapevines cv. Ives, also by two years, measuring diameter and the length of canes, trunk diameter, leaf area index, yield, mean cluster weight and cluster number per plant. During two years, it was verified positive effect of the nutrient sources, mainly with the doses of 5 and 10 kg?¹ of cattle manure and 750 and 1500 kg?¹ of wood ash. In general, the combination of 5 kg?¹ of cattle manure and 1,500 g?¹ of wood ash was showed similar results as the higher dose of cattle manure at 10 kg?¹ per plant. It is possible to conclude that both nutrient sources could be uses to supply nutritional needs of American grapevine plants growth by organic system. |
