ABSTRACT

Fertilization can influence the production and must composition of vine. Hence, the purpose of this study was to evaluate the effects of organic and nitrogen fertilizer on the yield of drip irrigated wine grape ‘Syrah’ and on the must composition, in three growing seasons (April to August 2010; November 2010 to February 2011; May to September2011) in Petrolina, State of Pernambuco, Brazil. The treatments consisted of 2 organic fertilizer levels (0 and 30 m3 ha-1 of goat manure) and 5 N levels (0, 10, 20, 40 and 80 kg ha-1), in 5 randomized blocks in split-plot design. The organic fertilization increased the soil organic matter content, the available P, and CEC, as well as decreased the total tritatable acidity in the must in the 1st growing season and increased the yield and the hundred berries weight in the 3rd growing season. The N rates did not influence the number of cluster per plant, neither the fruit yield and enological characteristics.
