The course has the goal to make students aware of processes of vineyard planting and of the grape production. The critical points and the importance of various factors contributing to the production chain will be highlighted.
Expected learning outcomes
The student acquires information on management and problems of production processes. The student also deepens the practical aspects and the changes induced on grape and wine by the various interventions on the plant.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
1 ° CFU The planting of the vineyard. General aspects: Production philosophy, legal obligations and authorizations, economic choices. Genetic choices: Criteria for choosing the grape variety, clone and rootstock. Crop choices: soil elaboration: stabilization works (leveling, drainage and superficial viability); Soil preparation: break-in and pre-planting operations; Fertilization: soil analysis evaluation, choice criterias, types, intervention period; Execution of the planting: Plant tracing and planting techniques. Vineyard support structures and materials 2 ° CFU Vine growing propagation materials (rootstocks and varieties). Environmental characteristics of viticultural nursery. Types of propagation (gamic and agamic). Commercial nursery, production processes (grafted vine, rooted cuttings). Viticultural nursery certification, nursery regulations. Irrigation: General aspects: evaluation of the availability and philosophy of water use in viticulture. Techniques, limitations and needs. Periods of irrigation and effects on the production and quality of wine. 3 ° CFU Training systems. Characterization and description of the main forms of vine cultivation used in Italy. Evolution and objectives of training systems. Evolution of vineyard mechanization, possibilities and limits of mechanization in different environments. Evaluation of gem numbers, pruning types. Periods and methods of intervention. Effects on the production and quality of grapes and wine. Plant density: Historical evolution of the sixth plant. Factors that influence the choice in relation to the training system and other agronomic aspects related to the environment and the enological choices. Problems with the distances "on" and "between" the rows. Effects on the production and quality of grapes and wine. 4 ° CFU Soil Assessment Strategies. The main types of strategies: tillage, cover crop, weed control. Effects on the environment and on soil characteristics. Management strategies and integrated forms related to environmental characteristics and to the oenological choice. Objectives and effects on the vegetative-productive balance of the vine and the quality of the wine. Vineyard fertilization: Requirements in plant nutrients. Evaluation of environmental, viticultural and oenological variables for the implementation of fertilization. Types of fertilization, organic and mineral. Period of intervention and reflections on the vine and the quality of the grapes. 5 ° CFU Management of the crown Description of the green operations. Criteria and moments of implementation and intensity of interventions. Effects of various green interventions on the production and quality of grapes. 6th CFU Maturation and Harvest General Aspects: oenological objectives, varietal characteristics. Visual, analytical and sensorial elements in choosing the optimal moment. New directions in choosing the optimal moment, genetic strategies (genomics, metabolomics, proteomics). Harvesting method: evaluation of the periods and methods
