Learning outcomes

The course presents the different growing techniques in viticulture, examines the problems and effects on productivity and quality. In particular, the course examines how plant the vineyard, the different forms of vine training and pruning systems, techniques of soil management of vineyards, the techniques of irrigation, the mineral nutrition of the grapevine, particular reference to the systems of fertilization to soil and foliar, the canopy management and methods of harvest.

Program

Lectures (5 CFU). The course of viticulture practices provides a part of lectures in which are discussed the various issues that concern the operational choices and procedures for the execution of the agronomic techniques in the vineyard. The course initially presents ways to develop a sustainable viticulture. It considers how to implant the vineyard. In fact the design and subsequent plant operations are of crucial importance for the success of a vineyard in time and to do this we must start from the choice of the site that provides a perfect knowledge of the ecological factors taken into consideration by evaluating the characteristics of the land, upon the position, exposure and slope, depth, texture and soil structure, in addition to the chemical composition. These concepts follows the treatment of soil preparation: leveling and excavation; burglary; refinement of the terrain. The discussion follows with a description of the systems drained and fertilizing bottom preimplantation. Also presented are the various provisions of the rows (rittochino, cavalcapoggio, Girapoggio, variable geometry), because the adoption of certain plant density. These arguments follow those relating to the choice of material for propagation of the vine (variety and rootstocks), methods for plants, materials for the construction of the vineyard. Other topics covered during the course are pruning (agronomic and physiological foundations), the concepts of minimal pruning and crotchet, the forms of vine training (Gobelet, Guyot, Cordon, Sylvoz, Casarsa, free cordon, cordon free mobilized, Pergolas, System rays or Bellussi, Parrales, GDC, Lyra). The course continues with a discussion of how soil management (machining, chemical weed control, controlled grassing), presents methods for practicing the irrigation of vineyards and fertilization. Then goes on to deal with the microclimate of the vineyard induced by different types of curtain of leaves, interventions to green during the growing season of the vine (flaking, suckering, topping, bunch thinning). The course ends with the presentation of the harvest mode according to the type of grape maturation reached (technological, phenolic, aromatic, etc.).
Tutorials (1CFU): practical exercises are carried out in the vineyard and in relation to the time in which phenological are held, we discuss the various aspects of plant-growing, cultivation techniques applied and the reasonableness or otherwise of the operations performed.
Teaching material: notes provided by the teacher at the beginning of the course and reference books.

Examination Methods

Final exam is oral for both students attending and non-attending and aims to verify the knowledge of the subjects analyzed during the course.
The oral examination will focus on the topics covered in the lesson (available in the teaching materials distributed and in the reference texts). The student's preparation will be assessed on the basis of: (i) knowledge and in-depth study of the topics dealt with; (ii) exhibition capacity; (iii) correctness of technical-scientific language.
