Soil Tillage

The in-row and inter-row soil tillage is the main operation during the winter, repeated up to 8 times a year for rain water storage, weed control and airation. Conventional ploughs, discharrows, rotary tillers and tineharrows, subsoilers are the most used equipments for soil cultivation. Soil tillage is the most costly operation because of improper machinery and multiple passes.

Pruning There are some differences between the pruning methods in according to production targets and the quality of grapes depend on also pruning efficiency besides other influential factors. Generally hand devices such as knives, scissors and saws are used. This method is simple but is not economic and ergonomic.

In last years there is a tendence for electrical-pneumatic-automatic devices for this purpose. They increase the work capacity app. 40 %.

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

Self propelled machines and high-tech pruning methods are only suitable for new wine grape plantations and there are few examples in Turkey. First calculations on pruning expences per area show a decrease about 30-50%, although the purchase price of such system-tractors are rather high.

Pruning

The pruning waste is not prefered to be mixed with soil because of bacterial disease danger. Generally this waste is removed with special rakes and trailers.

Fertilization

Only in one year fertilizer prices are doubled or even trippled in Turkey. For that reason, distribution of plant nutrients are much more important than ever before.

As the performance of surface spreaders are not sufficient and not ideal for homogeneus distribution, undersoil fertilization must be prefered. This machine is much more efficient and saves about 30% fertilizer, although the time requirement is little higher.

Fertilization

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

Generally in small vineyards, hand and snapneck pulverizators are used, wheras mainly tractor mounted or trailed machines prefered in larger areas.

Plant Protection

Under the unsuitable conditions, sprayed chemicals do not reach the target surface but pollute air and soil along with economic and ecologic problems.

Spraying costs can be reduced up to 60 % with assistance of appropriate design, construction, nozzle type, air velocity and operation pressure.

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

Special purpose side spraying, or system-tractors and their spraying attachments are not in use, except a few new established vineyards for wine production.

Irrigation

The efficiency of irrigation and total costs depend on;•Water source•Irrigation method•Irrigation area

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

Border irrigation needs much more water, manpower, time and as a result higher cost.

Although higher capital demand at the beginning, the water and energy costs of drip irrigation are approximately 20-40% lower.

Moreover this system can be used for fertilization.

HarvestingAll vineyards in the region are harvested manually.

Such rear boxes reduce in-farm transport costs up to 40%, compared to hand-baskets.

The vineyards are mostly optimal preperad for harvest operations, but sometimes such unusual bed examples can be seen.

Harvesting

For raisin production, the next steps are dipping and drying in open air before industrial manipulations. Also these steps are done manually.

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

Harvesting

The high-tech in harvesting with various methods have just been introduced to Turkey. Althougt the existed vineyards are not suitable for such solutions, new wine grape farms are interested with these, while the real “Kilogram” or “Hectare” costs are calculated 20-40% lower and can be harvested just in time.

GÜCÜYEN, Dept. of Agricultural Machinery, Ege University, İzmir-Turkey

CONCULUSION Estimated costs and investment analysis related to the production of grapes highly depend on different single cases. The main bottle-necks in Turkey for higher productivity and lower unit costs are;

•Farm sizes are too small,

•Farm areas have fragmented structure,

•Vine shapes are varying and they have different systems,

•In-row and inter-row spaces are variying too much,

•Financal instruments for the small-scale farms are limited,

which make mechanization really difficult if not impossible. But it must be seen all these discussions are not only for todays questions, but especially for new vineyards of tomorrow, so that we will not have the same problems in the future.
