The study came as the result of a test in the Agricultural Institute of Kosovo, where the best cultivars were chosen as far as the production and other vital parameters are concerned.
1. Improvement of potato cultivation technology
- Implementation of the cultivars of special interest for the agro-climatic and production conditions in Kosovo.
- Regarding their compatibility for consumption and further elaboration and their resistance to the harming factors.
The influence of P, K in production and some qualitative parameters of potato.
This study aims not only at the evaluation of potato cultivars in general, but also at the identification of all the indicators of a cultivar in particular and in a detailed way, based on the experience of developed countries with high production rates in this fields, such as Netherlands, Germany, France, etc. Through the study and specialised literature the evaluation and the relation between them is undertaken.
Based on the resistance of the cultivars to various illnesses, the elimination of the pesticides is done. This leans towards the organic, agriculture perspective and the possibility of increasing the potato cultivation in our country.
The identification of the vegetation periods, the shape, the skin colour, the pulp, and many positive indicators open ahead new perspectives.
The study of the dry material content enabled the division and compatibility of the cultivars for consumption and industrial elaboration. .
Another aspect of the study is the evaluation of the cultivars regarding the indicators mentioned above for a three year period which provides the stability of the production indicators influenced by the climatic factors and this is based on statistical data.
- 1. Materials and method
The field observations are carried out in two agro-ecologic regions of Kosovo:
- In Arbnesh, in the farm of the Agricultural Institution of Kosovo in Pejë (Rrafshi i Dukagjinit) and
- In Pestovë (Rrafshi i Kosovës).
There are included 11 potato cultivars for fresh consumption and industrial elaboration : Sinora, Faluka, Ambition, Arnova, Zafira, Exelent, Mantiou, Rudolph, Marlen, Ambasador and Kondor. The seed was of high quality, A class, imported from Netherlands (AGRICO). The fields were planted in four repeated tiers according to the plan system (PPRB) in block, with 4 rows for each cultivar. The surface of each plot of land is 12m2 , while for the variant is 48m2.
The main digging was done in Autumn 2010, while the exploitation of the surfaces was done in Spring 2011. Pre-culture in Pestovë used to be the corn and in Pejë, the wheat. The fundamental fertilizing was done with fertilizers, type NPK, ( 15:15:15), in Spring with 1000 kg/ha. The planting was done manually: 21 – 22.04. 2011 Pestovë, Pejë.
The re-fertilisation is done during the pre-flourishing with NAG (27%N) and quantity 200 kg/ha. The extraction was done on 01.10.2011in Peje, respectively on 26.10.2011 në Pestovë.
Herbicides that were used : Glifosat (in autumn total herbicide), Senkor 1kg/ha (before flourishing) and irrigation was done on 30 May, 15 June and 05 July 2011. During the vegetation the plants are protected from illnesses, harmful factors, etc. Insecticides used are Foksin (25kg/ha) and Mospillan (40gr/ha), while the fungicides : Ridomil MZ 42 (2kg/ha), Ridomil MZ 68 (2.5kg/ha).
