It is a highly porous material that is currently used as dsiennik soil improvement agent. As part of the research, an attempt was made to use biocarbon as a usstaw of a greenhouse cucumber growing medium.

For cucumber growin biochar blend with perlite was used. The control medium was mineral wool, which is commonly used in greenhouse cucumber cultivation. Based on the results of the research, the biocarbon-based substrate with perlite ushaw used to grow greenhouse cucumber. Cucumber yield was higher than on rockwool. The quality of fruit grown on a pkz.2181 substrate is similar to that of mineral wool. The content of mineral components in fruit from biocarbon substrate was lower compared to mineral wool.

Growing greenhouse cucumber on biocarbon substrate contributed to a significant reduction of nitrate accumulation in fruit. Natomiast Li i in. Wyniki analiz zestawiono w tabeli 2.

Summary Potato fertilization is an essential factor in the modern production technology as it determines the crop size, crop quality, 22003 chemical composition, starch content and the shelf life, as well as shaping the production viability for that species.

The compact two-level factorial field experiment involved analysing the impact of manure, litter and mineral on the yield of two varieties: The yield differed significantly depending on the variety. The general crop obtained for Tajfun was by 6. Crop size was also the outcome of the fertilization applied.

Litter and manure gave better results when combined with mineral fertilization. The largest crop was obtained for Tajfun following the application of litter in combination with mineral fertilization, while for Kuras following the application of manure in combination with mineral fertilization.

The fertilization methods influenced certain aspects of crop quality tuber size, as well as starch content.

Introduction Balanced supply of the required nutrients throughout the whole vegetation period is a prerequisite for obtaining considerable crops of satisfactory quality.


Potato fertilization is an essential factor in the modern production technology as it determines the crop size, crop quality, tuber chemical composition, starch content and the shelf life. Furthermore, fertilization determines the viability of all directions in potato production. According to literature, to achieve a crop level of 40 t ha -1 potatoes take from the soil kg of potassium, kg of nitrogen, 60 kg of phosphorus, 45 kg of calcium, 25 kg of magnesium, as well as small quantities of zinc, manganese, sulphur, boron, copper and iron.

The mineral and organic substance of the soil is a natural source of nutrients. Another source that supplies macro- and microelements to soil comprises natural, organic and mineral fertilizers, without which potato Mineral and organic fertilization does not guarantee the accessibility of the components required to obtain considerable yield of satisfactory quality.

The development of potato, just like any other plant, involves periods characterised by high demand for nutrients critical periods. In that period it is essential to satisfy the demand of the plants for nutrients since any deficiencies may reduce the size of crop and compromise the quality of tubers.

Periodic deficits in supply of nutrients may manifest themselves in particular in varieties of a high yield potential as well as in highly productive plantations. Phosphorus accelerates the ripening of plants and it prevents diseases as well as mechanical damage to tubers, concurrently improving the shelf life. Potassium stimulates growth and helps increase the number of large tubers. Potassium also limits the darkening of the insides after cooking, increases the vitamin C content and improves the inside texture.

The most efficient and economical solution is to use multi-component fertilizers since they permit introducing NPK, and even Mg, to the soil simultaneously, thus ensuring good nutritional conditions for plants. Some multi-component fertilizers can be sown fully in autumn, while the rest must be supplemented with nitrogen.

The dose should depend on the current phosphorus, potassium and magnesium content in soil. The objective of the experiment was to determine the effects of natural fertilization with manure and litter in Materials and Methods The compact field experiment regarding the effects of fertilization on potato productivity was carried out in class IIIa soil representing the good wheat soil complex, in the Silesian Lowlands. The soil was characterised by average content of such nutrients as P 2 O mg g -1, K 2 O The two-level factorial field experiment was conducted according to the randomized block design in three repetitions.

It involved analysing the effects of natural fertilization with manure and chicken litter as well as the effects of the combination of manure and chicken litter with mineral NPK fertilization on the yield of two varieties: Tajfun edibleKuras starch variety.

In the year preceding vegetation, in the 3 rd decade of October, manure and litter was applied, at a dose of 30 t ha -1 and 20 t ha -1 respectively. The manure introduced N kg ha -1, 95 P kg ha -1 and K kg ha -1 kg to the soil, while the litter contributed N kg ha -1, P kg ha -1 and K kg ha Before the planting process, mineral multicomponent fertilizers were applied to introduce 63 N kg ha -1, 60 P kg ha -1 and K kg ha After the planting, another 45 N kg ha -1 was added.

Seed potatoes of mm in diameter were planted in the 2 nd decade of March, 25 cm apart, in rows 75 cm apart. The crops were harvested in the 1 st decade of October. The weather in the year of the studies is presented in Fig. May was characterised by the greatest precipitation of the whole vegetation season 70 mm more than required, while the figures from the said time frame are similar to the requirements.


The demands of potato when it comes to hydration are considerable, while the precipitation was The thermal conditions did not cause any clear disruptions and they were beneficial for potato vegetation.

Temperature and precipitation in vegetative season The crops were harvested from all the experimental fields and samples were taken to define the crop structure and starch content. The results were developed statistically using the analysis of variance and Tukey’s multiple comparison test.

Calculations were carried out in the SAS 9. Results and Discussion The studies have proven that the requirements of the varieties as well as natural fertilization and natural fertilization in combination with mineral fertilization significantly modified potato yield Fig.

The crop size of Tajfun was 6. Natural fertilization in combination with mineral fertilization clearly increased the crop size. Both manure and litter application resulted in crops about 8 t ha -1 smaller than those arising from the combination of natural and mineral fertilization Fig. The studies have demonstrated an interaction between the properties of the varieties and the fertilization applied.

For Tajfun, the combination of natural and mineral fertilization increased the crops by approximately 12 t ha -1, while for Kuras the value was around 5 t ha -1 Fig. In their studies they showed that separate application of either manure or mineral fertilization reduced the tuber crop size by Higher starch content characterised Kuras 3. Starch content was also modified depending on the fertilization form.

The highest starch content was obtained for fertilization with manure and litter only: On the other hand, application of natural fertilizers in combination with mineral fertilizers reduced the starch content. The combination of natural and mineral fertilization caused the starch content to drop by 0. In neither variety the applied natural fertilization forms led to any proven difference in starch content Fig. A significant interaction was observed in the studies between the varieties and the fertilization applied.

For Tajfun, mineral fertilization reduced the starch The effects of mineral fertilization on starch content was already observed by other researchers.

In their studies, Chmura et al.

In some varieties, such as Danusia, Wiking, Wigry, high nitrogen doses considerably reduced starch content. They did not cause any changes in the Wawrzyn and Wolfram varieties. The impact of foliar fertilization on starch content in potato tubers explanations as on Figure 2 The study also involved analysing the effects of fertilization on the size of tubers, including their percentage share in the crop, as well as the crop of the tubers representing particular fractions.

The size of tubers was modified depending on the variety genotype Fig. The biggest crop of tubers larger than 60 mm in diameter was obtained for Tajfun, and it was greater by 7 t dzirnnik -1 than for Kuras.
