The study was conducted over the years 2004–2006 in experimental plots located in Bałcyny. A multi-purpose, late potato cultivar, Jasia, was grown. The experimental factors were as follows: I – mineral fertilization levels: A (N – 80 kg ha⁻¹, P – 80 kg ha⁻¹, K – 120 kg ha⁻¹), B (N – 120 kg ha⁻¹, P – 144 kg ha⁻¹, K – 156 kg ha⁻¹), II – foliar fertilization: 1 (Basfoliar 12-4-6 – 8 dm³ ha⁻¹), 2 (ADOB Mn – 4 dm³ ha⁻¹), 3 (Solubor DF – 2 dm³ ha⁻¹), 4 (ADOB Mn – 2 dm³ ha⁻¹ + Basfoliar 12-4-6 – 4 dm³ ha⁻¹), 5 (ADOB Mn – 2 dm³ ha⁻¹ + Solubor DF – 1 dm³ ha⁻¹), 6 (Basfoliar 12-4-6 – 4 dm³ ha⁻¹ + Solubor DF – 1 dm³ ha⁻¹), 7 (Basfoliar 12-4-6 – 2.7 dm³ ha⁻¹+ADOBMn – 1.3 dm³ ha⁻¹+SoluborDF – 0.7 dm³ ha⁻¹), 8 (control treatment without foliar fertilization). The health status of potato tubers was studied after five-month storage. The rates of tuber infection by Streptomyces scabies and Rhizoctonia solani were estimated on 100 tubers selected randomly of particular treatments, according to a nine-point scale, and were presented as a percentage infection index. The symptoms of soft rot (Pectobacterium carotovorum subsp. carotovorum), late blight (Phytophthora infestans) and dry rot (Fusarium spp.) were evaluated in 5 kg samples for each treatment. The results were expressed as a percentage of the mass of infected tubers. Foliar fertilization and the levels of mineral fertilization NPK did not affect the severity of common scab symptoms. Significantly higher rates of infection by R. solani were observed in tubers from the control treatment without foliar fertilization and from the treatment with a lower level of mineral fertilization (A). The symptoms of soft rot (4.6% of the mass of infected tubers) and late blight (1.3%) were strongest in 2006, while the symptoms of dry rot (2.7%) – in 2005. The severity of diseases caused by the above pathogens was greater in tubers grown in plots with a higher level of mineral fertilization (B) – N 120 kg ha⁻¹, P 144 kg ha⁻¹, K 156 kg ha⁻¹ (1.3 to 4.1% of the mass of infected tubers) than in tubers grown in plots with a lower level of mineral fertilization (A) –N80 kg ha⁻¹, P 80 kg ha⁻¹, K 120 kg ha⁻¹, (0.8 to 3%). The combined application of foliar fertilizers reduced the percentage mass of tubers infected by P. carotovorum subsp. carotovorum and P. infestans to the highest degree.

The effect of three foliar-applied Ca-containing preparations on the anatomical features of leaves of sweet pepper (Capsicum annuum L.) was studied. The following preparations were used: Ca(NO3)2, Librel Ca and Wapnowit, applied at the respective concentrations of 0.5%, 1%, 1%, which corresponded to a content of 2000 mg Ca 􀂉 dm-3. Light and scanning electron microscopy were used in the study. It was demonstrated that in amphistomatic bifacial pepper leaves numerous specialised cells occurred which accumulated calcium oxalate crystals in the form of crystalline sand. Anisocytic stomata were found with a much greater density in the abaxial epidermis. They were characterized by very well-developed outer cuticular ledges. It was found that in the leaves of the plants sprayed with the nutrient supplements with increased Ca content there was a much smaller number of epidermal cells per 1 mm2 than in the control plants. These cells were distinguished by an increased size. In the case of the application of the nutrient supplements Librel Ca and Wapnowit, the number of stomata also decreased. However, the application of the calcium supplements resulted in an increase in the value of the stomatal index compared to the control, which is attributable to a significant reduction in the number of epidermal cells not belonging to the stomata. The plants additionally supplied with Ca were marked by a larger number of colenchyma layers and an increased volume of leaf parenchyma cells. In the case of pepper leaves, the thin cuticle and the outer cell wall are not a major barrier to the Ca-containing preparations applied for spray treatment. Nevertheless, the decrease in the number of stomata may restrict the possibility of Ca uptake by this way, which compensates the increase in surface area of particular epidermal cells that will be the main way of Ca penetration into the internal leaf tissues.

Yields of oilseed rape harvested by farmers in Poland are usually much below the attainable potential of currently cultivated varieties, mainly because of the insufficient supply of nutrients during the yield foundation period, which determines the final number of secondary branches. This situation is typical of whole Poland, but may take place even on farms where high yields are harvested, for example in 2007. In 2006, 2007 and 2008, the year effect of multi-micronutrient fertilizers on yield of seeds, elements of yield structure and macronutrient content was studied. Multi-micronutrient fertilizers were applied twice over oilseed rape foliage during its pre-anthesis growth (BBCH45 and 53). In 2007, due to a drought in April, the harvested yields of seeds were below the country’s average. However, in each year of the study, a significant increase in the seed yield owing to the foliar application of multi-micronutrient fertilizers was found. The increase in the yield of seeds, averaged for the three years, reached 0.486 t ha–1 for the NPK+MiMo treatment (full set of micronutrients) and 0.36 t ha–1 for the NPK + Mi treatment (without molybdenum). The increments of the oilseed rape yield resulted from an increased number of developed secondary branches. This yield-forming element was an indirect result of the application of multi-micronutrient fertilizers, which affected the nitrogen economy by oilseed rape plants during the foundation period of their growth. At the same time, the increase in seed yield was significantly modified by the total number of developed pods, which is shaped during the yield-forming period of oilseed rape crop growth. Under conditions of the study, the magnesium content in secondary branches was found to be an element significantly correcting their number, thus increasing the yield of seeds.

The experiment with ‘Boro F1’ red beet was aimed at determining the effect of the kind of nitrogen fertilizer (RSM, ENTEC 26) and the manner of application (broadcasting/liquid spreading, with / without foliar nutrition) on the content of protein nitrogen in roots, and ammonium and nitrate nitrogen content in leaves and roots of red beet. The kind of applied fertilizer did not have any influence on the size of examined parameters. In 2005 foliar nutrition with nitrogen caused a decline in nitrate concentrations in leaves and roots of the plants in comparison with unnourished objects; however, such correlation was not corroborated in the following years of the cultivation. Quantities of all examined parameters were diversified depending on the cultivation year.

Microelements play an important role in the production of horticultural plant seeds. A great attention was devoted to titanium, which according to the literature, accelerates germination of pollen grain, thereby increasing the yield of fruit and seeds as well as improves the health status and quality of seeds. The research was carried out to determine the effect of Tytanit containing 0.85% of titanium applied at different stages of onion plant development on the yield and quality of the obtained seeds. The research was conducted in 2003-2005 in the field of Research Institute of Vegetable Crops and Research Institute of Pomology and Floriculture. The experiments were designed in three randomized blocks, in three repetitions and with three onion cultivars: Sochaczewska, Supra and Błońska. Tytanit was applied before sowing (during seed soaking) or during vegetation period as a foliar spray from the beginning of flowering till the seed harvest at the concentration of 0.04% - 600 dm3 water∙ha-1. The treatments were performed at three different stages of plant development, every 7-10 days. Independently of the stage of plant development, the application of Tytanit significantly increased the yield of onion seeds of all the examined cultivars. The highest onion seed yield was obtained after spraying plants with this chemical during full flowering. Similarly, foliar application of Tytanit during full flowering of onion plants significantly improved the quality of seeds. This chemical also significantly increased the weight of 1000 seeds as well as their germination in all the examined cultivars in comparison with the control. The onion seeds obtained after the application of Tytanit during full flowering are characterized by better health status.

The present study, carried out in the period 2007-2009 in the Sandomierz Upland, did not show a significant effect of foliar fertilization on trunk thickness and canopy volume in the cultivar Łutówka. However, under the influence of urea applied three times in combination with Florovit at a concentration of 0.5%, a clear increasing trend was observed in the above mentioned parameters used to assess the strength of growth. In years of abundant fruiting, this study showed a significant increase, or on the verge of significance, in yield after threefold application of urea and Florovit in combination. A small insignificant effect of fertilization on fruit weight shows that the growth in yield after the application of fertilization was produced as a consequential effect of a significant increase in the length of one-year shoots and thereby in flowering intensity of the ‘Łutówka’ cherry trees. In the case of the sour cherry cultivar Łutówka bearing fruit on one-year shoots, foliar feeding after flowering using multi-nutrient fertilizers and urea can be recommended as a technological treatment, in particular in years of abundant fruiting.

The paper presents the results of a three-year exact experiment conducted in Bałcyny, in which a late potato cultivar, Jasia, was grown. The objective of the study was to determine the effect of different levels of mineral fertilization: A (N 80 kg 􀂉 ha-1 P 80 kg 􀂉 ha-1 K120 kg 􀂉 ha-1) and B (N 120 kg 􀂉 ha-1 P 144 kg 􀂉 ha-1 K156 kg 􀂉 ha-1), and foliar fertilization (Basfoliar 12-4-6, ADOB Mn and Solubor DF) on the quantitative and qualitative composition of fungal populations colonizing potato tubers. Fungi were isolated immediately after harvest and after a five-month storage period. After seven days of incubation, fungal colonies were transferred onto agar slants for microscopic identification. Over the entire experimental period, more pathogenic fungi were obtained from potato tubers analyzed after storage (62.9% of the total fungal population after storage) than from those analyzed immediately after harvest (39.1%), and the greatest number of fungi was reported in 2004. Rhizoctonia solani was isolated most frequently, followed by Colletotrichum coccodes and Alternaria alternata. Pathogens of the genus Fusarium and the species Helminthosporium solani were not numerous. In the treatment A with soil mineral fertilization with lower NPK rates, larger numbers of pathogenic fungi were noted in 2004 after harvest and after five-month storage, and in 2005 after harvest. At the remaining dates of analysis, pathogens were more frequently isolated from potato tubers in experimental variant B with higher NPK rates. Immediately after harvest, the highest number of pathogenic fungi was isolated in the treatment with foliar application of ADOB Mn and Basfoliar 12-4-6. After five-month storage, pathogens most often colonized potato tubers in experimental variant B with foliar application of Solubor DF, Solubor DF and ADOB Mn, and in experimental variant A with a combination of fertilizers. In the other fertilization variants, including in the control treatment, the population size of pathogenic agents remained at a similar level.

The nutritive value and wholesomeness of carrot are highly appreciated owing to such biologically active compounds as carotenoids, vitamin C and mineral compounds found in its roots. In 2007-2009, field experiments were performed on the effect of foliar fertilisation of carrot with magnesium sulphate during its vegetative growth on selected nutrients (total carotenoids, vitamin C, mineral magnesium). The field experiment was set up in a splitplot design with three replications on light soil, of slightly acid reaction, low in available P and K forms and very low in Mg. Magnesium was applied in rates of 0, 45 and 90 kg MgO ha–1 by spraying carrot plants with a 3% solution during their intensive growth in the vegetative season, accompanied by constant N, P, K fertilisation. The experiment involved five carrot cultivars: medium-late Berjo, and late Flacoro, Karotan, Koral and Perfekcja, all characterized by good storage life. The content of selected nutrients in carrot roots was determined immediately after harvest and after six-month storage in a traditional earthen mound. Foliar application of magnesium significantly increased the nutritive value of roots of the carrot cultivars after harvest, raising the content of total carotenoids, vitamin C and magnesium in edible parts. The rate of 45 kg MgO ha–1 was most favourable. The sixmonth root storage led to a decrease in the biologically active compounds. The recorded loss (mean for cultivars and fertilisation) reached 20% of carotenoids, 50% of vitamin C and 1% of magnesium. The highest nutritive value was determined for roots of the cultivars Karotan and Perfekcja and the lowest one in roots of cv. Flacoro.
