In the years 2015-2016 in Sahryń (50°41′ N, 23°47’ E) a field experiment, with the aim of assessing profitability of foliar nutrition of sugar beet with silicon, was carried out. The following products containing silicon were used in the experiment: Actisil, Herbagreen Z20 and Optysil. Each of them was applied once, twice and thrice. For each combination, the gross production value, the costs of foliar nutrition, the net production value and the profitability index were calculated. The total costs of silicon foliar application varied depending on the number of treatments and the applied product from 50 to 402 PLN/ha. The gross production value of sugar beet due to foliar nutrition with silicon increased by 1.3-22.9% for the research period, and the net production value by 5.5-19.0%. A large variation in the achieved financial results was observed in 2015, in which there were particularly unfavorable conditions for the growth and yield of sugar beet. In the more favorable year for growing sugar beet (2016), the difference was smaller. The largest increase in the gross and net production value of sugar beet was ensured by the double and triple application of Actisil fertilizer and the triple application of the Optysil growth stimulator. However, the largest profitability indicator (11.26) was characterized by a single Optysil growth stimulator application.

According to the World Health Organization, consumption of table salt (being a major carrier of iodine in human diet) should be reduced of 50%. Vegetables biofortified with iodine can become an alternative source of this element for humans. Agronomic recommendations with reference to biofortification have to be developed, including the evaluation of side-effects associated with iodine application to plants. Iodine is not an essential element for plants and hence its effect on crops has not yet been diagnosed. The aim of the study has been to assess the influence of soil fertilization with KI and foliar application of KIO3 on the success of iodine biofortification as well as the mineral composition of lettuce. Lettuce cv. Melodion F1 was cultivated in a field experiment in 2008-2009. Combinations with different soil fertilization and foliar nutrition with iodine were distinguished in the research including: control (without iodine application), three combinations with presowing soil fertilization of iodine (in the form of KI) in doses of 0.5, 1.0 and 2.0 kg I ha–1 as well three combinations with four applications of foliar nutrition with iodine solution (as KIO3) in the concentration of: 0.0005%, 0.005% and 0.05% after using 1000 dm3 of working solution per 1 ha so that the following amounts of iodine were applied: 0.02, 0.2 and 2.0 kg I ha–1, respectively. In lettuce heads, the iodine content as well as the content of: P, K, Mg, Ca, S, Na, B, Cu, Fe, Mn, Zn, Mo, Al, Cd and Pb were determined using the ICP-OES technique, while N-total was assayed by Kjeldahl method. In comparison to the control, only foliar nutrition with 0.05% solution of iodine significantly improved accumulation of this element in lettuce. At the same time, a lower level of nitrogen nutrition was observed in plants from this combination. A significant increase in the N-total content was found only in lettuce plants fed with 2.0 kg I ha–1 dose of KI. In reference to the control, both foliar and soil application of iodine contributed to a higher content of K, Mg, Ca, Mn and Cd as well as a decreased level of P, Cu and Zn in lettuce. Doses, forms and application methods of iodine were found to have produced diverse effects on the content of S, Na, B, Fe, Mo, Al and Pb in lettuce plants.

In a pot experiment conducted in a phytotron, the effectiveness of foliar nutrition of spinach (Spinacia oleracea L.) with different magnesium salts with and without the addition of 0.5% CO(NH2)2 was studied. Magnesium was applied 3 times in the form of solutions of MgSO4 x 7H2O, Mg(NO3)2 x 6H2O, MgCl2 x 6H2O, C4H6O4Mg x 4H2O, compared to water as the control treatment. The obtained results showed that foliar feeding of spinach with inorganic magnesium salts was an efficient method for supplementing the Mg level in plants during the growing period. But the application of a metalo-organic complex in the form of magnesium acetate (C4H6O4Mg x 4H2O) at a concentration of 1.7%, in spite of a similar effect on leaf Mg content, induced phytotoxic symptoms in the form of chlorotic and necrotic spots on the leaves. The application of the solutions of inorganic magnesium salts had a significant effect, resulting in more intensive leaf gas exchange (stomatal conductance, transpiration and photosynthesis) and an increase in leaf yield. Magnesium sulphate affected the abovementioned processes in the most effective way, while magnesium acetate had a negative impact. Foliar feeding of spinach with the magnesium salts resulted in an increased leaf content of protein, chlorophyll, carotenoids, nitrates and proline, but a decrease in vitamin C content. The addition of urea to the applied magnesium salt solutions increased the plant gas exchange rates and the leaf content of protein, chlorophyll, carotenoids, nitrates and proline, but it decreased the content of vitamin C, potassium and magnesium.

Salt stress is known as one of the most severe abiotic factors limiting the plant production all over the world. In this study, three additives: (i) supplemental Ca (5 mmol L–1) to nutrient solution, (ii) foliar application of micronutrients (Fe, Mn and Zn at 60, 160 and 110 mg L–1, respectively), and (iii) combination of both of them were evaluated aiming to reduce the negative impact of salt stress on tomato plants cultivated in a soilless culture and improve the internal quality of fruits. The obtained results show that salinity reduced vegetative growth and physiological parameters, fruit yield and its components, and even more lowered fruit market classification of tomatoes. Salinity treatment reduced most of essential macro- and micronutrients in tomato fruit, whilst Na content was increased. Tomato productivity and fruit quality were ameliorated under saline conditions by increasing Ca into nutrient solution and applying a foliar application of micronutrients. A combination of both additives ranked the first to alleviate the adverse effects of salinity on tomatoes, followed by solo supplemental Ca into saline nutrient solution. On the other hand, the internal fruit quality of antioxidant compounds, such as vitamin C, lycopene, α-carotene, β-carotene and lutein as well as acidity, total soluble solid and dry matter percent, were increased under saline conditions.

The aim of this research was to determine the influence of various forms, diverse doses, and methods of application of nitrogen fertilizers and foliar nutrition on the concentration of soluble sugars, ascorbic acid and phenolic compounds in cabbage. The three year (2005–2007) field experiment was carried out with ‘Galaxy’ F1 white cabbage. Two factors were examined: the type of N fertilizer ammonium sulphate and RSM (solution ammonium nitrate and urea 1 : 1), and method of N application (placement and top dressing – broadcasted with or without foliar nutrition). Climatic conditions considerably affect the concentration of compounds in cabbage. The highest concentration of soluble sugars was fund in cabbage receiving N as RSM in comparison to ammonium sulphate and with foliar nutrition treatment. In each year of the experiment plants fed RSM were characterized highest concentration of ascorbic acid. For means of year 2005–2007 foliar nutrition led to a marked decline in the concentration of ascorbic acid in cabbage. In 2005 and 2007 highest concentration of phenolic compounds was assessed in cabbage plants fed RSM. Cabbage plants fertilized 75% N broadcasted at planting of seedlings with foliar nutrition characterized the lowest concentration of phenolic compounds – means for 2005–2007.

Hyacinthoides hispanica (Mill.) Rothm. is a valuable bulbous ornamental plant grown in parks and gardens. It comes from the Iberian Peninsula, hence its cultivation under Polish conditions may be inefficient. The purpose of the study was to determine the effect of growing conditions and foliar feeding using phosphorous fertilizer on the growth and decorative qualities of H. hispanica. It was found that the pine bark layer effectively protected the plants from freezing, which had a beneficial effect on their growth and flowering characteristics. Flowering of plants grown without the mulch was minimal, which clearly indicates that mulching of the soil under H. hispanica can be necessary. Plants grown using the mulch produced more and longer leaves, and also formed more inflorescences and fruits as well as longer inflorescence stems. The addition of peat to the soil did not favour the growth and decorative qualities of H. hispanica, while foliar nutrition with phosphorous had a positive effect. In addition, the decorative values of H. hispanica were influenced by the interaction of soil mulching with bark and foliar feeding. Plants grown in this combination had more inflorescences, which were higher, composed of more flowers in the inflorescence and reached a greater diameter than non-fertilized ones. Tested cultivars of H. hispanica differed in their features of growth and flowering.

W latach 2012-2014 przeprowadzono ścisłe doświadczenie polowe w Wydziałowej Stacji Doświadczalnej Uniwersytetu Rzeszowskiego w Krasnem koło Rzeszowa. Celem badań było określenie reakcji pszenicy jarej na zróżnicowane nawożenie azotowe (80 i 120 kg N·ha–1) oraz dokarmianie dolistne (Plonvit zboża). Doświadczenie założono na glebie brunatnej wytworzonej z lessu, zaliczanej do klasy bonitacyjnej IIIa, kompleksu pszennego dobrego. Zmienne w latach badań warunki pogodowe wywarły duży wpływ na plonowanie pszenicy jarej. Na podstawie uzyskanych wyników stwierdzono, że wyższa dawka azotu w porównaniu do niższej wpłynęła na istotne zwiększenie indeksu powierzchni liści (LAI) oraz wskaźnika zieloności liścia (SPAD). Średni kąt nachylenia liści (MTA) wyniósł 49,5° i nie był istotnie zróżnicowany. Wyższe nawożenie azotowe wpłynęło również na istotny wzrost liczby kłosów na jednostce powierzchni, wylegania roślin, MTZ, celności ziarna oraz plonu ziarna w odniesieniu do dawki niższej. Dokarmianie dolistne skutkowało istotnym zwiększeniem takich parametrów jak wskaźnik SPAD, MTZ oraz plon ziarna w porównaniu do obiektu kontrolnego. Zastosowane nawozy zmodyfikowały skład chemiczny ziarna. Zwiększona dawka azotu podwyższyła w ziarnie zawartość białka ogólnego, zaś obniżyła włókna surowego. Z kolei dokarmianie dolistne skutkowało wzrostem zawartości popiołu w ziarnie w porównaniu do kontroli.

An experiment was established to evaluate an effect of foliar application of Florovit and Ekolist-Warzywa+Urea on the yield level and quality of six large-fruit melon cultivars (Pacstart, Yupi, Seledyn, Polydor II, Gattopardo, Legend) cultivated in the filed under the climatic conditions of central-eastern Poland. A higher yield of better quality was achieved in the years with relatively high air temperature and low rainfall in August when melon finishes to grow. Florovit-fertilized plants produced higher marketable yield and a higher number of marketable fruit than non-fertilized plants. Foliar feeding with both formulations investigated significantly increased the average fruit weight, flesh thickness and fruit flavour as compared to the non-fertilized melons. The cultivar ‘Yupi’ produced the highest marketable yield and the greatest number of marketable fruit whereas ‘Seledyn’ was characterized by the highest average fruit weight. ‘Gattopardo’ cultivated without foliar feeding and ‘Yupi’ and ‘Gattopardo’ fertilized with Florovit and Ekolist+Urea produced the best fruit in terms of their flavour.

In the years 2006–2007 radish ‘Opolanka’ cv. was grown in 60 × 40 × 20 cm containers, placed in the open field under a shade providing fabric. A loamy clay soil was used as a substrate. The following foliar nutrition treatments were applied twice: 1 – control (spray with water), 2 – urea, 3 – urea + Mo, 4 – urea + Mo + BA, 5 – urea + Mo + BA + sucrose, 6 – BA (benzyladenine) and 7 – sucrose. There were used the following concentrations of tested compounds: urea 20 g∙dm⁻³, sucrose 10 g∙dm⁻³, molybdenum (Mo) 1 mg∙dm⁻³ and BA 5 mg∙dm⁻³. Foliar nutrition treatments had a significant effect on average mass of plant leaves and on concentration of soluble sugars and ascorbic acid in radish roots. Plants treated with a mixture of urea + Mo + BA + sucrose featured the highest average mass of plant leaves. Radish roots of control plants and those sprayed solely with BA contained significantly more soluble sugars than roots of plants from other treatments. Spraying the plants with solutions containing only sucrose or only BA (treatments: 6 and 7) caused a significant reduction of ascorbic acid content in radish roots in comparison to other treatments. All the solutions used for foliar nutrition had no effect on radish roots mass and on mass of whole plants (roots + leaves). There were also not observed any significant changes in dry matter content of leaves and roots likewise in the content of phenolic compounds, phenylpropanoids, flavonols or anthocyanins in radish roots.
