Recently, the importance of silicon (Si) has been demonstrated for many plant physiological processes. The recognized function of Si is to help plants to overcome multiple biotic and abiotic stresses, e.g. disease or pests, low temperature, water deficit, salinity or heavy metals. Silicon advantageously impact on plant development and may improve the quality of ornamental plants. Hosta is an ornamental perennial, that flowers can serve as a source of nectar and pollen for floral visitors. The effect of artificial silicon (Si) supply on flowering, nectar production and pollen traits in Hosta Tratt. ‘Krossa Regal’ was studied. A foliar spraying of 0, 120, 180 and 240 mg Si·dm–3 was applied with water solutions of Actisil Hydro Plus, containing silicon in the form of H4SiO4. Silicon supply in concentration of 180 and 240 mg Si·dm-3 affected the morphometric traits of the flower (perianth width and floral tube length), but not the number of flowers produced per inflorescence. The silicon supply in concentration of 180 and 240 mg Si·dm-3 resulted in the increase of nectar production and in sugars excess in floral nectar. Treatments in concentration of 180 and 240 mg Si·dm-3 positively influence both pollen production and pollen viability. Presumably, most of these results can be explained through the effect of the Si on metabolism enhancement, e.g. by water balance regulation and increase in photosynthetic efficiency.

Five sugar beet cultivars and three levels of foliar treatments (control, Humix universal plus and Biafit Gold) were examined in the field trial without irrigation founded in the years 2005-2007 on experimental base of Slovak University of Agriculture in Nitra in Dolna Malanta. The influence of weather condition on all the observed parameters was statistically highly significant. The used bioactive leaf preparations increased root yield, digestion and refined sugar content. Biafit Gold had positive impact on root yield and Humix universal plus on digestion and refined sugar content (statistically not significant). Cultivar had statistically high significant influence on all the observed parameters.

Two field studies (I and II) at the University of Nebraska-Lincoln: John Seaton Anderson Turfgrass Research Facility near Mead, NE, USA, were conducted to determine if a new ultra-low volume (ULV) sprayer can apply foliar nutrient, growth regulator, and fungicide treatments, in a manner similar to that of a conventional sprayer. Treatments were applied over creeping bentgrass ‘L-93’ (Agrostis stolonifera L.) managed as a fairway at 561 l · ha−1 and 47 l · ha−1 with the conventional and ULV sprayer, respectfully. Data were collected for chlorophyll content with a chlorophyll meter, and for the normalised difference vegetation index (NDVI) with a turf colour meter. Each plot was harvested for biomass at 21 days after treatment. Study II compared the ULV sprayer and a conventional sprayer, for the control of brown patch (Rhizoctonia solani Kuhn) in creeping bentgrass. The treatments were propiconazole and azoxystrobin. Spray volume was 561 l · ha−1 for the conventional sprayer, and 19 l · ha−1 for the ULV sprayer. Statistical differences in turf quality or dry weight reductions between the conventional and ULV sprayer were not detected. Brown patch control was also similar between the two sprayers, but azoxystrobin provided better control than propiconazole. Even with a 30-fold decrease in application volume, the results indicated that the Kamterter ULV sprayer may be a useful and effective management option for foliar fertiliser and fungicide applications in turfgrass.

The aim of our two-year study (2004-05) was to assess the effects of different foliar fertilizers (calcium chloride, Kalcisal, Kalcisal+Kalcifos and Sanisal) on fruit mineral content. The paper also presents the distribution of some macronutrients (N, K, Mg and Ca) in different parts of ‘Conference’ pears. The treatments consisted of five foliar sprays (at the rate of 0.17% Ca) in two week intervals followed by five (at the rate of 0.35% Ca) in one-week intervals. After 120 days of storage, fruits from the treatments were divided into: peel, calyx end, basal end, and outer part of flesh. Each of them was analyzed to assess the contents of nitrogen, potassium, magnesium and calcium. The mineral content of investigated fruits was strongly affected by fertilizers used as well as by the season. Fruits from non-treated trees contained the lowest amounts of macronutrients (average data of four fruit parts). The higher amounts of potassium, magnesium and calcium was found in 2004. In 2004 the highest concentration of calcium was proved for fruits sprayed with Kalcisal (125.5 mg Ca kg⁻¹ f.w.), and in 2005 for calcium chloride (101.3 mg kg⁻¹ f.w.). The K/Ca ratio varied from 16 to 35 and 21 to 35 for 2004 and 2005, respectively. As far as K/Ca ratio is concerned, no significant differences between pears sprayed with CaCl₂ or Kalcisal in comparison to control was found. On the contrary, in both years of the study, the higher K/Ca ratio for Kalcisal+Kalcifos and Sanisal treatments was noted. Sanisal and Kalcisal+Kalcifos significantly increased N/Ca fruit ratio in 2005, as well as Mg/Ca ratio in all seasons. An analysis of average data for all treatments revealed the highest concentration of investigated macroelements in the peel of fruits. The lowest calcium accumulation was recorded in samples taken near the calyx, and in the outer part of the flesh. The lowest N/Ca, K/Ca and Mg/Ca fruit ratios were investigated for peel, whereas the highest – near the calyx end.

The present investigation was conducted during two successive seasons of 2004/2005 and 2005/2006 in order to study the effect of two different sowing times and two macro- and microfoliar fertilizers on yield and chemical composition of Ruta graveolens plants. Delay in sowing from 20 October to 20 November resulted in significant promotion for herb dry weight (g/m2) as well as percentage and yield of essential oil of herb. In contrast, the accumulation of rutin and coumarin contents was higher at the first sowing time than the second one. The main constituent of essential oil in herb was identified as 2-undecanone. It represented 60.74% of identified herb essential oil at first sowing date and decreased to 55.88% at second date. Both foliar fertilizers, Crestalon and Leaf drip, promoted herb dry weight. Leaf drip was more favorable to improve these criteria than Crestalon. In general, the highest content of essential oil, rutin and coumarin were recorded with application of 1000 or 2000 ppm of Leaf drip. The maximum yield of herb and essential oil resulted in plants of the second date of sowing and fertilized with Leaf drip at 2000 ppm.

Foliar feeding of plants is an important supplementation of soil fertilization in vegetable cultivation. Foliar-fertilized plants deliver high yields of good quality at lower rates of mineral fertilization. In horticultural practice foliar fertilization is also recommended as the most effective method of supplying plants with nutrients under deficiency conditions. An experiment was established to evaluate an effect of foliar application with Florovit and combination Ekolist-Warzywa+Urea on the yield quality of six large-fruit melon cultivars (‘Pacstart’, ‘Yupi’, ‘Gattopardo’, ‘Polydor II’, ‘Seledyn’, ‘Legend’) cultivated in the climatic conditions of central-eastern Poland. The total yield was achieved from Florovit and Ekolist-fertilized plants did not differ significantly. A higher total yield was achieved from Florovit-fertilized plants compared with control object. ‘Yupi’ was characterised by higher total yields compared with the other cultivars. The greatest fruit number per 1 m2 was set by ‘Gattopardo’. On the basis of the results obtained it was found that, due to the highest share of marketable fruit, ‘Yupi’ is the cultivar recommended for cultivation under the growing conditions of central-eastern Poland. ‘Seledyn’ was gave at least unripe fruit whereas ‘Pacstart’ produced the lowest share of disease-affected fruit. An application of the foliar fertilizers reduced the total sugar and monosaccharides content in melon fruit. Regardless of the kind of foliar feeding, most dry matter in the fruit was produced by ‘Pacstart’, total sugar and monosaccharides by ‘Yupi’ and ascorbic acid by ‘Legend’.

A field experiment in growing sweet basil was carried out in the period 2008-2010 in Fajsławice (Lublin region), on podzolic soil. The study evaluated the biometric traits of the plants, yield, the qualitative parameters of herbal raw material and weed infestation of the crop in dependence on growth simulators (Asahi SL, Bio-algeen, Titanit) and the forecrop (winter wheat or spring barley + white mustard cover crop). Plots without foliar application of the growth stimulators were the control treatment. Tillage, mineral NPK fertilization as well as mechanical and chemical weed control were typical for this plant species and consistent with the recommendations for herbal plant protection. A hypothesis was made that the application of growth stimulators would have a positive effect on basil productivity, raw material quality and weed infestation of the basil crop. It was also assumed that the phytosanitary and fertilizing effects of the cover crop would result in higher and qualitatively better yield compared to the cereal forecrop alone (winter wheat). The best quantitative parameters of sweet basil raw material and the highest reduction in air-dry weight of weeds in the crop were observed after the application of the growth stimulators. The forecrop – spring barley + a white mustard cover crop that is ploughed in – also had a beneficial effect on yield and weed infestation of the plant in question. The traditional crop protection method used in the basil crop, without the application of the growth stimulators, resulted in a lower plant height and a smaller number of shoots per plant. This caused higher weed infestation of the crop and a decrease in yield. The positive side of the non-application of growth stimulators was a better chemical composition of basil raw material. Asahi SL and Tytanit yielded the best growth and productivity of the basil plants.
