Opis:
In 2003–2005, a two-factors field experiment was set up on sandy soil of low useful water retention. The aim of the study has been to determine the effect of irrigation and mineral fertilization on the quality of some species of stone fruit trees. The treatments were designed by the split-plot method in 7 replications with cherry, 5 replications with peach, and 4 replications with plum trees. Swards between the trees and herbicide fallows in the rows of trees were maintained. Two factors were considered: subcrown irrigation and mineral fertilization. The mineral fertilization comprised the following variants: 0 NPK –no fertilization, 1 NPK – 130 kg NPK ha–1, 2 NPK – 260 kg NPK ha–1 for cherry and plum trees, and 0 NPK –no fertilization, 1 NPK – 150 kg NPK ha–1, 2 NPK – 300 kg NPK ha–1 for peach. Irrigation and fertilization differentiated concentrations of macro- and micronutrients in fruits of cherry, peach and plum trees. Irrigation resulted in a higher content of sugars and vitamin C in the dry matter of peaches and a lower concentration of sugars in cherries. A higher dose of mineral fertilizers depressed the dry matter content in fruit of plum trees and the concentration of sugars in the fresh matter of cherries.
Doświadczenia polowe przeprowadzono na glebie lekkiej o małej retencji wody użytecznej. Badano wpływ nawadniania i nawożenia NPK na jakość owoców wiśni, brzoskwini i śliwy. Wszystkie doświadczenia założono metodą losowanych podbloków w układzie zależnym (ang. split-plot), w 7 powtórzeniach w doświadczeniu z wiśnią Łutówka, 5 – z brzoskwinią Redhaven i 4 – w doświadczeniu ze śliwą Cacanska Rana. Czynnikiem badanym było nawadnianie podkoronowe oraz nawożenie mineralne. W uprawie wiśni i śliwy zastosowano następujące dawki: 0 NPK – bez nawożenia, 1 NPK – 130 kg NPK ha–1 (40+30+60), 2 NPK – 260 kg NPK ha–1 (80+60+120). W uprawie brzoskwini: 0 NPK – bez nawożenia, 1 NPK – 150 kg NPK ha–1 (40+30+60), 2 NPK – 300 kg NPK ha–1 (80+60+120). Nawadnianie i nawożenie mineralne różnicowało zawartość makro- i mikroskładników oraz azotanów w owocach wiśni, brzoskwini i śliwy. Zastosowane nawadnianie wpłynęło istotnie na zawartość cukrów i witaminy C w suchej masie brzoskwini oraz koncentrację cukrów w owocach wiśni. Wysoka dawka nawozów przyczyniła się do zmniejszenia się istotnie zawartości suchej masy w owocach śliwy oraz koncentracji cukrów ogółem w świeżej masie owoców wiśni.

Opis:
The research was conducted in 2011-2012, at the Experimental Station in Lipnik near Stargard Szczeciński, on soil classified as Haplic Cambisol, with low useful water retention. The experiment was designed with a split-plot method and repeated seven times. Grass cover was maintained in the row middles while the area underneath the trees was kept as herbicide fallow. The trees were planted in 4x2 m spacing. The assessment concerned the influence of irrigation and NK fertilisation on the dry matter and chemical composition of cherry fruit from the cultivars Kelleris 16 and Łutówka. Micro-irrigation was used at water potential in soil lower than 0.01 MPa. According to agronomic recommendations, nitrogen fertilizers were applied in early spring and potassium fertilizers in autumn in the following doses: 0 NK (control, no fertilization), 1 NK – 80 kg.ha-1 (40+40), 2 NK - 160 kg.ha-1(80+80), according to agronomic recommendations. Ammonium nitrate containing 34% of nitrogen and potash salt containing 60% of potassium were used for fertilization. Observations of the irrigated trees showed an increase in the dry mass in their fruit, as well as a decrease in nitrogen, potassium and magnesium concentrations, but an increase in the amount of calcium. Chemical analyses of the fruit harvested from the trees fertilized with nitrogen and potassium demonstrated an increase in the analysed traits (macro- and micronutrients), at both 1NK and 2NK fertilization levels.

Opis:
Dry matter, crude protein, crude fat, crude ash, crude fibre and elements (phosphorus, potassium, sodium, calcium, magnesium, zinc, iron, manganese, lead, chromium, molybdenum, cadmium, cobalt, nickel and copper) were determined in extracted and unextracted Moringa oleifera leaves. The leaves were ground in a laboratory grinder (unextracted leaves) and a portion was subjected to continuous comprehensive water extraction at 95-100°C (extracted leaves). Next, densification was carried out in a rotary evaporator, where the material was dried natively in vacuum. The chemical content of the samples was analysed according to standard methods. The concentration of P was determined by the colorimetric method. An Atomic Absorption Spectrometer was used to determine K, Na and Ca by emission flame spectroscopy, and Mg, Zn, Fe, Mn, Pb, Cr, Mo, Cd, Co, Ni and Cu by absorption flame spectroscopy. The nutritional value of herbs depends on the chemical composition of dry mass, especially the content of crude protein, mineral components and fibre fractions. The crude protein content of the extracted and unextracted leaves was 13.6 and 31.6% dry matter (d. m.), respectively. No crude fibre was found in the moringa leaf extract. Dried leaves contained 8% d. m. of crude fibre. Concentrations of crude fat in unextracted leaves implicated that they had five-fold more lipids than extracted from leaves. Total carbohydrates appeared to be the main component of dry mass. More total carbohydrates were found in the extract than in dried leaves (71 and 50% d. m., respectively). The research showed significant differences in the content of macronutrients between extracted and unextracted leaves of moringa. The extracted leaves contained higher quantities of all the studied macroelements. Moringa oleifera leaves may be considered to be a good and safe source of Fe, Zn and Cu. No Ni or Cd was found in the leaves of moringa.

Opis:
The study included an assessment of the chemical composition of three varieties of sea buckthorn (Ascola, Habego and Leikora) cultivated with and without an application of mycorrhizal fungi. Micorrhization was conducted with ectomicorrhizal mycelium, which is symbiotic for plants of the olive family. The study was conducted in 2014, at the Experimental Station in Lipnik (53°20′35″N 14°58′10″E), Poland. The soil in which the plants were grown belongs to rusty soils and is classified as Haplic Cambisol. The experiment was conducted in a randomized block design with five replications (one shrub - one replicate). The content of nutrients and selected macroelements was determined in leaves of the plants. The mean crude protein content in the leaves reached 20.3% of dry mass. Mycorrhization decreased the protein concentration in the leaves of the tested varieties except the variety Leikora, which responded with a protein content increase. The crude fat content in the leaves of mycorrhized plants was higher by 4.7% than in the samples without mycorrhization. Application of mycorrhizae decreased the crude fibre content in the examined varieties. The least crude fibre was found in leaves of cv. Ascola (9.6%). Sea buckthorn leaves are a rich source of macroelements (N, P, K, Mg and Ca). The results of the study on mycorrhization of sea buckthorn do not demonstrate unambiguously the direction of changes in the content of basic nutrients and macroelements.
