Opis:
Entomopathogenic fungi are the largest group of microorganisms existing in the soil environment. Occurrence and pathogenicity of entomopathogenic fungi in soil is dependent on many factors affecting the soil environment. The aim of this study was to compare the species composition and the intensity of the occurrence of entomo-pathogenic fungi in soils from monoculture crops of Festuca pratensis Huds. The study material consisted of soil samples taken from the experiment conducted in two experimental stations of the Research Centre for Cultivars Study. The insecticides fungi were isolated from soil using a method of the selective substrate. Three species of entomopathogenic fungi Beauveria bassiana, Isaria fumosorosea and Metarhizium anisopliae were isolated from the study soils using the selective medium.

Opis:
The experience with cultivation of Festulolium braunii (Felopa variety) in mixtures with red clover (Tenia variety), and alfalfa (Tula variety), was founded in April 2007 on an experimental object of Grassland Department and Green Areas Creation UP-H in Siedlce. The first experimental factor were 3-grass-legumes mixtures having the following composition: M1 – Festulolium braunii 50%, Trifolium pretense L. 50%, M2 – Festulolium braunii 50%, Medicago sativa ssp. media 50%, M3 – Festulolium braunii 50%, Trifolium pratense L. 25%, Medicago sativa ssp. media 25%. Combina¬tions with soil’s medium amendment was marked as UG, and without soil’s medium amendment – BUG. In addition, nitrogen fertilization in the annual dose of 60 kg N∙ha-1, potassium 120 kg K2O∙ha-1 and phosphorus in the amount of 80 kg P2O5∙ha-1 were applied on all plots. Detailed study included the chemical composition of plant, which was determined at the Institute of Technology and Life Sciences in Falenty. The obtained results were used to calculate the following measures of the energy of and protein value feed: NEL – net energy of lactation, JPM∙kg-1D.M. – feed unit for milk production, JPŻ∙kg-1 D.M. – feed unit for livestock production, nBO – useful protein, BNŻ – rumen nitrogen balance. Furthermore, using the multivariate comparative of taxonomic analysis method the synthetic comparative measure of forage quality Q was evaluated. The use of soil’s medium amendment, regardless of the types of mixture, cuts and years of research, resulted in higher values of all measures. However, the analysis of synthetic measure of feed quality showed that in terms feed quality the best was the three component Festulolium braunii mixture with Trifolium pratense L. and Medicago sativa ssp. media.

Opis:
The study was conducted in the years 1999–2001 in a meadow with the following fertilizer combinations: control object (without fertilizer), NPK mineral fertilization, fertilizing with manure, manure with NPK fertilization, fertilizing with spent mushroom substrate; spent mushroom substrate with NPK fertilization. The aim of the study was to determine the effect of permanent grassland fertilization both with spent mushroom substrate and the one supplemented with NPK on the up taking of manganese, copper and zinc by the meadow sward. After the cultivation of mushrooms, in comparison to the standard manure, the substrate used in the experiment was characterized by more than twice higher amount of manganese and zinc. However, the amount of copper in the organic materials was similar. In spite of having supplied lager amount of manganese, zinc and similar amount of copper to the mushrooms substrate, it caused the reduction of the uptake of the elements in the meadow sward. In spite of supplying larger amounts of manganese, zinc and copper the reduction of their up taking by meadow sward was observed in comparison to manure mushroom substrate. This may be connected with a slightly alkaline reaction of the soil environment, thus limiting the uptake of the studied micronutrients.

Opis:
Nowadays, substances stimulating the growth and development of different agricultural plant species are used in intensive farming. Some of such plant growth regulators are Asahi SL and Moddus 250-EC. So far the literature dealing with growth regulators has focused mainly on their effects on deciduous trees. Because no data are available on how those substances affect conifer trees, this paper presents description of experiments on the effects of Asahi SL and Moddus 250-EC on the increase of tree height and branch length of Picea pungens and Thuja occidentalis. The research has proved that morphological features of the plants tested in the experiment varied according to which growth regulator was used and in what month the measurements were taken. Conifer trees sprayed with Asahi SL had a bigger yearly height growth rate and bigger growth of branches than those sprayed with the stimulator Moddus 250-EC.

Opis:
Zastosowanie w podłożach superabsorbentów, zwanych także hydrożelami przyczynia się do znacznej oszczędności wody. Jakość muraw trawnikowych zależy w dużym stopniu od częstego podlewania, a co za tym idzie oszczędności pod względem finansowym przy realizacji wydatków związanych z utrzymaniem muraw trawnikowych. Celem pracy jest ocena zadarnienia różnych muraw trawnikowych w zależności od głębokości umieszczenia hydrożelu w podłożu, jak i rodzaju okrywy glebowej. Badania były realizowane w oparciu o dwa doświadczenia polowe założone w trzech powtórzeniach, prowadzone w układzie split- -plot. Jednostką doświadczalną było poletko o powierzchni 1 m2. Pierwsze doświadczenie stanowił trawnik monokulturowy gdzie w siewie czystym badano cztery gatunki traw gazonowych. W drugim doświadczeniu użyto cztery zaprojektowane mieszanki tych samych gatunków traw. W każdej mieszance zastosowano wysiew jednego gatunku trawy jako dominującego (40%) a pozostałe trzy gatunki stanowiły po 20%, i tak: M 1 - życica trwała 40%; M 2 - kostrzewa czerwona 40%; M 3 - wiechlina łąkowa 40%; M 4 - mietlica pospolita 40%.W każdym z doświadczeń zastosowano następujące czynniki badawcze: rodzaj podłoża: a/ bez hydrożelu - " 0" - kontrola; b/ z dodatkiem hydrożelu umieszczonego na głębokości: 5cm; 10 cm; 15cm; okrywa glebowa: a/ gleba uprawna - (P); b/ torf ogrodniczy - (T).Zadarnienie badanych muraw trawnikowych zależało głownie od składu gatunkowego murawy trawnikowej jak i rodzaju podłoża glebowego. Wszystkie badane murawy trawnikowe najlepsze zadarnienie osiągały w wyniku umieszczenia hydrożelu w podłożu na głębokości10 cm. Z kolei rodzaj okrywy glebowej nie miał istotnego wpływu na wartość badanej cechy.
Application of superabsorbents in the subsoil, also called hydrogels contributes to significant water savings. Quality of turf lawns depends largely on the frequent watering, and hence savings in financial terms the implementation of expenditure on maintenance lawn grasses. Evaluation of compactness of different turf lawns depending on the depth of the hydrogel in the subsoil and the type of soil cover was the aim of this study. There were carried out two field experiments, which were established in triplicate, and conducted in a split-plot system. The experimental unit was a plot with an area of 1 m2. The first experiment was a lawn where were studied four species of lawn grasses sown as monocultures. In the second experiment were used four mixtures of the same grass species. In each mixture was applied one grass species as the dominant (40%) and the other three species accounted for 20%. There were: M 1 - 40% Perennial ryegrass, M 2 - 40% Red fescue, M 3 - Kantucky bluegrass 40%; M 4 - 40% Common bent. In each experiment, the following research factors were applied : the type of subsoil: a / without hydrogel - "0" - control, b/ with the addition of hydrogel placed at a depth: 5 cm, 10 cm, 15 cm, Soil cover: a/ cultivation soil - (P) b/ horticultural peat - (T). The compactness of studied turf lawns depended mainly on lawn grass species composition and the kind of subsoil. All tested turf lawns the best compactness achieved by placing the hydrogel in the ground at a depth of 10 cm. The type of soil cover had no significant effect on the value of this feature.

The aim of this paper is to analyze yield variation of Dactylis glomerata and Festuca pratensis varieties grown on organic and mineral soil. This paper has drawn on two field experiments set up and carried out between 2010 and 2013. The experiment was conducted in two experimental stations: one in the Research Centre for Cultivar Testing in Krzyżewo and the other in the Experimental Stations for Variety Testing in Uhinin. The experiment in Krzyżewo was set up on ploughed soil, with spring barley as a forecrop. In Uhnin the experimental plots were located on peat meadow. The experimental plots were sown with varieties of Dactylis glomerata: Niva, Tukan, Amila, Crown Royale and with varieties of Festuca pratensis: Limosa, Pasja, Anturka, Amelka. The full exploitation of Dactylis glomerata varieties was due between 2012 and 2013, whereas for Festuca pratensis it was due between 2011 and 2012. In the experimental plots with the varieties of Dactylis glomerata the grass was harvested six times a year and chemical analysis of the biomass was done taking dry matter only from five cuts. The varieties of Festuca pratensis were harvested four times. Each year in the course of the experiment fresh and dry matter of each cut were weighed. The grass species and their varieties as well as the particular mowing and kind of soil where the grass was grown have an impact on the yield. On mineral soil the yield of Dactylis glomerata was higher than Festuca pratensis. On organic soil the yield of both species was similar. During the two years of experiment the highest yield among Festuca pratensis varieties was noted for Amelka whereas among varieties of Dactylis glomerata the yield was similar and differences were not statistically signifi.

Opis:
Do nawożenia zarówno użytków zielonych jak i muraw trawnikowych można wykorzystać odpady z uprawy pieczarek. Wykorzystanie podłoża popieczarkowego jest dotychczas mało znane. Celem pracy było określenie wpływu podłoża popieczarkowego na masę korzeni muraw trawnikowych o zróżnicowanym udziale życicy trwałej. Doświadczenie polowe założono w roku 2004 na terenie obiektu rolniczego Uniwersytetu Przyrodniczo-Humanistycznego w Siedlcach. W badaniach zastosowano następujące czynniki: 1) rodzaj mieszanki trawnikowej: Wembely (M1); Parkowa (M2); Relax (M3); Półcień (M4), 2) dawka podłoża popieczarkowego (0, 2, 4, 6 kg/m2). Na wszystkich obiektach doświadczalnych stosowno nawożenie mineralne w postaci nawozu Pokon. Pod koniec każdego okresu wegetacji z badanych poletek pobierano próbki darni wraz z systemem korzeniowym na głębokość 10 cm. Na podstawie pobranych próbek darni w każdym roku badań dokonywano oceny suchej masy korzeni w oparciu o metodę badania systemów korzeniowych. Biomasa korzeniowa wytwarzana przez murawy trawnikowe zależała od zastosowanej dawki odpadu popieczarkowego oraz przebiegu warunków pogodowych występujących w latach badań. Spośród badanych mieszanek największą masę korzeniową wytworzyła mieszanka Wembley z 80% udziałem życicy trwałej, a więc mieszanka o największym procentowym udziale tego gatunku trawy, chociaż w obu latach badań bardziej wyrównaną masę korzeniową wytworzyła mieszanka Relax z 40% udziałem życicy trwałej. W miarę zwiększania się dawki odpadu popieczarkowego zwiększała się również ilość wytworzonej masy korzeniowej przez mieszanki trawnikowe. Pozytywne oddziaływanie odpadu popieczarkowego na masę korzeniową wskazuje na potrzebę prowadzenia dalszych badań w tym zakresie. W konsekwencji przyczyni się to do zwiększonej i pożytecznej utylizacji tego odpadu.
To fertilize both grassland and lawns can be used refuses from mushrooms cultivation.Utilization mushroom's refuses is still very little known. The aim of this study was to determine the effect of mushroom's substrate on the root biomasses of turf lawn with varying participation of perennial ryegrass. The field experiment was established in 2004 on agricultural object of University of Natural Sciences and Humanities in Siedlce. It was tested the type of lawn mixtures : Wembely (M1); Parkowa (M2), Relax (M3), Półcień (M4), and the mushroom's substrate in different dose (0, 2, 4, 6 kg/m 2). On the all experimental objects mineral fertilization in the form of Pokon fertilizer was used. The amount of root biomass produced by the tested lawns depended on the mushrooms' refuse dose and the weather conditions occurring during the study years. From tested mixtures the greatest root biomass had Wembley mixture with 80% share of perennial ryegrass so the mixture with the largest percentage of this grass species although in both study years more equal root mass produced Relax mixture with 40% share of perennial ryegrass. With the increase of mushrooms's refuse also increased the amount of root biomass produced by the lawn mixtures. The positive impact of mushrooms's refuse on the root biomass indicates the need for further research in this field. Consequently, this will contribute to increase and useful utilization of this refuse.

In a pot experiment conducted in a greenhouse, the effect of CCC Bercema growth inhibitor to reduce vegetative shoot growth of perennial ryegrass and cocksfoot was studded. The experiment was set up in triplicate. Growth regulator was applied once, in a form of an aqueous solution. The following experimental objects were specified: control object, Bercema with a concentration of 10%, 20% and 30%. Ten measurements were performed every 3 days. The study was conducted under conditions of 12-hour artificial light daily. The results were statistically analyzed using two-factorial variance analysis . It was found that the greatest shoot growth reduction of ryegrass due to the highest inhibitor concentration (B- 30%), but for cocksfoot under the influence of the minimal concentration (B- 10%), compared to the control object. It has been noted that cocksfoot is more sensitive to the applied growth regulator, resulted in significantly greater inhibition of shoot regrowth than for ryegrass. In the experiment with the perennial ryegrass significant differences in the growth of shoots were found under the influence of inhibitor application at a concentration of 30%, compared to the control object. In the case of cocksfoot, all the concentration increases of Bercema inhibitor significantly differentiated the shoots regrowth.

Badania dotyczyły liczebności mikroorganizmów zasiedlających warstwę orną i podorną gleby spod uprawy mieszanek kupkówki pospolitej z koniczyną łąkową, którą zasilano biostymulatorem opartym na fitohormonach (Kelpak SL) i zróżnicowanymi dawkami azotu. Azot zastosowano na czterech poziomach - kontrola (bez azotu), 50, 100 i 150 kg N ha-1, biostymulator na dwóch – kombinacje bez i z preparatem. Materiał glebowy do przeprowadzenia oceny liczebności poszczególnych grup mikroorganizmów pobrano z każdego poletka eksperymentalnego jesienią 2010 roku z poziomu 0-20 cm i 20-40 cm. Analizę prób glebowych na ogólną liczebność mikroorganizmów, na podstawie której wyliczono stosunek ilościowy bakterii i promieniowców do grzybów, przeprowadzono w Zakładzie Mikrobiologii Rolniczej IUNG-PIB w Puławach. Badania wykazały, że zastosowanie biostymulatora w uprawie spowodowało spadek stosunku bakterii i promieniowców do grzybów. Zwiększanie dawki azotu mineralnego również przyczyniło się do zawężenia omawianego wskaźnika. Poziom pobrania materiału glebowego nie wpływał istotnie na stosunki ilościowe drobnoustrojów.

Nitrogen was applied at four levels – control (no nitrogen), 50, 100 and 150 kg N ha-1, biostimulant attwo levels– combinations with and without preparation. Soil material to assess the number of individual groups of microorganisms was collected from each experimental plot in autumn 2010 from the layers 0–20 cm and 20–40 cm. The analysis of soil samples on the overall number of microorganisms on the basis of which was calculated the ratio of bacteria, and actinomycetesto fungi was conducted at the Department of Agricultural Microbiology IUNG-PIB in Pulawy. Studies have shown that the using of biostimulator in the cultivation caused a decrease of the ratio of bacteria and actionmycetes to fungi. Increasing doses of mineral nitrogen also caused to the narrowing of this indicator. The level of soil material collection did not significantly affect the ratios of microorganisms.

Opis:
In the study the physicochemical properties of selected municipal sewage sludge were compared using the reports on waste generation from the years 2007–2012 in the Mazovia voivodship. The selection was done on the basis of different methods of sludge processing and the number of equivalent inhabitants (NEJ) supported by sewage. Physical and chemical properties of municipal sewage sludge were significantly dependent on the method of purification and treatment methods. These sludges were characterized by a high content of organic matter and macronutrients. The amount of heavy metals (Pb, Cd, Cr, Cu, Ni, Hg and Zn) were within acceptable standards for municipal sewage sludge used in agriculture. Municipal sewage sludge treated by biological method with higher nutrients removal did not create bacteriological danger and were used in agriculture, generally to the cultivation of all agricultural products. Sewage sludge sanitized with lime and subjected to anaerobic digestion did not meet bacteriological standards, which eliminated their use in agriculture.

Opis:
Replicated three times, the research was conducted in the experimental field between 2011 and 2014. Three soil conditioners with the following trade names: UGmax, Eko- Użyźniacz, and Humus Active Papka were used in the experiment, separately or together with NPK fertilisers. They were all used on plots sown with two species of grass, Dactylis glomerata of the Bora variety and Lolium perenne of the Info variety. The plant material from both grass species was tested for the concentration of ADL fraction (% DM), cellulose (% DM), and hemicellulose (% DM). It was found that the concentration of cellulose, hemicelluloses, and the ADL fraction was significantly higher in the biomass of Dactylis glomerata than in the biomass of Lolium perenne. The grass from the plot with the UGmax soil conditioner applied had the highest amount of cellulose and hemicellulose. The lowest amount of those organic compounds was found in the grass treated with UGmax together with mineral fertilisers and in plants treated with Humus Active, together with mineral fertilisers. However, the fertilisers and conditioners did not increase the ADL content in both grass species.
