Opis:
In vitro fertilization involves many issues that need to be regulated by law. The main one is the status of the embryo and arising from it other concerns such as cryoconservation of embryos, assisted reproductive techniques, gamete donation, surrogacy, or preimplantation diagnosis. This paper surveys the legal regulation of in vitro fertilization at different levels of the law systems, from international standards, through regional regulations, to the national law.

Opis:
The purpose of this study has been to determine the effect of fertilisation with urea-ammonium nitrate (UAN) solution enriched with P, Mg or S on the content of macronutrients in the grain and straw of maize. The following fertilisers were tested in the field experiment: ammonium nitrate, urea, UAN - 32% N; RSM+S - 26% N + 3% S; RSM+P(Medium) - 26% N and 4.80% P; RSM+P(Starter) - 21% N and 7.86% P; UAN + Mg - 20% N + 4% Mg. In each year of the experiment, significant differentiation in the contents of P, K, Ca, Mg and S in maize grain and straw was observed, depending on the applied nitrogen fertilisation. However, considering the average values from each treatment achieved over the three years, it was demonstrated that the fertilisation significantly changed only the content of P and S in grain and K and Ca in straw of maize. The removal of nutrients was the highest in the second year of the research and amounted in kg∙ha-1 : P - about 100, K - about 350, Ca - about 80, Mg - about 35 and S - about 31, which in turn were differentiated over the years of the experiment in the three years. The removal of P, K, Mg and S also significantly depended on fertilisation. Significant differences, however, most often concerned the control treatment relative to the fertilised ones. The contribution of grain to the accumulation of nutrients also varied significantly in the three years of the experiment. Significantly the lowest share of grain in terms of P and S accumulation was noted in maize grown without N fertilisation.

Opis:
This study compared the species composition and rate of entomopathogenic fungi occurrence in cultivable soil following the application of a mineral-and-organic fertiliser produced from brown coal. The material for testing consisted of soil samples collected in the second year of the experiment on two dates in 2015 (spring and autumn). The experiment was carried out on the following plots: control plot (no fertilisation); a plot fertilised with mineral fertilisers NPK presowing + N60 for top dressing; a plot fertilised with NPK presowing + manure; a plot fertilised with a fertiliser produced from brown coal at a dose of 1 t/ha NPK presowing + N20 for top dressing; and a plot fertilised with a fertiliser produced from brown coal at a dose of 5 t/ha NPK presowing + N40 for top dressing. Entomopathogenic fungi were isolated from soil of particular fertilisation experiment plots using insect traps (Galleria mellonella larvae) as well as a selective medium. Three species of entomopathogenic fungi, i.e. Beauveria bassiana, Metarhizium anisopliae s.l. and Isaria fumosorosea, were isolated using two methods, from the soil samples collected from particular fertilisation experiment plots on two dates, i.e. spring and autumn. Fungus M. anisopliae s.l. proved to be the predominant species in the tested soil samples. The addition of the mineral-and-organic fertiliser, produced based on brown coal, to the soil at both applied doses contributed to an increase in the number of infectious units (CFUs) of entomopathogenic fungi formed in relation to the control plot.

Opis:
The quality of plants can be assessed according to the basic quantitative nutrient ratios. Moreover, proportions and relationships between macronutrients in plant biomass can be an indicator of the composition of plants and nutrient limitation. The research deals with the influence of soil amendment with mineral, organic and mineral-organic fertilisation on quantitative changes in nutrient ratios determined for camelina, white mustard and spring barley cultivated on light soils in subsequent years. A 3-year pot experiment was conducted with two doses equivalent to 70 kg N ha-1 (I) and to 170 kg N ha-1 (II). Plant material was subjected to chemical analyses in order to assess the macronutrient content, after which mutual proportions of individual nutrients were calculated based on the acquired data. Changes in ratio values were visualised using statistical tools, i.e. multivariate analysis of variance MANOVA and standard analysis of variance ANOVA. Regardless of the applied fertilisation, white mustard showed the highest values of most calculated nutrient ratios, although the values of nutrient ratios were consistent with those given in the literature as adequate only for spring barley. Generally, the fertilisers applied in a dose equivalent to 170 kg N ha-1 resulted in higher values of nutrient ratios, which was observed especially in the case of NPK. The study clearly demonstrated that the plant species diversity as well as fertilisation play a crucial role in quantitative changes of nutrient ratios. It is worth stressing that both organic fertiliser and mineral-organic fertiliser similarly affected nutrient ratio values.

Opis:
Sorghum is a cereal crop of major importance in global production. It is grown in hot and dry regions of the world. In Poland, this species has so far not been cultivated for grain due to unfavourable climatic conditions. Currently, climate warming and the extension of the growing season provide an opportunity to introduce sorghum into grain cultivation. Three grain sorghum cultivars Albanus, Anggy, GK Emese were used in the ongoing microplot trials and three different nitrogen rates were applied: 80, 100 and 120 kg ha-1. The research was conducted over two growing seasons. The aim of the study was to determine the effect of cultivar and level of nitrogen fertilisation on the yield, yield structure and grain protein content of sorghum. A differentiated response of cultivars to nitrogen fertilisation was shown. Albanus and Anggy cultivars have similar yield potential and reaction to nitrogen fertilisation, and the optimum nitrogen dose for the cultivars is 100 kg of nitrogen per hectare, and an increased dose does not significantly increase the yield. Regardless of the level of nitrogen fertilization, the GK Emese variety always showed a higher protein yield compared to the other tested sorghum varieties. The cultivar GK Emese showed the highest yield potential. In 2020 it exhibited the highest increase in grain and protein yield along to increase of nitrogen fertilisation.

Opis:
Badania prowadzono w gospodarstwie Zakładu Doświadczalnego Melioracji i Użytków Zielonych w Falentach, zajmującym 180 ha użytków rolnych (grunty orne - 85 ha, łąki - 72,5 ha, pastwiska - 22,5 ha). W okresie badań uprawiano tam głównie rośliny z przeznaczeniem na pasze treściwe i objętościowe dla inwentarza żywego, z rosnącym udziałem kukurydzy w strukturze zasiewów. Celem pracy było wykazanie korzyści środowiskowych i ekonomicznych wynikających ze zmiany struktury zasiewów i planów nawożenia opracowanych na podstawie bilansu fosforu w gospodarstwie. W bilansach po stronie przychodów uwzględniono ilości fosforu wnoszonego do gospodarstwa z zakupionymi nawozami mineralnymi, paszami, ziemiopłodami, zwierzętami hodowlanymi oraz opadami atmosferycznymi. W rozchodach uwzględniono ilości fosforu wyniesionego z gospodarstwa w sprzedanych produktach zwierzęcych (żywiec, mleko, obornik, gnojówka) oraz roślinnych (ziarno, słoma, siano). Zmieniająca się struktura zasiewów w okresie 1998-2002 oraz zwiększone zużycie obornika w nawożeniu gruntów ornych i łąk umożliwiły wykorzystanie niemalże całych zasobów tego nawozu w gospodarstwie, tym samym ograniczając nawożenie mineralne fosforem. Zmiany w produkcji roślinnej i technologii żywienia bydła przyniosły nie tylko wymierny zysk środowiskowy, lecz również zmniejszyły koszty nawożenia fosforem przy jednoczesnym wzroście produkcji w gospodarstwie.
The study was carried out in the Experimental Farm of Reclamation and Grassland Farming in Falenty that occupied 180 ha of croplands (arable lands - 85 ha, meadows - 72.5 ha and pastures 22.5 ha). Plants intended for concentrated and bulk fodder for livestock with the increasing share of maize were the main crops in the study period. The aim of the work was to demonstrate natural and economic advantages arising from changes in the cropping system and to elaborate fertilisation plans based on phosphorus balance in the farm. Phosphorus introduced to the farm with purchased mineral fertilisers, fodder, crops, breeding animals and atmospheric precipitation was taken as an input in the balance. Output consisted of the phosphorus removed from the farm in sold animal (slaughter cattle, milk, manure, slurry) and plant (crops, straw, hay) products. In the years 1998-2002 the changes of cropping system and increased application of manure to arable lands and grasslands enabled to utilise almost all resources in the farm and thus to limit mineral fertilisation with phosphorus. The changes in plant production and technology of cattle nutrition brought about measurable environmental profits but also decreased the costs of phosphorus fertilisation with simultaneous increase of production in the farm.

Opis:
The study reported here was to determine the effect of an application of organic and mineral materials and their mixtures, combined with mineral fertiliser regime, on the content of selected macroelements in cocksfoot grass and maize. The trial was a completely randomised arrangement with three replicates. Two experimental factors were tested: factor A – fertilisation with organic and mineral materials ( sewage sludge fresh and composted, hard coal incineration ashes , calcium carbonate, mixture of this components) and factor B – mineral fertilisation. The observed effects are indicative of the legitimacy of applying sewage sludge and its mixture with hard coal ash to fertilise agricultural crops as this would reduce reliance on mineral fertiliser, which is very desirable in sustainable agriculture. Mineral fertilisation applied to both the test plants significantly reduced their contents of calcium and magnesium but it increased their content of potassium.

Opis:
Agricultural biogas plants are not only a place for processing waste resulting from animal husbandry, but also for generating electricity and heat as well as organic fertiliser. In a four-year experiment, pellets were used as organic fertiliser in the establishment of an experiment with fast-growing oxytrees. The study aimed to investigate the growth and stem thickness increment, overwintering in the first and subsequent years of cultivation under the conditions of north-eastern Poland. The dried digestate and the pellets made from it were characterised by a high content of macroelements (N – 1,95%, P2O5 – 1,1%, K2O – 1,3%). The applied pellet from an agricultural biogas plant under oxytree seedlings due to its slow decomposition had a good effect on the growth of oxytrees in the second and third years. The average growth of oxytrees in the second year was 209.7 cm, and in the third year, 246.8 cm. The growth of oxytrees fertilised with pellets made from the digestate of an agricultural biogas plant was 13% higher than that of trees growing on the control strip.

Opis:
The aim of the research was to evaluate the effect and interaction of sprinkler irrigation and nitrogen fertilisation on the grain yield and baking value of ‘Monsun’ spring wheat cultivar grown in light compacted soil. A field experiment was performed in 2013-2014 in an experimental field of the Department of Land Improvement and Agrometeorology, the UTP University of Science and Technology, at Mochełek, in the vicinity of Bydgoszcz. It was found that sprinkler irrigation significantly increased the spring wheat grain yield. The grain from sprinkler-irrigated stands demonstrated greater plumpness; it contained significantly less protein and gluten and showed a lower sedimentation value, as compared with the grain of non-sprinkler-irrigated plants. However, the protein yield produced under sprinkler irrigation conditions was on average 11% higher, compared to the control conditions. The effect of nitrogen fertilisation on the spring wheat grain yield and quality corre¬spond to earlier findings. Similarly to other research reports, a regular yield increase and enhanced quality of baking features along with an increase in the nitrogen rate were identified. Considering the quantitative and baking features of the grain yield, it was found that the optima nitrogen fertilisation rate in ‘Monsun’ spring wheat, in both water variants, was 180 kg.ha-1 (pre-sowing 120 kg .ha-1 and top dressing 60 kg ha-1).
