Wheat is a major crop, an important component of the human diet and important source of animal fodder in the world. Characterization of phenolic profiles of the leading wheat cultivars is important for new opportunities for breeding and eventual commercial production of value-added cultivars rich in beneficial components. A method using ultra-performance liquid chromatography combined with photodiode-array...

The objective of the research was to establish the ranking of the usefulness of winter wheat varieties (Triticum aestivum L.) for cultivation in organic farming, taking into account their competitive ability against weeds, leaf infestation by fungal pathogens and yielding. The study was conducted in the period 2014-2016 in 3 locations in Poland: Experimental Stations of The Institute of Soil Science...

In the years 2014-2016 four commercial winter wheat cultivars, released during 2008-2011, were grown in a field experiment at RZD Osiny according to organic and conventional farming systems. Each year in the first or second decade of May samples of rhizosphere soil were analyzed for numbers of colony forming units (CFU) of phosphate solubilizing microorganisms (PSM) and for acid and alkaline phosphatase...

Celem pracy było porównanie właściwości reologicznych ciasta oraz cech jakościowych pieczywa otrzymanego z mąk pasażowych pochodzących z przemiału ziarna dwóch odmian pszenicy (Tybalt i Wysokolitewka) o zróżnicowanych właściwościach fizykochemicznych. Przemiał ziarna przeprowadzono w 6-pasażowym młynie laboratoryjnym MLU-202 firmy Bühler. Ciasta otrzymane z mąk pasażowych wykazywały duże zróżnicowanie...

Celem badań było porównanie składu chemicznego pszennych mąk pasażowych otrzymanych z przemiału ziarna dwóch odmian pszenicy o zróżnicowanych właściwościach fizykochemicznych. Przemiał ziarna przeprowadzono w 6-pasażowym młynie laboratoryjnym MLU-202 firmy Bühler. Wydajności mąk z poszczególnych pasaży były zróżnicowane, najwięcej mąki uzyskano z pierwszego pasażu wymiałowego, a najmniej z trzeciego...

The experiment was carried out in the years 2014-2016 in two sites: Osiny-south-east Poland and Jadwisin- central Poland. In both places potatoes were grown under two crop production systems: organic and integrated. In Osiny the plantation was placed on heavier soil and in Jadwisn on lighter one. Six potato cultivars from different group of maturity were tested. The biggest impact on the tuber yield...

These studies are based on a field experiment carried out in the years 2011-2016 at RZD IUNG-PIB in Grabów. The experiment consisted of three crop rotations differing with respect to leguminous crops included in these rotation, reflecting three different types of ecological (organic) farms. Crop rotation A, representing a dairy farm, consisted of: maize - cerealpulse mixture (undersown with grass-red...

Toxocara spp. infestations present with a wide spectrum of symptoms, from general inflammation of internal organs with eosinophilic granuloma formulation through ocular or brain involvement. There is also an asymptomatic form. The known factors that influence the clinical form of the disease are the intensity of the infestation, the localization of the larvae, the age of the patient, the efficiency...

Occurrence of culturable Fungi and Oomycota in root-soil habitat of potato cv. Owacja in organic and integrated production systems at Osiny (northern Poland) was compared in 2008–2010. The densities of both pathogens were significantly greater in the organic system. The eudominant fungal taxa (with frequency > 10% in at least one habitat) included species of Fusarium + Gibberella + Haematonectria,...

The aim of this study was to evaluate the yielding of selected quality varieties of winter wheat grown in organic farming in different regions of Poland. The field trials were performed in the years 2014-2015. The analyses included grain yield, its structure, nitrogen nutritional status and presence and intensity of fungal diseases. The results showed that, regardless of locality, Sailor, KWS Ozon...

Labile fractions of soil organic matter (SOM), e.g. hot (or cold)-water extractable C and living (active) microbial biomass (MB) are much more dynamic and sensitive to changes in soil management practices than total SOM and can be useful indicators of soil quality and SOM transformation processes as influenced by different factors, e.g. agro-technical practices (mineral and organic fertilizers). The...

In the years 2014-2015 the study on the suitability of 7 oat varieties: 2 hulled (Bingo, Krezus) and 5 naked (Cacko, Maczo, Nagus, Polar, Siwek) for cultivation in organic farming was done. The experiments were conducted in two locations: Grabów (Mazowieckie province, organic farm of IUNG - PIB) and Chwałowice (Mazowieckie province, organic farm of CDR in Radom). In 2014 the yield of oats was on average...
