Item Analiza dynamiki zmian uprawy rodzimych gatunków roślin strączkowych w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Bojarszczuk, Jolanta; Księżak, JerzyItem Analiza dynamiki zmian uprawy rodzimych gatunków roślin strączkowych w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Bojarszczuk, Jolanta; Księżak, JerzyItem Assessment of Physicochemical Properties and Quality of the Breads Made from Organically Grown Wheat and Legumes(MDPI, 2024-04-18) Cacak-Pietrzak, Grażyna ; Sujka, Jerzy; Księżak, Jerzy; Bojarszczuk, Jolanta; Ziarno, Małgorzata; Studnicki, Marcin; Krajewska, Anna; Dziki, DariuszThis study aimed to explore the feasibility of substituting wheat flour with varying levels (10%, 15%, 20%, and 25%) of flour derived from field bean, chickpea, lentil, and pea seeds. The investigation focused on assessing the physical properties of wheat dough and the physicochem ical characteristics of bread samples. The addition of legume seed flours significantly influenced the dough’s development time, particularly with chickpea flour causing a notable increase in this parameter. While dough stability was generally shorter for mixtures containing wheat flour and legume seed flour, chickpea flour was an exception, significantly prolonging dough stability time. Furthermore, the inclusion of legume flours resulted in increased protein, ash, fiber, fat, and phenolic contents in the enriched bread, while the carbohydrate content decreased. Additionally, the crumb exhibited increased redness and yellowness and decreased lightness due to the enrichment of the bread. Notably, the antioxidant activity of bread containing legume flour also increased, with the most significant increase observed when pea flour was utilized. Conversely, negative effects on bread volume, crumb density, and texture parameters were noted with the incorporation of legume addi tives. Taking into consideration the results of both physicochemical analyses and sensory evaluation, it is recommended that the incorporation of the specified legume flours should not exceed 15% in relation to the quantity of wheat flour used.Item Changes in yield and gas exchange parameters in Festulolium and alfalfa grown in pure sowing and in mixture under drought stress(Taylor & Francis, 2018) Staniak, Mariola; Bojarszczuk, Jolanta; Księżak, JerzyCrop performance and yield are the results of genotypic expression as modulated by continuous interaction with the environment. Among environmental factors, water is globally one of the most limiting for crop production. Water resources in the world are steadily diminishing and in many areas, including Poland, more frequent periods of drought are being observed. The aim of the study was to compare the yields and gas exchange parameters of Festulolium hybrid (Festulolium braunii (K. Richt) A. Camus) and alfalfa (Medicago × varia T. Martyn) under different levels of soil moisture (well-watered conditions and drought stress) and cultivation method (pure stand and mixture). The study has shown that all the measured parameters were affected by drought stress. Net photosynthetic rate, transpiration rate, stomatal conductance and dry mass yield were significantly lower under drought stress than under well-watered conditions in all treatment types. Alfalfa grown in a pure sowing showed the strongest reaction to stress, while hybrid Festulolium grown in mixture showed the weakest. It was also found that under stress, grass assimilated CO2 and evaporated water much more intensively in mixture cultivation than in pure sowing. Higher water use efficiency (WUE) was observed in alfalfa and Festulolium growing in mixture only in the first year of the study.Item Characterization of Fungi Communities in Organic Soybean Seeds Using DNA Sequencing: Effects of Cultivar and Location(MDPI, 2026-02) Olszak-Przybyś, Hanna; Przybyś, Marcin; Bojarszczuk, Jolanta; Księżak, JerzyOrganic soybean seeds are susceptible to colonization by numerous fungal pathogens, which can reduce their germination capacity and nutritional quality. This study evaluated fungi transmitted by seeds and their effects on selected seed quality parameters, as well as the influence of variety, location and growing season. In total, 471 fungal isolates belonging to 24 genera and 37 species were obtained from three soybean varieties (Erica, Es Commandor and Cerez PZO) cultivated at two locations during the 2022–2023 seasons. All obtained isolates were identified based on ITS sequencing, and Fusarium isolates were further characterized to the species level using TEF and RPB2 markers. Fusarium spp. was the most frequently isolated genus, accounting for 35.7% of all isolates, followed by Alternaria spp. (15.9%) and Aspergillus spp. (11.9%). Fungal frequency and species diversity differed significantly between years. Seed germination capacity was significantly lower in 2023 than in 2022 and coincided with higher fungal colonization, lower spring temperatures, and increased rainfall. A significant negative Pearson’s correlation (r = −0.58, p < 0.05) was found between fungi abundance and seed oil content, indicating a direct impact of fungal colonization on nutritional quality. These results highlight the role of environmental conditions in seed-borne pathogen communities and the need for monitoring and seed health management to ensure soybean seed quality.Item Comparison of maize yield and soil chemical properties under maize (Zea mays L.) grown in monoculture and crop rotation(Polskie Towarzystwo Magnezologiczne i Uniwersytet Warmińsko-Mazurski w Olsztynie, 2018) Księżak, Jerzy; Bojarszczuk, Jolanta; Staniak, MariolaMaize is one of the crop species that are increasingly grown in no-tillage systems. This approach is conducive better utilization of the agricultural production areas, which - as well as enabling farmers to obtain high yields - improves an overall organization of the agricultural production and its economic efficiency. The aim of this study was to evaluate the yield of maize grown for grain cultivated in monoculture with two methods of soil pre-sowing preparation, and to compare it to the yield achieved in crop rotation. Another aim was to determine the influence of cultivation simplifications on soil chemical properties.The results were derived from field experiments, which were carried out in two sites in Poland. The study showed that the lowest average maize yield was achieved in monoculture with direct sowing. The yields obtained in the monoculture tested in Baborówko were lower by approximately 17% than in the crop rotation system, while in Grabów the respective difference was about 27%. Grain yields in Baborówko were higher by about 33% compared to Grabów. Abandonment of the mechanical cultivation of maize grown in monoculture caused a decrease in the weight of cobs and in the number of grains per cob. The pH of the soil in which maize was grown was more acidic at the end than prior to the experiment, especially in the treatment with crop rotation. The content of P2O5 in the soil was higher after three years of maize cultivation in the direct sowing or full ploughing systems than before the beginning of the experiment, while a decrease in its concentration was recorded in soil cropped with maize grown in crop rotation. The total amount of nitrogen in the soil decreased regardless of the method of pre-sowing soil preparation. The humus content of soil under maize grown in monoculture with direct sowing or with full tillage did not change, while its amount increased in soil under maize grown in crop rotation with cereals.Item Estimation of productivity and nutritive value of pea-barley mixtures in organic farming(WFL Publisher, 2012) Staniak, Mariola; Księżak, Jerzy; Bojarszczuk, JolantaCultivation of legume-cereal mixtures brings natural and economic benefits. Legumes in such cropping develop faster, ripe more uniformly and yield more stably especially in less favourable habitats as compared to legumes in pure stand. Mixed fodder contains more nutrient elements and the quality of dry matter is better than legumes in pure sowing. Such mixtures are also an important element of organic farming. The objective of this research was to evaluate the yielding of Pisum sativum cultivar with different foliage types with Hordeum vulgare cropping depending on the share of components in seeds mass in organic farming. Field experiment was carried out in 2008-2010, split-plot design, in four replications. The first rank factor was the cultivar of P. sativum: Set (bipinnate cultivar) and Terno (semi-leafless cultivar) in 2008 and Set and Ramrod (semi-leafless cultivar) in 2009 and 2010. The second rank factor was the percentage of P. sativum in the mixture: 40, 60 and 80%. In the conditions of reduced precipitation (June 2008) the increase of P. sativum percentage in a mixture caused decrease of the yields, independently of the cultivar, while in the wet year (2009) it caused increase of yields. In 2008 and 2010 the yields of mixture of H. vulgare with evaluated P. sativum cultivars were very similar but in 2009 the yield of mixture with Set cultivar was higher than with Ramrod cultivar. The increasing of percentage of P. sativum seeds in the mass of sown seeds had relatively low influence on its morphological features. Higher settling to the first and the last pod have been observed. The increasing of pod number per plants and number of pods per fruiting node has been noted in the Terno cultivar. The increasing of the P. sativum seeds percentage in the yield of mixture had positive effect on the concentration of total protein and crude fat contents, reducing crude fibre. Better quality of fodder has been obtained from mixture of H. vulgare with P. sativum Set cultivar. A cultivar of P. sativum as well as its percentage in the crop mixture had little influence on the content of phosphorus, calcium and magnesium. The increasing of potassium concentration in fodder with higher share of P. sativum seeds has been observed.Item Evaluation of mixtures of yellow lupine (Lupinus luteus L.) with spring cereals grown for seeds(ALÖKI Kft., 2018) Księżak, Jerzy; Staniak, Mariola; Bojarszczuk, JolantaCultivation of legume-cereals mixtures is considered a good agricultural practice in many European countries, especially in organic and low-input farming systems. The aim of the study was to determine the productivity of mixtures of yellow lupine (Lupinus luteus L.) with spring cereals, depending on the species of grain component and its percentage in mixture. Field experiments were carried out in the years of 2011-2013 at the Agricultural Experimental Station Grabów in Poland, using the system of random sub-blocks, with a control treatment, in four replications. The study included three species of cereals: wheat (Tricicum aestivum L.), barley (Hordeum vulgare L.), and triticale (Triticosecale Wittm. ex A. Camus), as well as three percentages of lupine in the weight of sown seeds: 40, 60, 80%. The experiment was conducted on the soil of good wheat complex, class IIIa. The studies showed that the highest yield was obtained from the mixture of yellow lupine with wheat. Increasing the percentage of lupine seeds resulted in lower mixture yields, regardless of cereal species. Lupine grown in mixtures with cereals formed less pods, seeds per pod and per plant and produced a lower seed weight compared with their counterparts grown in pure stands. Legumes grown in mixture with cereals favorably affected morphological characteristics of cereals, contributing to their higher tillering and producing a higher number of grains per plant. The grain of cereals grown in mixtures with lupine had higher contents of total protein and crude fibre than the grain of cereals grown in pure stands.Item Evaluation of the Concentration of Nutrients in the Seeds of Faba Bean (Vicia faba L. major) and PEA (Pisum sativum L.) Depending on Habitat Conditions(HARD Publishing Company, 2018) Księżak, Jerzy; Bojarszczuk, Jolanta; Staniak, MariolaThe aim of our study was to determine the effect of habitat conditions on the nutrients content in the seeds of different cultivars of faba bean and pea (edible and fodder cultivars). Experiments were located in some different parts of Poland (9 for faba bean, 11 for field pea). Nine cultivars of faba bean, 17 edible cultivars of pea, and 13 fodder cultivars of pea were used in these experiments. The study showed that the contents of components varied between cultivars of both species depending on examined factors. The contents of the components also varied depending on location. In southern Poland the average crude fibre and crude protein contents were higher than in the northern and northwestern parts of the country. Significant differences between cultivars of faba bean were found in the contents of crude fibre, crude protein, and soluble sugars. All the tested faba bean cultivars contained a similar amount of crude fat. The average crude protein and crude fibre content in pea seeds was higher in the fodder cultivars than in the edible ones. The smallest content of fibre among all the cultivars was noted in the northern and the largest in the southeastern regions of Poland. Most cultivars of pea showed a similar sugar content. The most favorable conditions of sugar accumulation occurred in the southern part and the least in the northeastern and the northern parts of the country. Fodder cultivars showed relatively little variability in starch content. The agro-ecological conditions influenced content of concentration of nutrients in the seeds of faba bean and pea.Item Gas exchange parameters in red cover (Trifolium pratense L.) and festulolium (Festulolium braunii (K. Richt) A. Camus) under drought stress(ALÖKI Kft., 2018) Staniak, Mariola; Księżak, Jerzy; Bojarszczuk, Jolanta; Feledyn-Szewczyk, BeataWater deficit in the soil is one of the factors that limit the yield of crops, causing great damage to agricultural production. This is the result of genotypic expression as modulated by interaction with the environment. The effect of water deficit on gas exchange parameters of Festulolium hybrid and red clover grown in pure stand and in mixture were studied. Two-factor pot experiment was performed in the completely randomized block method, with four replications. Objects were evaluated at two soil moisture levels: well-watered conditions and drought stress. The studies have shown that all the measured parameters were affected by drought stress. Net photosynthetic rate, transpiration rate and stomatal conductance were significantly lower under drought stress than under well-watered conditions in all treatments. Red clover grown in a pure stand responded to stress the most, while Festulolium hybrid – the least. It was also found that the highest water use efficiency index (WUE) was observed in Festulolium which proves a more economical water management compared to red clover. The mixtures showed smaller yield losses under drought stress compared to red clover grown in pure stand, which indicates their higher suitability to be grown in areas with less rainfall.Item MAIZE AND SORGHUM YIELDS AS AFFECTED BY NITROGEN FERTILIZATION(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2012) Księżak, Jerzy; Bojarszczuk, Jolanta; Staniak, MariolaItem Nutrient Contents in Yellow Lupine (Lupinus luteus L.) and Blue Lupine (Lupinus angustifolius L.) Cultivars Depending on Habitat Conditions(HARD Publishing Company, 2018) Księżak, Jerzy; Staniak, Mariola; Bojarszczuk, JolantaThe objective of the study was to determine the effects of habitat conditions on the content of nutrient in the seeds of different cultivars of blue and yellow lupine. Experiments were located in different parts of Poland. Sixteen cultivars of blue lupine and eight cultivars of yellow lupine were used in these experiments. The study showed that yellow lupine seeds had a higher protein content then blue lupine, and the contents of this component were varied between both cultivars of this species depending on examined factors, while the fiber content was little varied between species and cultivars. The average fat content in the seeds of blue lupine was slightly higher, the amount of starch was a much higher, and the water-soluble sugars slightly lower than in the seeds of yellow lupine. Significant differences between cultivars of blue lupine were found in the contents of crude fat, water-soluble carbohydrates and alkaloids, and between cultivars of yellow lupine in the amounts of crude fat. The cultivation region did not significantly affect only starch accumulation by the tested lupine cultivars as well as alkaloids in yellow lupine. The contents of the other components were varied depending on the area of cultivation.Item Ocena organizacji gospodarstw specjalizujących się w produkcji mleka w aspekcie dostosowania do zasad dobrej praktyki rolniczej(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Bojarszczuk, Jolanta; Księżak, Jerzy; Staniak, MariolaItem Opłacalność uprawy mieszanek łubinu żółtego ze zbożami(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2014) Bojarszczuk, Jolanta; Księżak, JerzyItem Porównanie opłacalności uprawy grochu i bobiku w zależności od sposobu nawożenia(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2015) Bojarszczuk, Jolanta; Księżak, Jerzy; Staniak, MariolaItem Prolonged drought stress induced changes in yield and physiological processes of Trifolium repens and Festulolium braunii(Academy of Sciences of the Czech Republic, 2020) Staniak, Mariola; Bojarszczuk, Jolanta; Kraska, Piotr; Kwiatkowski, Cezary; Harasim, ElżbietaWater deficit is one of the main environmental factors, and the recognition of plant response to drought stress seems to be crucial for the yield improvement of the important crops. The aim of the study was to investigate the effect of prolonged drought stress on dry matter yield, gas exchange parameters, and relative chlorophyll content in the leaves of Festulolium braunii and Trifolium repens grown in pure stands and in mixture. In the pot experiment, different levels of soil moisture (well-watered conditions and drought stress) and of cultivation method (pure stand and mixture) have been applied. The study has shown that all measured parameters were affected by drought stress. Dry mass yield, net photosynthetic rate (PN), transpiration rate (E), and stomatal conductance were significantly lower under drought stress than under well-watered conditions in all treatment types. T. repens showed the strongest response to stress, whereas F. braunii the weakest when both those species were grown in the pure stand. Under drought conditions, the yield of the mixture was similar to that of F. braunii cultivated in the pure stand, and significantly higher than that of T. repens cultivated in the pure stand. It was also found that under the stress, PN and E of both species in the the mixture was higher than in the pure stand. The highest water use efficiency was observed in F. braunii grown in the mixture. Our research shows, that in regions with limited rainfall, T. repens is more useful for growing in a mixture with F. braunii, than in the pure stand.Item Różnorodność siedlisk segetalnych w łanachroślin uprawnych w wybranych gospodarstwach rolnych województwa dolnośląskiego(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Bojarszczuk, Jolanta; Podleśny, JanuszItem Study on the growing maize (Zea mays L.) in long-term monoculture and rotation(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2018) Księżak, Jerzy; Bojarszczuk, Jolanta; Gałązka, Anna; Niedźwiecki, Jacek; Gawryjołek, Karolina; Lenc, Leszek; Jeske, Małgorzata; Czyż, Ewa; Król, MariaItem Tendencje zmian produkcji i wykorzystania roślin pastewnych w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2016) Księżak, Jerzy; Bojarszczuk, JolantaItem Tendencje zmian produkcji i wykorzystania roślin pastewnych w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2016) Księżak, Jerzy; Bojarszczuk, Jolanta
