Przeprowadzono badania właściwości fizyko-chemicznych i bakteriologicznych wody ze studni przydomowych położonych w okolicach Zakładów Azotowych „Puławy " i Uzdrowiska Nałęczów w latach 1996-2000. Studnie w okolicach ZA „Puławy" wykazały znacznie wyższy poziom azotanów, bakterii typu kałowego oraz ogólnej ich liczby.

The objective of the examinations was sanitary hygienic assessment of well water within the Nitrogen Plant „Puławy" area reach compared to the wells located some distance off the plant and within the Nałęczów resort. The samples were collected for five years (1996-2000) and examined for the following physicochemical determinations: colour, turbidity, flavour, pH, total hardness, basicity, chlorides, iron, manganese, nitrites, nitrates, ammonia, oxidizability and bacteriological determinations: bacterium coli and coli faeces as well as total count of microorganisms. The examinations showed considerable bacteriological contamination and that with nitrate nitrogen, iron, manganese and high turbidity of the well water examined. The wells in the N. P. " Puławy" demonstrated a substantially higher level of nitrates, faecal bacteria and their total count. Well water is polluted due to uncontrolled activity of the N. P. "Puławy", domestic sewage and industrial wastes, improper location of wells and in some cases, their wrong protection.
Gatunek Nicotiana rustica (2n=4x=48) należący do rodziny Solanaceae jest naturalnym amfidiploidem gatunków N. paniculata (2n=24) i N. undulata (2n=24). Pochodzi z Ameryki Południowej, skąd jego uprawa rozprzestrzeniła się na inne kontynenty. Kolekcja N. rustica zgromadzona w Instytucie Uprawy Nawożenia i Gleboznawstwa - Państwowym Instytucie Badawczym w Puławach składa się obecnie z 83 obiektów, które zostały zebrane dzięki wymianie prób nasion z polskimi i zagranicznymi ośrodkami hodowlanymi. Opracowywanie charakterystyki użytkowej poszczególnych obiektów polega na gromadzeniu danych morfologicznych, fenologicznych oraz odpornościowych. W pracy oceniono 83 obiekty kolekcyjne pod względem 13 cech morfologicznych jakościowych oraz 5 cech ilościowych. Wykorzystano wyniki obserwacji i pomiarów przeprowadzonych w warunkach polowych w latach 1980, 1986 oraz 1992. W obrębie kolekcji N. rustica stwierdzono niewielkie zróżnicowanie międzyodmianowe, o czym świadczą podobieństwa dotyczące wielu cech budowy morfologicznej oraz niskie wartości współczynników zmienności analizowanych cech ilościowych. Największy współczynnik zmienności (CV) wyliczono dla wysokości roślin (16,65%), a najmniejszy dla liczby dni do początku kwitnienia (12,00%).

The species Nicotiana rustica (2n=4x=48), a member of the Solanaceae family is a natural amphidiploid whose progenitors are the diploid species of N. paniculata (2n=24) and N. undulata (2n=24). It is native to South America, from where it spreaded across the world. The collection of N. nistica maintained at the Institute of Soil Science and Plant Cultivation - State Research Institute in Puławy currently comprised 83 accessions, which were collected by acquisitions from foreign countries and from Polish breeding centres. The aim of the evaluation was to determine morphological, phenological and disease-resistance traits. The study assessed the variability of 13 qualitative and 5 quantitative traits in 83 N. rustica accessions. Observations and measurements which were conducted in the field experiment in the years 1980, 1986 and 1992 were used. The similarity of many morphological characters and low values of variability coefficient for the examined quantitative characters indicate that small differences existed among the tested varieties of N. rustica. The highest value of variability coefficient was found for the plant height (16.65%), and the smallest for the number of days until the beginning of inflorescence (12.00%).
The subject of the work is to discuss the regional aspects in the work of the Institute of Soil Science and Plant Cultivation - State Research Institute in Puławy (henceforth referred to as ISSPC-SRI). All spheres of the Institute’s activity have been taken into account during the analysis. The basic sources of information were research plans, reports and publications whose authors were ISSPC-SRI employees. According to the analysis, regional aspects are reflected in ISSPC-SRI research conducted as part of statutory activities, long-term program and various types of projects. Regional aspects are conspicuous both in the diagnosis of the current condition and in forecasting changes in agriculture. They enrich, broaden and objectify assessments. They are also the premises for improving systems of agricultural advisory and strategic planning.

Celem pracy jest omówienie aspektów regionalnych w działalności Instytutu Uprawy Nawożenia i Gleboznawstwa – Państwowego Instytutu Badawczego w Puławach. Analizę przeprowadzono uwzględniając wszystkie sfery działalności Instytutu. Podstawowe źródła informacji stanowiły plany badań, sprawozdania oraz publikacje, których autorami byli pracownicy IUNG-PIB. Stwierdzono, że aspekty regionalne znajdują odzwierciedlenie w badaniach IUNG-PIB prowadzonych w ramach działalności statutowej, programu wieloletniego oraz różnego rodzaju projektów. Aspekty regionalne uwidaczniają się zarówno w diagnozach stanu aktualnego jak i przy prognozowaniu zmian w rolnictwie. Wzbogacają one, poszerzają oraz obiektywizują oceny. Są też przesłankami doskonalenia systemów doradztwa rolniczego i planowania strategicznego.
An Internet model for the assessment of grain loss risk caused by Phaeosphaeria nodorum (syn. Septoria nodorum) is presented in the paper. The model is divided into two functional layers: user interface and calculation layer. Eight factors having a significant impact on the disease development were taken into account: pathogen incidence, stand density, precipitation, the degree of infestation of three top leaves, use of growth regulators, fungicide application dose, controlledtraffic cropping and susceptibility of cultivars. The principle of operation of the model and the method of operating it are presented.
The session was organized by the Institute of Agrophysics of the Polish Academy of Sciences and the Department of Soil Science of the University of Maria Curie-Sklodowska in Lublin. Lublin Scientific Society was the host of the session. Many professor Dobrzanski`s pupils and co-workers from among Lublin and other Polish scientific institutions took part in the Session; his former students, many invited guests and members of the closest family.An exhibition was also organized, which displayed the most important papers, books and other scientific achievements of Professor Dobrzanski.The aim of the session was to present the contribution of Professor Dobrzański to soil science, with special attention to soil physics as well as to the development and strengthening of many Lublin scientific institutions where soil science constitutes the basic scientific activity. Besides His scientific achievements, also his remarkable work as administrator and organiser of two universities in Lublin, i.e. University of Maria Curie-Sktodowska and the Academy of Agriculture, where Professor Dobrzański held the position of the Rector, was commemorated. Also His great efforts to develop the activity of the Polish Academy of Sciences, as its Vice-President and Chairman of the Agricultural and Forestry Section has been underlined. Four papers were devoted to all above mentioned field of activities of Professor Dobrzański. They were presented by his students, today professors in various universities: R. Turski - University of Agriculture in Lublin, S. Uziak - University of Maria Curie-Skłodowska, S. Zawadzki - President of the Agricultural and Forestry Section of the Polish Academy of Sciences, and J.Gliński - Director of the Institute of Agrophysics of the Polish Academy of Sciences. In the discussion many other professors (S. Nawrocki, C. Tarkowski, R. Dębicki, R. Walczak, J. Gawlik, and A.Kusiński) very emotionally stressed the gread and outstanding role of Professor Dobrzański in their life and scientific activity. The final part of the session was continued at the Institute of Agrophysics in Lublin-Felin, which is bearing the name after Professor Dobrzański. Key words: Professor Dobrzański, role in soil science, agrophysics, development of Lublin scientific centre.
