The author has been a regular reader of 'Kwartalnik Historii Nauki i Techniki' ever since its establishment, and presents a number of reflections connected with the Quarterly's anniversary. Above all, he concludes that the Quarterly has always been of much assistance to young people interested in the history of science, in that it has helped them gain valuable knowledge in the field. and has taught them methods of research and interpretation, by providing very good examples of studies by eminent historians of science. It has also always played an important role in integrating the milieu of historians of science and technology in Poland. The author mentions a dozen or so articles published in the Quarterly that have made a lasting impression on him as a reader.

The paper presents results on the effect of agronomic factors on the content of chlorophyll, the biometric parameters of plants and quality of fenugreek seeds. It has been shown that potassium fertilization and inoculation of fenugreek seeds had no significant effect on the plant’s performance. The only trait influenced by those factors was the seed weight per plant; under higher doses of potassium fertilization K2.5 and K3.75, its value was about 10% higher, but fell down by 19.3% in treatments with inoculated seeds compared to non-inoculated ones. Soil water deficit caused reduction of plant height by 15.5%, number of pods by 18.3%, number of seeds per pod by 20%, weight of seeds by 28%, weight of the plant’s aerial parts by 18.0%, and harvest index by 13.2%. In response to water deficit, the content of chlorophyll decreased significantly from 57.8 SPAD units at 43 DAS to 52.4 and 54.0 SPAD units in the next phases (51 and 58 DAS), when 40% and 80% of pods attained the final length. Increasing doses of potassium caused a significant increase in the crude protein (by 3.2-5.4%) and potassium content (by 7-8%) in seeds of fenugreek grown under water deficit. After seed inoculation, an increase in the protein content was found.

The economic analysis is determined by the applied agricultural system, the response of crops to agronomic factors and environmental factors. The aim of this study was to compare the profitability of fenugreek (Trigonella foenum-graecum L.) production under different farming systems in north-eastern Europe. Profitability was determined mainly by the cost of farming operations and treatments. The system with the optimal sowing date (B1 - delayed by 10 days in compare to the earliest) and mechanical weed control (D0) generated the highest profits. The value of fenugreek production was determined at USD 1641.0, and the energy efficiency ratio was estimated at 0.53 to 0.60. The most profitable system was B0 – early sowing date, D1 – chemical weed control, where energy inputs reached 9814.3 MJ·ha⁻¹.

Ekonomiczna analiza zastosowanego systemu rolniczego uwarunkowana jest czynnikami agrotechnicznymi i środowiskowymi. Celem badań było porównanie opłacalności uprawy kozieradki pospolitej w warunkach zróżnicowanej agrotechniki północno-wschodniej Europy. Wykazano, że czynnikami warunkującymi opłacalność produkcji tego gatunku były koszty zabiegów agrotechnicznych. Najkorzystniejszą pod względem opłacalności okazała się technologia z optymalnym terminem siewu (B1 – opóźnionym o 10 dni w porównaniu z kontrolą) i mechaniczną regulacją zachwaszczenia (D0). Wartość produkcji kształtowała się na poziomie 1641,0 USD. Wskaźniki efektywności energetycznej wynosiły od 0,53 do 0,60. Najkorzystniejsza była technologia B0 – wczesny termin siewu, D1 – chemiczna ochrona roślin, a poniesione nakłady energii na tę technologię wynosiły 9814,3 MJ·ha⁻¹.

Dolichols isolated from leaves of the fern Matteucia struthiopteris were present as a mixture of prenologues composed of 14 up to 20 isoprene units with Dol-16 dominating. They comprised approximately 0.004% of the fresh weight of fresh plant tissue and were accompanied by traces of polyprenols (Pren-14 up to Pren-17, Pren-16 dominating). Their structure was confirmed by electropray ionization mass spectrometry (ESI-MS). This is the first time that dolichols have been reported as dominating polyisoprenoid alcohols in plant photosynthetic tissue.
