Field experiments were carried out in 2015–2017 on medium heavy mixed rendzina. The aim of the study was to assess the yield and weed infestation of winter spelt wheat cultivars (Oberkulmer Rotkorn, Badengold and Frankenkorn) under foliar application with Santaura Pro+ or Pro Horti Micro Amin Mg fertilizers. Among the evaluated spelt cultivars, the largest yield of grain, as well as the largest number and weight of grains from ear was produced by Badengold cv., while the highest 1000-grains mass was characterized by Oberkulmer Rotkorn cv. Prohorti Micro Amin Mg foliar fertilizer was more yield-forming. Compared to the control object, three-fold application of this preparation resulted in a significant increase in the grain yield, the weight of 1000 grains, as well as number and weight of grains in the ear. Santaura Pro+ fertilizer also had a positive effect on the yielding of spelt, however differences in relation to the control object were statistically insignificant. Tested foliar fertilizers did not differentiate the weight of weed in the canopy of spelt.

W doświadczeniu polowym, przeprowadzonym w latach 2003–2007 w Mochełku koło Bydgoszczy, na glebie kompleksu żytniego dobrego, oceniano wpływ nawożenia (147 kg NPK·ha-1, 221 NPK·ha-1), ochrony roślin (bez ochrony roślin, herbicyd, herbicyd + fungicyd) i gęstości siewu (400 ziaren·m-2, 600 ziaren·m-2) na zachwaszczenie pszenicy ozimej odmiany Tonacja uprawianej w krótkotrwałej monokulturze. W badaniach wykazano znaczny wzrost liczby i masy chwastów w pszenicy uprawianej po sobie bez stosowania herbicydów. Zastosowanie herbicydu Huzar 05 WG (jodosulfuron metylosodowy + mefenpyr dietylu) ograniczało zachwaszczenie.

W latach 2004–2005 w Rolniczym Zakładzie Doświadczalnym w Bałcynach, należącym do Uniwersytetu Warmińsko-Mazurskiego, prowadzono badania nad określeniem skutków przestawiania uprawy żyta ozimego z systemu konwencjonalnego na ekologiczny. W pierwszym przypadku uprawiano je zgodnie z zasadami rolnictwa konwencjonalnego, stosując nawozy mineralne i pestycydy. W drugim zaś realizowano dwuletni okres przestawiania uprawy roślin na system ekologiczny. W obu systemach uprawy żyto wysiewano w stanowisku po pszenicy ozimej. W systemie konwencjonalnym uzyskano średnio 5,47 t·ha-1 ziarna żyta ozimego. Przestawianie jego uprawy na system ekologiczny obniżyło wydajność o 27,8%. Zawartość białka i P w ziarnie żyta z obiektu z uprawą przestawianą na ekologiczną była mniejsza, natomiast K, Mg i Ca – większa niż żyta z obiektu konwencjonalego.

Praca jest analizą wykorzystania ziemi do produkcji użytecznego białka zwierzęcego niezbędnego do zaspokojenia egzystencjalnej potrzeby żywieniowej ludzi. Za wskaźnik opisujący to wykorzystanie ziemi przyjęto ilość białka użytecznego zawartego w mięsie i mleku wyprodukowanych na hektarze ziemi przeznaczonej pod produkcję pasz dla bydła mlecznego w gospodarstwie specjalistycznym w roku. Drugim wskaźnikiem obrazującym podjęty problem badawczy była ilość osób, których roczne zapotrzebowanie na minimum niezbędnej wielkości białka zwierzęcego można pokryć z jego produkcji na ww. hektarze powierzchni paszowej bydła. Poziomy pierwszego wskaźnika analizowane były w zależności od wielkości pięciu wybranych czynników. Czynnikami, które najsilniej oddziaływały na poziomy rozpatrywanych wskaźników wykorzystania ziemi, były: jakość gleb i wydajność mleczna krów. Poziomy drugiego wskaźnika określono na podstawie wielkości pierwszego wskaźnika oraz przyjętych trzech możliwych udziałów (25%, 50% i 75%) białka zwierzęcego w ogólnym rocznym zapotrzebowaniu na białko osoby o masie 70 kg. Liczba osób, dla których można by wyprodukować roczną, niezbędną wielkość użytecznego białka w mleku i mięsie bydła z ha powierzchni paszowej, wahała się od 6,9 do 37,3.

The experiment concerning the effect of furnace waste on the chemical composition of maize was conducted under conditions of a three-year pot experiment. The arable soil was amended with bottom ash in the amount of 23.33 g ∙ pot-1 as well as with increasing doses of cadmium (between 3 and 15 mg ∙ kg-1 soil d.m.). Introduction of ash and cadmium in the amount from 3 to 5 mg ∙ kg-1 d.m. to the soil had a significant effect on the increase of the yield of above-ground parts and roots of maize. The application of cadmium in doses from 7 to 15 mg ∙ kg-1 caused a considerable reduction in the yield of the tested plant. It was shown that the applied furnace ash influenced the decrease in the yielding of maize. Introduction of furnace ash to cadmium contaminated soil significantly influenced the increase in the content of Na, K, Mg, Ca and Si in maize biomass and the decrease in the content of P in maize. Among the studied elements, K was translocated from the roots to the above-ground parts most efficiently, and Na and Si – least efficiently, the evidence of which are the values of the translocation factor for these elements. The research shows that ash in cadmium contaminated soil influenced immobilization of phosphorus, and thereby limited the phytoavailability of this element. It was established that the above-ground parts took up more K, Mg, Ca, P, Si with the yield while and maize roots took up more Na. The lowest uptake of the studied metals by maize was observed in the treatment where only furnace ash was applied.

The study objective was to assess the allelopathic impact of the cut aboveground vegetative shoots of the selected lawn cultivars of L. perenne on the decorative value and species composition of the sward, including the share of dicotyledons. The studies were conducted in field conditions. The following indicators of the allelopathic impact of L. perenne were chosen: the share of the sown cultivars and dicotyledons in the lawn sward, general aspect, sward density and overwinter survival in object A, where the cut biomass was left, and in control object B, from which the biomass was removed immediately after cutting. The biomass of ‘Nira’ and ‘Stadion’ cultivars, cut and left on the lawn surface, exhibited auto-allelopathic properties by reducing their own share in the sward. The share of dicotyledons in the sward was reduced to the largest extent in the treatment where the cut biomass of ‘Nira’ cultivar was left. Only the ‘Stadion’ cultivar had a significantly lower sward density and a poorer general aspect of the sward in objects where the cut biomass was left in comparison with the objects where the cut biomass was removed. All the cultivars under study had better overwinter survival results in the objects where the cut biomass was left on the lawn surface.

The paper analyses the presence of invasive alien species and rare taxons among crop weeds in the Ułęż commune. The study is based on phytosociological relevés taken according to the Braun-Blanquet method. In total, 99 phytosociological relevés were taken. The research was conducted in 2016 and 2017. Ten rare regional and cross-regional species were found among weeds in cultivated crops. These were: Agrostemma githago, Arnoseris minima, Avena strigosa, Chenopodium polyspermum, Consolida regalis, Veronica opaca, Veronica polita, Veronica agrestis, Bromus secalinus, and Centaurea cyanus. Some of the most common species in that area included Centaurea cyanus and Bromus secalinus, while Avena strigosa also belonged to frequent components of the local flora. Other species were recorded rarely or very rarely. Additionally, in the crops, there was a group of 16 invasive alien species. Setaria pumila had the largest vegetal cover and the largest number of positions. There were some more frequently recorded species like Echinochloa crus-galli, Galinsoga parviflora and Conyza canadensis, with Avena fatua being quite common as well. Other species quite often found were: Amaranthus retroflexus, Galinsoga ciliata, Veronica persica and Oxalis fontana. However, species such as Setaria viridis, Solidago canadensis, Bidens frondosa, Epilobium ciliatum, Alopecurus myosuroides, Bromus sterilis and Parthenocissus inserta were rarely or very rarely found in the crops.
