W pracy przedstawiono plonowanie czterech odmian jęczmienia jarego (Ars, Diva, Havila, Bielik) w płodozmianie i ośmioletniej monokulturze na glebie lessowej środkowej Lubelszczyzny, Dowiedziono, że monokultura zmniejszała plon ziarna jęczmienia jarego średnio o 16.9% w porównaniu z płodozmianem. Spośród badanych odmian jęczmienia jarego najbardziej przydatnymi do uprawy w monokulturze były odmiany Diva i Ars.

W latach 1990-1994 przeprowadzono doświadczenia polowe, na glebie kompleksu żytniego dobrego, w których porównywano produktywność zmianowań zbożowych z udziałem 25 i 100% pszenżyta ozimego i uprawę międzyplonów ścierniskowych. Najwyższy plon jednostek zbożowych, białka ogólnego i wartość energetyczną w przeliczeniu na jeden hektar uzyskano w zmianowaniu D (jęczmień jary - peluszka - owies - pszenżyto), a najmniejszą z C (jęczmień jary - owies - peluszka - pszenżyto). Efektywność (przyoranych) międzyplonów była wyższa tylko w zmianowaniu odmian pszenżyta ozimego (S) i w zmianowaniu C. W przypadku uprawy pszenżyta w monokulturze bardziej wskazane jest zmianowanie odmian niż uprawa tylko jednej odmiany (Malno).

Doświadczenie polowe prowadzono w latach 2001-2006 w GD Czesławice (środkowa Lubelszczyzna) na glebie płowej wytworzonej z lessu (II klasa bonitacyjna). W badaniach uwzględniono nagoziarnistą formę jęczmienia jarego uprawianego w płodozmianie i 6-letniej monokulturze. W obu systemach następstwa roślin zastosowano ekstensywną i intensywną pielęgnację zasiewów. Czynnikiem regenerującym stanowisko w monokulturze była dodatkowo uprawa międzyplonów ścierniskowych (gorczyca biała, wyka jara + peluszka) oraz wsiewki poplonowej (życica westerwoldzka), których biomasę po uprzednim skoszeniu przyorywano na jesieni. Analizowano wpływ poszczególnych sposobów regeneracji stanowiska w monokulturze na efektywność energetyczną uprawy jęczmienia jarego, konfrontując wyniki z monokulturą bez międzyplonu oraz z płodozmianem. Udowodniono, że intensywna pielęgnacja oraz wysiew międzyplonów w monokulturze jęczmienia jarego miały pozytywne oddziaływanie na plonowanie zboża, ale powodowały pogorszenie wskaźnika efektywności energetycznej. Wynikało to z większej pracochłonności i nakładów siły pociągowej stosowanych w takich technologiach. Najlepsze efekty energetyczne gwarantowała uprawa jęczmienia w płodozmianie pielęgnowanym ekstensywnie.

A field experiment was conducted in the period 2006- 2008 in the Uhrusk Experimental Farm belonging to the University of Life Sciences in Lublin. The experimental factor was the type of stubble crop ploughed in each year after harvest of spring barley: white mustard, lacy phacelia, winter rape, and a mixture of narrow-leaf lupin with field pea. In the experiment, successive spring barley crops were grown one after the other (in continuous monoculture). The aim of the experiment was to evaluate the effect of stubble crops used on the size and structure of barley yield. The three-year study showed an increasing trend in grain yield of spring barley grown after the mixture of legumes, lacy phacelia, and white mustard compared to its size in the treatment with no cover crop. Straw yield was significantly higher when barley was grown after the mixture of narrowleaf lupin with field pea than in the other treatments of the experiment. The type of ploughed-in stubble crop did not modify significantly plant height, ear length, and grain weight per ear. Growing the mixture of leguminous plants as a cover crop resulted in a significant increase in the density of ears per unit area in barley by an average of 14.7% relative to the treatment with winter rape. The experiment also showed the beneficial effect of the winter rape cover crop on 1000-grain weight of spring barley compared to that obtained in the treatments with white mustard and the mixture of legumes. All the cover crops caused an increase in the number of grains per ear of barley relative to that found in the control treatment. However, this increase was statistically proven only for the barley crops grown after lacy phacelia and the mixture of legumes.

The study was carried out in 2003–2005 in the Bezek Experimental Farm (University of Life Sciences in Lublin). The experimental fi eld was situated on light loamy sand soil. The phosphorus content in soil was high, in potassium medium, in magnesium low. The humus content was 1.2%. The experiment was carried out in randomized blocks in three replications. The aim of the investigation was to compare three doses of herbicides in winter triticale canopy (Janko cv., Woltario cv., Krakowiak cv.) cultivated in monoculture. The herbicides Atlantis 04 WG and Factor 365 EC were applied at full recommended doses (200 gha-1), at doses reduced to 75% and 50%. The control was not treated with the herbicides. The weed infestation level was determined by means of the quantitative-weighting method at two dates: the fi rst one at the 6th week after herbicide application and the second one before harvest. The density of weed individuals was counted; the species composition and air– dry biomass of above-ground parts were estimated from the randomly selected areas of 1 m x 0.25 m at four sites of each plot. The density of weeds and weed air dry weight were statistically analysed by means of variance analysis, and the mean values were estimated with Tukey’s confi dence intervals (p=0.05). It was found that the number of weeds and air dry mass of weeds in the control were signifi cantly higher in comparison with the herbicide treated objects. The application of different doses of herbicides did not differentiate signifi cantly the weed infestation level in the winter triticale canopy. Viola arvensis, Matricaria maritima, Chenopodium album and Apera spicaventi were dominant species of weeds in the winter triticale canopy. The selection of cultivars did not influence the canopy weed infestation level.

The research on impact of Cleonus piger Scop. (Coleoptera; Curculionidae) feeding and the occurrence of other pest insects on milk thistle plants grown in monoculture and crop rotation after cereals, with two different seeding dates was carried out in the years 2003–2005. The infestation and density of C. piger larvae in roots of plants grown in monoculture increased with subsequent developmental phases and subsequent years of the experiment. Feeding resulted in the decrease in crop yield by 40% compared to the crop rotation treatment. In crop rotation stands, the infestation of milk thistle roots by C. piger larvae was 4–5 times lower at the final phase than in monoculture. Postponing seeding by three weeks led to the decrease of infestation and density of C. piger larvae, but the crop yield was lower than that from the earlyseeded stands. No other phytophagous species of economic importance were found.

The present study was conducted in the years 2007- 2008, after 6-year-long experiments in the cultivation of spring barley in a crop rotation system and in monoculture. The other experimental factor was the spring barley protection method. Intensive protection involved comprehensive treatment of barley (in-crop harrowing, seed dressing, application of herbicides, fungicides, a retardant and an insecticide). Extensive protection consisted only in in-crop harrowing, without the application of crop protection agents, except for seed dressing. The above mentioned factors formed the background for the study on the cultivation of white mustard and oats, as phytosanitary species, in successive years. In the test plants, no mineral fertilization and crop protection were applied. Such agricultural method enabled an objective assessment of the consequent effect of monoculture, crop rotation and crop treatments. A hypothesis was made that the cultivation of the phytosanitary plants in the stand after 6-year-long barley monoculture would allow obtaining the level of yields and weed infestation similar to those of the crop rotation treatments. It was also assumed that the cultivation of white mustard and oats would eliminate differences in plant productivity caused by the negative influence of extensive protection. It was proved that the cultivation of the phytosanitary plants eliminated the negative influence of monoculture on the level of their yields and weed infestation. However, the test plants did not compensate negative consequences of extensive protection. In spite of this, white mustard and oats effectively competed with weeds, and the number and weight of weeds in a crop canopy did not cause a dramatic decline in yields. In the test plant canopy, the following short-lived weeds were predominant: Chenopodium album, Galinsoga parviflora, Echinochloa crus-galli. The absence of herbicide application resulted in the compensation of perennial species: Elymus repens and Cirsium arvense.
