A field experiment was conducted in the years 2002- 2004 at the Zawady Agricultural Experimental Station (52o06’ N; 22o06’ E), belonging to the University of Podlasie in Siedlce, Poland. The investigated factors were two soil tillage systems (traditional and reduced) and seven methods of weed control in potato canopies with herbicide application. The aim of the study was to determine the influence of tillage systems and weed control methods on the weed species composition and weed density. Tillage systems, weed control methods and atmospheric conditions prevailing in the study years significantly varied weed infestation of potato canopies at the beginning of vegetation and before tuber harvest. The lowest number of weeds, compared to the control treatment, was recorded in the treatments in which chemical and mechanical weed control had been applied. The treatments with the traditional tillage system also showed lower weed infestation than those in which simplifications had been applied.

A three-year field experiment was conducted in 2002-04 to evaluate the effects of soil tillage and weed control methods (including herbicides and their mixtures) on the content of polyphenols in edible potato tubers, cv. Wiking. The results obtained indicated that the content of polyphenols in non-peeled and peeled tubers depend on the methods of soil tillage and weeding, as well as on the years of cultivation. The content of polyphenols in the tubers subjected to the initial treatment (peeling) decreased to 7.2-14.9%, compared to the level of polyphenols before peeling.

The experiment was conducted in the years 2004-2006 in a private farm in the village of Frankamionka in Zamość district. There were two experimental factors: I. Cultivation methods – sole cropping and strip intercropping; and II. Tending methods – mechanical, mechanical-chemical, and chemical weed control. The subject of the study was weed infestation of the Mela variety of common bean. Beans were sown between 30 April and 5 May. Weed infestation was assessed in the last week before harvesting by determining its floristic composition and the frequency of occurrence of particular weed species, as well as the air-dry weight of weeds. The dominant weed species were Galinsoga parviflora, Echinochloa crus-galli, Chenopodium album, and Amaranthus retroflexus, which comprised 84.7% of the total number of weeds. Strip intercropping markedly reduced the number of weeds per unit area (by 50%), as well as the dry weight of their aerial parts. The most effective method of weed control was the mechanical-chemical method, which resulted in the lowest occurrence of weeds. It also significantly reduced the weight of weeds.

A special role in improving soil fertility is ascribed to green manures. Organic manuring can also influence on the quantity and quality of vegetable yield. The secondary effect of winter catch crops (VV – hairy vetch, TR – white clover, SC – rye, LM – Italian ryegrass, BRT – turnip rape) and weed control methods on the yielding, biometric parameters of ears and selected components of nutritive value in sweet corn were examined. The effects of an application of green manures were compared to the effect of farmyard manure (FYM ) – 30 t·ha-1 – and control treatment without organic manure (NOM). Two methods of weed control were used: hand weeding and a mixture of herbicides Mustang 306 SE (florasulam + 2.4 D) + Titus 25 WG (rimsulfuron). Cultivation of sweet corn after FYM and VV most beneficially affected the crop’s yield performance, ear weight, kernel weight per ear and sugars content. Ears were the longest when harvested in FYM and VV plots and NOM whereas ear fulfillment was the best in FYM and TR plots. Ear diameter was the greatest for sweet corn cultivated after FYM, LM and BRT. The highest dry matter content was determined in kernels of corn following LM and protein content after LM, VV and TR. Ascorbic acid content increased after all the catch crops compared with FYM and NOM. When weeds had been chemically controlled, corn produced larger ears which, however, had less kernel rows compared with hand weeded plants.

Three-year-long field and storage experiments were carried out to evaluate changes in concentrations of some organic acids in ‘Rywal’ and ‘Saturna’ potato tubers as affected by herbicides used during the growing period. The tubers were stored for 3 and 6 months at 4℃ and 8℃ at relative humidity of 95%. The weed control method did not change acid concentrations in the tubers. However, significant differences between the cultivars were seen. ‘Saturna’ had a higher content of citric, tartaric and fumaric acids, while that of malic acid was lower than in the ‘Rywal’ cultivar. There was a negative correlation between organic acids under study and malic acid after the harvest. The storage period and a lower storage temperature promoted accumulation of malic acid in both cultivars. A reverse relationship was noted in the case of other acids under study. The highest decrease, up to 70%, was found for fumaric acid assessed after 6 months of storage of the ‘Saturna’ cultivar.

A three-year field experiment was conducted in the years 2002-2004 at the Experimental Farm at Zawady owned by the University of Podlasie to evaluate an effect of soil tillage and weed control methods including herbicides and their mixtures on weed infestation and yielding of edible potato cv. Wiking. It was found that soil tillage methods significantly differentiated the potato tuber total yield, weed number determined at the onset and the end of vegetation and weed air dry matter before closing of potato rows. Compared with the control treatment where weeds were mechanically controlled, increased weed control intensity (including herbicides) significantly reduced weed infestation, which was followed by significantly increased tuber total yield by 2.17 to 5.56 t ha-1 and the share of commercial fraction of tubers yield in the total yield excluding variant 5 in which a single herbicide, (that is Barox 460 SL) was applied.

A field experiment was conducted in the years 2008- 2010 at the Research Station of the Faculty of Agricultural Sciences, University of Life Sciences in Lublin, on brown soil with a slightly acidic pH, a high content of available phosphorus and potassium as well as an average magnesium content. The experiment was set up in a random split-plot design with four replications, with two methods for controlling weed infestation: I. mechanical – weeding of inter-rows twice; II. chemical – the herbicide Afalon Dyspersyjny 450 SC (a.i. linuron, 900 g×ha-1). Next, potassium, calcium and magnesium contents were determined in maize and in the dominant weed species. Based on the dry weight yield of maize and the biomass of particular weed species, nutrient uptake per hectare area was calculated. The chemical method of weed control reduced both the number and dry weight of weeds more than the mechanical method. The dominant species in the maize crop were Echinochloa crus-galli (L.) P. Beauv., Chenopodium album L., Galinsoga parviflora Cav., and Cirsium arvense L. All the weed species examined were more competitive than maize in accumulating potassium, calcium and magnesium. Galinsoga parviflora Cav. was the most competitive species with maize for potassium, Cirsium arvense L. for calcium, and Chenopodium album L. and Polygonum lapathifolium L. subsp. lapathifolium for magnesium. Weeds are serious competitors in taking up nutrients relative to crop plants; their share in the total uptake of macroelements from the soil by the maize crop and weeds together was considerable and it averaged as follows: for K – 35%, Ca – 27.3%, Mg –27.4%.

A field experiment was conducted in 2010-2012 on a private farm located in the village of Frankamionka in the administrative district (powiat) of Zamość, on brown soil with slightly acidic pH, and the average abundance of zinc and iron. The experiment was set up in a random split-plot design with four replications, with seven methods for controlling weed infestation: 1) no weeding control, 2) hand weeding control, 3) linuron (Afalon dyspersyjny 450 SC), 4) linuron + metribuzin (Afalon dyspersyjny 450 SC + Mistral 70 WG), 5) linuron + chlomazone (Harrier 295 ZC), 6) linuron + chlomazone + metribuzin (Harrier 295 ZC + Mistral 70 WG), 7) bentazon (Basagran 480 SL twice). The objective of the study was to determine the effect of weeding control methods on the content of iron and zinc in the seeds of cv. Jaś Karłowy common bean (Phaseolus vulgaris L.). The highest seed yield, on average 29.39 dt ha-1, was obtained on the plots where weeds were controlled by the application of the herbicides Harrier 295 ZC + Mistral 20 WG just after sowing. The lowest seed yield was harvested on unweeded plots – 6.77 dt ha-1 on average. Statistical analysis showed a significant effect of the weed control methods and the weather conditions in growing seasons on the content of iron and zinc in bean seeds. The lowest amount of zinc, an average of 36.11 mg kg-1, was found in beans from unweeded plots. The use of the herbicides Afalon dyspersyjny 450 SC + Mistral 70 WG, Harrier 295 ZC and Harrier 295 ZC + Mistral 70 WG significantly increased the zinc content compared to the un weeded control and manual weeding. The highest iron concentration, on average 75.12 mg kg-1, was observed in seeds from unweeded plots. Significantly less iron accumulated in beans from plots weeded manually and by application of the herbicides Harrier 295 ZC and Harrier 295 ZC + Mistral 70 WG.

A field experiment involving the cultivation of common valerian was conducted on loess soil in Abramów (Lublin region) in the period 2007-2009. Qualitative parameters of herbal raw material obtained from this plant as well as in-crop weed infestation were evaluated depending on the protection method and forecrop. Hand-weeded plots, in which a hand hoe was used, were the control. In the other treatments, weeds were controlled using various herbicides and a mechanical implement (brush weeder). Potato and winter wheat + field pea cover crop were the forecrops for common valerian crops. A hypothesis was made that the use of a brush weeder and herbicides not registered for application in valerian crops would have a positive effect on this plant’s productivity and weed infestation in its crops. It was also assumed that the introduction of a cover crop would allow the elimination of differences in the forecrop value of the crop stands in question. The best quantitative and qualitative parameters of common valerian raw material as well as the largest reduction of incrop weed infestation were recorded after the application of the herbicides which were not type approved. The use of the brush weeder in the interrows also had a beneficial effect on productivity of the plant in question, but secondary weed infestation at the end of the growing season of common valerian turned out to be its disadvantage. Traditional crop protection methods used in common valerian crops were less effective in weed infestation reduction and they resulted in lower plant productivity and raw material quality. Potato proved to be a better forecrop for common valerian than winter wheat + field pea; however, this positive effect was not confirmed statistically. The following annual weeds: Chenopodium album, Galinsoga parviflora, Stellaria media, were predominant in the common valerian crop. Traditional weed control methods resulted in the dominance of some dicotyledonous weeds, such as Viola arvensis, Galium aparine, Capsella bursa-pastoris.

Wyniki badań pochodzą z doświadczenia polowego przeprowadzonego w latach 2008-2010 w Rolniczej Stacji Doświadczalnej Zawady należącej do Uniwersytetu Przyrodniczo- Humanistycznego w Siedlcach. Dwuczynnikowy eksperyment założono metodą split-plot, w trzech powtórzeniach, na glebie zaliczanej do kompleksu żytniego bardzo dobrego i klasy bonitacyjnej IVa. W doświadczeniu badano dwa czynniki. Czynnikiem I były odmiany ziemniaka: Satina, Tajfun, Cekin, czynnikiem II – sposoby pielęgnacji (odchwaszczania) z udziałem herbicydów i ich mieszanin: Command 480 EC, Command 480 EC i Afalon Dyspersyjny 450 SC, Stomp 400 SC, Stomp 400 SC i Afalon Dyspersyjny 450 SC oraz obiekt kontrolny – pielęgnacja mechaniczna. Wykazano, że stosowanie zabiegów mechaniczno-chemicznych z udziałem herbicydów i ich mieszanin przyczyniło się do ograniczenia zachwaszczenia w uprawie ziemniaka. Obliczenia statystyczne wykazały istotny wpływ właściwości odmianowych, sposobów odchwaszczania oraz warunków pogodowych na liczebność chwastów, plonowanie ziemniaka oraz wysokość roślin i uszkodzenia poherbicydowe. Dla praktyki rolniczej zaleca się odchwaszczanie mechaniczno-chemiczne z dwukrotnym użyciem herbicydów (przed wschodami i po nich) oraz mechaniczno-chemiczne z zastosowaniem mieszanki herbicydów przed wschodami ziemniaka.
