    Opis:
    A field experiment was conducted in 2017-2018 in the Agricultural Experiment Station owned by the University of Warmia and Mazury in Olsztyn. The experiment had a randomized block design with three replications. The first experimental factor was a number of common onion cultivars: ‘Whitney Wing F1’, ‘Spirit F1’ and ‘Red Baron’. The second experimental factor was the effect of two plant growth biostimulants; Calleaf Aminovital and Maximus Amino Protect, on the yield and quality of the onions. In the control treatment, plots were sprayed with water. The total yield, marketable yield and the marketable yield as a percentage of the total yield, the weight, vertical diameter and horizontal diameter of each onion bulb, the content of dry matter, total sugars, reducing sugars, L-ascorbic acid and nitrates (V) in the onions were determined in the study. The evaluated cultivars differed significantly with regard to the weight and size of the onions. Onions of cv. ‘Whitney Wing F1’ were characterized by a greater yield, and the weight, vertical diameter and horizontal diameter of the bulbs were all higher than they were for the remaining cultivars. The concentrations of dry matter, total sugars, L-ascorbic acid and nitrates (V) were higher in cv. ‘Red Baron’. The contents of L-ascorbic acid and nitrates (V) were significantly affected by the application of biostimulants, and the effects were more pronounced for onions treated with Maximus Amino Protect. The interaction between the experimental factors had a significant effect on the weight of individual onion bulbs, and on the concentrations of dry matter and L-ascorbic acid in the edible plant parts.

    Opis:
    The aim of this study was to evaluate the yield and mineral composition of storage roots of carrots protected with biological methods, without the use of chemical control agents. The first experimental factor consisted of two carrot cultivars with different maturity periods. The second experimental factor comprised three methods of carrot fly biocontrol, compared in the following treatments: control – unprotected plants, carrots intercropped with dill (cultivar Szmaragd), carrots intercropped with Welsh onions (cv. Parade) and the application of Himal cubes containing paraffin-coated garlic pulp. The storage roots of carrots cv. Nantejska Polana and cv. Flakkese 2 were harvested in the first week of September and in the middle of October, respectively. After harvest, 100 carrot roots were collected from each replication to determine the percentage of roots infested by the carrot fly. In order to evaluate carrot yields in experimental treatments, the total and marketable yield of carrot storage roots were determined. Fifteen storage roots sampled from the marketable yield in each treatment were subjected to chemical analyses. The prepared material was analyzed to determine the content of: total- N, P, K, Mg, Ca and Cu. The organic crop protection methods based on the biological phenomenon of allelopathy as well as the biocontrol agent Himal significantly reduced the carrot fly population relative to the control treatment. An increase was noted in the total and marketable yield of carrots intercropped with Welsh onions, although the species competed for nutrients. Comparable yield was achieved when carrots were protected with Himal. The storage roots of carrots cv. Flakkese 2 intercropped with dill had the highest content of total N, K, Mg and Ca.

    Opis:
    Celem badań była ocena dynamiki wzrostu oraz zawartość suchej masy i wybranych składników organicznych w cebuli zwyczajnej w okresie wzrostu. Doświadczenie polowe przeprowadzono w latach 2012-2013 w województwie kujawsko-pomorskim (53°6′50″N, 19°4′6″E). Materiał badawczy stanowiły rośliny czterech odmian cebuli zwyczajnej: Błońska, Dakota F1, Norvito F1, Octavia. Nasiona wysiewano w II dekadzie kwietnia. Począwszy od 20. czerwca do 5. września wykonywano pomiar cech morfologicznych główek i liści cebuli na 30 losowo wybranych roślinach. Oceniono masę, średnicę poziomą i pionową cebuli, liczbę liści asymilacyjnych oraz zawartość: suchej masy, cukrów ogółem i redukujących oraz kwasu L-askorbinowego. W wyniku przeprowadzonych analiz wykazano, że spośród badanych odmian cebuli, w ocenianym okresie, największą dynamiką wzrostu masy, średnicy poziomej i pionowej główki oraz liczby liści na roślinie charakteryzowała się odmiana Norvito F1. Zawartość suchej masy i cukrów ogółem zwiększała się wraz terminem badań. W ostatnim terminie analiz wykazano, że rośliny odmiany Norvito F1, zawierały najmniej suchej masy, natomiast najwięcej cukrów.
    The aim of this study was to determine the growth rate of onion plants and the content of dry matter and selected organic compounds in common onions during the growing season. Field experiments were conducted in 2012-2013 in the Kujawy-Pomerania Province (53°6′50″N, 19°4′6″E). The experimental materials comprised onion plants of four cultivars: Błońska, Dakota F1, Norvito F1 and Octavia. Seeds were sown in the middle of April. Between 20th June and 5th September 30 onion plants were selected randomly for an analysis of the morphological traits of bulbs and leaves. The following parameters were determined: the weight, horizontal diameter and vertical diameter of bulbs, the number of leaves involved in photosynthesis, and the concentrations of dry matter, total sugars, reducing sugars and L-ascorbic acid. In the group of the common onion cultivars under analysis, onion plants of cv. Norvito F1 were characterised by the highest increase in the weight, horizontal diameter and vertical diameter of bulbs, and the number of leaves per plant in the experimental period. The content of dry matter and total sugars in onions increased throughout the growing season. On the last sampling date, onion plants of cv. Norvito F1 had the lowest dry matter content and contained the highest concentrations of sugars.

    Opis:
    A field experiment was conducted in the years 2017-2018 in the area of the Didactic and Experimental Centre, University of Warmia and Mazury in Olsztyn. The experiment was set up in the randomised split block design, in three replicates. The first experimental factor was four winter cultivars of garlic (Allium sativum L.): ‘Arkus’, ‘Harnaś’, ‘Mega’, ‘Ornak’. Within the scope of the second experimental factor, the effect of amino acid biostimulators Calleaf Aminovital and Maximus Amino Protect on the yield and quality of garlic was analysed. The control treatment comprised plots on which only water was applied. The objective of the study was to estimate selected morphological features of bulbs and the content of nutritional components of garlic cultivated with the use of biopreparations. The morphology and the nutritional composition of the edible part of garlic was estimated. Statistically significant impact of the cultivar on bulb mass and horizontal diameter and on the content of L-ascorbic acid and nitrates (V) in the edible part of garlic was demonstrated. Cultivar ‘Ornak’ was characterised by greater bulb mass (64.62 g), vertical and horizontal diameter (4.09 and 4.14 cm), dry matter content (38.0%) and concentration of reducing sugars (1.18 g 100 g–1 fresh matter). Lower bulb mass, height, content of total and reducing sugars and of nitrates (V) were determined in garlic cv. ‘Arkus’. The cultivation of garlic plants with the use of the biostimulators had a significant effect on the number of cloves in a single bulb. The application of Calleaf Aminovital increased their number to an average of 6 cloves×plant–1. Interaction of garlic plants cv. ‘Arkus’ with Calleaf Aminowital significantly reduced the content of nitrates (V) in garlic relative to the remaining cultivation treatments.
