    Opis:
    Badania polowe przeprowadzono w latach 2002-2004 w Stacji Badawczej w Mochełku, należącej do Akademii Techniczno-Rolniczej w Bydgoszczy, na glebie lekkiej, kompleksu żytniego dobrego. Łubin wąskolistny uprawiano po pszenicy ozimej. Testowano dwa czynniki: pożniwną uprawę roli: A – podorywka + bronowanie, B – podorywka + bronowanie + międzyplon z gorczycy białej, C – bez uprawy pożniwnej; dawkę herbicydu: a – Afalon 50 WP – 1,25 kg·ha-1, b – Afalon 50 WP – 0,83 kg·ha-1. Stwierdzono, że zaniechanie pożniwnej uprawy roli spowodowało obniżenie plonu nasion łubinu wąskolistnego. Nie udowodniono natomiast korzystnego oddziaływania przyorania międzyplonu ścierniskowego z gorczycy białej na plonowanie łubinu wąskolistnego. Wzrost zachwaszczenia na skutek redukcji dawki herbicydu Afalon 50 WP z 1,25 do 0,83 kg·ha-1 nie wywarł wpływu na plonowanie łubinu wąskolistnego.
    Field experiments were carried out over 2002-2004 at the Mochełek Experiment Station, of the University of Technology and Agriculture in Bydgoszcz, on light good-rye-complex soil. Blue lupin was grown after winter wheat. Two factors were examined: post-harvest tillage: A – skimming + harrowing, B – skimming + harrowing + white mustard intercrop, C – without post-harvest tillage; dose of herbicide: a – Afalon 50 WP – 1.25 kg·ha-1, b – Afalon 50 WP – 0.83 kg·ha-1. It was demonstrated that eliminating post-harvest tillage led to a decrease in the blue lupin seed yield. However the favourable effect of the white mustard stubble intercrop ploughing-in on blue lupin yielding was not significant. The increase in weed infestation as a result of the Afalon 50 WP herbicide dose reduction from 1.25 to 0.83 kg·ha-1 did not affect blue lupin yielding.

    Opis:
    Fruit production should be adapted to future scenarios that are frequently associated with scarce resources, especially freshwater and fertilizers. New biologically-based fruit production strategies, i.e. taking into account tree growth and water status, are required to optimize irrigation and fertilization under abiotic stress conditions. It was hypothesized that a moderate abiotic stress, here deficit irrigation with or without nitrogen deficit, in the preharvest period, could decrease postharvest losses due to diseases and pruning weights due to reduced vegetative growth, without sacrificing the yield and fruit quality. This study was conducted over two years using the same trees of ‘Moncante’ nectarine cultivar grown in a commercial orchard. Trees were assigned to three treatments: (1) full irrigation at 80% estimated crop evapotranspiration (ETc), (2) deficit irrigation, i.e. at 75% of full irrigation, and (3) deficit irrigation and deficit nitrogen, i.e. at 75% of full irrigation and 75% of usual N-fertilization adopted by the grower in this commercial orchard. Deficit irrigation alone and in combination with deficit nitrogen reduced postharvest diseases and pruning weights without significant yield losses. Our results suggest that ETc-based approaches of reduced water irrigation may be a sustainable way to decrease phytosanitary inputs and workload in the orchard while maintaining the orchard performance.

    Background. As a result of the zonal effect of strip tillage with its simultaneous application of fertilizers and the sowing of seeds, and depending on the presence of post-harvest residues, there may be variations in soil properties including that of moisture content. The aim of this study was to assess the spatial diversity of moisture in soil cultivated or prepared for cultivation according to the strip-till one-pass technology, as well as the dynamics of its changes. Material and methods. In field experiments and laboratory tests the diversity of soil moisture was assessed depending on the actual or simulated impact zone of the working parts of hybrid strip tilling and sowing machines and the distribution of post-harvest residues on the soil surface. Results. During the period of intensive growth of plants the water content in the loosened strips of the plant rows was lower than in the uncultivated inter-rows. In these strips there was a rapid infiltration of water after precipitation and a faster decrease in moisture content than there was in the inter-rows. The loosened soil moved away at the time of sowing into the inter-row, or its surface layer, in rainless periods contained less water than the lower layers. Plant mulch on the surface also led to soil having a higher water content. Conclusion. The zonal effect of the working parts of a strip-till and sowing machine causes spatial differentiation of soil moisture. Non-loosened soil zones, especially in rainless periods, contain more water than the cultivated strips in rows of plants. Higher soil moisture is encouraged by covering the soil with a layer of mulch or a layer of loosened soil.
    W wyniku strefowego oddziaływania pasowej uprawy roli z jednoczesną aplikacją nawozów i siewem nasion na glebę i resztki pożniwne może występować zróżnicowanie jej właściwości, w tym wilgotności. Celem badań była ocena przestrzennego zróżnicowania wilgotności gleby uprawianej lub przygotowanej do uprawy według technologii strip-till one-pass, a także dynamiki jej zmian. W badaniach polowych i laboratoryjnych oceniono zróżnicowanie wilgotności gleby w zależności od rzeczywistej lub symulowanej strefy oddziaływania elementów roboczych hybrydowej maszyny do uprawy roli i siewu pasowego oraz rozmieszczenia resztek pożniwnych na powierzchni gleby. W okresie intensywnej wegetacji roślin zawartość wody w spulchnionych pasach i jednocześnie rzędach roślin była mniejsza niż w nieuprawianych międzyrzędziach. W strefie tej występowała szybka infiltracja wody po opadach i szybsze niż w międzyrzędziach zmniejszenie wilgotności po ich ustąpieniu. Gleba spulchniona, odsunięta w momencie siewu w międzyrzędzie lub jej warstwa powierzchniowa, w okresie bezopadowym zawierała mniej wody niż warstwy niżej położone. Większej zawartości wody w glebie sprzyjał również mulcz roślinny na jej powierzchni. Strefowe oddziaływanie elementów roboczych maszyny do pasowej uprawy roli i siewu powoduje przestrzenne zróżnicowanie wilgotności gleby. Strefy gleby niespulchnionej, zwłaszcza w okresach bezopadowych, zawierają więcej wody niż pasy uprawione w rzędach roślin. Większej wilgotności gleby sprzyja jej przykrycie warstwą mulczu lub warstwą gleby spulchnionej.

    Opis:
    Brassica oilseed crops have very high sulfur requirements. The progressive decrease in the sulfur content of soil, the growing share of cruciferous vegetables in agricultural ecosystems and a significant drop in annual wet and dry deposition of sulfur have prompted a growing body of research into sulfur as a valuable fertilizer ingredient. The aim of this study was to determine the effect of sulfur fertilizers applied to soil on nitrogen, phosphorus, potassium, calcium, magnesium and sulfur concentrations in the root residues, straw and oil cake of winter and spring rapeseed. The experimental material was collected from a field experiment conducted in 2005-2008 at the Agricultural Experiment Station in Bałcyny (Poland). The highest concentrations of nitrogen, phosphorus, magnesium and sulfur were noted in the oil cake of both winter and spring rapeseed. Potassium levels were highest in the root residues of winter and spring rapeseed. Winter rapeseed accumulated the highest amounts of calcium in roots, and spring rapeseed – in straw. Sulfur fertilizers applied to soil decreased nitrogen concentrations and increased calcium and sulfur levels in the roots of both spring and winter rapeseed, whereas phosphorus concentrations increased only in the roots of winter rapeseed. Sulfur fertilization led to a drop in the potassium content of winter rapeseed roots (by 0.7 g kg-1 DM) and an increase in potassium levels in spring rapeseed roots (by 1.2 g kg-1 DM). The application of sulfur fertilizers significantly increased potassium and sulfur concentrations in the straw of both spring and winter rapeseed (by 1.3-1.7 and 0.5-0.6 g kg-1 DM, respectively). The application of sulfur fertilizers at optimal doses for winter rapeseed significantly increased the calcium content of straw (by 1.3 g kg-1 DM), but did not lead to differences in nitrogen levels. Sulfur fertilization significantly reduced nitrogen (by 0.7 g kg-1 DM) and calcium (by 0.6 g kg-1 DM) concentrations of spring rapeseed straw. The content of all the analyzed macronutrients increased significantly in spring rapeseed oil cake in response to sulfur fertilization. Sulfur also increased the concentrations of the evaluated macronutrients, excluding nitrogen and phosphorus, in winter rapeseed oil cake.

    Opis:
    The present study was conducted to investigate the effects of different package types and ozone treatments on post-harvest quality of figs. Three different package types (classical-type, modified atmosphere –MAP, consumer-type) and different ozone treatments (0, 5, 10 and 15 minutes) were used in experiments. Purple figs grown in Tekkeköy town of Samsun province were used as the experimental material of the study. Fruits harvested at optimum harvest period were subjected to pre-cooling for a day and then stored in a cold storage at 4°C temperature and 85–90% relative humidity. At the beginning of cold storage and each week of storage, fruits removed from the storage were subjected to weight loss, water soluble dry matter content, titratable acidity, wrinkle, leakage, mold spots, peeling and degustation analyses. Current findings revealed that MAP and 10 or 15-minute ozone treatments had positive impacts on weight loss prevention in figs. While there were not significant differences in other characteristics of treatments, 10 and 15-minute ozone treatments retarded mold spots and leakage in consumer and modified packages.

    Opis:
    Floral exchange markets drive steadily growing interest in ornamental plants sold as cut flowers. Unfortunately, vase life of some of these flowers remains unsatisfactory. Their ornamental value depends on their longevity and number of flowers, as well as overall appearance of the stem during its vase life. Our study determined the effects of storage conditions and Floralife flower food on vase life and ornamental value of Crocosmia ×crocosmiiflora ‘Lucifer’. Crocosmia inflorescences can be attractive cut flowers after meeting some basic requirements. Cutting the branched shoots when the first flower in the main inflorescence was fully open, the second was opening and the subsequent buds showed visible color allowed for maintaining their decorative value for an average of 18.8 days, irrespective of storage conditions and flower food. Vase life and ornamental value depend on storage conditions. Keeping the inflorescences in a semi-lit room (16.8 µmol∙m–2∙s–1), at 18–20°C, and relative humidity of 55–60% or in darkness, at 14–16°C, and relative humidity of 60–70% reduced the number of developed flowers, inflorescence weight and the amount of absorbed solution, and also declined inflorescence vase life. Application of Floralife 200 and Floralife 300 flower food increases the vase life by respectively 7.9 and 8.2 days vs. water, and improves the quality of stored inflorescences.

    Opis:
    Garden perennials are a source of floristry material produced in field or under covers. A perennial producing long, leafy shoots, which in flower arrangements might successfully substitute fern or palm leaves, is Polygonatum multiflorum. The variety characterizing with decorative white margined leaves is ‘Variegatum’. To improve their quality, the growth stimulator Actisil Hydro Plus, which contains 0.6% of active silicon in a form of orthosilicic acid was applied. The aim of the conducted experiment was to estimate the influence of silicon and a place of cultivation (tunnel and open field) on post-harvest quality determined with morphological features, vase life longevity and mechanical properties of Polygonatum multiflorum (L.) All. ‘Variegatum’ stems. The plants were sprayed with water solutions of Actisil in concentrations: 0.2%, 0.3%, and 0.4%, six times during the growing season in weekly intervals, starting from the first decade of May, always in the morning. It was stated that cultivation of Polygonatum in the unheated foil tunnel increases quality of shoots for cut greenery, determined with morphological features and post-harvest longevity. Cultivation of Polygonatum in a foil tunnel and spraying plants with Actisil in concentrations of 0.3 or 0.4% is advantageous due to possibility to increase a number of shoots from 20% to over 31%, their length from 9% to 11% and fresh weight from 52% to 71%, in comparison to control plants. It is advised to treat plants cultivated in a tunnel, with Actisil in concentration of 0.4% as it improved shoots quality evaluated with their diameter and lower leaves blade area. Spraying plants with Actisil in concentrations of 0.2–0.4% in the tunnel and 0.2% in field prolongs post-harvest shoots longevity by 3–4 days. Plants cultivated in the tunnel characterize with higher strength of shoots determined with higher maximum force causing permanent damage and lower stem deflection than plants cultivated in field. Plants grown in a tunnel and sprayed with Actisil in concentrations of 0.4% characterized with the strongest shoots after 14 days of storage, however a similar effect was observed with the concentration of 0.3% and in case of plants cultivated in field and sprayed with 0.4% of Actisil.
