Opis:
Adhesion in repair systems is one of the most important factors affecting their durability. Elaboration of a reliable nondestructive test method to perform an adhesion mapping is one of the most important tasks. A majority of NDT methods applicable for the assessment of concrete structures are based on the propagation of various types of stress waves. In this paper, the influence of the repair material type (polymer-cement or polymer) and quality of the concrete substrate (roughness, microcracking, not cleaned surface) upon propagation of stress waves in a repair system was studied in view of developing a reliable NDT procedure for the field assessment of bond quality in concrete repairs.

Opis:
Greenhouse cultivation of four cultivars of cherry tomato (Goldita, Faworita, Flavorino, Organza) on the substrates used for the second time (cocofibre and rockwool) did not show any differences in their yielding. Fruits obtained from cultivation on the cocofibre contained less dry matter and vitamin C. During the vegetation period some changes in fruit quality were observed. In the first weeks of fruiting more organic acids and less of vitamin C were observed in fruits. At the time of full fruiting (II period) the content of vitamin C was at its highest and at the same time the content of organic acids and dry matter at the lowest. At the end of vegetation (III period) fruits contained more dry matter and total sugars). Cultivars significantly differed in respect to yielding and fruit quality. The highest content of the investigated components was characteristic for Favorita and Goldita cultivars and the lowest for Organza. However, that cultivar produced the highest total and marketable yield.
Uprawa szklarniowa czterech odmian pomidora drobnoowocowego (Goldita, Faworita, Flavorino, Organza) na podłożach użytkowanych powtórnie (włókno kokosowe i wełna mineralna) nie wykazała istotnych różnic w ich plonowaniu. Owoce pochodzące z uprawy roślin na podłożu kokosowym zawierały mniej suchej masy oraz witaminy C. W okresie wegetacji obserwowano zmiany w jakości owoców. W pierwszych tygodniach plonowania w owocach notowano więcej kwasów organicznych natomiast najmniej w nich witaminy C. W pełni owocowania (II termin) zawartość witaminy C była w nich największa, a jednocześnie najmniejsza zawartość kwasów organicznych oraz suchej masy. Pod koniec wegetacji (III termin) owoce posiadały więcej suchej masy i cukrów ogółem. Odmiany istotnie różniły się pod względem zarówno plonowania, jak i jakości owoców. Największą zawartością badanych składników odznaczały się owoce odmian Favorita i Goldita, najmniejszą zaś owoce odmiany Organza. Ta odmiana natomiast wydała największy plon ogólny i handlowy.

Opis:
Yield and fruit quality of cucumber depend on such factors as plant cultivar, plant nutrition and the cultivation method. The presented paper contains results confirming the usefulness of rockwool and coconut fibre as well as the application of the fertigation system in cucumber growing. Studies on the growing of cucumber Onyks F1 cultivar were carried out in the years 2003–2005 in an unheated greenhouse. A two-factorial experiment was established. One experimental factor consisted in the fertigation control methods including Soltimer device and the starting tray. The other factor included substrate types: rockwool Agroban and coconut fibre Ceres. Plant distribution was 2 plants per one square metre. On the basis of the presented studies, it was found that greenhouse cucumber yielding was influenced by the frequency of nutrient supply, by climatic conditions in the given year and by the applied substrate type. The applied media of rockwool Agroban and coconut fibre Ceres did not exert any influence on plant yielding. On the other hand, a significant effect on the total and the marketable fruit yield was exerted by the cooperation between the fertigation control method and the substrate type.
O plonie ogórka i jakości jego owoców decydują takie czynniki, jak: odmiana, podłoże, odżywianie roślin i pielęgnacja. W pracy tej sprawdzano przydatność wełny mineralnej i włókna kokosowego przy zastosowaniu fertygacji. Badania nad ogórkiem przeprowadzono w latach 2003–2005 w szklarni nieogrzewanej. Do badań użyto odmianę Onyks F1. Założono doświadczenie dwuczynnikowe. Jednym czynnikiem były rodzaje sterowania fertygacją: Soltimer i taca startowa, a drugim podłoża: wełna mineralna Agroban i włókno kokosowe Ceres. Zagęszczenie wynosiło 2 rośliny na 1 m2. Na podstawie przeprowadzonych badań stwierdzono wpływ częstotliwości podawania pożywki w zależności od warunków klimatycznych w danym roku i od podłoża na zróżnicowanie plonowania ogórka szklarniowego. Zastosowane podłoża z wełny mineralnej Agroban i włókna kokosowego Ceres nie miały wpływu na plonowanie roślin. Natomiast istotny wpływ na plon ogólny i handlowy miało współdziałanie sterowania fertygacją z podłożem.

Opis:
Apart from the basic input, the right course of fermentation process is determined by the appropriate microorganism populations and the parameters such as: pH, particle size, ionic strength (salinity) and concentration of nutrients and toxic compounds. Three microorganism groups are involved in the process of anaerobic transformation of organic substances in fermentation gas: acid forming bacteria, acetate bacteria and methanogenic bacteria. The first two phases are dominated by the bacteria which are both obligate, facultative and absolute anaerobes (Clostridium spp., Bifidobacterium spp., Streptococcus spp., Enterobacter spp., Bacillus spp., Pseudomonas spp., Aerobacter spp., Alcaligenes spp, Escherichia spp, Lactobacillus spp, Micrococcus spp. czy Flavobacterium spp.) [Nimmrichter, Kuebler, 1999]. Their number during the mesophile fermentation is estimated for between 108-109 per 1ml [Hartman, 1999]. The rate of bacteria growth at both phases fluctuates from 5 hrs, in the presence of carbohydrates to 72 hrs during fat decomposition [Heidrich, Nieścier, 1999]. Presented research aimed at determining the quantity and quality of biogas depending on the microbiological environment in fractions originating from agriculture and agro-food industry. To achieve the objective of research, was evaluated the number and biodiversity of microorganisms that inhabit selected agricultural raw materials used in the production of biogas. A very important aspect of the study was to investigate the species composition of the bacteria and fungi population at different stages of fermentation process. Isolation of microorganisms from selected agricultural raw materials that stimulate the production of biogas could contribute in the future to optimize the process of its obtaining. The following substrates were used in the investigations: distillery’s grain, ensilaged beet pulp, rapeseed cake from biofuel manufacturing, apple pulp, fresh brewer’s grains (wet), corn silage harvested by silage harvester without grain squeezer, corn silage harvested by silage harvester combined with grain squeezer, cellulose from paper industry. Results of analysis of biogass yield in relation to dry mass revealed the highest productivity of the input from waste cellulose from paper industry at low productivity of biomass from agri-food industry. A delay in biogas volume increment visible in the course of fermentation of inputs from agri-food industry biomass is caused by the pasteurization of the mass which lacks microbiological environment, where microorganisms of methane fermentation multiply very slowly. The strongest inhibition of growth and delay in biogass formation was observed in the inputs made on the basis of distillery’s grains and fresh brewers’ grains. A normal productivity of biogass generation was obtained for the inputs prepared from cellulose and corn silage harvested by silage harvester equipped with grain squeezer.

Opis:
Gasification biochar represents one of the biochar types tested for agricultural needs. The aim of this study was to clarify the physico-chemical and biological changes occurring in a peat-sand substrate amended with hardwood-derived gasification biochar in the rates of 2, 4 and 20 g l-1. The pH(H2O) of the substrate with 4 g l-1 and 20 g l-1 biochar was increased from 5.6 to 6.2 and 6.7, respectively. The testing of the substrate in the re- spirometry device showed that the increase in the biochar rate led to a decrease in the amount of CO2 evolved at the maximum pressure drop. The continuous decrease in pressure observed in the respirometry bottles filled with pure biochar allows explaining this effect by biochar sorption activity. Addition of 2 and 4 g l-1 biochar to the peat-sand substrate stimulated the growth of cucumbers in an 18-day pot vegetation experiment. An increase in the number of root tips and root volume with a decreasing average root diameter was shown in the presence of biochar. Stimulation of plant growth on the background of low rates of biochar requires a further study with emphasis on the specific combination of biochar, soil type, plant species, and climatic conditions.

Opis:
Any type of material that increases soil yield, both qualitatively and quantitatively, to strengthen the soil and increase its fertility is called fertilizer. The current study examines the production of a new effective fertilizer. Results presented involve effects of new bioorganic-mineral compositions obtained from the combination of vermicompost and sulphur-containing waste from sulphuric acid production on the yield and quality of tubers (beets, carrots). An increase in the yield of tubers has been found to be 1.13–1.25 times when the bioorganic-mineral composition (~20 Mg∙ha–1) is introduced into the sierozem (serozem) soil. The best results are obtained with mass ratios in the range 30–45 and 55–70 for vermicompost and sulphur-perlite-containing waste, respectively. The effectiveness of the mixture of vermicompost and sulphur-containing waste is explained by the increased synergistic interaction of these components. The proposed composition has high structure-forming, water-retaining, nutritional and biologically active properties.

Opis:
Cucumber has high climatic demands especially in relation to temperature. Humidity, air temperature and UV light intensity are main factors affecting cucumber crop quality and quantity. Due to the instability of the above during the changing seasons in Poland, all-year-round cultivation of cucumber is difficult. In our experiment we used three types of substrates: rock wool, perlite and wood fibre. Cucumber cultivation was carried out in three times of the year. These two were main changing factors of the experiment. Our research proved that the best quality cucumbers was obtained in the second cultivation period – between April and August, due to the optimum climatic conditions for that species. The type of a substrate also affected the quantity of crops – the highest crops were on wood fiber, slightly lower on perlite. Higher content of dry matter, vitamin C, total sugars, calcium and phosphorus was observed in cucumber fruits from summer cultivation and a high content of nitrogen and potassium was found in cucumber fruits from autumn cultivation.
Ogórek jest gatunkiem o wysokich wymaganiach klimatycznych, szczególnie w stosunku do temperatury. Temperatura powietrza, wilgotności, oraz natężenie napromieniowania są czynnikami wpływającymi na plonowanie i jakość owoców. Zmienność parametrów w ciągu roku w Polsce utrudnia uprawę całoroczną tego gatunku. Doświadczenie prowadzono w całorocznym cyklu produkcyjnym, w trzech terminach uprawy, z zastosowaniem trzech podłoży: wełny mineralnej, perlitu, włókna drzewnego. Termin uprawy oraz zastosowane podłoże były głównymi czynnikami doświadczenia. Największe plony oraz najlepszej jakości owoce otrzymano w drugim terminie uprawy (kwiecień – sierpień) charakteryzującym się optymalnymi warunkami dla tego gatunku. Na wielkość plonowania miało również wpływ zastosowane podłoże. Największe plony otrzymano w uprawie na włóknie drzewnym, nieznacznie mniejsze w uprawie na perlicie. Największą zawartość suchej masy, cukrów ogółem, witaminy C, wapnia i fosforu miały owoce ogórka z uprawy w terminie letnim, a wyższą zawartość azotu i potasu owoce z uprawy w terminie jesiennym.

Opis:
The objective of this study was to evaluate the peat and zeolite mixtures substrates performance on cucumber seedling quality and crop yield. The research was carried out in a greenhouse covered with double polymeric film at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Cucumber seedlings were grown in different substrates: peat, peat + zeolite 1 : 1, peat + zeolite 2 : 1, peat + zeolite 3 : 1 and peat + zeolite 4 : 1. Cucumber seedlings grown in peat and zeolite substrates are shorter; the leaf area is smaller than that of the seedlings grown in peat alone. The dry mass of the aboveground part of these seedlings is lower (insignificant difference), however, the root mass is higher than those grown in peat alone. The addition of zeolite to peat substrate does not have any positive effect on the photosynthesis pigment content in cucumber seedling leaves. The physiological growth indices of the seedlings grown in peat-zeolite substrates were lower compared to those grown in peat. When zeolite is added to peat substrate, net assimilation rate is higher compared to those grown in peat. Higher yields (significant difference) were demonstrated by cucumbers, the seedlings of which had been grown in peat-zeolite substrates.

Opis:
A wide range of soilless cultivation techniques have been developed and introduced for intensive cropping systems and for boosting the crop yield of many vegetables, mainly in greenhouses. Adoption of some local natural by-products to be utilized as a substrate growing medium to overcome soil-related problems appeared to be a promising project. Therefore, greenhouse experiments were conducted at the Baloza Experimental Station of the Desert Research Center (DRC), North Sinai Governorate, Egypt, during the two consecutive winter growing seasons of 2016–2017 and 2017–2018. These experiments aimed to investigate the effects of seven growing substrate culture treatments of separated or mixed sand obtained from sand dunes and date palm tree residues (Karenna) on plant vegetative growth, flowering, fruit yield and quality traits, and fruit nutritional values of cucumber plants (Cucumis sativus L.) Filial-1 hybrid 1101. Crop evapotranspiration reference (ETc) and water use efficiency (WUE), as well as treatment feasibility, were also studied. The experiment was set up in a complete randomized block design with three replicates. The obtained results strongly indicated that growing substrate media containing 25% sand (S) from sand dunes mixed with 75% grinded Karenna (Kg) of date palm (1 S + 3 Kg) significantly recorded the superiority of all studied characters of plant vegetative growth, number of flowers, fruit set, yield and its components, as well as fruit N, P and K contents, compared with other growing substrate medium treatments. On the contrary, the worst values of all studied parameters were achieved when sand was used alone (100% S) as a growing media. Furthermore, the highest water use efficiency and net income values were also attained by the 1 S + 3 Kg media treatment relative to the other growing substrate medium treatments.

Opis:
The soilless culture of vegetables in greenhouse has increased in Turkey. In recent years, bunch tomato has grown in soilless culture. However, bacterial cancer, virus (TMV, TYLVC) andTutaabsulta are limited tomato growing soilless culture as well. For this reason, others vegetables such as eggplant and pepper can be alternative crop for soilless culture. The aim of the research is determination of growing media such as cocopeat, split mushroom compost, perlite, volcanic tuff and sawdust on yield and fruit quality of eggplant. Our results suggest that mushroom compost and cocopeat media improve eggplant fruit quality more than other growing media.
