Abstract An assessment of the influence of electrotechnology of ultraviolet irradiation of seeds and pre-sowing soil treatment and the creation, on their technological basis, of management and control of salt and nutritional regimes of irrigated soils has been carried out. Relative yield of field crops versus the concentration of toxic salts in the soil solution at full moisture capacity are shown. By results of experimental researches acting of UV irradiation on the amount of ammonifying bacteria in the soil under cotton for increasing the accumulation of the most mobile nitrate forms of nitrogen are defined.

Cuscus is an arboreal animal whose habitat is in the forest with the type of food consumed are fruits, leaf shoots, and agricultural plants. Animal manure can also be used as organic fertilizer for forage plants. This study aims to determine the growth response of Setaria grass (Setaria sphacelata) given a dose of cuscus manure fertilizer with banana and avocado consumption. The study was designed in a CRD with 3 treatments. The treatments were P0 = without fertilizer (100% soil), P1 = 40 g/polybag of cuscus manure with banana consumption, and P2 = 40 g/polybag of cuscus manure with avocado consumption. Planting is done by pols on polybags measuring 30 x 25 cm. The results showed that the highest plant height of Setaria grass was found in P2 with an average of 101.70, then P1 was 101.47 and P0 was 71.16 cm/week. The results were the same for the number of leaves and tillers, P2 showed significantly higher results (P<0.05), followed by P1 and control. The application of organic fertilizer of cuscus manure with the consumption of bananas and avocados can increase the growth of Setaria grass.

Irrigated Soils

A study using 15N~labelled fertilizer was initiated in a lysimeter facility to quantify the amount of N assimilated by maize plants and that which remained in the soil at the end of a cropping season. Maize was planted in 0.43 m2 by 1.35 m deep intact Marah clay loam soil cores removed from an improved pasture in mid-October 1983. Two irrigation treatments, flood-impounding water on the soil for up to 72 h, and control-applying enough water to prevent plant stress without ponding, were employed. The crop was harvested in early April 1984 and the amount of fertilizer- and soil-derived N in the plant and remaining in the soil was determined. Grain yields were reduced about 33% by flood irrigation. Although about 30 kg N ha-1 more fertilizer N was lost from the flood-irrigated system, the difference in N recovery between the flood- and control-irrigated soils was not sufficient to account for the reduced grain yield. Flood-irrigated plants were less efficient in transporting fertilizer N to the seed than were control irrigation plants. The data suggest that the reduced seed yield and total N content of maize plants grown under flood irrigation was metabolically controlled rather than being derived from a difference in soil mineral N content compared with control-irrigated soils.

The technology of electro-processing by UV-radiation soil of agricultural plants is considered. The mechanism of the effect of UV irradiation to change by redox reactions a chemical potential of the soil is shown. As the result of experimental researches, optimum parameters for processing soils with ultraviolet radiation lamps for increasing the absorption of the most mobile manganese forms in plants are defined.

The greenhouse whitefly (Trialeurodes vaporariorum Westw.) is one of the most important pests met in protected spaces, determining major damages to vegetables crops and also to the flower crops. this pest, besides the damage it determine in greenhouses crops, in hot years, during summer, it also can be seen in field crops, where it produce great damage by stinging and sucking the cell juice from the leaves tissues and young offshoot of different crop plants. Researchers all over the world where this pest has been seen were and still are preoccupied by all the aspects concerning its origin, spreading areas, morphology, biology and control. The present paper propose a study f the morphology of the egg and larvae of this dangerous pest and the completition of the dates already known with the photos taken at the Center of Electronic Microscopy at Babeş-Bolyai University in Cluj-Napoca.

Nematic liquid crystal planar and smoothly-irregular waveguide structures were studied experimentally and by the computer modeling. Two types of optical smoothly-irregular waveguide structures promising for application in telecommunications and control systems are studied by numerical simulation: liquid crystal waveguides and thin film solid generalized waveguide Luneburg lens. Study of the behavior of these waveguide structures where liquid crystal layer can be used to control the properties of the entire device, of course, promising, especially since such devices are also able to perform various sensory functions when changing some external parameters, accompanied by a change in a number of their properties. It can be of interest to researchers not only in the field of the integrated optics but also in some others areas: nano-photonics, optofluidics, telecommunications, and control systems. The dependences of the attenuation coefficient (optical losses) of waveguide modes and the effective sizes (correlation radii) of quasi-stationary irregularities of the liquid-crystal layers on the linear laser radiation polarization and on the presence of pulse-periodic electric field were experimentally observed. An estimate was made of the correlation radii of liquid-crystal waveguide quasi-stationary irregularities. The obtained results are undoubtedly important for further research of waveguide liquid crystal layers, both from the theoretical point of view, and practical – in the organization and carrying out new experimental researches, for example, when developing promising integrated-optical LC sensors.

scholarly journals At the moment, complex and unified solutions have not been created, with the intensification of processes and control systems in accordance with integral resource-efficient criteria, which increases the urgency of the task of developing a technological basis for a specialized combined electrotechnological complex for water treatment. The aim of the research is to substantiate the structure and parameters of the combined electrotechnological processes of wastewater treatment in paper and cardboard production. When treating wastewater, electrocoagulation processes were used, characterized by the electrochemical dissolution of metal anodes. Also, during the processing, chemical coagulation was used, which is based on the addition of active coagulants to the wastewater: ammonium, copper, and iron salts. To accelerate the precipitation processes, after coagulation, a biocidal flocculant was used, after which the clarified solution was passed through a diaphragm electrolyzer with an inactive membrane. Also, wastewater was subjected to ozonation for the purpose of additional oxidation of pollutants. To mix the coagulant and effluents, we used an atmospheric air supply. After flotation coagulation, the wastewater was separated by sedimentation and filtered, if necessary, through a polystyrene foam filter. After evaluating the results of experimental wastewater treatment of paper and cardboard production, a combined scheme of an electrotechnological water treatment complex is proposed. Calculation of technical and economic indicators showed that the financial costs of processing glue and dye washes using a combined electrotechnical complex are almost six times less than the services of specialized companies for the disposal of such wastewater. Disposal of untreated aqueous solutions of paper and cardboard production without purification is unacceptable - from the point of view of their possible critical anthropogenic load on the environment in such cases.
