These are interested infinding the proper solutions for the insurance of the best growth conditions for the plants. Fertilizers are indispensablefor success of the type of culture at high parameters.Researches have been done at the Fruit Research DevelopmentConstanta between 2004-2006.The biological material used for studies was represented by plants of Thuja OccidentalisColumna. Substratum for culture, resulted by mixing some compounds, were represented by: Substratum 1 made by:ground celery, ground leaf, peat and sand 1:1:1:0,5; Substratum 2 made by: forest compost and perlit 3:1.Experimental scheme included 6 variants: 2 controls unfertilized, with plants cultivated in the two substratum; 2variants with substratum fertilized with forest compost NPK 15:15:15; 2 variants fertilized during vegetation with Coïcnutritive solution. There were organized (6) six variants with four (4) replications. During the three years of studies hasbeen done agrochemical analysis of substratum from containers, in May and in September, to establish: pH; totalnitrogen; humus %,; organic substance; phosphorus; potassium. The observations made on the plants consisted in:biometric measurements of the plants in May and September regarding: height of plants (cm), trunk thickness diameter(mm), number of offshoots; agrochemical analysis for finding the provisioning level in nutritive elements of the plants.The best substratum for Thuja Occidentalis “Columna” was represented by substratum 1 with complex fertilizer (NPK)15:15:15 applied 5 kg/mc before planting in containers. Substratum 1, fertilized before planting in containers leaded tosignificant growth. Coïc solution applied during vegetation had also considerable influence on plants growth.Key words: complex fertilizer, nutritive solution, substratum.INTRODUCTIONThe containerized culture of the ornamentalplants has an increasing importance forproducers. These are interested in finding theproper solutions for the insurance of the bestgrowth conditions for the plants.Fertilizers are indispensable for success of thetype of culture at high parameters, so that it isnecessary to solve the aspects of using them.MATERIALS AND METHODSResearches have been made at the FruitResearch Development Constanta between2004-2006. The biological material used forstudies was represented by plants of ThujaOccidentalis Columna, multiplied before bycuttings. Substratum for culture, resulted bymixing some compounds, were represented by:-Substratum 1 made by: ground celery, groundleaf, peat and sand 1:1:1:0,5.-Substratum 2made by: forest compost and perlit 3:1.Experimental scheme included 6 variants: -2controls unfertilized, with plants cultivated inthe two substratum; -2 variants with substratumfertilized with forest compost NPK 15:15:15; -2 variants fertilized during vegetation with Coïcnutritive solution. There were organized (6) sixvariants with four (4) replications. Eachreplication included three plants. Plants ofThuja were planted in containers with 12 cmdiameters.Analyses and observationsSubstratum.During the three years of studies has been doneagrochemical analysis of substratum fromcontainers, in May and in September, toestablish the following parameters: pH (inwater) – potentiometer; total nitrogen (N), byKjeldhal method; humus%, by Walklay Blackmethod (modified by Gogoaa); organicsubstance%, by wet combustion method;phosphorus (P), ppm in Al, by Egner – RhiemDomingo method; potassium, ppm in Al, byflame photometry. Biological material. The309
observations made on the plants of Thuja fromcontainers consisted in: -biometricmeasurements of the plants in May andSeptember, for every vegetation cycle,regarding:-height of plants (cm) -trunkthickness diameter (mm) -number of offshootsagrochemicalanalysis for finding theprovisioning level in nutritive elements of theplants which were made in May and Septemberto determine:-N%, by Kjeldhal method-P%, bywet mineralization and colorimetric dosage-K%, by wet mineralization and flamephotometryRESULTS AND DISCUSSIONSIn table 1 are presented the effects of differentnutrition of the plants about the height, trunkthickness diameter and number of offshoots.Table 1. Biometric determinations of Thuja occidentalis " Columna"Table 1 shows that the best results wereregistered at fertilized variants, in substratum 1:22,6 cm increase growth for fertilizing withNPK and 2,9 cm for nutritive solution.Number of offshoots was also bigger in thesevariants towards of unfertilized control andvariant from substratum 2, with lightcomposition.Statistic interpretation of the results of thebiometric measurements are included in table 2and figure 1.Table 2.
