Antibacterial activity of aromatic plants essential oils from Serbia against the Listeria monocytogenes

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4,5)

Abstract:

The purpose of this study was to examine the effectiveness of selected essential oils for the control of the growth and survival of pathogenic bacteria Listeria monocytogenes ATCC 19112 and Listeria monocytogenes ATCC 19115, which are of significant importance in food hygiene. Essential oils extracted from Salvia officinalis L., Rosmarinus officinalis L., Majorana hortensis Moench., Thymus vulgaris L., Carum carvi L., Pimpinella anisum L. and Coriandrum sativum L. were evaluated.

Effect of different doses of slow-disintegrating fertilizer on the quality of impatiens' seedlings (Impatiens walleriana L.)

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)

Abstract:

The paper studies the effect of applying different doses of slow disintegrating fertilizer 'Scotts' ( Osmocote Exact ) of the formulation 15:9:9:MgO + Me to the quality of impatiens seedlings. The impatiens' seedlings were produced in poly-styrene containers ( speedling system ) and poly-propylene pots ( pot system ). During the seedlings' production, the fertilizer was added in different doses (0, 1, 2, 3, and 4g/l ).

The effect of natural biostimulators and slow-disintegrating fertilizers on the quality of rosemary seedlings (Rosmarinus officinalis L.)

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)

Abstract:

In the present work the effect of natural biostimulators and different doses of slow disintegrating fertilizer on the quality of rosemary seedlings was studied. Rosemary seedlings were produced in containers, according to the 'speedling system'. During the production of seedlings natural biostimulators Megafol and Viva and microbiological fertilizer Slavol were added. The applied biostimulators made a significant effect on the quality of rosemary seedlings.

Effect of applying different rates of slow - disintegrating fertilizer on the quality of marigold (Tagetes patula L.) and scarlet sage seedlings (Salvia splendens L.)

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)

Abstract:

The paper investigates the effect of applying different rate of slow disintegrating fertilizer Scotts (Osmocot Exact) with the formula 15:9:9:MgO+Me to the quality of seedlings of marigold and scarlet sage. The marigold and scarlet sage seedlings were grown in poly-propylene containers (speedling system) and poly-propylene pots (pot system). Slow disintegrating fertilizer rate have been applied to the seedlings in the course of their growing (0, 1, 2, 3, i 4 g/l).

Salt tolerance of corn genotypes (Zea mays L.) during germination and later growth

Institute of Field and Vegetable Crops, Novi Sad (1,3)
Faculty of Agriculture, Belgrade-Zemun (2)

Abstract:

Since corn is grown in climatically diverse regions and under different production conditions, assuming that high salinity in the substrate affect corn seed performance, such conditions were simulated in this study in order to examine their effects on seedling geminability and length in several corn genotypes. The study showed that the tested seeds tolerated the stress conditions up to a certain point. The studied genotypes differed in level of resistance to the stress conditions.

Influence of slow disintegrating fertilizer rates on quality of gazania (Gazania rigens L.) seedlings

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)

Abstract:

The work has examined the influence of slow disintegrating fertilizer rates of Scotts (Osmocote Exact) formulation 15:9:9:MgO + Me on quality of Gazania rigens L. seedlings. The seedlings of Gazania rigens L. was produced in polystyrene containers (speedling system) and polypropylene pots (pot system). During the production of seedlings the fertilizer has been applied in rates (0, 1, 2, 3, and 4g/l). The results show that the fertilizer rate of substrata 4g/l influences the qualitative properties of Gazania rigens L. seedlings.

Effect of natural bio-stimulant and slow-release fertilizers in commercial production of begonia sapling (Begonia semperflorens)

Faculty of Agriculture, Belgrade-Zemun (1,2,4,5)
Faculty of Arboriculture, Belgrade (3)

Abstract:

The present research in the study of the effect of application of natural bio-stimulants and slow-release fertilizers on commercial production of begonia (Begonia semperflorens) saplings. Two types of containers were deployed in the production process, whereas the results of the experimental research showed that the application of both slow-release fertilizers and natural bio-stimulants in further production is only justifiable in cases when large volume containers are deployed in commercial production of sapling.

Effect of greenhouse conditions on Zn, Fe and Cu content in tomato fruits

Faculty of Agriculture, Belgrade-Zemun (1,2,3)

Abstract:

Tomato investigations were carried out under greenhouse and field conditions. The aim was to determine the extent to which greenhouse conditions influence the chemical composition of tomato fruits. Plants grown under field conditions were used as the control. Tomato trials were performed during different periods. Greenhouse trials were carried out in the winter and the spring period (January-June), and field trials in the spring and the summer period (May-September). Zinc (Zn), iron (Fe) and copper (Cu) content was established in ripe tomato fruits.

Effects of different substrates on basil seedlings quality (Ocimum basilicum L.)

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)

Abstract:

In this study five different substrates were used, such as: compost; mixture of compost, Lumbrikus H and garden soil; mixture of compost and Lumbrikus H; mixture of compost, Lumbrikus H and peat Galicina and Seedling Klassman substrate. Basil seedling was produced in containers according to "speeding" system. The studies have shown that the best quality of basil seedling of varieties Genovese and Lattuga is achieved when the mixture of substrates Compost, Lumbrikus H and Galicina peat are applied in the volume proportion of 50% : 30% : 20%.
