Using the matrix of growth it is possible to examine, in a specific way, structural relations of growth in order to discover the mutual influences of activities and their linking into systems. Considering that different sorts of meat can substitute one another in nutrition, during the observation of the dynamics of the consumption of a certain sort of meat, its change should be observed as a function of a scope of the consumption of other sorts of meat in the analyzed time period.

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 ).

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.

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).

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.

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.

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%.

Efficacy and profitability of results and eventually the conclusions of an experiment were found to depend on the statistical model for organizing an experiment. No thoroughgoing studies have been reported to date in our statistical literature on Latin square designs, one of the three basic experimental designs.

Marketability of livestock production was analyzed based on the marketability of both pork, beef, sheep and poultry and eggs and cow's milk. The sequential order of the Vojvodina municipalities according to the observed denominators is not identical. But, Spearman's coefficient of correlation points to a statistically very high degree of accordance between the rank-list of marketability of pork and the rank-lists of marketability of beef, poultry and milk as well as the rank-list of poultry and sequential classification of sheep meat and eggs, beef and milk.

Using the autoregression models, the paper considers movement of agricultural population. Irregular movement of agricultural population can be analyzed within the formal framework of the chaotic growth model.
