RESULTS
In the laboratory conditions, influence of the substrate based on brown coal and natural zeolite (clinoptilolite) on the biometric parameters of barley germination has been investigated. The following biometric parameters have been determined: germination energy (GE), relative value of germination energy (RVGE), germination (G), relative value of seed germination (RVSG), height of sprout (HS), relative size of height of sprout (RSHS), rate of germination (RG) and intergrowth (IG).
As it is seen, introduction of zeolite into the soil has an essential influence on the calculated parameters, raising their values by 2 % and higher. These parameters are even higher for the samples containing zeolites and brown coal. Variation of these parameters on the substrate occurs in the sequence:
soil (object of comparison) <soil+brown coal <soil+zeolite< brown coal+zeolite < soil+zeolite+brown coal.
Relative germination of seeds of barleys (RGBB), were calculated by the formulas:
RGBB %= (NGex - NGc / NGc)x100
Where, NGex – number of germination in the experimental version; NGc – number of germination in the control version
CONCLUSION
It’s shown that the enrichment of the soil with zeolite in combination with brown coal substantially raises germination and development of the seeded cultures. In addition, the presented work has preliminary character and the results provide a basis for experiments in the field, as well as more detailed agrochemical research for the examined substrates.
At peasant, experience for application of such untraditional natural resources as zeolite, pearlite and other mineral materials in plant growing has accumulated in our country as well as in abroad. But in spite of the researches in the field of the application of natural zeolites, lots of the problems have not been studied yet that makes our project, directed to the production of high yield, quality, and ecologically safe products, actual. Introduction of such useful materials into soil has a positive effect on germination of cereal crops and vegetable.
Humic substances rich brown coal for use in crop production is confirmed by numerous investigator. The deposits of brown coal in Georgia (Samtskhe Javakheti; Kakheti; Samegrelo) enable their application as the source for humic compounds.
MATERIALS AND METHODS
According to the above, we consider it reasonable to study the effects of the bioactive organo-zeolite fertilizers (substrates) prepared on the basis of brown coal and natural zeolite on the bio-productivity of the agricultural crops. The effect of such the bioactive fertilizer is caused by a prolonged transfer of humic compounds (existing in brown coal) to a plant by means of zeolites and maintain all their useful properties at the same time.
The experiment was carried out in the vegetative vessels, in three versions, each in three replications. For testing the fertility of the substrate, barley - “Alaverdi 1” were used as the test plants.
