The Biological Method of Increasing Seed Germination and Productivity of Grain Crops

The aim of present paper is to study the antifungal activity of the new platinum, palladium and copper chelate complexes with different organic ligands against Fusarium strains and to determine the influence of these compounds on the germination energy and seed germination of investigated grain crops. Methods. In vitro antifungal activities of new chelate complexes were studied by the agar disk diffusion method. New complexes were tested against pathogenic Fusarium strains such as — F. culmorum 3260/4, F. verticillioides and F. sporotrichioides. The toxic effect of new complexes was evaluated according to changes in germination power and seed germination of grain crops — winter wheat, vernal barley and maize. The determination of these characteristics was carried out in accordance with the standard demands. Results. Our results revealed that palladium complex H exhibited fungicidal activity against F. culmorum 3260/4 and fungistatic activity against F. verticillioides with growth inhibition zone diameter 25 mm ad 20 mm respectively. Copper complex 2 showed a moderate fungicidal effect against F. culmorum 3260/4 strain (inhibition zone diameter 12 mm). The treatment of grain crops seeds with the H and 2 complexes demonstrated the less toxicity than standard agent — commercial fungicide tebuconazol. These complexes had also less negative influence on the germination power for all test cultures than tebuconazol. Copper complex 2 showed a noticeable growth promoting effect on studied seeds compared to seeds under conditions without treatment. Conclusions. Thus, the studied complexes can be considered as promising antifungal agents with growth regulating properties. The directional modification of the complexes to obtain the more potent derivatives will be performed.Keywords: metal-organic compounds, antifungal, growths regulation activity.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.
