Salinity is one of the important abiotic stress affecting microorganism growth and productivity. To survive these stresses most organisms have to stress-adaptation mechanisms. It's one of these things proline. We did not find any similar studies with P. aeruginosa and E. faecalis in our studies. The highest value for proline production at 30 ?C 100 rpm was in E. faecalis 11,074 U/ml and in E. coli 6,833 U/ml. The highest proline production in LB medium containing 37 ?C 100 rpm KCl was found to be in E. faecalis 14,604 U/ml and in E. coli 6,557 U/ml. However, there are studies with E. coli. This experiment revealed that the extracellular proline concentration is proportionally linked to the KCl stress. We should first mention that studies similar to those we were less common in the literature. We did not find any similar studies with P. aeruginosa and E. faecalis in our studies. Full article

We result statistical analysis of experimental data on physical modeling of primary soil formation under long and continuous cultivation of plants on initially abiogenous mineral substrates (granite crushed stone, zeolite). The purpose of the experiment was to follow the dynamics of the evolutionary changes in the mineral substrate under condition long-term operation. We used the information approach to quantitative analyze of the relationship of primary soil formation process with the vital activity of plants (tomato, spring wheat) under controlled conditions. We analyzed the dynamics of the diversity of emerging organic matter in the mineral substrate and the biotic community. To quantify the diversity of multicomponent systems, we used information function. We have shown that the dynamics of plant productivity was statistically significant related to the parameter of information exchange between emerging organic matter and biotic community. It has been established that the increase in the total content of organic matter in the mineral substrate does not have a statistically significant correlation with the productivity of plants.

We analyze the experimental data on the dynamics of water and mineral metabolism of tomato plants by using the methods of spectral analysis. Plants were cultivated under controlled conditions. We have used the various compositions of juvenile analogues of thin-layer soil. It is shown that the composition of the soil analogue significantly affects the dynamics of water-mineral metabolism of plants and plant productivity. It was found that the dynamics of the water and mineral metabolism of plants has a clear oscillatory structure. We have identified the most intense frequencies of this process. It was found that in order to maximize the productivity of plants it is necessary that the process of transpiration should contain simultaneously both high-frequency and low-frequency periodicities. This creates the most favorable environment for the development and functioning of the plant root system. It was shown that vibrations of water metabolism closely connected with the vibrations of the content of chemical elements in plants. Full article

The effect irrigation method and tillage on yield and irrigation water productivity of rice was conducted in split plot experiment with three replications during the dry seasons 2012 and 2013 in field conditions at the Lake Geriyo Irrigation scheme farms in Yola, Nigeria. 3 irrigation management: 3, 6 and 9
The effect irrigation method and tillage on yield and irrigation water productivity of rice was conducted in split plot experiment with three replications during the dry seasons 2012 and 2013 in field conditions at the Lake Geriyo Irrigation scheme farms in Yola, Nigeria. 3 irrigation management: 3, 6 and 9 day interval with 3 tillage practices: zero, shallow and deep soil tillage were studied. Results showed that there were significant differences in paddy yield, harvest index and irrigation water productivity. 6 days interval irrigation management was placed to one group with 3 days irrigation interval on paddy yield and harvest index; higher water productivity of 3.58 and 3.51 kg ha-1 mm-1were recorded with 6 days irrigation interval in both seasons respectively. Therefore it can be recommended that 6 day interval irrigation which had better irrigation water productivity and saved up 29% irrigation water be adopted for rice cultivation under clay loam soils of guinea savanna zone of Nigeria.
