Two halotolerant bacterial strains A1 and A15 of Pantoea genus were isolated from the plants growing in saline soils near the waste banks of Solikamsk technogenic biotope (Perm krai, Russia). Microorganisms were able to produce indole-3-acetic acid (IAA) from L-tryptophan and solubilize insoluble phosphates. Maximum accumulation of IAA occurred at the stationary growth phase. In the experiment with wheat seedlings inoculated with isolated strains under salt stress condition, proline concentrations in fresh weight on day 3 were 3 and 2.4 times higher than the control ones reaching 616 and 485 µg/g for A1 and A15 with 1% NaCl respectively. However the higher values of protein content in the variants with salt were achieved only within 7 days, accounting 113% and 138% of the respective total protein amount in the control with 1% of salt for A1 and A15 respectively.

On the segregated chernozem of the Central Chernozem zone, in a stationary experiment, the effectiveness of various doses of complete mineral fertilizers was studied in the cultivation of spring barley. The studies were carried out in an eight-field field crop rotation. The soil of the experimental site is segregated chernozem. It was found that the use of mineral fertilizers for the main processing improved the indicators of the effective fertility of ordinary chernozem. Their combined use with foliar feeding of spring barley plants with growth stimulants reduced the content of nitrate nitrogen at low and medium doses of NPK. An increase in the concentration of nitrogen in the vegetative mass of plants with the use of fertilizers was noted. There is a clear varietal dependence in the content of mineral elements.

Coffee is an important export commodity for the Ethiopian economy and also used for honey production. This study was aimed to identify the effect of temperature and humidity on nectar volume, the nectar secretion dynamics, honey production potentiality, and the number of bee colonies required to be placed in a hectare of coffee plantation for optimum honey production. The study was conducted in Gera District western Ethiopia. One day before nectar measuring, 5 inflorescences were covered with fine mesh bags on a different part of the tree. From covered inflorescences, twenty flowers per tree were randomly selected and nectar volume was measured using micropipettes. Accordingly, nectar volume and concentration, temperature, and air humidity were measured with an interval of one hour. The average nectar volume (µl) per flower in 24 hours, sugar amount per tree (g), expected honey yield per tree (kg) and honey (kg) production potential per hectare for C. arabica were 3.3 + 0.2, 0.040 + 3, 0.050 + 4 and 125 kg (25-275 kg), respectively. The actual harvestable amount of honey is half of the potential (62.5 kg/ha). If a kilogram of C. arabica honey would be valued at 6.25 USD, the total financial to be expected is $ 390.63 per hectare. The mean nectar volume and concentration have significant differences (p<0.05) at different hours of the day. Nectar volume was positively correlated with humidity while concentration positively correlated with temperature. One hectare of productive trees of C. arabica holds 4 or 3 or 2 honeybee colonies for traditional or transitional or frame hives respectively. From this study, it is concluded that Coffee is not economically valuable only for its seeds, but also for honey production. Therefore, the integration of coffee plantations with beekeeping is recommended.

The article presents the results of studying the dates and methods of sowing one of the most studied species Amaranthus cruentus L. for growing green mass and for grain in the soil and climatic conditions of the Chuvash Republic. For this purpose, the theoretically possible productivity of amaranth was initially found based on such climate factors as temperature conditions and moisture reserves of the growing season, and the accumulation of incoming solar energy by the crop. Further, the biological and morphological plants characteristics in different years of vegetation according to meteorological conditions were studied in field experiments and the yield of Amaranthus cruentus L. under three methods and three dates of sowing were determined. It has been established that amaranth for growing green mass can be sown in all the testing methods and at all dates, up to the end of June. The advantages of wide-row sowing methods (75 cm) and earlier sowing dates (May 25) for growing grain were identified.

Sustainable development of agriculture, increasing its productivity are inextricably linked with the intensification of the industry and the growth of its efficiency. One of the most important intensification factors is the use of a fertilizer system. The fertilizer system includes the selection of the best combinations of various types, forms and doses of fertilizers, applied at the optimal time and providing the maximum increase in yield from fertilizers directly in the year of use. At the same time, it should be noted that the most positive effect of fertilizers is manifested in the case when their use is put on a scientific basis, depending on the biological characteristics of the culture, variety and soil and climatic conditions. The correct use of fertilizers should be economically profitable, ensure the production of more high-quality products with relatively less additional costs of production means and labor. Field experiments are often a long-term and costly undertaking. In order to eliminate these shortcomings, they resort to using economic and mathematical methods in the practice of an agrochemical experiment to optimize the fertilizer system.

The paper examines the possibility of using drilling wastewater in the remediation of disturbed land. The samples were examined using concentration meter, spectrophometer, and pH meter. Studies on the metal content were carried out by atomic emission spectrometry with inductively coupled plasma. It was found that the liquid drilling waste contains a complex of biophilic elements: N, Ca, Na, K, P, S, Cl, Fe, Cu, Co, Mn, Zn. Three soil plots for sowing grasses on liquid drilling waste were studied. The soil was furrowed and the grass mixture was sown using working solutions. The possibility of using drilling wastewater as a meliorant in the conditions of forest-tundra and tundra zones of the Krasnoyarsk Territory has been established. The results of experimental data indicate that the use of components of liquid drilling waste in the formulation of agrochemical preparations does not have a negative effect on seed germination and plant growth.

This article evaluates the content of mercury in various tissues (gills, mantle, hepatopancreas, and body "foot") in four species of bivalves in the estuary area of the Red River in Vietnam. In this article, the authors determine the dependencies of the mercury content in the tissues of mollusks on the indicators of the length and mass of tissues and on the content of the pollutant in dissolved, suspended forms and in bottom sediments. The content of mercury in the tissues of mollusks varies from 30.5±1.2 to 415.8±6.3 ng/g. The highest content of the toxicant was observed in the hepatopancreas of Austriella corrugate, while the lowest was seen in the “foot” of Lutraria rhynchaena. Close, reliable, positive correlations between the concentration of mercury in the tissues of mollusks and the contents of its suspended form in the bottom water layer and in bottom sediments (r from 0.68 to 0.92, p <0.05) were observed. Bivalves can be used as one of the objects of biomonitoring when studying the distribution of mercury in the estuary area of the Red River.
