Published: December 2022

Abstract
The article presents the results of geobotanical studies of genus Saussurea in the conditions of the Zhongar-Alatau State National Natural Park. The lack of knowledge of the species diversity of endemic species, including genus Saussurea is an actual problem. In the Dzungarian Alatau there are more than 76 species of endemic plants, including Saussurea species listed in the Red Book. The species diversity of genus Saussurea in Kazakhstan is represented by 41 species, of which 8 species are endemic for Kazakhstan. The species diversity of Saussurea genus in the conditions of the Dzungarian Alatau, their distribution and phytocenotic characteristics were studied. The mountainous regions of Kazakhstan are characterized by a belt distribution, high biodiversity, rich vegetation and specific of flora, and on the territory of the Dzungarian Alatau, genus Saussurea is represented by 11 species, among which there are 2 endemic species (S. ninae, S. coronate), as well as 1 relict endemic (S. involucrata). It is established that a large number of Saussurea species grow at an altitude of 1600-3000 above sea level. 5 species of Saussure (S. schanginiana, S. leucophylla, S. gnaphaloides, S. sordida and S. involucrata) were found at an altitude of 2600-3200 m, which proves that these species are high-altitude.
Technology of high-yield cultivation by planting a new variety of mung bean to improve land reclamation condition, increase its productivity, and ensure ecological stability

Published: December 2022

Abstract
It is important to plant new early varieties of mung bean from leguminous crops in irrigated lands. These crops create very favorable conditions for the crops that will be planted after them. In the year following the planting of the new “Charos” variety of intensive mung bean, an additional yield of 5-7 q/ha of cotton and 7-9 quintals of grain was achieved. Therefore, when mung bean is planted as a repeated crop, the weeds in the field are reduced by 70-80 percent, while ensuring the enrichment of the soil with nutrients. In the autumn, when mung bean fields are plowed up by roots, soil fertility increases and the structure improves, as a result of raising the level of underground water to the optimal level, i.e. 2.5-3.0 meters, it was found that water-saving technologies can be widely used in planting agricultural crops. In the soil and climatic conditions of the Bukhara region, when the intensive type of mung bean “Charos” is planted, the full germination period is 5 days earlier than the Local (control) variety, 4 days compared to the Radost variety, and 3 days earlier than the Navruz variety and ripened 10-15 days earlier than Local (control), Radost, Navruz varieties. Productivity was on average 28-30 quintals per hectare, which was 6-9 q/ha more than other varieties. When this variety is planted, the stem is resistant to lying down, and until harvesting, the pods do not crack and the grain does not spill, it is very convenient to harvest with combines. For 2-3 years after planting mung bean, the use of chemical fertilizers is reduced by 25-30%, which ensures the stability of the environment and production of a clean product.

Published: December 2022

Abstract
All Over the years, due to long-term operation, the useful volume of the reservoirs decreased. Accurate assessment of the useful volume of water reservoirs, development of specific measures to prevent water wastage is one of the important issues of today. On average, 20-30% of the water volume is lost from the reservoir in one year through filtration, which is one of the main factors affecting the water wastage of reservoirs. If water waste is not taken into account, if a special volume of water is not reserved, then consumers will not be able to get the amount of water intended for them (for production purposes).
In this article, the method of calculating the volume of water lost to filtration from flow-through reservoirs is presented on the example of the Rezaksoy reservoir, and a new link on filtration calculation is proposed based on observational data obtained from field studies. The proposed calculation formula was compared with existing calculation formulas and with obtained data in natural field conditions.
Calculation of the roughness of the Sheshupe riverbed according to hydrological yearbooks
Authors: Akhmedova N R , Naumov V A 
Published: December 2022

Abstract
When conducting engineering hydrometeorological surveys, hydrological and hydraulic calculations are performed, in which an indicator characterizing the resistance of the channel to flow is taken into account. The integral characteristic of the hydraulic resistance of river channels is the roughness coefficient. In accordance with regulatory documents, the values of the roughness of the channel of the water body and the floodplain are taken according to the qualitative characteristics of the channel, which is subjective and can lead to significant errors in the calculations. The use in calculations of the roughness coefficient obtained as a result of single field measurements is inappropriate, since it can change throughout the year. This paper presents the results of studying the roughness of the Sheshupe river bed in different seasons of the year, and establishes the dependence of the roughness coefficient on dimensionless complexes (Froude and Reynolds numbers). The published data of measurements on the Sheshupe River (hydrological post in the village of Dolgoe) were used for the calculations.

Published: December 2022

Abstract
The article describes the methods of conducting some field studies to evaluate the effectiveness of sprinkler irrigation systems and to design them reliably. Also, the distribution of discharge in the irrigation system across the territory and its losses are analysed. Christiansen’s coefficient of similarity “CU” is used to estimate sprinkler water distribution. It is carried out by studying three types of combinations according to the Catch Can method: sprinkler height, sprinkler discharge and pressure changes. In order to determine the Christiansen coefficient, it is calculated using the sum of experiments in taking into account the distribution of discharge according to the height of the sprinkler at several different pressures. Based on the method given above, the optimal height was determined in the assessment of water distribution. Based on field experiments and their analysis, a graph was created based on sprinkler height and flow distribution for discharge.

Abstract
At the moment, one of the shortcomings in the management of territories where landscaping objects grow is the lack of up-to-date and reliable data, their real assessment. The reason for this lies in poor-quality accounting or in the absence of software tools for accounting for landscaping objects. In modern conditions, the availability of software tools that solve such problems most often using neural network methodologies are finding new successful applications in the practice of management and decision-making. Not only in the financial and trade spheres, but also in the field of ecology. The development of systems based on neural networks and machine learning is a necessary means of improving the efficiency of all business processes and the timeliness of management decisions. Improving the efficiency of management activities through the introduction of neural networks is becoming one of the main directions of improving the company’s activities. The problem of improving the efficiency of monitoring of landscaping facilities is solved by developing and implementing a software module using forecasting methods. Such a module will make it possible to predict the vital state of landscaping facilities and promptly identify problems of facilities and make timely management decisions in the form of proposed recommendations for their elimination based on the knowledge base of experts.

Published: December 2022

Abstract
The VP3 biofertilizer formulation begins with exploration of indigenous soil bacteria isolated from several soil samples in Malang-Indonesia. The VP3 Biofertilizer is a liquid formulation made from vermiwash and molasses as carriers, with 3 functional bacterial isolates. It has been proven to be able to increase the yield of mung beans, long yard beans, and green beans in the green house, however it has not been applied to soybean (Glycine max L.) in the field compared to other biofertilizers on the market. This study used soybean seeds of the Anjasmoro variety and consisted of 6 treatments (different types of biofertilizer) with a Randomized Block Design (RBD) namely VP3 biofertilizer, EM4 biofertilizer, Sumber Subur biofertilizer, Semanggi biofertilizer, and Magicgro G6 biofertilizer. This research was carried out in idle land. The application of VP3 biofertilizer when compared to other biofertilizers on the market generally gave better results on the parameters of growth and yield of soybeans in the field. This is indicated by the significant yield on leaf area per plant and yield of total seed weight per plot of soybean plant.

Published: December 2022

AbstractStrawberry plantlets of the ‘Earlibrite’ variety were irradiated with gamma rays to induce genetic variability for resistance to abiotic stress. This study aimed to identify the DNA polymorphism of ‘Earlibrite’ strawberry mutants using ISSR markers. For this purpose, a population of M1V0 strawberry plants was gamma-irradiated at 20 Gy. In addition, the irradiated plantlets were subcultured onto MS medium enriched with 0.13 M of 1-NAA and 2 M of 6-BAP. The genetic variation of the mutant was molecularly analyzed using the ISSR marker. Analysis was performed on M1V0 mutant plantlets. The results showed that 93.36% of 192 scoreable bands produced by the ISSR markers were polymorphic. An average of PIC values was 0.48 per primer with a range of 0.40 (ISSR_56) to 0.50 (ISSR_22, ISSR_55, ISSR_58, ISSR_60, ISSR_61, ISSR_62 and ISSR_L10). The primer MI ranged from 2.38 (ISSR_62) to 4.85 (ISSR_21). The genetic variation of mutant individuals ranged from 2.74% to 87.04% according to the Jaccard similarity index. Cluster analysis using ISSR markers grouped the ‘Earlibrite’ strawberry mutant genotypes into five distinct groups. It is concluded that 20 Gy gamma-ray induced mutation produces strawberry mutants and that ISSR was a valuable marker for mutant identification.

Abstract
The research was conducted to know the effect of several kinds of biochar on the availability of Silicon (Si) on different soils in a flooded condition. The experiment used a complete randomized design (CRD) with two factors: biochar and soil type. Biochar type consists of B1 = rice straw; B2 = rice husk; B3 = sawdust; B4 = coconut shell; B5 = corn stover. Soil type consists of T1= Inceptisol and T2 = Ultisol. Each treatment is replicated three times. The experiment used 2 kg of soil, and the dose of biochar was 5 tons.ha−1. Incubation is carried out for four weeks by maintaining a water height of 5 cm. Soil observation parameters include organic carbon, total Si, available Si, water leached Si, and pH H2O. The data were analyzed using Analysis of Variance with 95% and 99% confidence levels, Duncan’s Multiple Range Test, and Correlation Test. The results showed that rice husks biochar has a higher total Si and available Si than other biochar. Rice husk biochar gives the highest available Si of Inceptisol (8.66 mg.kg−1) and Ultisol (7.49 mg.kg−1) compared to the other biochar. Silicon leaching ranges from 5.23-8.66% of soil available Si in both soils.
