According to long-term studies of the influence of rice cultivation show that meadow-black soil, meadow, alluvial, meadow-swamp (heavy black soils) soils of the reclamation and water management complex of the Lower Kuban, with the beginning of their use for rice cultivation, lose their favorable physical properties and become degraded, merged, viscous and gleyed formations, which leads to a decrease in the yield and quality of the resulting grain, loss of soil fertility, as a rule, with the subsequent withdrawal of lands from the irrigation fund. In order to prevent these negative consequences, it is necessary to use the accumulated world experience of rice cultivation in a timely manner. For a number of reasons, many scientific achievements in the field of selective breeding and rice production technologies remain unpopular. Today, the level of information technology allows studying the advanced experience of rice cultivation in a short time. The world leader in rice production is the PRC, where for more than 10 years they have been practicing the cultivation of rice using drip watering under mulching film, considering this method to be one of the most effective and resource-saving. However, the rice-growing regions of the PRC are located in subtropical and tropical climates with the sum of active temperatures and solar activity during the growing season significantly exceeding the average values of these values for the rice-growing regions of the reclamation and water management complex of the Lower Kuban. Consequently, to implement this technology on the rice irrigation systems of the Krasnodar Territory, it is necessary to adapt them to the natural and climatic conditions of the region. Therefore, the paper proposes the technology of underground drip watering of rice, the introduction of which has proven its effectiveness and feasibility.

The world practice of rice cultivation has shown that rice cultivation by traditional methods for Russia is labor-intensive, resource-intensive, ineffective with low profitability, and often unprofitable production. As a result, traditional methods of flooding rice paddies in Russia are faced with a shortage and high cost of irrigation water and a reduction in rice irrigation systems, i.e., areas suitable for rice cultivation. For solving the problem of unprofitable rice production, an analysis of the world practice of rice production has been implemented. The analysis showed that the most optimal solution for the natural and climatic conditions of the Krasnodar Territory is the cultivation of rice using sprinkler irrigation and drip irrigation. Further analysis showed that drip irrigation is the most promising way of growing rice, which has many undeniable advantages. The main advantages of drip irrigation are the low irrigation rate, labor intensity, and energy intensity of rice production. Therefore, the article proposes a pioneering Russian ridge cultivation method for rice cultivation on the lands of the irrigated rice fund with drip irrigation under plastic and/or biodegradable perforated film. This method will make it possible to radically revise the principles of rice cultivation, form a new generation of rice crop rotations with the inclusion of melons and vegetables in them, and carry out rice production on previously rainfed lands. The implementation of the method has proven the effectiveness and feasibility of our research.

Rice Irrigation

According to the studies carried out by the US Geological Survey (USGS) under the project GFSAD30, Russia ranks fourth in the world in the number of fertile lands. However, today there are some problems that “slow down” the development of the Russia’s agricultural sector, including the rice-planting complex. One of the main problems of the Russian agro-industrial complex is unsustainable environmental management, which leads to inefficiency and sometimes loss of agricultural production. This is caused by the “rigidity” of the legal framework, the reluctance or inability of the economy to switch to new resourcesaving technologies, as well as the fear of partially or completely losing the crop when switching to new technologies. For the “soft” transition of the economy to new resource-saving technologies, we propose a resource-saving technology for cultivating rice on underground drip irrigation under mulch film on rice irrigation systems, the introduction of which proved its effectiveness, as well as the relevance of our study. The efficiency of proposed resource-saving technology of rice cultivation on drip irrigation is expressed in the increase of profitability of rice production by 26%, reduction of irrigation norm by more than 5 times, labor intensity of rice production by 42% and material costs by 24%. The proposed technology not only reduced the anthropogenic load, but also improved the land reclamation condition, including the situation in the rice irrigation ecosystem. Further development of drip technologies in the rice sector of Russia will allow developing fundamentally new, ecological-reclamative, balanced rice crop rotation with the inclusion of vegetable and cucurbits crops. The proposed technology will provide an opportunity to cultivate rice outside rice irrigation systems on previously rich lands, which will give agro-industrial workers new opportunities and prospects in rice production.

Potential Area

Rice cultivation is the most resource-intensive production in the Russian agro-industrial sector. Historically, the technology of flooded rice cultivation in thу Krasnodar Territory has remained virtually unchanged for more than 90 years. This is due not only to the biological but also to the technological features of its cultivation. In this connection, the issue of optimizing the production process of rice cultivation is becoming increasingly important every year. Global experience in rice cultivation has determined a further direction of research on optimizing rice cultivation technologies, namely the development of a resource-saving technology for drip irrigation of rice. The pioneering research done by domestic scientists to test drip irrigation of rice in Russia has proved the feasibility and effectiveness of their use. This article proposes a modern resource-saving drip irrigation project for rice, which was tested in OOO “Chernoerkovskoe” in the Slavyanskiy District of the Krasnodar Territory. The authors have proved the efficiency of the proposed rice cultivation technology, resulting in the reduction of irrigation norm, material, labour, energy and technical-technological resources in rice production and crops of rice rotation. The introduction of the new technology has improved not only the biometric indicators of rice, but also the ameliorative condition of soils. Drip irrigation technology makes it possible to cultivate rice outside the rice irrigation systems on land previously used for rain-fed agriculture, which will increase not only the potential area under rice cultivation, but also the geography of rice cultivation in Russia.

The Impact

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.

Water Management Complex

The level of the water management complex development affects the state of the resource potential of the region and its structural and sectoral features. The purpose of this article is to reveal the relations and interdependence of the processes of strategic development of the water management complex and regional economy; to form recommendations that contribute to the development of these relations. The problem of forming a strategy for the water management complex development is considered within the framework of the sustainable development concept, which takes socio-economic and environmental aspects into account. As a result of the study the influence of the water management complex on the socio-economic potential of the southern Russian regions was analyzed. Scenario variants of the water management complex development in the regions are identified, their typology is carried out. The necessity of forming a mechanism of interdepartmental coordination to improve the efficiency of the management system for the strategic development of the water management complex is justified. Conclusions are drawn about the need to supplement the basin approach to water resources management with a regional-sectoral approach. This will make it possible to link the development strategy of the water management complex with the sectoral structural changes in the region. The results of the study can be used by regional authorities and water resources management to solve the problems of increasing the sustainability of water and regional ecosystems.

Rice cultivation causes the emission of CH4 consequenced to the global warming. Reduction of irrigation in rice cultivation is not only saving water resources but also reducing greenhouse gases emission. The objectives of this study was to determine impacts of water management on the emission of CH4 and rice yield. Experiment was conducted in field conditions in An Giang province, Viet Nam with three treatments as continuous flooding (CF), An Giang Alternative Wetting and Drying (AAWD) which is mostly applied by farmers in An Giang province-Viet Nam, and Alternate Wetting and Drying (AWD). Water levels in the field +5 cm, ± 5 cm and -15 cm were controlled higher, fluctuated and lower than soil surface, respectively for CF, AAWD and AWD. CH4 emission determined every week during 13 weeks of the experiment. Rice yield was determined in 1 m2 at the end of the experiment. The results showed that AWD and AAWD, respectively decreased 78.7 % (p < 0.05) and 6.8 % (p > 0.05) CH4 emission compared to the CF 11.9 mg CH4/m2/h. The rice yield of CF was 6.32 ton/ha lower than AAWD 7.8 ton/ha (p < 0.05) but not different with AWD 6.67 ton/ha. AAWD had higher rice yield but same emission than the CF. Farmers in An Giang province should consider application of AWD in rice cultivation in term of saving water and reduction of CH4 emission.
