Aerobic rice is intensively studied in China, Japan, Brazil, India, Australia and parts of Southeast Asia and Africa. Aerobic rice is a new agronomic production system that uses less water than conventional flooded rice cultivation. Aerobic rice not only saves water and labor, but also reduces greenhouse gas emissions compared to replanted flooded rice. According to the data, water consumption in aerobic culture was about 60% less than in irrigated rice in the lowlands, the total water productivity was about 1.8 times higher, and the net return on water use was twice as high. In the past, grain yields of 5 to 6 t/ha were often reported when growing high-yielding rice varieties in aerobic rice systems. In Brazil, mountain varieties with high grain yields (from 5 to 7 t/ha) have been developed, whereas Wang et al. It was found that rice grain yields of 8 tons/ha even higher can be achieved using high-yielding mountain varieties with suitable management methods in northern China. The highest grain yield record under the aerobic rice system (11.4 t ha) was observed in Japan in 2007. The grain yield of rice varieties in aerobic culture was closely related to the water regime. The size of the panicles was considered one of the main factors limiting rice yields under aerobic conditions, since water restriction at an early reproductive stage can reduce the size of panicles by up to 40%. In a previous study conducted in Northern China, water restriction in the vegetative stages could reduce the leaf area index and, consequently, delay crown cover and reduce light absorption. All these changes contributed to the reduction of aboveground biomass in conditions of water scarcity.
Improving the efficiency of water use for rice production is the global driving force of the rice industry. Non-flooding irrigation for rice production systems is seen as an effective way to increase water productivity, especially when moving rice production to new regions with limited water supply. Although they are considered low-yielding, some adapted aerobic rice varieties can produce high yields with a high yield index when grown without nutrient deficiency and/or drought. Aerobic rice with such methods has already shown promising results with yields of 6-7 t/ha in China. Indeed, some improved aerobic rice varieties with good yields have been identified for the Huang Huai Hai River plains in China with a yield of 7 t/ha in irrigated drylands.
The difference between this project and previous studies is the transfer of foreign varieties of aerobic rice and their study in the conditions of rice growing in Kazakhstan. The effectiveness of new irrigation methods, such as drip irrigation, micro-spraying with spray tapes, and discrete irrigation for aerobic rice cultivation, will be studied. Various methods of weed control, mechanical, chemical and complex, will be studied. Based on the results of these studies, a system of aerobic rice cultivation in Kazakhstan will be developed.
The project is aimed at solving the problem of increasing the area of irrigated land in Kazakhstan by reducing the consumption of irrigation water for rice cultivation, preserving soil fertility and preventing secondary salinization of irrigated land, reducing greenhouse gas emissions into the atmosphere. Based on a comprehensive study of the features of growth and development, crop formation and product quality of rice varieties and varietals of domestic and foreign selection, the most suitable varieties for aerobic cultivation in the rice-growing zones of Kazakhstan will be selected. By laying and conducting multifactorial field experiments, basic agricultural techniques, irrigation methods and irrigation regime, methods, timing and doses of rice fertilization during aerobic cultivation will be developed. On the basis of vegetation experiments, monitoring and laboratory studies, changes in the agrophysical and agrochemical properties of the soil will be revealed, the level of greenhouse gas emissions into the atmosphere under various rice cultivation systems will be determined. The "Aerobic cultivation system in Kazakhstan" will be developed.
