EFFICIENCY IMPROVEMENT IN THE NATIONAL RICE BREEDING AND SEED PRODUCTION
Description
The article reviews economic aspects of efficiency improvement of the national breeding capacity in rice growing. It is noted that there are no foreign rice varieties in the RF State Register of Breeding Achievements approved for use. However, only 2 - 3 leading rice varieties cover more than half of the rice acreage and thus reducing the efficiency of the existing varieties potential of the economic sub-sector. The critical importance of breeding and the wide-spread introduction into production of rice varieties resistant to disease is highlighted. The cyclic and growing occurrence frequency of blast as the most harmful disease of rice is shown. The data are provided on the increase of the annual cost of the rice crop and fungicide treatment and reduced yields of different varieties of rice during epiphytoties. A refined formula is proposed for calculating the annual economic effect of the introduction of new rice varieties. The formula takes into account changes in yield components, grain quality, the cost of breeding and introduction of new varieties, as well as the potential cost savings due to rice resistance to blast. The seeds of domestic long-grain rice varieties and exclusive varieties resistant to blast are available for the Russian market. For a wider introduction into production of all local bred rice varieties, it is necessary to actively develop seed production, improve market research as well as the management efficiency in plant breeding and seed production

THE ECONOMIC EFFICIENCY OF INTRODUCTION OF NEW RICE GROWING AGRICULTURAL PRACTICES
Description
The article describes historical and economic aspects of the rice industry evolution in the Krasnodar region. The basic means of increasing the economic efficiency of rice production are demonstrated: reduction of production costs and growth of profitability. The role of new agricultural practices aiming at optimization of rice mineral nutrition is highlighted. The data are provided on the economic impact of liquid nitrogen fertilizers and application of new micronutrients in rice crops. It is shown that the use of liquid nitrogen top-dressing in rice crops leads to reduction of costs by 1000 rubles/ha compared to traditional practices. The effectiveness of micronutrients application on rice has been confirmed experimentally by the use of water-soluble fertilizer Poligro Bits. According to the received data the yield increase in the rice varieties Khazar, Rapan and Diamond was 0,53-1,33 t/ha with improved grain quality. Calculations show the economic feasibility of the introduction of this practice. Based on the research results the recommendations have been issued on the improvement of rice production and its economic efficiency. Among them is the use of modern agricultural practices, introduction of new rice varieties, innovative optimization methods of rice mineral nutrition, upgrading of rice farmers’ skills, introduction of marketing structures for rice farms
