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
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
