There was described the history of rice growing branch formation on Kuban from thirties to eighties of XX century: from first sowings to the production of a million ton of rice. The role of academician E.P.Alyoshin in the development of Kuban rice growing was marked. There were shown the ways of rice harvest increase on Kuban at present time

CJSC Priazovskoye located in the Slavyansk district is in the area of the Priazovie marshes. Soil and climatic conditions make it possible to grow many heat-loving crops including rice. The farm specializes in the cultivation of rice and the production of meat and cattle dairy products. The rice system is divided into 8-crop rotations, where, in addition to rice, animal feed is grown. Livestock waste is used as organic fertilizer in the fields of crop rotation. In the field experiment with perennial grasses (alfalfa) as predecessor, the change in yield and seed quality of three rice varieties Rapan, Diamant and Flagman was studied. The rates of the applied fertilizers were: phosphorus 100 kg/ha, potassium 60 kg/ha and increasing rates of nitrogen from 30 to 120 kg/ha. It has been established that the optimal rates of nitrogen fertilizers after alfalfa are 90 kg/ha (a.i.) for Rapan and Diamant varieties and 60 kg/ha (a.i.) for Flagman. At the same time, the maximum grain yield was obtained for Rapan - 7.45 t/ha, Diamant - 8.27 t/ha, Flagman - 7.62 t/ha , and the best seeds were formed in terms of germination and emergence. Analysis of the crop structure of rice varieties showed that with increasing rates of nitrogen the productive tillering and grain mass per panicle increased. With the nitrogen rate higher than the optimum, the number of unfilled grains per panicle and the grain /straw ratio have increased. Based on this analysis, it can be considered that the number of unfilled grains per panicle and the grain /straw ratio can serve as indicators of the response of rice plants of these varieties to an excess of the optimal level of mineral nutritions
