Effect of the Biological Preparation Phytop 8.67 on the Quality and Yield of Rice in Saline Soils

: Phytop 8.67 is a modern biological multifunctional preparation that has a complex effect on cultivated plants, harmful organisms, and soil. The study aimed to evaluate the effect of the biological preparation Phytop 8.67 on increasing yields and improving the quality of rice grains. Rice of the Marzhan variety growing on meadow/marsh rice soils was studied. The use of phytop 8.67 proved to be an effective method of increasing the productivity of rice culture in saline soils of the Kazakhstan Aral Sea region. The productivity of rice with three-time uses in the phases of vegetation in the production experiment increased by 25-30% compared to the control variants. In the field, the biological preparation provided an increase in grain yield from 20.0-25.3 c/ha. The increase in rice yield was due to the improvement of the elements of the crop structure. Pre-sowing treatment of seed material contributed to an increase in seed germination and greater plant viability by the end of the growing season. In the tillering phase, the tilling capacity of rice increased up to 2.2 times, as well as the length and the number of grains per ear of the main panicle and the weight of grain from one plant.
