EFFECT OF INNOVATIVE BIOLOGICAL FERTILIZERS NACLE AND PHYTOP 8.67 8 ON RICE YIELD WHEN GROWN IN KAZAKHSTAN ARAL SEA REGION

Abstract

The use of biological fertilizers in agriculture is becoming increasingly popular in many countries, but very little research has been done on their effect on grain yields in rice production. The article presents the results of a study on the use of complex liquid fertilizers and biological preparations to increase the yield of rice in the conditions of the Aral Sea region. The purpose of the study is the use of complex liquid fertilizers, biological preparations and the analysis of agroecological efficiency for rice growth in the conditions of the Aral Sea region. We conducted field experimental studies to determine the agroecological effectiveness of the use of complex liquid fertilizers, biological preparations and their effect on increasing rice yields. The productivity of rice was determined by the indicators of the crop structure and was characterized by fairly high correlation coefficients with them. It was found that pre-sowing seed treatment with mineral fertilizers and fertilizing with biological preparations significantly affected the crop yield, which varied 3,9-5,7 t/ha depending on the variant. The yield of rice of the «Syr Suluy» variety increases during presowing seed treatment and fertilizing with biological preparations Nacle and Phytop 8,67 by 0,2–0,3 t/ha, and when used together with a full mineral fertilizer - by 1,9-2,0 t/ha. In this regard, we recommend the complex use of the biopreparations Nacle and Phytop 8,67 with mineral fertilizer.
