The article shows the data obtained from the study of the productivity of multispecies agrophytocenoses in the conditions of the northern region of Kazakhstan. The research methodology and findings of field experiments dedicated to the utilization of grass-legume grass mixtures to enhance pasture productivity in the northern region are detailed in this paper. It contains the meteorological data for the 2023 growing season in the northern region. The research involved agrochemical soil analyses, monitoring the density and height of the cereal-legume grass mixture, mowing and weighing, classifying the composition of the grass mixture by species, and drying bundles to reach air-dried state in order determine the productivity. The photosynthetic activity of plants was assessed by measuring chlorophyll content using the N-tester SPAD 502 Plus Chlorophyll Meter, a tool designed for on-site evaluation of plant nitrogenous nutrition based on chlorophyll content in leaves. In summary, the study suggests that selecting grass-legume mixtures with high productivity and nutritional value, adapted to the soil and climatic conditions of the northern region of Kazakhstan, is crucial for restoring pasture productivity.
