The increasing need to enhance the efficiency of brewing barley cultivation, a key crop for brewing and food industries, is critical amid climate change, unstable moisture, and soil resource depletion. This study scientifically evaluates optimal agronomic practices—specifically sowing dates and seeding rates—tailored to the soil and climatic conditions of the Balkhash district, Almaty region. Multi-year research on the brewing barley variety "Arna" assessed the impact of sowing timing and seeding density on plant growth, phenology, productivity, and grain quality. Results showed that early sowing with a seeding rate of 5.0 million viable seeds per hectare fosters strong seedling establishment, optimal development, and high yields reaching 30.1 centners per hectare. Increasing seeding rates from 2 to 6 million seeds per hectare raised productive stem counts from 300 to 460 per m² but reduced productive tillering, indicating plant compensatory responses.Correlation analysis revealed a strong positive relationship between grain number per spike and spike productivity (r = 0.977) and a negative correlation between productive tillering and seeding rate (r = –0.847). Grain quality at the optimal seeding rate (5.0 million seeds/ha) was characterized by high test weight (up to 654 g/l), grain size (up to 85%), germination rate (up to 95%), husk content (~9.5%), protein (~11.6%), starch (up to 61.3%), and extractivity (up to 76.1%). Although increasing seeding rate to 6.0 million seeds/ha improved yield and thousand-kernel weight, it lowered protein content.These findings underscore the importance of a comprehensive, locally adapted approach to sowing dates and seeding rates to maximize yield and grain quality of "Arna" brewing barley. The recommended agronomic practices produce grain meeting GOST 5060-86 standards, supporting regional brewing industry development. The results provide valuable guidance for optimizing brewing barley cultivation technologies under regional conditions.
