"STUDY OF PEA VARIETIES UNDER THE CONDITIONS OF NORTHEASTERN KAZAKHSTAN"

The article presents the results of ecological variety testing of seeded peas conducted at experimental sites in the north-east of the Pavlodar region. The study involved 5 varieties of seeded peas. The assessment was carried out according to economically valuable and morphological characteristics. Experiments have shown high adaptability of the studied varieties to local climatic conditions and soil type. The average duration of the growing season of the studied cultivars was 78–84 days, with the exception of the ultra-early cultivar Kasib, which had a growing season of 65 days. The Ruslan variety showed the highest yield – 17.8 c/ha with a mass of 1000 seeds of 254.6 g and a protein content of 2.41 %, surpassing other varieties in terms of aggregate indicators. The tested cultivars, adapted to a short growing season, meet the requirements of the state standard and can increase the efficiency of feed production and solve the problem of protein deficiency in animal husbandry. High indicators of varietal samples confirm their importance for improving soil fertility and ensuring consistently high yields in the region, which contributes to food security and the maintenance of sustainable agricultural production. The results obtained confirm the need for further research in this priority and promising area. Keywords: ecological sorting test, peas, yield, protein, adaptability, sustainability, Pavlodar region.
