Abstract: For feed purposes in the production of feed barley, multi-row barley is of the greatest importance. The study of varieties of multi-row barley in the Republic of Karakalpakstan has not been carried out before. In this regard, for the development of the livestock and poultry industry, it is relevant to choose well-adapted varieties of varieties with high yields and good grain quality. The field germination of the studied varieties was approximately the same and amounted to K-713 multi-row barley: 83.8-86.0%, Productive barley 83.6-87%. Overwintering of plants on average by experience was 85.4% for the Productive barley variety, 2.8% higher for the K-713 variety line. An increase in the rate of application of mineral fertilizers for winter barley, contributed to an increase in grain yield. Thus, when applying N60P40K40, grain yield increased by 2.9 (grade Productive barley) - 4.4) c/ha (grade K-713) in comparison with the control. The most economically significant increases are noted when making N120P80K80 and N150P100K100.
Key words: winter multi-row barley, varieties, mineral fertilizers, seed germination, plant safety, photosynthetic productivity of plants, yield, crop structure.
