Productivity of spring barley in the conditions of the Altai territory

The article presents the results of studying the productivity index of barley varieties. The average yield of varieties for four years of research was 2.87 t/ha. The tested varieties were, in terms of yield, at the standard level (2.7 t/ha): Spool, Quiver, Gift of Siberia, Aley, Kedrovich other varieties significantly exceeded the standard for this indicator. Signs of high positive correlation (r > 0.7) are: "yield" and "productive bushiness" (r = 0.8192), "ear length" and "plant height" (r = 0.8187) at the confidence threshold: at the level of 5%: R = 0.6021
