Influence of the year on the productivity of alternative cereal spelt on degrade soil

In the last forty years, about 30% of agricultural soil has undergone degradation processes, especially in developed countries. There are attempts to repair or recultivate degraded soils, but the results both in the world and in our country are mostly symbolic. Spelt achieves good results on degraded soil. It is more and more cultivated, because spelled grain has a high protein content, up to 25%, more proline, tyrosine, glutamic and aspartic acids, lipids and unsaturated fatty acids from common wheat. It is resistant to low temperatures, diseases and pests and suitable for organic production. The paper presents the results of two-year tests on the spelt productivity grown on degraded soil. The average value for grain yield in the examined years was 3.951±0.53 t/ha. The Nirvana variety had a statistically significantly higher grain yield in 2020 (4.40±0.10 t/ha) compared to 2021 (3.50±0.30 t/ha). Positive and very strong correlations were found between grain yield and volumetric mass (r=0.97*) and a strong positive correlation between yield and mass of 1000 grains (r=0.67*)
