THE PECULARITIES OF MULTI-CROP DEVELOPMENT AND IT IS IMPACT ON THE SOIL

Abstract

The investigations were carried out in 2021 at the Experimental Station of Vytautas Magnus University, Agriculture Academy. The soil of the experimental site is silty light loam Planosol. The aim of the study was to determine the effect of crop diversification intensity on crop and soil. Methods of crop diversification were studied:

1. Maize mono-crop (KU); 2. Hemp mono-crop (KA); 3. Faba bean mono-crop (PU); 4. Maize and hemp binary-crop (KU + KA); 5. Maize and faba bean binary-crop (KU + PU); 6. Hemp and faba bean binary-crop (KA + PU); 7. Maize, hemp and faba bean ternary crop (KU + KA + PU).

No significant photosynthetically active radiation at the soil surface and at a height of 1/2 was found in mono-crop hemp (KA) and mono-crop faba bean (PU). Crop diversification did not have a significant effect on the on soil structure and soil sustainability. Chlorophyll index of maize (KU) in the binary maize and hemp crop (KU + KA), where it was insignificantly lowest, and in the ternary KU ++ KA + PU crop it was insignificantly highest.
