INFLUENCE OF THE TIMING OF INTERMEDIATE (INTERCROPPING) ON SOIL, SPRING BARLEY DEVELOPMENT AND PRODUCTIVITY

Abstract

The cultivation of intermediate crops affects the agrochemical properties of the soil and the productivity of the crops. Studies on the benefits of intermediate crops are still insufficient and a more in-depth analysis is needed. To solve these problems, the study was carried out in Šiauliai district, at the entrances of Šakyna town in 2020-2021. The aim of the studies is to determine the impact of the time of insertion of intermediate crops on the structure of the soil and on the productivity and development of malting barley. The field experiment contains two factors, four options: 1. Disked once (disked in spring) and sown the spring barley variety 'Laureate'; 2. Disked once and sown spring barley variety 'RGT Planet'; 3. Disked twice (autumn and spring) and sown spring barley variety 'Laureate'; 4. Disked twice and sown the spring barley variety 'RGT Planet'.

The results of the study showed that the intermediate crop stored during the winter had a positive effect on the soil and the crops that grow after them. In the soil of the field experiment before spring tillage, the structure of the mess was dominated by the structure of the meso, which stood out at the very lowest percentage of aggregates. boxes in shavings twice, so according to the mega structure made up almost 30% of the units.

The moisture content of the soil was substantially lower in the fields of disked in autumn and spring. Higher humidity was in the fields in the disked once, so elementary barley sprouted better in these fields. Exactly less sprouted fields, which were disked twice, and the choice of variety did not affect the germination of barley. The maximum mass of 1,000 grains was in fields that were disked twice.
