EFFECTS OF SUSTAINABLE TILLAGE ON COMPONENTS OF WINTER WHEAT AGROECOSYSTEM

Abstract

A stationary experiment was set up by Prof. Dr. Vaclovas Bogužas 1999 Vytautas Magnus University ŽAA Test Station. The aim of the research - to evaluate and compare different effects of tillage on agroecosystem components of winter wheat. The research is carried out in 2019-2020. The soil in this research was Epieutric Endocalcaric Endogleyic Planosol.

The experiment was conducted with the method of field division, 4 replicates, a total of 48 fields. In the experiment, the crops are rotated in the following order: spring rape, winter wheat, spring barley. In this study, the effects of tillage systems and straw incorporation on soil components and productivity of winter wheat productivity were analysed.

The results show that simplified tillage systems and no-till showed an upward trend for soil agrochemical properties. Straw incorporation and shallow loosening before sowing, intercropping on uncultivated soil, and no-till increased soil pHKCl and mobile potassium in the soil layer.
