EFFECTS OF DIFFERENT TILLAGES ON SPRING WHEAT PRODUCTIVITY

Abstract

This research examines the effects of tillage intensity and straw incorporation on soil water content. The research was conducted in a long-term stationary field experiment, which is located at the Experimental Station of the VDU Agricultural Academy. The research was continued, presented in this scientific work in 2022. test results. The aim of the study is to determine and compare the influence of different tillage productivity in barley crops. The crop is spring barley (Hordeum vulgare L.). CP - conventional ploughing, DC – deep cultivation, SP – shallow plowing, SC - shallow cultivation, NT – no-tillage (in stubble with tillage up to 5 cm.).   Summarizing the effect of tillage intensity on spring barley productivity indicators, it can be said that it was different. Spring barley crop after 3 and 10 days. germination was found to be the highest in the fields where conventional tillage was applied. In fields where simplified tillage systems were applied, crop germination decreased after 3 and 10 days of counting, but no significant impact was found. Crop density increased in shallow plowed, deep plowed and shallow plowed fields, compared to deep plowed fields. The density of the crop in the direct seeding plots was very little different from that of the control variant plots. In all fields where simplified tillage systems were applied, spring barley yield decreased, but not significantly, compared to deep plowed fields.
