Influence soil tillage reduced and direct seeding on winter wheat crop

Results of 2012-2013 investigation period conducting field experiment at Experimental Station of Lithuanian University of Agriculture on Calc(ar)i-Endohypogleyic Luvisol are presented in this paper. The aim of experiment is to explore the productivity of winter wheat in adapting of long duration soil cultivation. Field experiment treatments: 1. Conventional ploughing at the depth of 23-25 cm. 2. Shallow ploughing at the depth of 12-15 cm. 3. Deep loosening (cultivation with arrow-type ploughshare at the depth of 23-25 cm). 4. Shallow loosening ( loosened with arrow-type ploughshare at the depth 12-15 cm. 5. Direct seeding in uncultivated soil (sprayed with glyphosate if necessary). After 3-10 days have passed from planting, the result of germination of the winter wheat sprouts was in parallel using both methods, either operating by a simplified cultivation technique or applying the usual work in the fields. Essentially more limited (5,7%) evolution of the wheat germs was visible after 3 days of period, while applying the direct firsthand sowing. Comparing the impact on the obtained harvest, while sowing the wheat germs directly to the stubbles or sowing them to the ordinary plowed soil, no significant disparities were found. Essentially more limited (6,5%) harvest of the wheat germs was obtained while applying deep loosening up with the shallow loosening up of the groundVytauto Didžiojo universitetasŽemės ūkio akademij
