Abstract
The humidity of the soil and the quality of seedbed preparation is an important factor influencing crop density and early establishment. It largely depends on weather conditions, but partly it can be controlled by soil management system. Field experiments of different soil tillage methods were carried out at Experimental Station of Aleksandras Stulginskis University in 2009. Treatments involved: 1) direct drilling, 2) shallow ploughing (10 cm depth), and 3) deep ploughing (20 cm depth). In the experiment spring barley (Hordeum vulgare L.) variety ‘Simba’ was cultivated. The soil of experimental site – Calc(ar)i-Endohypogleyic Luvisol (Drainic). The aim of the research was to estimate the influence of soil management system on seedbed parameters and crop density. It was estimated, that the highest roughness of the soil surface (31.8 mm) was, when the soil was ploughed at 20 cm depth, but contrarily the seedbed roughness was the lowest (15.2 mm). Estimated direct drilling depth was 15.6 mm and in ploughed soil it was 51.7–57.4 mm. In ploughed soil at 20 cm depth the seeds were sown too deep – 88.4 % of them were below sowing depth. When direct drilling was used – too shallow – 57.8 % of seeds were above sowing depth. The highest accuracy was estimated in shallow ploughed soil – 43.8 % of the seeds were at sowing depth. Nevertheless in the dry weather conditions spring barley germinated faster when direct drilling was used, later on, experimental results showed, that spring barley crop density was significantly thinner (180 plants per m2) compared to deep or shallow ploughing, whereas depth of the ploughing did not influence thickness of crop stand: it was 431–445 plants per m2.
