Short term experiment with different soil tillage systems in soybean (Glycine max L.) and spring barley (Hordeum vulgare L.) production was conducted at the experimental field near Našice on gleyic soil type and semi humid climate conditions. The tillage systems and implements used were: CT – mouldboard plough, disc harrow, seed-bed implement, RT 1 - chisel plough, disc harrow, seed-bed implement, RT 2 – shallow chisel, NT – no-till. Soybean production was economically efficient only with the substantial reduction or complete omission of tillage. While the production of spring barley has proven to be economically efficient at all variants of soil tillage, better economic results were achieved with the reduced tillage and no-till systems. The highest productivity regarding labour requirement per hectare and ton of grain yield was achieved with NT system in both winter barley and soybean production. Regarding the choice of tillage systems, assuming uniform level of yields, the advantage should be given to systems with lower level of tillage intensity, not only to reduce costs but also because of the possibility of simpler production organization due to less machine and labour requirement. |
