Field trials were carried out on organic farming fields at the Research Institute of Agriculture of the Latvia University of Agriculture (LLU). The influence of pre-crop (red clover, winter rye for grain, bare fallow, bare fallow and green manure), use of stable manure (60 t haE-1 or without) and harrowing (without harrowing, before shooting, at the stage of tillering, before shooting, and at the stage of clustering) on the yield of spring barley 'Sencis' were tested during 2003-2004. Depending on the variants the grain yield in the field trial varied from 1.56 to 3.85 t haE-1. Data show that previous plants and stable manure influenced barley grain yields significantly. The highest yields in barley were obtained after red clover. Harrowing increased the yields of barley only after winter rye for green manure by using stable manure, but the time of harrowing had no influence on the yield of barley. The thousand grain weight was medium - 33.5-38.4 g, medium was also volume weight - 609.0-633.5 g lE-1. The content of crude protein was satisfactory to good - 96-117 g kgE-1.
