Yield and nutritional value of maize for silage in dependance on type, rate and application of organic manures were investigated in a field semi-operational experiment established near the biogas station in the location of Kolíňany in the years 2004 and 2005. The trial results confirmed a statistically high significant effect of weather conditions on the maize aboveground phytomass yield. Under the infavourable weather conditions of the year 2004 a lower yield (28.01 t.ha-1) was achieved in comparison with the year 2005 (48.33 t.ha-1). When 50 t.ha-1 of biosludge was applied in autumn, the highest yield as well as the highest energy value of aboveground maize phytomass expressed in terms of net energy of lactation (NEL = 6.45 MJ.kg-1 DM) and net energy of fattening (NEF = 6.47 MJ.kg-1 DM) were achieved. Spring application of biosludge decreased the content of dry matter in maize by 20.7 %, and increased the content of crude protein by 13.7 %, crude fibre by 5.5 % and ash by 26.3 % compared to the values achieved at autumn biosludge application. The value of protein truly digested in the small intestine was the highest in treatment fertilized with farm - yard manure with the rate of 40 t. ha-1 (PDIN = 52.33 g.kg-1 DM, PDIE = 77.37 g.kg-1 DM). |
