Abstract:
Maize (Zea mays L.) has been recently established as an energy-rich and technically advantageous substrate for the production of electricity from renewable sources of energy in biogas plants. Maize as a substrate for biogas production only has been started to investigate in Latvian conditions. Researchers have mentioned that key factors for a maximum biogas yield from maize are selected hybrid (genotype), time of harvesting, type of conservation and pretreatment of the biomass. Also the nutrient composition of the energy crop is important.. Field trial was carried out in Research and Study farm “Vecauce” of the Latvia University of Agriculture (LLU) in 2008 and 2009. Ten (in 2008) till eleven (2009) maize hybrids with different maturity rating (FAO 180 – 340) were harvested at three different times. Results showed that harvest time effect on maize yield was substantial (p<0.05) in both years. The highest organic dry matter yield was obtained harvesting maize on October 3 in 2008 and on October 6 in 2009. The C/N ration rose from 30 at first harvest in 2009 to 38 at the last harvest date in 2009. The paper aimed to evaluate impact of hybrid, harvest time and agro-meteorological condition on maize biomass production for biogas.
