This study aims to compare the effects of different laser wavelengths, exposure times, and low-power-intensity laser irradiation on maize seeds. Seeds were exposed to He–Ne (632.8 nm) red laser, Nd:YAG second-harmonic-generation (532 nm) green laser, and diode (410 nm) blue laser. Four different exposure times (45, 65, 85, and 105 s) with different intensity (2 and 4 mW/cm2), for each laser were tested. Phenology and yield components (plant height, leaf area, number of rows per ear, seed yield, harvest index, yield efficiency, and grain weight) were determined. The experiment was conducted in a randomized complete block design with three replications. Plant height was found comparatively high in blue laser light—211 cm at 85 s. Blue and green laser lights showed significant increases in the number of rows per ear to 39.1 at 85 s and 45 at 65 s, respectively, compared to the control of 36 rows/ear. The order of seed yield was blue (7003.4 kg/ha) > green (6667.8 kg/ha) > red (6568.01 t/ha) based on different exposure times of 85 s, 85 s, and 105 s, respectively, compared to the control of 6.9 kg/ha. The findings indicate the possibility of using blue laser light to manipulate the growth and yield of maize.

The biohydrogen production from food wastes by anaerobic fermentation of digested sludge is studied. It is found by gas chromatography analysis that the volumetric ratios of H2 to CO2 in the biogases derived from rice, potato, lean meat and fat are respectively 0.77, 0.82, 0.93 and 0.82. The yield of methane is quite little, because the methane-producing activity is restrained and the hydrogen-producing activity is simultaneously kept when the digested sludge is preheated in the boiling water. Ethanol (0.43%) is the highest volatile fatty acid in the fermentation solution derived from lean meat, implying that it belongs to ethanol-type fermentation. The butyric acid concentrations are the highest (respectively 0.96%, 0.44% and 0.34%) in the fermentation solutions derived from rice, potato and fat, which implies that they all belong to butyric acid-type fermentation.
