Effect of bacteria-mineral water produced from bio-reacted fowl dung on seed germination of wheat (Triticum aestivum) and rice (Oryza sativa L.)

Positive effects of Bacteria-mineral water (BMW) produced from bio-reacted manure on plant growth and crop seed germination has been observed in agriculture practices. The experiment was conducted to examine the effects of BMW produced from bio-reacted fowl dung on seed germination of rice (Oryza sativa L.) and wheat (Triticum aestivum). Seeds were soaked in BMW at concentrations of 100, 10, 1, 0.5, 0.25, 0.125, 0.025, and 0% (control) and then incubated at 25°C ± 1°C in a seed germinator for 7 days. All BMW treatments not only enhanced germination energy and final germination percentage of wheat and rice seeds, but also significantly improved (P < 0.05) seed vigor index (VI). Compared to control, treatment with 0.25% BMW had significant effects (P < 0.05) on final germination percentage and increased significantly seed germination percentage (7.34%) and germination energy (8.67%) of wheat seeds. There were strong correlations between germination energy and final germination percentage (P < 0.05), germination index (P < 0.05), VI (P < 0.05), water absorption rate (P < 0.01), and storage reserve transform rate (P < 0.01). While for rice seeds, 0.25% and 0.125% BMW treatments significantly improved (P < 0.05) final germination percentage by 8% separately, and germination energy enhanced 8.66% and 9.33% respectively. There were strong correlations between germination energy (and final germination percentage) and other parameters except for water adsorption rate and storage reserve loss rate. BMW consistently showed positive effects on crop seed germination. 0.25% BMW treatment may be the best concentration to stimulate wheat (Triticum aestivum) seeds germination, while 0.125-0.25% BMW would be the most suitable concentration range for rice (Oryza sativa L.) seeds.
