RICE STRAW RECYCLING FOR DEVELOPING THE HYDROPONICS SPROUTED BARLEY PRODUCTION AND CONSERVING THE ENVIRONMENT

Open-field burning of the rice straw is clearly practiced and considered a significant source of air pollutants. Increasing the quantity and conserving the quality of the hydroponics sprouted barley are considered critical issue for feeding the large animals and executing food security. Therefore, the main objective of this research is to deter mine the best method for recycling of the rice straw as “a bio-media” and increasing the quantity and conserving the quality of the hydroponics sprouted barley. Randomize complete block design experiment was executed through (27) treatments. Three classes of rice straw m rough media (less than 7.5cm), medium media (less than 5cm), and fine media (less than 2.5cm); three ratios between rice straw weigh to dry grains weight 25, 50, and 75 (%); and three periods of growth life durations “8, 10, and 12 days” were applied. Statistical analysis processes of the results revealed that using medium media of rice straw (less than 5cm), with ratio of 50%, and periods of 10 days is considered the beast treatment.
