| Abstract | ||
| The pots experiment carried out in the Saqlawiyah institute during the spring season 2008-2009 using sandy loam soil from Saddat Al-Falluja region. The soil was treated with black tea wastes (locally called "Bithil") with four treatments BT0 (control), TW1, TW2, TW3 with applications of 0%, 2%, 4%, and 6% respectively. Barley was planted for 65 days as a test crop. At the end of growth season, some of soil and plant properties had been measured. Generally, the treatments had a high significant effect in decreasing bulk density from 1.51 Mg.m-3 in TW0 to 1.27 Mg.m-3 in TW3 and a significant effect in increasing porosity from 41% to 50% for the TW0 and TW3 respectively. The treatments had also high significant effect in decreasing both the soil EC from 7.3 to 2.8 dS.m-1 for TW0 and TW3 respectively with negative correlation factor of – 0.98 and pH from 8.53 for TW0 to 7.59 for the treatment TW3. Tea wastes showed a high significant effect in increasing dry weight as average from 7.93 to 9.51 g.plant-1 for treatments TW0 and TW3 respectively with increasing ratio of 83%. The tillers number and the weight of 1000 seeds of the plant increased due to tea wastes application from 4 to 8 TPP (Tiller per Plant) and from 44.3g to 57.6 g for the treatments TW0 and TW3. The third treatment TW3 was the best in affecting soil properties and plant components. | ||
