sufficient for growing tomato plants. The obtained results indicated that the nutrients consumption
increased with increasing the
flow rate. The root and shoot length increased with increasing effluent
flow
rate, when the effluent
flow rate increased from 4.0 to 6.0 L h1, the length of root and shoot significantly
increased from 50.33 to 55.33 and 149.33 to 191.33 cm, respectively, at the end of growing period. The
fresh and dry mass of shoot significantly increased from 998.01 to 1372.10 and 83.71 to 275.09 g plant1,
respectively, with increasing
flow rate from 4.0 to 6.0 L h1. The fresh and dry mass of root significantly
increased from 388.07 to 423.91 and 30.37 to 38.98 g plant1, respectively, with increasing
flow rate from
4.0 to 6.0 L h1. The fruit yield significantly increased from 1.06 to 1.37 kg plant1 with increasing
flow
rate from 4.0 to 6.0 L h1. The fruit mass and number of fruits increased from 75.07 to 81.32 g and 14.12 to
16.85 with increasing
flow rate from 4.0 to 6.0 L h1. The water use efficiency increased from 5.54 to
7.16 kg m3 with increasing
flow rate from 4.0 to 6.0 L h1. Using the effluent
fish farm could save
fertilizers which equivalents 0.13 LE kg1 fruits (130 LE t1 fruits). Besides it is considered as an organic
product which is safe for the human health. |
