- Abstract
In this study a total of 183 soil samples, 5kg each, were collected from the University of Tripoli Agriculture Experiment Station. Triplicates of 26 treatment combinations consist of air dried seaweed (SW), partially decomposed municipal waste (MW) and sewage sludge (SS), each grounded to pass 0.5 cm sieve were prepared to get mixed application rate of 20 t/ha. Other triplicates of 35 treatment combinations were prepared similarly to get mixed rate of 40 t/ha. One hundred kg/ha of 12-24-12 mixed fertilizer was added to each treatment. All treatments were incubated in a controlled moisture (50% of FC) and temperature (25 ±2 °C) greenhouse compartment for four months. At the end of this period some chemical and microbiological analyses were conducted. Tomato (Rio Grande) seedlings were planted and let grow for four months during which care was taken of keeping moisture and temperature as indicated earlier whilst number of leaves and plant heights were recorded periodically each month. At the end of the experiment the above aerial portions of the plants were separated from the roots and put in separate punched paper envelopes and dried at 60 °C for two days. The dried weights were recorded. The results indicated that there was no tangible difference between the 20t/ha and the 40t/ha combination treatments. The combined dry weight (roots + aerial portions) ranged from 7.65- 19.73 g/pot with an average of 11.94 g/pot in the 20 t/ha experiment. With regard to the 40 t/ha experiment, the combined dry weight ranged from 1.67-19.83 g/pot with an average of 11.10 g/pot. In both experiments, the dry weights in seven different combination treatments were higher than the control treatment (soil alone).
