Abstract

The effect of different agricultural and industrial residues (tomato, potato, barley, sugar–cane, sawdust and soil) mixed with cow manure at four levels of 25, 50, 75 and 100 percent was studied. The growth and REPRODUCTION rates, biomass production and average daily gain (ADG) of Eisenia fetida on a variety of organic wastes were estimated. A 6x4 factorial experiment and completely randomized design with a control treatment, three replications was used. The suitable cultures were determined using principal component analysis (PCA). There was a highly significant (p<0.0001) in the growth and REPRODUCTION rates, biomass production and ADG between AGRICULTURAL RESIDUES groups. The highest GROWTH RATE and maximum weight of worm was attained in the mixing of sawdust at % 25 levels (69.48±13.20 final gr/initial gr). The maximum biomass of worm was obtained in substrates of sawdust and cow manure 372.84 and 338.14 gr respectively, whereas the treatment of potato and barley had the minimums biomass (134.94 and 45.08 gr respectively).The highest REPRODUCTION rate and the number of worm was obtained in the tomato mixture at %75 level (74.00±8.75 final nu./initial nu.). The lowest growth and REPRODUCTION rates was in the barely residues (6.64±1.09 and 3.85±0.89 respectively), whereas the maximum of ADG was in this treatment (25.63 mg/w/d), on the contrary the large population density of EARTHWORMS in the tomato substrates resulted in reduction of ADG (5.52 mg/w/d). In general, the results of this experiment indicated that tomato, sawdust, sugar–cane, cow manure and soil mixtures produced the best environment for growth and REPRODUCTION of EARTHWORMS.
