| Abstract | ||||
| The effect of sterilized or non-sterilized organic animal manures Le. chicken, horse, pigeon, mixed with SefTBtia marcescens in comparison with Oxamyl in controlling Meloidogyne incognita infecting Balady peach plant cv. Meet-Ghamr under greenhouse conditions showed that the unsterilized chicken manure and pigeon-dung accomplished the highest percentage of nematode reduction when applied either singly or integrated with Oxamyl or S. marcescens with values of 99.70, 98.80 or 98.78 and 99.68 or 98.57 and 97.60%, respectively. Moreover, the sterilized horse manure or pigeon-dung that applied either singly or mixed with Oxamyl or S. marcescens also achieved the highest percentage of nematode reduction with values of 99.5,72.9 or 97.60,99.67 or 98.n, 97.9%, respectively. However, the un sterilized horse manure as well as the sterilized chicken manure in a single application gave the least values of nematode reduction with values of 72.9 and 44.90%, respectively. In general, the unsterilized organic manures gave better results than the sterilized manures tested in improving plant growth response and suppressing nematode population whether in soil or root. A dramatic reduction in total counts of bacteria, fungi and actinomycetes was noticed in non-sterilized animal manures at 90 days after nematode inoculation. Mites identified from animal manures were related to Mesostigmata, Prostigmata and Cryptostigmata groups.The sterilized organic manures showed Significant increase in N, P and K, concentrations in dry shoot of peach plant exceeding those of nematode alone. The total chlorophyll was Significantly increased by the sterilized pigeon-dung alone or mixed with Oxamyl or by the unsterilized horse manure integrated with S. marcescens. | ||||
