| Abstract | ||||
| Under clay soil texture of plastichcuse conditions at Sakha Agric.Res. Station, the soil was treated with different microorganisms using in eight treatments. Cucumber was sown on 13 January, 2004 and 2005. Seedlings of 32 cays old viere transplanted into the soil of a plastichouse. The soil treatments were as follows:- (1 ) control (CL). (2) Topsin (TP) 2.5 gm I L. (3) and (4) Saccharomyces composted in chicken manure (3) (YES + CHI) and in cattle manure (4) (YES + CM). (5) and (6) Trichoderma harzianum, composted in chicken manure (5) (TRI +CHI) and in cattle manure (6) (TRI + CM). (7) and (8) Bacillus subtilis composted in chicken manure (7) (BAC + CHI) and in cattle manure (8) (BAC+CM). The present study aimed to investigate the effect of the previous treatments on growth characters and fresh yield of cucumber and its components as well as pathogenicity study i.e. percentage of Pre, post, and survival plant. Each plant treatment received 100mL of it's proposed materials three times a week and the total applications were six. Accordingly, <:! complete ranee mized block was used witl four replicates. The obtained results indicated that (TRI + CM) gave the highest plant length, the largest Iczf <ire,", the biggest fresh weight and number of leaves. At the same time, (TRI+CM) anc (GAC + CM) led to increase significantly the plant leaf area index. Bacterial, (SAC + CM) end (BAC+CHI) resulted in the higher number and total yield per plant. In ecclticn, significant increase of early yield was recorded by (BAC+CM), (BAC+CHI), (TRI+CM), (TRI+CHI) and (YES+CM) respectively compared with control. The effectiviness of treatments on controlling damping off diseases for the host cucumber plant was ranged from 80 to 100%. Bacillus subtilis (SAC) and Trichoderma herzienum (TRI) composted in cattle manure obtained the lower percent of disease incidence than the other treatments used including (control). | ||||
