Abstract The effects of compost addition and simulated solarisation of soil on the survival of Ralstonia solanacearum biovar 2 strain 1609, as well as on the structure of indigenous soil bacterial communities, were analysed. In addition, effects on the invasion of susceptible test plants by strain 1609 were assessed. In untreated soil in microcosms and the field, strain 1609 showed slow progres...

although host plant resistance is the healthiest, most reliable and cheapest way of pest control, to achieve a successful integrated pest management, pest-resistant plant varieties should be compatibity with the biological control agents. throughout the present study, the performance of the predatory mite, phytoseiulus persimilis، on four common bean cultivars (naz, khomein, akhtar and g11867) ...

the effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). the study was performed in a randomized complete block design with 3 replicates. results indicated that application of organic substances enha...

BACKGROUND The aim of this study was to determine the potential of produced compost from the sludge of wastewater treatment plant using earthworms and compare it with the vermicompost produced from household solid waste. METHODS In the current study, three treatments with the same conditions in terms of organic wastes type were prepared to produce vermicompost from household solid waste and s...

In this study, the use of composted sewage sludge (CSS) as a binary component with peat (P) in growth media for a horticultural crop, broccoli (Brassica oleracea var. Botryti cv. Marathon), was evaluated. Four treatments were established, based on the addition of increasing quantities of composted sewage sludge to peat (0%, 15%, 30% and 50%, v/v). Physical, physico-chemical and chemical analyse...

AIMS To determine the effects of heat and composting treatments on the viability of the plant pathogen Phytophthora ramorum grown on both artificial and various natural substrates. METHODS AND RESULTS Phytophthora ramorum was grown on V8 agar, inoculated on bay laurel leaves (Umbellularia californica) and on woody tissues of coast live oak (Quercus agrifolia). Effects on growth, viability and...

This research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. Effect of peanut shells composts on the growth of Viola tricolor and marigold was investigated during seven months. Peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. Plant g...

in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...
