In: Annals of agricultural science 2010.v.55(2)Summary: In a field naturally infested with weeds and soilborne pathogen, field experiments were conducted in the vegetable farm at Faculty of Agriculture, Aln Shams University in clay soil, to study the effect of Seed-bed solarization of organic production on growth and yield of spinach plant. Well prepared and pre-irrigated seed-bed plots with and without organic manure were covered on 1" August with transparent polyethylene mulch of 50 ~M thick, for six weeks prior to spinach sowing in early October of 2006 and 2007, Solarization raised the average maximum soil surface temperature to 58.5°C wtth organic manure and 56°C without organic manure. SOlarization increased soil surface temperature by 4.5°C and 3.5°C degrees over the non-solarized soil In the first and second season, respectively. Soil solarization significantly reduced total fungal and bacterial count.
