Effect of addition of some organic waste to soil on yield and some growth indices of greenhouse cucumber

The yield of plants are affected by different factors. If these factors be prepared for the plant equally and ideally, most of the output will be obtained. In order to detennine the combination effects of some organic wastes with soil on growing, yield and the quality of greenhouse cucumber, an examination was canied out in the greenhouse research center in Islamic azad university, Khorasgan branch with the use of six treatments include pure palmpeat, pure rice hull, soil+5%(weight) palm peat, soil+5%(weight) rice hull, soil+5%(weight) palm peat+5%(weight) rice hull and pure soil( Loam texture). The research was conducted in a completely randomized design with 7 replications. The amount of temperature and humiditywas constant for all treatments. Papadopoulos nutrient solution was applied through liTigation water. Some growth indexes including stem diameter, height of plant and plant biomass were measured at the end of growth period. The results showed that many of the growth parameterswere affected by the substrate significantly. Most of the yield in each plant(3 .67Kg), most of the plant height (3.28m), number of fmits in each plant (46.57) were obtained from pure palm peat.
