Effect of growing media on its physical and chemical properties on beet root yield under protected cultnation

A field experiment was conducted during 2008 to 2009 in naturally poly house. Selected chemical and physical characteristics off our types of growing medias comprising of coirpith, perlite, vermiailite and peat as separately and combination with vermicompost as 50% on volume basis ((v/v) were determined and their suitability as growing media was tested using beet root (nobol). Data on pH, EC, nutrient contents and various aspects of air-water relationships of the media, as well as yield of beet root were collected. The root yield per treatment was notsignificantly influenced by the treatments T₁, T₂, T₃ and T₄ but while root yield of beet root was found to be significantly influenced by treatments T₅, T₆, T₇ and T₈. Results indicated that certain chemical and physical pmperties of selected soilless media can be impmved through incorporation of vermicompost and its positive effect was clearly reflected in the yield of beet root
