P content was affected by the plant clone and the higher amount was belonged to Tabriz. The freash and dry weight plants, total flower number and fruit number affected by the individual effects of organic fertilizer and interactions of year × plant clone. Plant weight was influenced by organic fertilizer × marmarin and SA spray. The yield was impacted by the interactions of year × clone, year ×fertilizer, clone × fertilizer and the individual effects of organic fertilizer. Soil based organic fertilizer with foliar used marmarin and the organic fertilizer × SA increased chlorophyll a and b content. Chlorophyll a content was affected by the year as well as the second year had the more data. Silisium content was responsive to the sole effects of organic fertilizer interaction of clone × organic fertilizer.
