Title

AZOLLA AN ENVIRONMENTAL PROBLEM OR AN APPROPRIATE GROWTH MEDIUM OF ORNAMENTAL PLANTS?

Pages

  555-571

Abstract

 Climatic conditions of Guilan have been helped to expanding Azolla growth in wetland and ponds of this province. Regarding environmental problems of Azolla accumulation, a study was conducted to investigate impact of composted Azolla with nutrient solution on the growth of DRACAENA marginata in replacement of PEAT at ORNAMENTAL PLANTs and Flowers Research Station, Lahijan, Iran. The control treatment was a 2:1 ratio of PEAT: perlite (v/v) and PEAT was replaced by composted Azolla at zero, 25, 50, 75 and 100 percent v/v. The research was conducted as a factorial experiment based on a completely randomized design in three replicates with 90 plants. Substrate properties including bulk density, porosity, electrical conductivity, pH, C/N ratio and phosphorus, potassium, iron, zinc and manganese concentrations were measured. Plant growth indexes including leaf and stem dry weight, leaf and stem fresh weight, plant height, stem diameter and number of leaves were measured. The results showed that the highest growth was observed at 75 and 100 percent AZOLLA COMPOST with nutrient solution and the lowest growth obtained at control and 25 percent compost of Azolla. AZOLLA COMPOST without nutrient solution had a greater effect on plant growth as compared with control even with the consumption of nutrient solution.
