Abstract :

In order to investigate the effect of vermicompost and vermiwash biological fertilizers on experimental growth of geranium plant, an experiment as a factorial form in a randomized complete block design with three replications in 2019 was conducted. The experimental factors were included vermicompost at non-using of 20 and 40% volumetric levels and at non-using of 100 and 200 ppm vermiwash. The results showed that using vermicompost was increased plant height, number of stems, internode length, number of flower stems, flower height, fresh and dry leaves weight, number of leaves per stem, leaf area index, root volume, potassium, nitrogen, phosphorus compared to control. The most plant height and flower height were obtained in 20% vermicompost treatment, and the highest number of shoots,fresh and dry leaves weight leaf area index in 40% vermicompost and the most potassium and phosphorus were obtained in 20 and 40% vermicompost treatment. According to the results, using vermiwash was increased plant height, internode length, number of flowering stems, fresh and dry leaves weight, flower height, shoot fresh and dry weight, number of leaves per stem, root volume, Nitrogen. The most plant height were obtained at 100 ppm vermiwash treatment and the highest flower height in 200 ppm vermiwash treatment. There is an additive effect, so that the highest internode length, shoot fresh weight, root dry weight, 40% vermicompost using with 200 ppm vermiwash, the most number of leaves per stem and fresh and dry leaf weight of 40% vermicompost using with 100 ppm vermiwash, the most root fresh weight of 20% vermicompost using with 200 ppm vermiwash, the most nitrogen concentration in 20% vermicompost treatment with 100 ppm vermiwash, the highest number of flowering shoots from different levels using of vermiwash with %40 vermicompost and non-using and using of 100 ppm with 20% vermicompost were obtained.
