| Summary: | To evaluate seed vigor of marigold affected as organic, biological, nano and chemical fertilizers on mother plant, a study was conducted in Research Center and Education of Agricultural and Natural Resources of Khorasan Razavi province. Plants were under the impact of 10 fertilizer treatments contains Compost (15 ton/ha), Vermicompost (5 ton/ha), cow manure (15 ton/ha), Compost with Pseudomonas putida, Vermi compost with Pseudomonas putida, Nanobiologic fertilizer (1.5 L/ha), Nano chalate ZFM (2 kg/1000 L), Nano composit Bioorganic (200 kg/ha), Chemical fertilizer (150N,50P,50K) and control. The experiment was conducted in a completely randomized design with 10 treatment with three replications. . Then traits such as percentage and speed of germination, mean germination time, seedling length, seed vigor index and seedling dry weight were measured. The results showed that fertilizer treatments had significant effects on germination percentage, germination rate, mean germination time, seedling length and vigor index of Calendula officinalis seeds but had not on seedling dry weight. The highest seed germination was found in compost treatment that was 94% (24.5% increment) and the lowest was seen in control treatment (76%). The highest germination rate was seen in compost treatment (6.05) and the lowest was in control (2.54). Application of compost in comparison to control showed 46.06% reduction in mean germination time. Also using compost had the greatest germination rate in compared to control (more than 138%). Overall compost treatment showed the best performance on the seed and seedling traits of marigold. |
