Evaluate the effect of seed coating with biological and chemical substances, as biofertilizer on seed germination of cumin (Cuminum cyminum L.)

In order to evaluate the effect of seed coating with biological and chemical substances, as biofertilizer on seed germination of cumin (Cuminum cyminum L.), this research was conducted in two separate sections as a factorial experiment in the form of completely randomized design (CRD) with four replications in lab and research greenhouse of Kashmar University Jihad Institute in Kashmar in 2018-2019. In the greenhouse, the first factor was coated with chemicals (Lamadur fungicides, Carboxyl Tirah fungicides, Topsin M. fungicides, Gaoucho insecticides, Cruz insecticides) and coated with biological materials (Trichofarm fungus, Biofarm bacterium and Probio 96 bacteria), and the second factor is the use of sterilized soil and soil containing fusarium and in the laboratory, the first factor include coating with chemicals (Similar to the greenhouse) and Also covered with biological materials (Similar to the greenhouse), and the second factor was the application of three temperatures of 5, 10 and 25 ° C. The results of the laboratory showed that the effect of coating, different temperatures and interaction effect of coating with different materials and temperatures on, seedling length, seed germination percentage, germination rate and SV II index at the level of 1% were significant. The results showed that the highest seedling length (7.5 cm) was related to untreated seed treatment at 10 ° C and the lowest (1.3 cm) in cleaning up seed+ Carboxyl Tirah fungicides + Gao Chu insecticide. The results showed that the highest germination percentage (0.245%) was related to untreated seed treatment at 5 ° C. Generally the results showed that in the laboratory control treatment at 10 ° C increase germination percentage and vigure of length seedling in compared to other treatments but in the greenhouse, the use of growth stimulating bacteria (PGPR) was recommended.
