Investigating The Response of Some Vegetative, Qualitative and Quantitative Traits of Tomato Transplants and Whole Plants to The Substrate Types and Fertilizers
To investigate the response of transplant and whole plants of tomato (Solanum lycopersicum) to the type of substrate and fertilizer, a factorial experiment was conducted as a randomized block design in Minab city of Hormozgan province with three replications. The first factor included four types of substrates and the second factor included five fertilizers levels. The results of the greenhouse experiment showed that the substrate type and fertilizer had a significant effect on the transplant traits. The results showed that the maximum leaf number and root dry weight of transplants were obtained in the cocopeat + vermicompost substrate. In each substrate, fertilizers improved the transplant traits, and organic and biological fertilizers were more effective. Thus, the maximum transplant height was determined in the cocopeat + vermicompost with algae fertilizer, and the maximum fresh weight and root volume were measured in the same substrate but with phosphozite fertilizer. The results of the field study showed that the evaluated traits were affected by the substrate type and fertilizer, and the seedlings previously grown in the substrates that improved their traits, had better growth after transferring to the field. The results showed that the highest number and yield of fruit, total soluble solids, and ascorbic acid were obtained in the seedlings produced in cocopeat + vermicompost substrate and organic fertilizers.
