Abstract:   (2225 Views)
The present study was conducted at Isfahan University of Technology greenhouses on tomato (Solanum lycopersicum cv. Chef) as a factorial experiment in completely randomized design with six treatments and four replications including: complete fertilizer 20:20:20, Johnson's solution, Johnson's solution with wood vinegar, Johnson's micronutrients and macronutrients with wood vinegar, macronutrients nutrients with wood vinegar, and micronutrients with wood-vinegar, in two soilless (Cocopeat-Perlite 1 to 1 ratio) and soil. Results showed that stomatal resistance and transpiration in Johnson's solution increased the highest amount and photosynthesis of Johnson's macro and micronutrient elements along with wood vinegar. Greenness index was the highest in Johnson's solution with wood vinegar and Johnson's macro and micro nutrient elements with wood vinegar. Plant height in whole manure, Johnson's nutrient solution, Johnson's nutrient solution with wood vinegar and micronutrient elements Johnson did not change significantly in cocopit medium and in macronutrient elements with wood-based vinegar and micronutrient elements Wood vinegar decreased and was lower in all treatments in soil. Root volume and root weight in complete fertilizer treatment, Johnson's nutrient solution with wood vinegar, Johnson's nutrient and low nutrient content with wood vinegar, and nutrient intake with wood vinegar in cocopeat medium and root dry weight in complete fertilizer treatment Johnson's  with wood vinegar, macro and micronutrients consumption of Johnson's wood vinegar, and high consumption of wood vinegar with wood vinegar were the highest in the cocopeat medium. The highest yield was obtained in the treatment of Johnson's nutrient solution, Johnson's solution with wood vinegar, and nutrient intake with wood vinegar in the soilles culture and the lowest in all soil medium.
