Summary

Results of study on self-made nutrient solutions for green mustard and tomatoes in hydroponic cultivation

Results of study of 8 solutions: solution, imported from Taiwan gave the best results in terms of development of tomatoes. 4 of 7 self-made nutrient solutions showed good results in yield improvement of tomatoes. Using of these solutions for tomatoes produced higher yield than these solutions 1 improved from Taiwan. Based on yield increase we could rank the usefulness of these solutions as the order: modified Knop product > modified Taiwan product > FAO product > modified Knop solution (solution 7) was very low but it gave the highest yield of tomatoes.
