In this study, it was carried out in order to determine the amount of plant nutrients that can be obtained from the wastes of tomato plants grown with soilless agriculture technique in the greenhouse and to make suggestions for evaluation possibilities. For this purpose, cocopeat and plant samples were taken from the soilless greenhouse where tomatoes were grown at the end of production. The stem, leaf, fruit and root of the collected cocopeat and plant samples were separated and N, P, K, analyzes were made in these separated samples. According to the results obtained, the amount of N that can be added to the soil with the cocopeat wastes is determined as 10.58 kg, the amount of P 0.09 kg and the amount of K 0.52 kg for one decare area. The total N amount that can be gained from the roots, stems, leaves and fruits of the waste tomato plant per decare area was determined as 6.65-11.97 kg, P content 1.22-2.52 kg and K amount between 5.10-18.21 kg. Considering the distribution of the amount of NPK that can be added to the soil according to the plant parts. On average, 4.18 kg in root, 2.50 kg in stem, ...
