Abstract

Greenhouse tomato production is in the first place in Turkey, 34% of total tomato production (3.614.472 tonnes) is under greenhouse conditions. The increase in yield in Turkey is due to the spread of undergrowth cultivation besides the use of qualified varieties and seeds. Synthetic fertilizers can‘t be used to obtain economic efficiency in underground organic tomato growing Therefore, the application of alternative fertilizers (barn stubble, green manure, organic fertilizer, vermicompost etc.) needs to be improved. For this purpose, effect of the eight different fertilizer combination including organic and worm liquid fertilizer, humic acid and mycorrhizae applications on tomato plant and fruit yield were investigated in the study. Negative check without any fertilizer application growing and a positive check; a synthetic liquid fertilizer application was included. Experiment was set up according to completely randomised block design with 3 replications under greenhouse conditions. Tomato fruit length, diameter and weight was determined as fruit yield and fresh and dry weight as plant yield. There was not any statistical difference among fertilizer applications for fruit and plant yield. However, the highest tomato fruit yield was obtained in the treatments of organic (7.17 kg/ plot) and worm fertilizers (4,80 kg/ plot) in combination with mycorrhizae. The results were similar for fruit diameter and length. Plant fresh and dry weight was between 2.01 to 5.92 and 0.368 to 1.153 kg, respectively. The highest plant weight was belong to mycorrhizae and organic fertilizer application.
