Abstract In this study, it was aimed to determine the effect of different vermicompost applications on some yield components in bread wheat under Mardin conditions. The trial was established in 2017-18 in dry conditions, using two bread wheat varieties and four different vermicompost treatments in three repetitions according to the factorial experimental design in randomized blocks. According to the data obtained at the end of the experiment, the observed parameters were determined as respectively, the number of days of spiking (111.0 - 114.3 days), plant height (82.6 - 100.6 cm), plant spike length (7.2 - 10.3 cm), grain number per spike (29.8 - 55.9 pieces/spike), chlorophylls number (46.2 - 50.5 cci), vegetation temperature (21.8 - 22.6 °C), leaf area index (0.70 - 0.78 LAI), grain yield (4355.3 - 5360.7 kg ha-1 ) and crude protein (11.4 - 12.9%). As a result of the research, it has been determined that vermicompost applied in increasing amounts in all the properties studied except for vegetation temperature caused a significant increase. As a conclusion, vermicompost can be said to be a good organic fertilizer in cereal cultivation due to its environmentally friendly, soil-improving effect and sufficient and balanced plant nutrients in its structure.
