Effects of some organic materials and inorganic fertilizers on nutrient contents of fenigreek (trigonella foenum graecum)

In this study determination of effects of tea waste (TW), spent mashroom compost (SMC) and inorganic fertilizers (IF) on nutrient contents of fenigreek (Trigonella Foenum Graecum) was aimed. The experiment was carried out according to factorial experiment and with three replication in 54 pots. Tea waste (0, 2.5, 5.0%) and spent mashroom compost (0, 2.5, 5.0%) were applied at three different doses of ammonium sulphate ( 0, 125, 250 mg N kg-1 ) Triple süper phosphate (0, 50, 100 mg P2O5 kg-1) and potassium sulphate ( 0, 75, 150 mg K2O kg-1) were used. Effects of organic material type, TW, SMC, IF doses and their interactions on N, P, Fe and Zn contents were found generally significant statistically. The highest N (5.43%), Fe (613 mg kg-1) and Zn (95 mg kg-1) means were found in SMC 0 IF 0 and SMC 0 IF 1 applications respectively. The highest P means were obtained as 0.43% in SMC 2 IF 2 applications. Generally, the means of nutrients obtained in SMC applications were found as higher than those obtained in the TW applications. Inorganic fertilizers applications increased N, P and Mn contens of plant
