Effects of organic materials and inorganic fertilizers on plant growth and nutrient contents of fenugreek (Trigonella foenum graecum)

In this study determination of effects of organic materials and inorganic fertilizers on plant growth and nutrient contents of fenugreek 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 differences organic materials on plant length, plant fresh weight, plant dry weight, root length and root fresh weight were found significant ( P<0.01 ) statistically Effects of tea waste doses on plant fresh weight, plant dry weight, root dry weight (P<0.05) were determined as significant statistically. Effects of spent mashroom compost doses and inorganic fertilizers doses on plant length, plant fresh weight, plant dry weight, root fresh weight and root length were determined as significant (P< 0.01) statistically. The highest plant length (32.94 cm), plant fresh weight (2.95 g), plant dry weight (0.33 g) means were obtained in TW2 applications. Effects of organic material type, TW, SMC, IF doses and their interactions on N, P, Fe and Zn contents were found generally significant statistically. In this study it was determined TW and SMC applications had generally positive effects on plant growth.
