Comparison of the effects of different doses of vermicompost and compost applications on the nutrition of cress (Lepidium sativum L.) with plant analysis

This study was carried out in 2500 g pots according to the trial pattern of coincidence parcels under controlled greenhouse conditions, and two different organic fertilizers [vermicompost (VC) and cow manure (compost, CM)] were planted in 0% (control), 1%, 5%, 3%, 6% doses, mixed with the soil sample taken from Lüleburgaz district of Kırklareli province and the trial was completed after 2 months. The trial was carried out in a controlled manner in the greenhouse belonging to Ziya Organik Tarım İşletmeleri A.Ş. located in Lüleburgaz district in the period between January and April 2021. The amount of organic matter of the soil used in the experiment was found to be 5.01. The fertilizers used in the study were statistically evaluated among themselves and vermicompost (VC) in terms of Mg, Mn, Zn, Cu; compost (C) in terms of N and K; In terms of P and Fe, both fertilizers have equal values and Ca is below <1.50.When the doses were statistically evaluated among themselves, significantly higher values were obtained in terms of plant nutrients at the overall dose of VC 1.5%. A 6% dose of C fertilizer of N and K and a 1.5% dose of P and Fe in both fertilizers were recommended from an economic point of view where all applications were appropriate. Mg, Mn, Zn, Cu VC fertilizer was said to be effective at a 1.5% dose. While the ideal dose of Ca applications should be between 2.00-3.00%, the highest dose of VC fertilizer was found to be 1.5 doses with 0.765. It was found that the plant nutrient content of the applications was statistically significant (P≤0,01). When the results of the trial were examined, it was found that both organic fertilizers had a significant effect on the macro and micro plant nutrient content of the cress plant at different levels.
