Ivy Geranium (Pelargonium peltatum (L.) L’Hér.) Plant Growth and Flowering as Affected by Mineral or Biofertilizer with or without Compost Amendment

Sustainable agriculture aims to eliminate the excessive usage of chemical fertilizers and can be crucial for soil fertility. A factorial pot experiment in a randomized complete block design was carried out King Khaled International Airport Nursery, Riyadh, Saudi Arabia, during 2019/2020, evaluate role biofertilizer (i.e., Bio-Fert, nitrogen-fixing microorganisms; Biot-Phos, phosphorus-released microorganism; Bio-Potas, potassium-released microorganisms, either alone or combinations) slow-release compound fertilizer (Osmocote), with without compost, on Pelargonium peltatum plant growth, flowering, chlorophyll level, ion percentage. Soil amendment compost general significantly increased growth flowering attributes as well nitrogen (N), phosphorous (P), potassium (K) percentage over garden (without compost). All traits level were by treatments combinations. The supreme treatment triple interaction single double interactions untreated plants. Osmocote application increases levels, ions, vegetative relative Additionally, data also revealed that all between osmocote biofertilizers studied each control Accordingly, it is recommended add along mixture obtaining high
