Abstract
Forage pea, which is used from its grains, green and dry grass, is an annual legume forage plant that is consumed by animals and is very rich in nutritional value. An ideal soil for plant growth should have physical and chemical characteristics such as proper drainage, adequate aeration, and available moisture. To meet these conditions, organic or inorganic substances are used separately or in mixtures as soil conditioners. In the study, root and stem development of forage pea inoculated with Panteo agglomerans and Pseudomonas putida was investigated in thirteen media consisting of 100% cocopeat, peat, tea waste, perlite and different ratios on a weight basis. Five plants were planted in each pot and harvested after fifty days. Root and stem dry weights, nitrogen contents, crude protein values and total bacterial count of plants dried at 65 °C were determined. It was determined that 100% cocopeat medium was more suitable for the investigated parameters in the forage pea whose root and stem development were examined in different environments. Panteo agglomerans strain was more effective than Pseudomanas putida strain on stem dry and wet weight, root and stem length and bacterial count, bacterial applications gave better values compared to the control. Key words: Cocopeat, Pseudomanas putida, Panteo agglomerans, Soil conditioner, Tea waste
