Performance of N, P, and K Plant Uptake, as Effected by Application Both Compost Tea, Vermicompost Tea, and Rhizobia for Faba Bean Plant

Two field experiments were conducted in clay soil at own farm, Monufia governorate during the two successive seasons of 2020/2021 and 2021/2022 to study the effect of using some organic components as organic fertilizers and or growth, promoting substances on growth, yield and yield components of faba bean plants. Inoculated faba bean with rhizobial inoculation were treated with compost tea or vermicompost tea at two rates (5 and 10 L.fed-1) in combination with 1/3 N-fertilizer from the recommend dose. Vegetative growth, yield and yield components parameters, i.e., plant height, number of branches, plant dry weight, nodules dry weight, number of nodule, N, P, and K uptake (%) and number, weight of pods as well as seed yield and protein contents were also, determined. The obtained results indicated that application of both compost tea and vermicompost tea rerates up to 10 L, fed-1 had a positive effects on all tested parameters and caused significant increases when compared to untreated treatment. Using vermicompost tea at rate of 10 L. fed-1 with inoculated faba bean plant in combination with 1/3 N fertilizer dose is the best treatment for achieving better crop growth and yield of faba bean plants with reduced N-fertilizer uses as well as environment pollution.
