Effect of mineral fertilizers and inoculation with nitrogen-fixing bacteria on yield and biomass of Cicer arietinum L.
Jonita Perfanova, Hristo Valchovski, Gergana Kuncheva, Lev Tribis
Abstract: The study evaluates the grain yield and green biomass of chickpea (Cicer arietinum L.) at four levels of nitrogen and phosphorus fertilizers, with sole inoculation with strain Bradyrhizobium sp. (cicer) 3352 and combined effect. The plants were grown until the full maturity of grain in pot experiment on two soil types Alluvial meadow soil (Eutric Fluvisol) and Smolnitsa (Pellic Vertisols). Both inoculation with strain Bradyrhizobium sp. (cicer) 3352 and mineral fertilizers have strong positive effect of chickpea production and biomass. As a result of these researches, the optimal norm for mineral nutrition of chickpea (N70P160 mg/kg) was determined.
