Integrated effects of rhizobial inoculant with vermin-compost (vc) on groundnut (Arachis hypogaea L.) in pot condition
Abstract
The study was conducted to evaluate the integrated effects of rhizobial inoculant and vermicompost on the growth, nodulation, and yield of groundnut (Arachis hypogaea L.) under pot conditions at the Soil Science Division, BINA, Mymensingh during 2024. The experiment comprised five treatments: T₁ (control: I₀ + VC₀), T₂ (N₆₀P₆₀K₇₅S₆₀), T₃ (I₁ + P₆₀K₇₅S₆₀), T₄ (VC₁₀ + P₆₀K₇₅S₆₀), and T₅ (I₁ + VC₁₀ + P₆₀K₇₅S₆₀), arranged in a randomized complete block design with three replications. Results revealed significant differences (p< 0.05) among treatments for growth, nodulation, and yield parameters. The combined application of rhizobial inoculant and vermicompost (T₅) produced the highest number of effective nodules per plant (96.67), nodule weight (0.60 g plant⁻¹), number of pods per plant (10.83), and yield (17.4 g pot⁻¹), representing a 91.84% increase over the uninoculated control. The enhanced performance of T₅ indicates a strong synergistic interaction between Rhizobium inoculation and vermicompost, resulting in improved nitrogen fixation, nutrient availability, and plant vigor. These findings demonstrate that integrating biofertilizers with organic amendments can effectively improve the productivity and sustainability of groundnut cultivation while reducing dependence on chemical fertilizers.
