Effect of integrated nutrient management on growth, yield and quality of groundnut (Arachis hypogaea L.) under north Gujarat condition

A field experiment titled Integrated nutrient management on growth, yield, and quality of groundnut (Arachis hypogaea L.) under North Gujarat condition was conducted at the Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Banaskantha, Gujarat in the kharif seasons of 2022 and 2023. The experiment was laid out in a randomized block design with five treatments and four replications. The pooled results indicated that application of 75% RDF + Vermicompost 2 t ha-1 to groundnut crop recorded significantly higher growth parameters, yield attributes and yield viz., plant height at harvest (45.42 cm), number of pods per plant (18.15), pod weight per plant (13.53), pod (2343 kg ha-1) and haulm (3802 kg ha-1) yield as well as protein content (22.20%) in kernel of groundnut. However, application of 50% RDF + Vermicompost 2 t ha-1 + Rhizobium + PSB recorded significantly higher number of root nodules per plant (66.70), fresh (256.8 mg) and dry (95.73 mg) weight of root nodule per plant at flowering stage of groundnut crop.
