abstract
An experiment was conducted on "Effect of zinc solubilizing fungi on growth, yield attributes and quality of groundnut" at Dr. BSKKV, Dapoli, Dist. Ratnagiri, Maharashtra, during 2022-23. The pot culture experiment was framed in completely randomized design (CRD) with 9 treatments and 3 replications. Regarding the growth attributes study, significantly highest plant height (23.26 cm), plant spread (32.42 cm), and number of nodules per plant (103.61), were observed by the application of 100% RDF + ZnSF at 2.5 L ha^-1 (T₅) followed treatments T₇, T₈, and T₃ which were found be at par with T₅. Furthermore, in the case of yield attributes, the application of treatment 100% RDF + ZnSF at 2.5 L ha^-1 (T₅) showed significantly higher dry pod yield (33.24 q ha^-1), kernel yield (23.97 q ha^-1), dry haulm yield (44.84 q ha^-1), shelling percentage (72.12%), number of mature pods, weight of mature pods per plant, weight of dry pods per plant, and weight of haulms per plant, and treatments T₃, T₇, and T₈ were found at par with T₅. Significantly higher oil content (50.12%) and protein content (24.88%) in groundnut were recorded by 100% RDF + ZnSF-2 at 2.5 L ha^-1 (T₅) and treatments T₃, T₇, and T₈ were found to be at par with T₅. The application of 100% RDF along with zinc solubilizers at 2.5 L ha-1 (ZnSF2-Aspergillus terreus) demonstrated significant superiority in the growth, yield attributes, yields, and quality of groundnut compared to other applications. This proved to be useful for adaptations in farmers' fields.
