The present investigation was conducted for two consecutive years with the objective to know various crop geometries and nutrient management approaches on soil chemical properties at Agricultural college farm, Bapatla. The experimental design was split plot with three replications. The present study comprised of three crop geometries with different age of seedlings (30x10 cm with 30 days old seedlings, 30x30 cm with 15 days old seedlings and 45x45 cm with 15 days old seedlings) and seven nutrient management practices (S0: absolute control, S1: FYM @ 10 tonnes ha-1 + application of dravajeevamrutham, S2: FYM @ 10 tonnes ha-1 + application of dravajeevamrutham along with wooden log treatment, S3: FYM @ 10 tonnes ha-1 + 100% RDF, S4: FYM @ 10 tonnes ha-1 + 100% RDF along with wooden log treatment, S5: FYM @ 10 tonnes ha-1 + 125% RDF, S6: FYM @ 10 tonnes ha-1 + 125% RDF along with wooden log treatment in subplots were given to kharif finger millet. integrated application of FYM @ 10 tonnes ha-1 + 125% RDF along with wooden log treatment (S6) resulted in higher organic carbon and nutrient status of the soil and reduced C:N ratio of the soil significantly though other soil properties were non significant due to various crop geometries and nutrient management treatments.
