Abstract:
The field investigation entitled “Effect of Inorganic Fertilizers and Biofertilizers on Profitability and Productivity of Soybean [Glycine max (L.) Merrill]” during kharif, 2022 was conducted at instructional farm, College of Agriculture, Ummedganj-Kota. An experiment was laid out with Factorial Randomized Block Design with twelve treatment combinations with three replications, which includes inorganic fertilizers [50% RDF (10:20:20), 75% RDF (15:30:30) and 100% RDF (20:40:40) kg/ha] and biofertilizers (Rhizobium @ 600 g/ha, NPK Consortia @1250 ml/ha and Rhizobium @ 600 g/ha + NPK Consortia @1250 ml/ha). Results revealed that application of higher levels of inorganic fertilizers (100% RDF 20:40:40 kg NPK per ha) significantly improved the plant height (56.11 cm), chlorophyll content (2.87 mg/g), leaf area index (5.11), number of nodules/plant (53.04), fresh weight of nodules (172.76 mg/plant) and dry weight of nodules (68.18 mg/plant) of soybean than rest of treatments. Also, seed inoculated with Rhizobium @ 600 g/ha + NPK Consortia @1250 ml/ha recorded significantly higher plant height (53.16), chlorophyll content (2.79mg/g), leaf area index (4.42), number of nodules/plant (50.28), fresh weight of nodules (170.75 mg/plant) and dry weight of nodules (62.78 mg/plant) of soybean than individual inoculation of Rhizobium @ 600 g/ha and NPK Consortia @1250 ml/ha.
