Abstract: A field experiment was conducted during rabi season of 2016 at Jorapura Farm of Livestock Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the “Effect of integrated nutrient management on growth and yield of rabi forage maize (Zea mays L.)." Ten treatment combinations comprising of two factors viz., farm yard manure levels (M1: 10 t/ha, M2: 15 t/ha) and fertilizers (F1): RDF, (F2): Azotobacter + PSB, (F3): 50 % RDF + Azotobacter + PSB, (F4): 75 % RDF + Azotobacter + PSB and (F5): 100 % RDF + Azotobacter + PSB was laid out in randomised block design (factorial concept) with four replications. The results revealed that 15 t FYM/ha performed better by recording 5.67 and 5 per cent higher green forage (503 q/ha) and dry fodder (105 q/ha) yield, respectively over 10 t FYM/ha. Combined application of 100 % RDF + Azotobacter + PSB performed better by recording 58.23 and 52.63 per cent higher green forage (557 q/ha) and dry fodder (116 q/ha) yield over other treatments. The results revealed that application of 15 t FYM/ha performed better by recording higher plant height (165.9 cm), number of leaves per plant (12.6), stem girth of 3rd internode (7.96 cm), leaf area per plant (3624 cm2), leaf: stem ratio (0.34) and length of internodes (12.1 cm) respectively over application of 10 t FYM/ha. Combined application of 100 % RDF + Azotobacter + PSB recorded higher values of plant height (175.8 cm), number of leaves per plant (13.5), stem girth of 3rd internode (9.28 cm), leaf area per plant (4000 cm2), leaf: stem ratio (0.37) and length of internodes (12.7 cm) over other combinations. It is concluded that the application of 15 tonnes farm yard manure per hectare along with 100 % RDF + Azotobacter + PSB found superior followed by the application of 15 tonnes farm yard manure per hectare along with 75 % RDF + Azotobacter + PSB.
