Abstract: A field experiment was conducted at Thanthai Roever Institute of Agriculture and Rural Development, Perambalur, Tamil Nadu on black cotton soils during Kharif season of 2016 to study the Integrated Nitrogen Management on the growth and yield of Hybrid Maize (NK 6240). The experiments were laid out in randomized block design with ten treatments and three replications. The growth and yield components of hybrid maize viz, plant height (92.60, 160.92 and 210.87 cm at 30, 60 DAS and harvest), leaf area index (4.61 at 60 DAS), dry matter production (5080.01, 12352.23 and 17500.38 kg ha-1 at 30, 60 DAS and harvest), number of cobs per plant (1.40) and number of grains per cob (460.70), hundred grain weight (28.98 g) and yield (7450.70 kg ha-1 ) were favourably influenced by the application of 75% N through inorganics + 25% N through Poultry Manure + 100% P&K through inorganics (T4). It was followed by T6 (75% N through inorganics + 25% N through Goat Manure). The least growth and yield components and yield was noticed under the control treatment (T1).
