Maize is one of the most important cereal crops in India contributing significantly towards food and nutritional security. The experiment was carried out to study the effect of nitrogen levels and plant growth regulator (PGR) on plant dry weight, crop growth rate (CGR) and yield attributes in maize crop. The experiment was conducted during Rabi season of 2019-20 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.). The experiment was laid down in RBD having 12 treatments with three replicates. Experimental results found that the treatment 10 (120 kg Nitrogen + NAA 40 ppm) had higher plant height (181.66 cm), higher plant dry weight at 60 DAS (5.08g), 100 DAS (19.60 g) and at harvest (95.83g), Higher Crop Growth Rate at 60-80 DAS (0.12 g/m2/day), 80-100 DAS (0.61 g/m2/day) and At Harvest (1.08 g/m2/day) and in yield attributes i.e. maximum Number of cob/plant (2.30 cob/plant) Cob length (13.86 cm), Maximum 100 seed weight(31.50 g), Maximum Grain yield (5015.33 kg/ha) also in treatment 10 (120 kg Nitrogen + NAA 40 ppm) with maximum B:C ratio of 2.17 followed by treatment 12 (120 kg Nitrogen + Putrescine 50 ppm). Thus, it may be concluded that use of nitrogen @120 kg/ha with Naphthalene Acetic Acid (NAA@40ppm is beneficial during Rabi season in maize crop leading to better yield attributes and return from the crop.
