A field investigation was carried out during two consecutive seasons of Kharif 2013-14 and 2014-15 at Students’ Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur to study the “growth and yield of hybrid maize (Zea mays L) under different plant geometry and fertility levels”. The investigation result on the pooled basis showed that the maximum plant population, plant height and number of leaves was recorded with the plant geometry 67 × 20 cm (75000 plants / ha), while maximum fresh and dry weight were recorded in plant geometry 67 cm × 25 cm (60000 plants/ha). In the case of fertility level RDF 100% and RDF 75% + Azosp + GM were recorded maximum plant population at initial and plant height at 15 DAS. The maximum plant population at harvest were recorded under the treatment RDF 75% + Azosp + GM and RDF 75% + PSB + GM. Treatment RDF 75% + PSB + GM was recorded maximum plant height at 30 DAS. The maximum plant height at 45 DAS and harvest were recorded with RDF 75% + Azosp + GM fertility level. The maximum number of leaves, fresh and dry weight was recorded with RDF 100%. The plant geometry 67 cm × 22.5 cm (66666) plants/ha) and fertility level RDF 75% + Azosp + GM recorded maximum grain yield of maize.
