A field experiment was conducted at Kanpur during Kharif seasons of 2005 and 2006, to find out the effect of hybrid rice 'PHB 71' to 3 dates of planting (15 July, 30 July and 14 August), 4 plant geometry (15 × 15cm, 20 × 15cm, 25 × 15cm and 30 × 15 cm) and 2 seedling rates (1  and 2 seedlings hill^-1). Hybrid rice planted on 15 July recorded significantly more grain yield (62.82 q ha^-1), which declined by 7.6 and 20.6% due to 15 and 30 days delay in planting, respectively. Planting the crop with a closer plant geometry of 15 × 15 cm produced significantly highest grain yield (59.18 q ha^-1) than wider plant geometry of 20 × 15 cm, 25 × 15 cm and 30 × 15 cm. Planting of 2 seedlings hill^-1 was beneficial with yield advantage of 8.2% over 1 seedling hill^-1.
