Abstract

An experiment was conducted during 1998 and 1999 at Pantnagar, to study effect of sowing time and irrigation on seed vigour and soil moisture and yield of sunflower (Helianthus annuus L.). Date of sowing and irrigation significantly influenced phenology, available soil moisture, seed moisture contents and seed vigour. However, irrigation did not affect germination (%) and shoot length significantly. Seed moisture content could also not affect by date of sowing , significantly. Dormancy effect just after harvest and storability effect after 4 months were also observed.
