Abstract

Field experiment was conducted in sandy loam soil at CCS Haryana Agricultural University, Hisar, Haryana to assess the germination, attainment of phenophases and yields of late sown wheat under different agronomical management practices. The highest germination (m–2) of wheat was observed in dry seeding with overnight soaked seed with 25% higher seed rate on 15th December followed by irrigation. The attainment of heading, anthesis and physiological maturity took longer time in 15th December sown treatments as compared to 1st January sown treatments. The accumulated heat unit for particular phenophase is directly proportionate to duration of that phenophase, therefore, accumulated heat unit was observed higher with 15th December sown treatments as compared to 1st January sown treatments. The seed soaking and higher seed rate improved the thermal use efficiency over the dry seeding with normal seed rate. Similarly, soaked seed sowing also helped 2 days early germination. Among all the treatments, dry seeding of overnight soaked seed with 25% higher seed rate on 15th December followed by irrigation resulted in significantly higher grain (4.20 t/ha) and biological yields (10.36 t/ha).
