摘要:A field experiment was conducted during the 2014-2015 at the research farm of School of ForestryandEnvironment, Sam Higginbottom Institute of Agriculture Technology and Sciences, Allahabad, to find out the influence of weather parameters on Lentil (Lens culinaris M.) under Allahabad condition in Randomized block design (factorial) replicated thrice. Induction of hydro priming was obtained by immersing the seeds in distilled water. The GDD accumulation was highest in D1 (1907.25 day °C) than other sowing dates. The minimum GDD was accumulated in D3 sowing (1633.15 day °C). The highest PTU was obtained by D1 (21899.10°day hrs). The hygrothermal unit-I was highest (168544.70°day percent) in the D1. HgTU-II, photo temperature, nycto temperature, inter diurnal temperature was also highest in D1.
