Glyphosate applied for weed control before sowing.conventional tillage (25 cm depth)
Application method: mouldboard ploughMouldboard plow to 25 cm depth followed by two passes of a cultivator to 15 cm depth, both in September–October- nitrogen fertilizer exposure Nitrogen applications were split with one-third applied before seeding as ammonium sulphate (21% N) and the remainder at the beginning of tillering, in February, as ammonium nitrate (33.5% N).
