Effect of different levels of nitrogen and leaf cutting on growth, leaf and seed yield of coriander

摘要

An experiment was conducted to study the effect of nitrogen (0, 20, 40 and 60 kg N/ha) and leaf cuttings (no cutting, one cutting at 30 days after sowing and two cuttings at 30 and 50 days after sowing) on coriander. Plant height, different yield attributing characters, green leaf yield and seed yield were increased with the increase in nitrogen level. One cutting at 30 days did not affect the later vegetative and reproductive growth. Maximum seed yield was recorded with 60 kg N/ha without leaf cutting followed by 60 kg N/ha and one cut. The highest green leaf yield was recorded with 60 kg N/ha and two cuttings. The net return and B: C ratio were highest with 60 kg N/ha and one cutting.
