Abstract

A field experiment was conducted during rabi 2007-08 to study the response of Coriander (Coriandrum sativum L.) to different levels of seed rate (25, 31.25 and 37.5 kg/ha) and nitrogen ((37.5, 75, 112.5 and 150 kg/ha) grown in association with five year old Poplar spaced at 5x4 m. The height and dbh of Poplar was 17.58 m and 18.27 cm respectively. The Coriander crop intercropped with Poplar responded positively to higher seed rate and nitrogen levels than recommended to sole crop. Increasing levels of nitrogen from 37.5 to 112.5 kg/ha and seed rate from 25 to 31.25 kg/ha increased all growth and yield attributes and recorded significantly more seed and straw yields. The interaction between seed rate and nitrogen was significant for plant height, umbels per plant, 1000 seed weight, straw and seed yield. The combination of 31.25 kg/ha seed rate and 112.5 kg/ha N gave highest seed yield of 5.83 q/ha which was 33.3% more than that obtained with recommended seed rate (25 kg/ha) and nitrogen level (75 kg/ha).
