Impact on Yield of Dill (Anethum graveolens L.) as Influenced by Nitrogen and Row Spacing

Field experiments were conducted during rabi season of 2004–05 to 2005–06 at Department of Vegetable Science, Kalyanpur, C.S. Azad University of Agriculture and Technology, Kanpur on dill seed spices crop with objective to find out effect of nitrogen and row spacing on the growth and yield of dill (Anethum graveolens L.). Experiments were carried out in randomized block design with three replications. There were fifteen treatment combinations of factor (a) nit ogen (0, 25, 50, 75, 100 kg/ha) and factor (b) row spacing (30, 37.5 and 45 cm). The crop was sown in first fortnight of November. The soil of the experimental plot was sandy loam. Basal application of phosphorus @ 50 kg/ha was applied as a common dose at the time of last ploughing. Results showed that the closest row spacing of 30 cm gave substantially higher seed yield than those of 37.5 cm and 45 cm spacing during both the years of investigations. Application of nitrogen @ 75 kg/ha produced significantly higher seed yield of dill as compared to all other doses of nitrogen. Characters like primary, secondary and tertiary branches per plant increased significantly with increase in the application of nitrogen levels and row spacings.
