OPTIMIZING FIELD PRODUCTION OF DILL
The effect of row width, plant spacing, and nitrogen fertilizer on growth of dill Anethum graveolens L. weed was investigated. Highest yields were obtained at the narrowest row width (15 cm) and closest plant spacing within the row (10 cm between plants) tested. The addition of nitrogen fertilizer increased plant growth with almost twice the production of fresh weight per plant at 120 kg nitrogen per hectare as compared with no added nitrogen.
