Description An experiment was conducted during rabi season of 2008-09 at Farm, College of Horticulture, Mandsaurto study the effect of spacing and nitrogen on the productivity and quality of ajowan. The experiment wasconsisting of 3 spacing (45 x 10 cm, 45 x 20 cm and 45 x 30 cm ) and 4 levels of nitrogen (0, 20, 40 and 60 KgN ha-1). Wider 45 x 30 cm spacing significantly increased the number of primary and secondary branches perplant at harvest, fresh weight per plant (g), dry weight per plant, days to 50% flowering, number of umbelsper plant, number of umbellets per umbel, yield per plant (g) chlorophyll content of leaves (mg g-1), carotenoidscontent of leaves (mg g-1) and essential oil of seed (ml 100 g-1) expect plant height (cm), seed yield (q ha-1),straw yield (q ha-1) and biological yield (q ha-1), these attributes are maximum in 45 x 10 cm spacing. Whereasnon significant effect was observed on test weight (g) and harvest index (%). Among various levels of nitrogentried 60 kg ha-1 exhibit growth, yield and quality attributes. The maximum benefit: cost ratio (6.26:1) wasfound with “45 x 30 cm + 60 Kg N ha-1” treatment combination.
