A field study was conducted during November 1999 to March 2000 on red sandy loam soil at GKVK, UAS, Bangalore to study the effect of irrigation intervals and planting geometry on growth and yield components of davana. Irrigation given at 15 mm CPE gave significantly higher growth components viz., plant height, number of branches per plant, total chlorophyll content, leaf area per plant, LAI and total dry matter accumulation and yield components viz., fresh weight per plant, fresh weight of flower head per plant, 100 flower head weight and flower head to biomass ratio. Wider spacing (45 cm X 15 cm) increased the above all growth and yield components except plant height and LAI which were found significantly higher with closer spacing (15 cm X 10 cm).
