Abstract: Safflower (Carthamus tinctorius) growth and productivity are influenced by many factors such as genotype, environment and agronomic practices. A field experiment was conducted at Agriculture Research Station, Annigeri, University of Agricultural Sciences, Dharwad during kharif and rabi seasons of 2014-15 under rainfed conditions to study the Effect of Spacing and Nitrogen levels on Yield and Oil content of Rabi Safflower (Carthamus tinctorius) in Vertisols of South India. The experiment was laid out in a split-split plot design and replicated thrice. Main plot consists of three treatments, greengram as a green manuring, greengram as a dual purpose crop grown during kharif and one fallow. Succeeding safflower was sown during rabi season with two sub treatments of spacings (45 cm x 20 cm and 60 cm x 30 cm) and three sub sub treatments of nitrogen levels (20, 30 and 40 kg N/ ha). In different spacing treatments, significantly higher oil yield was observed in 60 cm x 30 cm (360.64 kg/ha) than 45 cm x 20 cm (315.77 kg/ha). Among the different nitrogen levels, significantly higher oil yield was observed at 40 kg N/ha (409.30 kg/ha) over the 30 kg N/ha (318.17 kg/ha) and 20 kg N/ha (287.13 kg/ha).
