Abstract: A field experiment was conducted to study the “response of growth and development of safflower to green manuring, spacing and nitrogen levels under rainfed condition” was conducted in Northern dry zone (zone-3) of Karnataka, at Agriculture Research Station, Annigeri, UAS, Dharwad during kharif and rabi seasons of 2014-15 under rainfed condition. The experiment was laid out in a split-split plot design replicated thrice with 18 treatment combinations. Main plots consisted of three treatments, greengram for green manuring and greengram as a dual purpose both grown during kharif and one fallow. Succeeding safflower was sown during rabi season with two spacing of 45 cm x 20 cm and 60 cm x 30 cm as sub plots and three nitrogen levels 20, 30 and 40 kg N/ ha as sub-sub plot. The incorporation of green manures could further improve the productivity of safflower compared to keeping land fallow. The differential response of safflower to different green manures and spacing could be related to their differential response in terms of growth and Development.
