India has a total total geographical area 329 mha.Out of the 329 mha, the arid and semi- arid zones occupy more than one-third of the area (127.4 mha). The salt affected soils occurring in these zones occupy 12 mha area spread over in 15 states of the country, out of which 4.12 mha are alkali, 3.26 mha are saline soils and 4.62 mha saline alkali soils.Safflower (Carthamus tinctorius L.) is considered to be a moderately salt-tolerant crop.The field experiment was conducted during rabi,2017 at Bhavanamvaripalem farmer’s safflower fields on sandy clay loam soil in randomized block design with five treatments and four replications.This study indicated that there is a scope of increasing crop yields through use of integrated nutrient management in safflower. Application of gypsum + FYM + 25% additional nitrogen resulted in better yield attributing characters and yield followed by gypsum+25% additional nitrogen treatment while, the lowest yield was recorded in farmers practice.
