The present study was conducted in two taluks of Raichur district in Karnataka state during 2014-15 to analyse the perception and knowledge of paddy growers towards improved production technologies. The total sample constituted 180 paddy growers comprising of 60 marginal farmers, 60 small farmers and 60 big farmers from 12 villages of two taluks in Raichur district. Data was collected from 180 paddy growers using pre-tested interview schedule. The results revealed that 42.22 per cent of paddy growers had high level of perception, whereas 32.78 and 25.00 per cent of paddy growers had medium and low level of perception towards improved production technologies, respectively. Most of the paddy growers (37.78%) belonged to high knowledge level category, while 32.22 and 30.00 per cent of the paddy growers were belonging to medium and low knowledge categories, respectively. Education, farming experience, innovative proneness, achievement motivation and mass media exposure of paddy growers had significant association with their perception and knowledge level. 52.00 per cent and 71.20 per cent of the variation in perception and knowledge of paddy growers respectively could be explained by the selected 17 independent variables. Nonavailability of labours, lack of knowledge to manage the diseases and low price of the product were the major management, technical and marketing problems faced by paddy growers respectively. Providing agricultural inputs and machines on hire basis and providing efficient credit facilities were the important suggestions of paddy growers to overcome the problems.
