The present investigation was carried out in Prakasam district of Andhra Pradesh during the year 2015-16 toassess the technological gap in adopting recommended rice production technology by the farmers. Fifty one per cent of ricefarmers belonged to medium category of technological gap followed by 26.67 and 22.22 per cent low and high technologicalgap, respectively. Major technological gap was observed with respect to adoption of bio fertilizers (77.78 %), maintainingnumber of seedlings per square meter (76.67%), time of phosphorus fertilizer application (74.73 %), nitrogen fertilizerquantity (68.27 %), time of potash fertilizer application (67.51%), phosphorus fertilizer quantity (67.22 %), zinc management(66.56 %), number of seedlings per hill (65.56 %), time of application of nitrogen fertilizers (64.83 %), organic fertilizers(63.33 %), irrigation (62.83 %), seed treatment (62.78 %), nursery management (55.00 %), pest management (54.88%),quantity of potash application (54.45 %) and age of the seedlings for transplantation (51.11 %). Majority of the ricegrowing farmers were middle aged with high school education, medium land holding, farming experience, mass mediaexposure, innovativeness, social participation, economic motivation, extension participation and trainings undergone.Trainings undergone, mass media use, innovativeness, education and extension participation were having negative correlationwith technological gap at 1 per cent level of significance. Majority of the farmers expressed constraints viz., increased costof cultivation (92.22 %), labour intensive crop (84.44 %), more prevalence of pest and diseases (78.89 %), low yields(76.67 %), non availability of transplanting machines locally (74.44 %), late release of canal irrigation water (72.22 %), highcost of inputs (65.56 %), micro nutrient deficiencies (62.22 %), insufficient Minimum Support Price (60.00%), insufficientinorganic fertilizers availability (56.67 %), non availability of pest and disease resistant varieties (52.22 %) in rice cultivation.
