Front line demonstrations were conducted in Uttara Kannada district of Karnataka state during Kharif season in the year 2017, 2018 and 2019 to increasing rice productivity and income by replacement of Abhilash old variety with promising high yielding improved variety PSB-68 and traditional practice with integrated crop management. Study revealed that over the years, PSB-68 Paddy variety with integrated crop management approach was superior over Abhilash variety with farmer practices. The higher plant height, number of tillers, panicle length, number grains per panicle, grain weight per panicle, grain yield and straw yield were recorded in demonstrated plot as compared to farmer practice. The gross returns, net return and B: C ratio were higher in demonstrated plot. The pooled data indicated that there was increase of grain yield by 42.12 % and straw yield by 30.53% over farmers practice. Similarly, the gross returns and net returns were increased by 41.41% and 75.50%, respectively. Data reported that there was reduction of incidence of insect pest viz., stem borer, leaf folder, brown plant hopper and ear head bug and diseases viz., blast, brown spot and grain discoloration with plots receiving integrated crop management. Whereas, farmers practice plot recorded higher incidence of insect pest and disease.
