Abstract: Frontline demonstration in pigeonpea is to popularize the improved package of practices in farmers field in order to assess the impact of technology transfer and to identify the lacuna in recommended technology with the traditional farming practices. In order to boost the productivity in Vellore district, Tamil Nadu, Agricultural Research Station, Virinjipuram has conducted 20 frontline demonstration in pigeonpea during kharif season 2018-19 and 2019-20. The results were compared with the introduction of a new variety along with the newer technologies with farmers practice. The results on frontline demonstration studies revealed that, an average grain yield of 1300.20 and 1342.0 kg ha^-1 was obtained in demonstrated plots during 2018-19 and 2019-20, respectively as against the farmers practice which recorded 881.20 and 950.80 kgha^-1, respectively with 47.50 and 41.14 per cent increase over farmers practice. During the demonstration, various gaps such as technology gap reported as 299.80 and 258.0 kgha^-1 during 2018-19 and 2019-20, respectively. The highest extension gap of 419.0 kgha^-1 was observed during 2018-19 and 2019-20 (391.20 kg ha^-1), which shows more emphasize to educate the pigeonpea farmers through various means of adoption. The technology index showed the feasibility of the demonstrated technology in farmers field and varied from 21.20 to 18.66 per cent. With the use of improved package of practices on an average additional investment of Rs.3700/- ha^-1 and Rs. 4400/- ha^-1 was made for demonstration. The excess expenditure incurred resulted in the highest net return in demonstration plots of Rs. 40,500/- ha^-1 as compared to farmers practice of Rs.23,260/- ha^-1 with 42.56 per cent increase in net return and Rs. 42,200/- ha^-1 as compared to farmers practice of Rs.27,040/- ha^-1 with 35.92 per cent increase in net return over farmers practice during 2018-19 and 2019-20, respectively.
