Abstract
The present investigation was carried out to analyze the performance and yield gap between improved variety (Kadiri Lepakshi) and farmerâs practice (K-6) during 2020-21 and 2021-22 in rain shadow region of Ananthapuram. The highest average pod yield was obtained with improved variety, Kadiri Lepakshi (1907kg ha-1), followed by K-Harithandra (1387 kg ha-1) compared to farmerâs practice (1053kg ha-1). The highest haulm yield was observed with Kadiri Lepakshi followed by K-6 and K-Harithandra. The average extension gap, technology gap and technology index during 2020-21 were 909 kg ha-1, 126 kg ha-1 and 5.6 respectively in Kadiri-Lepakshi. Whereas, during 2021-22 the average extension gap, technology gap and technology index were1050 kg ha-1, 360 kg ha-1 and 1.6 respectively. The per cent increase in yield was 74.8, 33.7 and 125, 36.9 of K-1812 and K-Harithandra during 2020-21 and 2021-22 respectively.
