International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
The crop was sown during 2 nd F.N of June to 1 st F.N of July and harvested at maturity during
1 st fortnight of October in both the years. The method demonstrations were conducted on BMP
sat fields of beneficiary farmers. The yield data recorded from 5m × 5m plot in demonstration
and farmers’ practice and field days at harvest were conducted. The data on yield and
economics were tabulated and analyzed year wise. Further, from the yield data in the study
area extension gap, technology gap and technology index were worked out using the following
formulae (Samui et al., 2000).
Results
In demonstration plots the average pod yield of dharani variety was 818 kg ha -1 (ranged from
700 to 1060 kg ha -1 ) and 1355 kg ha -1 (ranged from 1254 to 1545 kg ha -1 ) during 2017-18 and
2018-19, respectively (Table). The technological interventions have resulted in an increase in
yield by 22.1 and 8.7 per cent, respectively during 2017-18 and 2018-19 over farmers practice.
These results are in similarity with the results reported by Yogesh et al. (2018) in groundnut
and Mohan et al. (2019) in Cluster FLDs in sunflower. From the two years data, the mean cost
incurred for implementation of BMP’s in demonstration plot was higher by Rs.1375/- ha -
1
compared to farmers practice which resulted in 24.0 percent higher net returns per hectare
with mean B:C ratio of 1.99 in demonstration plot.
