International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
on various variables were obtained with the help of baseline data and recall memories of
respondents.
Results
The result was shows 25.93% yield increase in soybean due to introduction of extra early,
thermo-insensitive, multiple resistant and high yielding variety JS-2034, over traditional
practice with use of broad bed furrow (BBF) technology in Kharif season. Similarly in rabi
season- heat tolerant, wilt resistance and high yielding variety chickpea variety RVG-202 has
given higher yield of 19.8 % over traditional practice with use of BBF technology. Improved
high yielding and heat tolerant wheat variety HI-1605 given higher yield of 23.57 %
comparison to traditional variety LOK-1 with use of line show technology. These findings
suggest that traditionally used practices have scientific basis and offer simple, affordable and
climate friendly practices to improve the health of agro-ecosystem while supporting
smallholder farmers to adapt to adverse impacts of climate change and build socio-ecological
resilience. These practices can be also customized depending on the local context for wider
adoption and scaling. Similar result were also found by Aggarwal P. K. (2003), Das et al.
(2012 & 2014), Jasna et al. (2017), Parry et al. (2017) and Sonune & Mane (2018).

Conclusion
Broad Bed and Furrow technique and stress tolerant cultivars can play an important role in
coping with climate variability as well as enhancing the productivity. These findings suggest
that traditionally used practices have scientific basis and offer simple, affordable and climate
