International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Results
Results revealed that the average paddy yield was enhanced by 91.3 percent from 21.6 to
41.32 q/ha and the seed yield of field pea was 11.54 q/ha. The system productivity of 52.86
qREY /ha in the paddy-pea cropping system was recorded which might be due to the
introduction of HYV of paddy and additional yield from field pea under raised beds in rice
fallow. The enhancement of net return fetched from Rs.14, 830 to Rs.76476/ ha with a
profitability ratio of 2.44 in the paddy-pea cropping system and increased the cropping
intensity from 100 to 200 percent (Table 2). Islam et al. (2020) and Samant T.K. (2015) also
reported that the inclusion of pulses in maize and rice-based crop sequences improved the
system productivity, profitability, resource use efficiency, and cropping intensity from
monocropping to double cropping.

Conclusion
The pea planted on the raised beds escaped crop losses due to temporary water logging and
offers significant opportunities for intensification and diversification along with the
utilization of paddy fields after harvesting to regenerate soil nutrients through leguminous pea
plants. The successful demonstration of climate resilient paddy –pea cropping system in
raised beds was realized by following the principles of “learning by doing” and “seeing is
believing” which helped the farmers to grow peas successfully after Kharif paddy instead of
keeping the rice field fallow during rabi season. The impressive performance of the
technology awakened the farmers, farm women, and rural youths of the village as well as
neighbouring villages to adopt this resilient technology for the second crop after paddy as it
helps to increase the cropping intensity, fetched higher net income and also better
reconciliation under the climatic stress condition. It was concluded that the existing ricebased
cropping system can effectively be diversified with the inclusion of legumes to
diversify rice-based mono-cropping into rice-field pea/pulses cropping system which had
nutrient cycling advantages. Hence, the climate-smart crop diversification in rice fallow
under raised beds enhanced system productivity, profitability, and cropping intensity
spreading to six neighboring villages covering 125 ha area in Ri Bhoi district of Meghalaya.
