International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
cropping season has been covered as per Climate Resilient Agriculture Program (rabi-2021,
summer- 2021, kharif-2021 & rabi- 2021-2022). In all the selected villages, cropping cycle
has been covered as per crop calendar prepared as per Climate Resilient Agriculture Program
with the help of new generation machineries such as zero tillage multi crop-planter, new
turbo happy seeder, raised bed multi crop planter, drum seeder and rice wheat seeder for
timely showing of crop, to control weeds and pests (tractor mounted sprayers) have been used
for time saving and cost cutting.
While for timely harvesting and post-harvest management (SMS based harvester, straw
reaper as well as straw baller) is used for harvesting and effective residue management. In
CRA programme, eight cropping systems (Rice-Wheat-Mung bean; Rice-Lentil-Mung bean;
Maize-Wheat-Mung bean; Rice-Chickpea-Mung bean; Rice-Mustard-Mung bean; Pearl
Millet-Wheat-Mung bean; Soybean-Wheat-Mung bean; and Rice-Maize) were demonstrated
at farmers field as well at KVK farm of Katihar district relative to that of farmers practices
systems are compared and analyzed across the project site.
Results
Results showed that highest productivity was recorded in Rice - Maize- Mung bean
cropping system (160 ha -1 ) followed by Maize – Wheat – Mung bean (121 q ha -1 ), Rice –
Wheat – Mung bean (94 q ha -1 ), Soybean – Wheat – Mung bean (68.5q ha -1 ),Rice – Mustard
– Mung bean (67 q ha -1 ), Pearl Millet – Wheat – Mung bean (63.5 q ha -1 ), Rice – Lentil –
Mung bean ( 63.3 q ha -1 ) and lowest was recoded with Rice – Chickpea – Mung bean ( 63 q
ha -1 ) . However, in case of district average productivity for rice – wheat cropping system 56 q
ha -1 , respectively. In case of profitability, Results showed that highest profitability recorded
in Rice - Maize- Mung bean cropping system (233800 Rs. ha -1 ) followed by Rice – Wheat –
Mung bean (167100 Rs. ha -1 ), Soybean – Wheat – Mung bean (154650 Rs. ha -1 .), Maize –
Wheat – Mung bean (152800 Rs. ha -1 ), Rice – Lentil – Mung bean (150260 Rs. ha -1 ), Rice –
Chickpea – Mung bean (148700Rs. ha -1 ), Rice – Mustard – Mung bean (144600 Rs. ha -1 ),
and lowest was recoded with Pearl Millet – Wheat – Mung bean (116700 Rs. ha -1 ). Rice -
Maize- Mung bean cropping system with CRA intervention recorded highest productivity
(160 ha -1 ) and profitability (233800 Rs. ha -1 ). Thus, we can say that CRA intervention is
essential at present changing climate.
