International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
India rice is grown on an area of about 43.5 million ha with a total population of 105.5 MT and
productivity of 2.4 tons per ha during 2014-15. Increasing water scarcity, water loving nation
of rice cultivation and increasing labour wages triggers the search for alternative crop
establishment method which can increase water productivity. In traditional rice cultivation, rice
is sprouted in a nursery. Sprouted seedlings are then transplanted into standing water with
direct seedling, rice seed is sown and sprouted directly into the field, eliminating the laborious
process of planting seedlings by hand and greatly reducing the crops water requirement. Direct
seeded crops require less labour and tend to mature faster than transplanted crops.
Conventional method of rice growing which is not only intensive water user but also
cumbersome and laborious. Different problems like lowering water table, scarcity of labour
during peak periods, deteriorating soil health demands some alternative establishment method
to sustain productivity of rice as well as natural resources direct seeded rice, the olds method of
crop establishment, is gaining popularity because of its low-input demand. It saves labour,
requires less water, less drudgery, early crop maturity, low production cost, better soil physical
conditions for following crops and less methane emission, provides better option to be the best
fit in different cropping systems. There are several constraints associated with shift PTR to
DSR, such as high weed infestation, evaluation of weedy rice, increase in soil borne pathogens,
nutrient disorders, poor crop establishment, lodging, incidence of blast, brown leaf spot etc. by
overcoming these constraints DSR can prone to be a very promising, technically and
economically feasible alternative to PTR.

The impacts of climate change are evident in the agriculture sector in India. These impacts are
more severe and pronounced in a dry district like Ratlam due to the high reliance on agroeconomy
and subsistence-based livelihoods by smallholder farmers that increase vulnerability
and risks. This paper evaluated performance of BBF (Broad Bed Furrow), improved variety,
soil test based nutrient management system and integrated pest and diseases management, by
comparing their efficacy in terms of yield and reduction in disease pest problems.
Methodology
The trial was conducted in NICRA-adopted village of Ratlam district during 2020-21 and
2021-22on farmer’s field in soybean, chickpea and wheat crop. Before and after comparisons
Ecosystem based approaches for climate change adaptation, ecosystem services, integrated farming system
models, Land degradation neutrality
