International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Although the soil aggregate was significantly affected by organic amendments, but the
maximum Mean weight diameter (MWD) was observed in T8 followed by T7, T6, and T4 at
the soil depths of 0-15 cm. A similar trend was observed in the other depths. The
concentration of Zn, Mn, Fe, and Cu was found significantly higher in 0-15 cm soil depth as
compared to other depths. Our results clearly indicated that the cumulative effect of
GM+FYM+BGA leads to increased productivity, improved soil physical properties, and as
well as micronutrient availability.

Climate change is undoubtedly induced and accelerated by human activity and can pose a
serious threat to mankind by reducing food production. Significant weather aberrations in
form of the uneven precipitation pattern, more frequent and intense occurrence of
temperature fluctuations accompanied by changes in wind intensity and frequency, amount of
clouds, intensity and quality of sunlight can be expected. Maybe the most vulnerable sector
affected by climate change is agriculture. So, it is important to mitigate and adapt to a new
situation through different and most adaptable agricultural strategies. There is a need to
quantify agriculture’s potential to sequester carbon (C) to inform global approaches aimed at
mitigating climate change effects. Many factors including climate, crop, soil management
practices, and soil type can influence the contribution of agriculture to the global carbon
cycle. Conservation agriculture is as an approach to farming that seeks to increase food
security, alleviate poverty, conserve biodiversity and safeguard ecosystem services.
Conservation agriculture practices can also contribute to making agricultural systems more
resilient to climate change. Conservation agriculture increases and sustains the crop
productivities, mitigates greenhouse gas emissions from agriculture by enhancing soil carbon
sequestration, improving soil nutrient status and water use efficiencies, and reducing fuel
consumption. Mainstreaming of Conservation agriculture systems in India is hindered by its
knowledge gap, inadequate farm machineries and tools, small holdings, poor infrastructures,
and lack of conservation agriculture friendly policy support.
