Welcome to NICRA

Eddy covariance system for monitoring carbon dioxide, methane and other meteorological parameters

       National Initiative on Climate Resilient Agriculture (NICRA) is a network project of the Indian Council of Agricultural Research (ICAR) launched in February, 2011. The project aims to enhance resilience of Indian agriculture to climate change and climate variability through strategic research and technology demonstration. The research on adaptation and mitigation covers crops, livestock, fisheries and natural resource management. The project consists of four components viz. Strategic Research, Technology Demonstration, Capacity Building and Sponsored/Competitive Grants 

      The project was formally launched by the Hon’ble Union Minister for Agriculture & Food Processing Industries Shri Sharad Pawarji on 2^nd February 2011. Most of the activities across India were initiated in full measure during 2011-12.

N-Use Efficiency and N₂O emissions:

At CRRI, field experiments were conducted during kharif 2011 on the impact of nutrient management practices in paddy on GHG emissions. Peak N₂O emissions were observed 2-3 days after fertilizer application. Highest emissions (213 µg m^-2 hr^-1) were recorded with Swarna sub-1 variety and 120 kg N/ha fertilizer dose at 67 days after transplanting. Depending upon N treatment and variety, total seasonal emissions ranged from 0.78 kg ha^-1 to 2.5 kg ha^-1. Highest yield (averaged varieties) was observed under T₂ followed by T₃ and T₁. Global warming potential (GWP) per unit yield under T₃ lower than the T₂ in both the varieties.

An open path Eddy covariance systems having the carbon dioxide and methane sensor were installed at CRRI, Cuttack. The system measures the real time fluxes of CO₂ and CH₄ along with the relevant meteorological parameters in half an hour interval throughout the year.

Diurnal pattern

Diurnal pattern of Net ecosystem CO₂ exchange (NEE) over the entire kharif season, 2012 at CRRI [Negative NEE represents CO₂ fluxes from atmosphere towards the rice field (CO₂ absorption or uptake by rice), whereas positive NEE represents CO₂ fluxes from rice field towards the atmosphere (CO₂ emission from the rice field)]
