Rice Intensification

A field experiment was carried out at Agriculture Farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, India during kharif season of 2015 to compare rice cultivation in conventional transplanting (CT) and system of rice intensification (SRI) in terms of energy use, energy input output relationship and green house gas emission. Results showed that regardless of cultivars, conventional transplanting consumed 62.39% higher energy over SRI. Maximum energy input was associated with non renewable and indirect sources. Higher dose of nitrogenous fertilizer had contributed to 32.35% and 26.26% to the total input energy in CT and SRI respectively. Energy use efficiency (13.22), energy productivity (6.94 kg MJ-1), energy profitability (12.22) and energy intensity (4.60 MJ Rs-1) of hybrid rice varieties were noted higher in SRI. Maximum green house gas emission from rice field was also attributed to fertilizer nitrogen followed by diesel in both the system. Total green house gas emission in CT was estimated to 834.85 (kg CO2ha-1) i.e. 1.8 times of SRI. Engirdling different energy indices, total input energy and green house gas emission, the system of rice intensification was emerged as the most energy efficient and sustainable rice production system in resource stricken areas (Red Lateritic Zone).

Footprint Analysis

The Green House Gas Emission (GHGs) from the carp culture ponds (n = 12) of West Godavari, Krishna, and Guntur districts of Andhra Pradesh and from the ponds (n = 4) of Moyna, East Medinipur district of West Bengal, India was assessed through carbon storage and carbon footprint analysis. The average inputs as Carbon Equivalent (CE) were 14407 ± 2651, and 9231 ± 1007 kg/ha in Andhra Pradesh, and West Bengal, respectively. The average carbon storage were 6216 ± 2291, and 5360 ± 1439 kg/ha, in Andhra Pradesh, and Moyna, West Bengal respectively. The emissions of CO2-e and CH4-e were 1.91 ± 0.42 kg CO2-e/kg fish and 0.122 ± 0.027 kg CH4-e/kg fish, respectively in Andhra Pradesh. The emissions of CO2-e and CH4-e were 0.006 to 2.07 (average 0.72) kg CO2-e /kg fish, and 0.0004 to 0.132 (average 0.046) kg CH4-e /kg fish production, respectively in Moyna, West Bengal.
