“…Such results are in good agreement with that of Ray et al [5], who worked on different rice-based systems in the Bankura district of the West Bengal state. Higher energy use efficiency of rice-potato systems has also been confirmed by Soni et al [38]. Higher input energy of these systems was mainly contributed by fertilizer, diesel fuel use and seed energy (Fig 5).…”

This study compares thirteen rice-based cropping systems in the coastal part of West Bengal, India in terms of productivity, profitability, energetics, and emissions. Information on the crop management practices of these systems was collected on 60 farms through a questionnaire survey. Rice-bitter gourd system was observed to have the highest system yield (49.88 ± 4.34 tha −1 yr −1) followed by rice-potato-ridge gourd (37.78 ± 2.77 tha −1 yr −1) and rice-potato-pumpkin (36.84 ± 2.04 tha −1 yr −1) systems. The rice-bitter gourd system also recorded the highest benefit:cost ratio (3.92 ± 0.061). The lowest system yield and economics were recorded in the rice-fallow-fallow system. Rice-sunflower system recorded highest specific energy (2.54 ± 0.102 MJkg −1), followed by rice-rice (2.14 ± 0.174 MJkg −1) and ricefallow-fallow (1.91 ± 0.327 MJkg −1) systems, lowest being observed in the rice-bitter gourd (0.52 ± 0.290 MJkg −1) and rice-pointed gourd (0.52 ± 0.373 MJkg −1) systems. Yield-scaled GHGs (YSGHG) emission was highest (1.265 ± 0.29 t CO 2eq t −1 system yield) for rice-fallowfallow system and was lowest for rice-vegetable systems. To estimate the uncertainty of the YSGHG across different systems under study, Monte-Carlo Simulation was performed. It was observed that there was a 5% probability of recording YSGHG emission > 1.15 t CO 2eq t −1 system yield from different cropping systems in the present experiment. Multiple system properties such as productivity, economics, energy, and emission from all ricebased systems taken together, the rice-vegetable system performed consistently well across parameters and may be practised for higher economic returns with judicious and sustainable utilization of resources in the coastal saline tracts of the region.

“…The net energy gain is simply a balance sheet between output and input energies. Energy use efficiency is used to express the effectiveness of an agricultural production system, whereas energy efficiency ratio considers the main product as a contributor to the pool of output energy [34,37]. Specific energy is an estimated yield as a function of input energy, where a higher value indicates lower efficiency of crop or cropping system.…”

Sustainability and climate change are the two major challenges to the agricultural production system. The trade-off between them is essential for higher profitability. The energy assessment is essential for judging the sustainability and vulnerability of a production system. Besides, nutrient management and weed management are equally imperative to sustainability. Thus, the present study was executed to assess the energy balance, key energy indicators and profitability of rice–maize–green gram system under different nutrient and weed management practices. Application of Brassicaceous seed meal (BSM) along with mineral fertilizer attributed the highest rice (5.62 t ha−1) and maize (6.48 t ha−1) yield which was 11.6%, 8.3% and 3.7% in maize and 10.0%, 6.2% and 8.7% in rice for the conjoint application with vermicompost, farmyard manure (FYM) and neem cake, respectively. Moreover, BSM recorded the highest net energy gain, energy use efficiency and energy efficiency ratio and the lowest specific energy in all the crops. Application of pre-emergence herbicides followed by hoeing was found to be best in all respects including yield, profitability, energy use efficiency, energy effectiveness, etc. The appropriate combination of integrated nutrient management with BSM and pre-emergence herbicide application followed by hoeing provided an additional advantage not only in terms of yield but also an efficient use of energy, profitability and environmental safety. BSM and neem cake could be the alternative organic manure in the integrated nutrient-cum-weed management module and they could be able to compensate the paucity of FYM and vermicompost in the country.

“…Electrostatic spraying technology is a newer technology in the field of agriculture and effective in controlling the pest with impending reduction of over-application of chemicals [26,27,28]. It has an increased application efficiency of about 80 per cent with 60 per cent less spray chemical ingredients [29,30,31,32,33]. It works based on the principle of electrostatics, like charges repel and opposite charges attract (Coulomb's law).…”

This study aimed at finding out the efficacy of electrostatic sprayer on pest control in comparison with mist blower and air compression sprayer. Six pests were selected based on specific characteristics viz. integumental, movement and ecological niche. Energy use efficiency in production and application of pesticides used by different sprayers for the control of selected pests were quantified based on application efficiency, pre and post pest count and reoccurrence of pest infestation after spray. The greenhouse gas emission for the total energy usage for the corresponding quantity of pesticide were computed for all the selected sprayers. The energy use efficiency of electrostatic sprayer was found to be 1.5 times more than that of mist blower and 2 times more than that of air compression sprayers. The chemical usage by electrostatic sprayer was reduced by 65%, and that of knapsack mist blower was 35% with air compression sprayers. The corresponding greenhouse gas emission was only 20% for electrostatic sprayer and 65% for powered mist blower than that of air compression sprayers. The post pest count was almost nil in all the categories of pest while applying with electrostatic sprayer and the reoccurrence of the pest to the threshold level was minimum. This contributes a significant reduction in emission of CO2 when considered globally, and ultimately contribute to mitigation of global warming.
