Growth, Metabolism and Yield of Rice Cultivated in Soils Amended with Fly Ash and Cyanobacteria and Metal Loads in Plant Parts

Soil amendment with fly ash（FA） and combined supplementation with N_2-fixing cyanobacteria masses as biofertilizer were done in field experiments with rice. Amendments with FA levels, 0, 0.5, 1.0, 2.0, 4.0, 8.0 and 10.0 kg/m2, caused increase in growth and yield of rice up to 8.0 kg/m2, monitored with several parameters. Pigment contents and enzyme activities of leaves were enhanced by FA, with the maximum level of FA at 10.0 kg/m2. Protein content of rice seeds was the highest in plants grown at FA level 4.0 kg/m2. Basic soil properties, p H value, percentage of silt, percentage of clay, water-holding capacity, electrical conductivity, cation exchange capacity, and organic carbon content increased due to the FA amendment. Parallel supplementation of FA amended plots with 1.0 kg/m2 N_2-fixing cyanobacteria mass caused further significant increments of the most soil properties, and rice growth and yield parameters. 1000-grain weight of rice plants grown at FA level 4.0 kg/m2 along with cyanobacteria supplementation was the maximum. Cyanobacteria supplementation caused increase of important basic properties of soil including the total N-content. Estimations of elemental content in soils and plant parts（root and seed） were done by the atomic absorption spectrophotometry. Accumulations of K, P, Fe and several plant micronutrients（Mn, Ni, Co, Zn and Cu） and toxic elements（Pb, Cr and Cd） increased in soils and plant parts as a function of the FA gradation, but Na content remained almost unchanged in soils and seeds. Supplementation of cyanobacteria had ameliorating effect on toxic metal contents of soils and plant parts. The FA level 4.0 kg/m2, with 1.0 kg/m2 cyanobacteria mass supplementation, could be taken ideal, since there would be recharging of the soil with essential micronutrients as well as toxic chemicals in comparative lesser proportions, and cyanobacteria mass would cause lessening toxic metal loads with usual N_2-fixation.

Life cycle greenhouse gas emissions from five contrasting rice production systems in the tropics

引用

Pedosphere 2023年第6期33卷 960-971页

作者： Pradeep K.DASH Pratap BHATTACHARYYA Soumya R.PADHY Amaresh K.nayak Annie POONAM Sangita MOHANTY Crop Production Division Indian Council of Agriculture Research(ICAR)-National Rice Research Institute(NRRI)GuttackOdisha 753006India

Carbon footprint (CF) quantification of major rice production systems (RPSs) is a prerequisite for developing strategies for climate change mitigation in agriculture. Total life cycle greenhouse gas emissions (LC-GHGs) from rice production to consumption might provide precise CFs for RPSs. Therefore, we assessed three segments (pre-farm, on-farm, and post-farm) of LC-GHGs under five major contrasting RPSs, i.e., aerobic rice (AR), shallow lowland rice(SLR), system of rice intensification (SRI), deep water rice (DWR), and zero-tilled direct-seeded rice (ZTR), in India to determine the corresponding *** footprint was the lowest for ZTR, while LC-GHGs were the lowest for AR. Therefore, AR is an adequate option for short-term reduction of GHG emissions. However, ZTR might be promoted by incentives as a long-term strategy. Among segmental LC-GHGs, on-farm GHG emissions contributed less than the other two segmental GHG emissions. The post-farm (i.e., farm gate to consumption) segment contributed the largest proportion (54%–69%) of total LC-GHGs, followed by pre-farm (i.e., cradle to farm) segment (21%–27%) and on-farm operation (11%–23%). These findings suggest that post-farm components that contribute to maximum GHG emissions must be scientifically tackled with proactive policy initiatives. However, the data of this segment are limited and scattered. Therefore, real-time assessment of GHG emissions during post-farm operation and input transportation from cradle to farm requires more precise quantification. Although CF in SRI was higher, this system had the potential to achieve higher yields and better soil carbon storage. Therefore,SRI may be encouraged from the perspectives of food security and long-term sustainability by reducing GHG emissions by three to four times.

Clean India

引用

Journal of Geoscience and Environment Protection 2015年第5期3卷 133-139页

作者： Aparna nayak University of Idaho Boise USA

Mahatma Gandhi was mindful of the poor position of Indian rural people at that time and he dreamt of a cleaner India, where he emphasized on cleanliness and sanitation as an intact function of surviving. President Pranab Mukherjee in his address to Parliament in June 2014, said, “For ensuring hygiene, waste management and sanitation across the nation a “Swachh Bharat Mission” will be established. This will be our tribute to Mahatma Gandhi on his 150th birth anniversary to be celebrated in the year 2019”. The Narendra Modi Government will shortly establish the “Swachh Bharat” movement to solve the sanitation problem in India, to solve the problem of waste management and make India a clean state, ensuring hygiene all across the nation. Emphasizing “Clean India” on August 15, 2014 in his Independence Day speech, the Prime Minister said that this trend is linked with the economic activity of the state. This missionary work for creating a clean India will be launched on October 2, 2014, the birth anniversary of Mahatma Gandhi with the objective of completing the mission in 2019, the 150th birth anniversary of the father of the country.
