An understanding of the dynamics of soil organic carbon (SOC) as affected by farming practices is imperative for maintaining soil productivity and also for restraining global warming by CO2 evolution. Results of a long-term (30 year) experiment in the Indian Himalayas under rainfed soybean (Glycine max L.)—wheat (Triticum aestivum L.) rotation was analyzed(More)
Thirty-one rice soils from different locations in the Philippines were incubated anaerobically for 100 d to determine methane (CH4) production potentials and to establish relationships between physico-chemical properties of soil and CH4 production potential. These soils showed pronounced variations in pattern and magnitude of CH4 production. Total CH4(More)
Methane (CH4) is one of the important greenhouse gases accounting for 15% of the total enhanced greenhouse effect. A laboratory experiment was conducted with nine soils from the Philippines and two soils from India to determine the CH4 production potential of topsoil and subsoil, and to assess the role of different fractions of soil organic C in influencing(More)
We studied the effects of tillage and straw management on soil aggregation and soil carbon sequestration in a 30-year split-plot experiment on clay soil in southern Finland. The experimental plots were under conventional or reduced tillage with straw retained, removed or burnt. Wet sieving was done to study organic carbon and soil composition divided in(More)
Molecular genetic fingerprints of eleven Hedychium species from Northeast India were developed using PCR based markers. Fifteen inter-simple sequence repeats (ISSRs) and five amplified fragment length polymorphism (AFLP) primers produced 547 polymorphic fragments. Positive correlation (r = 0.46) was observed between the mean genetic similarity and genetic(More)
Linkage map with wide marker coverage is an essential resource for genetic improvement study for any species. Sex-averaged genetic linkage map of Labeo rohita, popularly known as ‘rohu’, widely cultured in the Indian subcontinent, was developed by placing 68 microsatellite markers generated by a simplified method. The parents and their F 1 progeny (92(More)
The effect of urea and urea mixed with different doses of two nitrification inhibitors, dicyandiamide (DCD) and karanjin [a furanoflavonoid, extracted from seeds of the karanja (Pongamia glabra Vent.) tree], on methane (CH4) consumption was examined in a Typic Ustochrept (alluvial inceptisol) soil, collected from a field under rice-wheat rotation. The soil,(More)
Turmeric (Curcuma longa L.) is a domesticated cultivar belonging to the family Zingiberaceae and is widely used as spice, medicine and cosmetics. In the current paper, the genetic structure of nineteen commercial cultivars of turmeric of northeast (NE) India was assessed by molecular markers and their genome size. The average polymorphism, polymorphic(More)
Agricultural soils contribute towards the emission of CH4 (mainly from paddy fields) and N2O (from N-fertilizer application), the two important greenhouse gases causing global warming. Most studies had developed the inventories of CH4 and N2O emission at the country level (larger scale) for India, but not many studies are available at the local scale (e.g.(More)
