Effects of integrated nutrient management on sucrose phosphate synthase enzyme activity and grain quality traits in rice.

Unlabelled: Cropping systems and management practices can greatly affect rice crop, finally determining their grain yield and quality. In this study, we evaluated the effects of integrated nutrient management practices on sucrose phosphate synthase enzyme (SPS) activity and grain quality traits of rice. Field experiments were conducted at North Bank Plain Agro-climatic Zone of Assam, India from 2013 to 2015 on three rice ecosystems (winter, summer, and pre-monsoon).

Impacts of integrated nutrient management on methane emission, global warming potential and carbon storage capacity in rice grown in a northeast India soil.

Rice soil is a source of emission of two major greenhouse gases (methane (CH) and nitrous oxide (NO)) and a sink of carbon dioxide (CO). The effect of inorganic fertilizers in combination with various organics (cow dung, green manure (Sesbania aculeata) Azolla compost, rice husk) on CH emission, global warming potential, and soil carbon storage along with crop productivity were studied at university farm under field conditions. The experiment was conducted in a randomized block design for 2 years in a monsoon rice (cv.

Genotypic variation in carbon fixation, δC fractionation and grain yield in seven wheat cultivars grown under well-watered conditions.

Biotic carbon (C) sequestration is currently being considered as a viable option for mitigating atmospheric carbon dioxide (CO2) emission, in which photosynthesis plays a significant role. A field experiment was conducted between 2013 and 2015 to investigate the efficiency of seven modern wheat varieties for CO2 fixation, C partitioning, δ13C fractionation in the leaves, and grain yield. A strong correlation between flag leaf photosynthesis and stomatal density (r=0.
