In a field experiment, the effect of enhanced UV-B radiation (simulating 20% ozone depletion at Allahabad, 20 degrees 47' N latitude) was studied on two cultivars of Vigna radiata L. with various levels of mineral nutrients (N and P). Study showed decrease in total biomass accumulation, harvest index, RSR and yield after exposure with enhanced level of UV-B. RGR and CGR also showed decline afte...

The concentrations of sugars, starch, nutrients and some heavy metals were examined during the growing season in four tree species (Ailanthus glandulosa DESF., Carpinus betulus L., Tilia argentea DESF. and Quercus cerris L.), growing in natural and planted stands in a region with considerable industrial emissions and in an unpolluted area. Trees in the polluted regions had lower concentrations ...

Wetlands host complex microbial communities including bacteria, fungi, protozoa and viruses. The size and diversity of microbial communities are related directly to the quality and quantity of the resources (i.e., nutrients, energy sources) available in the system. Microbial biomass and activity is highest in habitats where these resources are concentrated, including periphyton mats, plant detr...

Legume cover crops have various important effects on nutrient cycling in tropical fruit tree production: they (i) fix atmospheric N2 and may amend the soil and trees with N, (ii) recycle nutrients, and (iii) affect soil nutrient availability. Aboveground N accumulation usually is very large in legume cover crops as seen from Pueraria phaseoloides being 8 to 14 times higher than in intercropped ...

Obesity is a state in which there is an over-accumulation of subcutaneous and/or abdominal adipose tissue. This adipose tissue is no longer considered inert and mainly devoted to storing energy; it is emerging as an active tissue in the regulation of physiological and pathological processes, including immunity and inflammation. Adipose tissue produces and releases a variety of adipokines (lepti...

High nutrient inputs and eutrophication continue to be one of the highest priority water quality problems. Bioretention is a low-impact development technology that has been advocated for use in urban and other developed areas. This work provides an in-depth analysis on removal of nutrients from a synthetic stormwater runoff by bioretention. Results have indicated good removal of phosphorus (70 ...

A kinetic metabolic model describing Catharanthus roseus hairy root growth and nutrition was developed. The metabolic network includes glycolysis, pentose-phosphate pathway, TCA cycle and the catabolic reactions leading to cell building blocks such as amino acids, organic acids, organic phosphates, lipids and structural hexoses. The central primary metabolic network was taken at pseudo-steady s...

Biological cycling of macro-nutrients (N, P, K, Ca, Mg and S) were studied by synthesizing the previous new data from Bruguiera parviflora dominated mangroves at Kuala Selangor Nature Park, Malaysia. The total stock annual accumulation N, S in plant biomass 60.11 kg ha-1y-1; 11.48 ha-1y-1, 36.25 72.75 31.32 ha-1y-1 82.12 respectively. return form litter fall 59.82 ha-1, 10.93 23.43 118.31 29.25...

The study was carried out in the winter (rabi) season to determine effect of Nano and Non-nano nutrient, study's findings revealed that wheat grown with 100% NPK + nano nutrients (N P K Zn) had significantly higher uptake, namely N (143.1 kg ha-1), (28.9 (109.0 Zn (519.5 g ha-1). Applications nutrients—N, P, K, Zn, 75% NPK—worked synergistically increased content uptake over NPK. Similarly, agr...

BACKGROUND AND AIMS Crop yield and nutritional quality are significantly reduced when potassium (K) in soil is deficient. As a beneficial element for plants, silicon (Si) is effective in alleviating the toxic effects of mineral nutrients. However, the roles played by Si in mediating deficiency in essential mineral nutrients in general and K in particular have not been investigated. METHODS To...
