abstract plant species differ in their ability to grow at low available p soils in other words, plant species differ in p use efficiency at low p supply. this ability can be investigated by comparing p uptake efficiency of plants and relative effective factors. a pot experiment was carried out in the growth chamber and sugar beet, maize and groundnut were grown in a low available p soil in a co...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

background: cardiac risk assessment with myocardial perfusion imaging (mpi) is a common practice for some elderly breast cancer patients who are candidates for operation. in rare cases the tumor may become visible in the images. case presentation: this is the report of a case with a huge slow-growing breast tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile (mibi) u...

the study applied an isolated brevibacterium sp. (mtcc 10313) for bioremediation of zn, cu, mg and pb in domestic sewage. batch culture experiments were performed on both the fresh and stale sewage samples with glucose supplementation of 1-8g/l. nutrient broth medium was prepared, sterilized and ph adjusted to 6.5-6.8. 1% of the brevibacteria sp. stock was inoculated into the broth and maintain...

fifteen kinds of local wetland plants in taihu lake region of china were investigated on their respective growth conditions, biomass allocations and nutrient uptake capacities. the test plants were cultured in 3 l nutrient solutions for 28 days with nh4 +-n, no3 --n and p concentrations of 38.5, 132.8 and 10 mg/l, respectively. mean species total biomass ranged from 1.2-21.6 g/plant with above/...
