Various irrigation regimes were applied to NC0376 over five years of low rainfall (average 466 mm per annum). Cane yield increased, depending on amount of water applied, from 84 to 122 t/ha. There was no significant effect on quality. The lowest application of 660 mm of irrigation produced 69% of the yield produced by the standard (full) irrigation (1 520 mm) at 12 months of age. There were no ...

The physical characteristics, microbial activities and kinetic properties of the granular sludge biomass were investigated under the influence of different hydraulic retention times (HRT) along with the performance of the system in removal of color and COD of synthetic textile wastewater. The study was conducted in a column reactor operated according to a sequential batch reactor with a sequenc...

In the current century, agriculture sustainability and the reduction of environmental pressure are two main objectives of the management of agro-ecosystems that is challenged by energy inefficiency. In this respect, the present study assessed one of the most important planting systems in Sistan region by emergy analysis approach. It analyzed all inputs of greenhouse cucumber production system i...

An experiment was conducted at the research farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh with the cucumber cv. Modumoti to evaluate the porpho-physiological characters and yield performance under four different levels of light (100, 75, 50 and 25% PAR). Significant differences were observed among the treatments in response to different evaluated characters. Main stem length,...

to determine the most important traits affecting root yield and sugar content in monogerm germplasm of sugar beet, 75 monogerm f1 hybrids were evaluated in three separate experments conducted in randomized complete block desing (rcb) with four replications at abdo–al–rasoul research farm, karaj in 2004. root yield, root length, root diameter, crown height, crown diameter, sugar content, α–amino...

      In order to study the effects of post-anthesis heat stress and nitrogen levels on grain yield and yield components of wheat genotypes, two separate field experiments were conducted in delayed and optimum sowing dates under Ahvaz conditions (2006-2007). The Ahvaz site located in south west of Iran (32°20' N, 40°20' E) with subtropical climate condition. The experiment site had a moderate w...

The synthesis of fluorescent water-soluble gold nanoparticles by the reduction of a gold salt in the presence of a designed polymer ligand is described, the size and fluorescence of the particles being controlled by the polymer to gold ratio; the most fluorescent nanomaterial has a 3% quantum yield, a 1.1 nm gold core and a 6.9 nm hydrodynamic radius.
