Besides its great potential in controlling water pollution from different sources, waste water treatment system generates significant amount of greenhouse gases. Hence, reducing the emission of greenhouse gases from the wastewater treatment plants is the major concern. The correct understanding and estimation of the greenhouse gases emitted from different points of the plan is essential to tack...

In greenhouse studiesl infectivity and development of M. incoynila on tomato was impaired by increasing soil solution concentrations (ECe 1.5, 2.5, 3.5, 5.0 mmhos/cm) ol NaC1, CaCI, or combinations of both salts. In two experiments, reduced inlrctivily was pronounced on a susceptible cultivar (Hunts) a t all salt concentrations, while infectivity was reduced primarily a t higher salt concentrat...

Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

The host suitability of 64 commercial corn hybrids for a Meloidogyne arenaria race 2 population and a M. incognita race 4 population was determined in greenhouse experiments. 'Northrup King 508' and 'Pioneer Brand 3147' maintained M. arenaria below and at the initial population level, respectively, indicating that these hybrids are relatively poor hosts for this species. RF values (final egg nu...

abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...

Mathematical simulation model is very suitable to understand insect dynamical systems. This system is nonlinear and it is hard to deal with by pure mathematical models only. It offers a possibility to recognize possible gaps in our knowledge. A simulation model of immature stages development of greenhouse whitefly Trialeurodes vaporariorum (westwood) population is presented. The parameters, var...

This research studied recycled waste by the Recyclable Material Bank Project of 4 universities in the central region of Thailand for the evaluation of reducing greenhouse gas emissions compared with landfilling activity during July 2012 to June 2013. The results showed that the projects collected total amount of recyclable wastes of about 911,984.80 kilograms. Office paper had the largest amoun...

The effects of temperature and soil type on interstrain competition of Bradyrhizobium japonicum and on nodulation and nitrogen accumulation in five soybean varieties belonging to four maturity groups were investigated at three sites devoid of soybean rhizobia along an elevational transect in Hawaii. Competition patterns of the three B. japonicum strains were unaffected by soil type or soil temp...
