The objectives of the study were as follows: 1) to evaluate the GxExM for wheat genotypes;2) to predict yield performance and identify high stable wheat genotypes in different management practices;and 3) to make genotype-specific management and high performing genotype recommendations within and across agro-ecological regions. A diverse set of twenty-one genotypes was evaluated over three years (2012, 2013 and 2014) under two levels of crop management practices (CT and ZT) across three agro-ecological regions (BR, MP and PB) of India in replicated trials. Data were analyzed with SASGxE and RGxE programs using SAS and R programming languages, respectively. Across and within a location(s), the pattern of GxExM and GxMxY interactions (respectively) among univariate and multivariate stability statistics, grouping of genotypes in divisive clusters and estimates (with a prediction interval) of genotype varied in management practice CT and ZT. Across locations, the genotypes “Munal” and “HD-2967” were the best performers and high stable in CT and ZT, respectively. Genotypes “HD-2824” and “DPW-621-50”, and “Munal” may serve as diverse parents for developing high quality, climate smart, locally adapted genotypes for BR in CT and ZT, respectively. Genotypes “HD-2932”, “BAZ” and “JW-3288”, and “GW-322” and “HD-2967” are suitable for developing locally adapted stress tolerant genotypes for MP in management practices CT and ZT, respectively. Relatively small GxM and GxExM interactions in PB preclude in making definitive conclusions.

Iron pyrite has been reported as a kind of potential material for arsenic(As)removal from the groundwater because it exhibits a strong attraction in groundwater for both arsenite and arsenate *** this study,batch adsorption experiments were carried out to determine the optimum conditions for As adsorption by the iron pyrite adsorbent,including the initial concentration,adsorbent dosage ratio,pH,temperature and stirring *** characterization methods were employed to identify the mechanism of As *** removal efficiency for As(Ⅲ)was observed 93%at pH=7,and for As(Ⅴ)was 95%observed at pH=*** model resulted in the maximum adsorption capacity(q_(m))for As(Ⅲ)and As(Ⅴ)were 571.7 and 671.1μg/g,respectively,as well as the experiments were found to be favorable as separation factor R_(L)1)indicates favorable *** pseudo-first and second-order kinetic models also fitted *** addition of oxalate on the adsorbent surface plays an important role for the recycling of Fe(Ⅱ)/Fe(Ⅲ)to minimize the arsenic *** surface area,ion exchange mechanism and structure of adsorbent confirmed that addition of oxalate could enhance the surface area of adsorbent.
