Nickel (Ni) toxicity in agricultural crops is a widespread problem while little is known about the role of biochar (BC) and other organic amendments like farm manure (FM) from cattle farm and compost (Cmp) on its alleviation. A greenhouse experiment was conducted to evaluate the effects of BC, Cmp and FM on physiological and biochemical characteristics of maize (Zea mays L.) under Ni stress. Maize was grown in Ni spiked soil without and with two rates of the amendments (equivalent to 1% and 2% organic carbon, OC) applied separately to the soil After harvest, plant height, root length, dry weight, chlorophyll contents, gas exchange characteristics and trace elements in plants were determined. In addition, post-harvest soil characteristics like pH(s), ECe and bioavailable Ni were also determined. Compared to the control, all of the amendments increased plant height, root length, shoot and root dry weight with the maximum increase in all parameters by FM (2% OC) treatment. Similarly, total chlorophyll contents and gas exchange characteristics significantly increased with the application of amendments being maximum with FM (2% OC) application. Amendments significantly increased copper, zinc, manganese and iron concentrations and decreased Ni concentrations in the plants. The highest reduction in shoot Ni concentration was recorded with FM (2% OC) followed by BC (2% OC) being 73.2% and 61.1% lower compared to the control, respectively. The maximum increase in soil pH and decrease in AB-DTPA extractable Ni was recorded with BC (2% OC) followed by FM (2% OC). It is concluded that FM (2% OC) was the most effective in reducing Ni toxicity to plants by reducing Ni uptake while BC (2% OC) was the most effective in decreasing bioavailable Ni in the soil through increasing soil pH. However, long-term field studies are needed to evaluate the effects of these amendments in reducing Ni toxicity in plants. (C) 2016 Elsevier Inc. All rights reserved.

Investigating the potential influence of biochar and traditional organic amendments on the bioavailability and transfer of Cd in the soil-plant system Yousaf, Balal; Liu, Guijian; Wang, Ruwei; Zia-ur-Rehman, Muhammad; Rizwan, Muhammad Shahid; Imtiaz, Muhammad; Murtaza, Ghulam; Shakoor, Awais (2016-03-01) In this paper biochar (BC) and traditional soil amendments, including press mud (PrM), farm manure (FM), compost (Cmp), poultry manure (PM) and sewage sludge (SS), were evaluated as carbon sources (20 g kg(-1) organic carbon) to assess their ability to store soil organic carbon as well as their effects on the bioavailability, transfer and immobilization of Cd in contaminated soil. Wheat (Triticum aestivum L.) was grown on unamended and amended soil (at 2 % organic carbon basis) in a greenhouse experiment an...
Application of virus induced gene silencing of brachypodium distachyon, a model organism for crops Demircan, Turan; Akkaya, Mahinur S.; Department of Biochemistry (2009) Grass family is most important family in plant kingdom due to intensive usage of crops in agriculture. To date, molecular biology researches on grass family have had limitations because of inappropriate characteristics of barley and wheat to conduct experiments on them. Brachypodium distachyon that belongs to grass family has recently emerged as a model organism for crops. It shares common characteristics for a model plant due to its small genome, small physical plant size, a short lifecycle, and less deman...
Investigation of the role of glutathione S-transferase isozymes in pyrethroid resistance of Helicoverpa armigera in Turkey Konus, Metin; Ugurlu, Sakine; İşcan, Mesude (2009-09-13) Helicoverpa armigera, cotton bollworm, is one of the insects causing severe yield loss of economically important crops including cotton, legumes and vegetables. It has developed resistance against the pyrethroid insecticides that have been introduced into market. Resistance against pyrethroids have been reported in H. armigera populations at various parts of the world, however, except 1-chloro-2,4-dinitrobenzene substrate (CDNB), almost no any other substrates used for analysis of the role of glutathione S-...
Controlled release of aldicarb from carboxymethyl cellulose microspheres: in vitro and field applications Kok, FN; Arica, MY; Gencer, O; Abak, Kazım; Hasırcı, Vasıf Nejat (1999-12-01) Aldicarb is a carbamate pesticide that is widely used throughout the world in the protection Of crops (eg cotton, nuts, potatoes, onion, tobacco, sugar beet and sugar cane). In Turkey, especially in the Cukurova region, it is used for the control of the cotton white fly (Bemisia tabaci) which attacks cotton plants cultivated in this region. Aldicarb contamination in surface and ground water is a serious problem in several countries, partly due to its high water solubility. It is also highly toxic to mammals...
