| dc.description.abstract | To investigate the status of Nickel, its sorption –desorption and response behaviour of wheat to its application, laboratory and screen house experiment were conducted. For the purpose of this study the soil samples were collected from different sites within the Haryana covering the selected soil series and major soil orders of Haryana. The soil samples were found neutral to slightly alkaline in reaction, non-saline and having low organic carbon and nil to medium CaCO3 content. Sorption and desorption of Nickel from these soils were also estimated. The texture of the soil varied widely from sand to sandy clay loam. The highest DTPA- extractable and total nickel content was found in Gurgaon and Rohtak, respectively. Available and total Nickel content was significantly negatively correlated with pH (r = -0.174*) for available Nickel and pH (r = -0.259**) for total Nickel. Available Ni was also found significantly negatively correlated with CaCO3 (r = -0.194*). Among the eighteen samples collected from well established soil series of Haryana, the maximum sorption (37.76 μg g-1) and desorption (19.28 μg g-1) of Nickel was reported from soil samples of Nimriwali and Lukhi soil series, respectively. Whereas, minimum sorption (32.56 μg g-1) and desorption (2.47 μg g-1) of Nickel was obtained from the soil samples of Berpura and Isarwal series. Sorption and desorption behaviour of different levels of Ni (0, 5, 10, 20, 30, 60 and 90 μg g-1) in four soil samples selected from four major orders of Haryana were studied. The adsorption isotherm obtained from Nickel concentration in equilibrium (C; μg ml-1) vs. Ni adsorbed (X; μg g-1) indicated that the amount of adsorbed Ni increased with an increase in equilibrium Ni concentration in all the four experimental soils. Linear, Freundlich and Langmuir adsorption equations were also considered to explain the sorption equilibrium of Nickel in these soils. The higher value of prediction coefficients (R2) for all the soils indicating that Freundlich equation could explain Ni sorption in experimental soils to a reasonably good extent. In soil of Aridisols, wheat seed, straw and biological yield decreased with increased application of Nickel from 0 to 100 mg kg-1. Whereas in soils of Entisols, Alfisols and Inceptisols an increment in yield of seed and straw was reported upto the level20 mg Ni kg-1.The concentration of Nickel in seed, straw as well as in soil after harvesting of wheat crop significantly increases with the increase in doses of applied Nickel in all the four soil samples. The maximum nickel content in wheat grain and straw in Aridisols, Entisols, Alfisoils and Inceptisols, respectively was found at 100 mg Ni kg-1.The protein and chlorophyll content was decreased with the increased application of Nickel. The minimum crude protein content 8.66 for Aridisols, 8.85 for Entisols, 9.11 for Alfisols and Inceptisols, as nickel was applied at higher rate i.e. 100 mg Ni kg-1.The highest nickel use efficiency, utilization efficiency and uptake efficiency in wheat was found with the low level of Nickel application. | en_US |
