Out of seven essential micronutrients, Ni is on the recently added essential plant nutrient. Ni is an important metal for plants which fulfils a variety of vital roles in plant functions. It is a micronutrient involved in nitrogen metabolism and a constituent of the urease molecule. Ni a component of urease and hydrogenase plays variety of vital roles in plant functions. Thoroughly, planned a field experiment was conducted in rabi season of 2017-18 at the Research Plot of Department of Agricultural Chemistry and Soil Science, Udai Pratap (Autonomous) College, Varanasi. The experiment was carried out in Factorial Randomized Block Design (FRBD) with three replications. Treatments includes four nickel levels with two nitrogen levels and three nitrogen sources viz; N0 (no nitrogen), N120UR (Urea), N120AS (ammonium sulphate), N120CAN (calcium ammonium nitrate) and four nickel levels 0,1,2 and 4 kg ha-1 (Ni0, Ni1, Ni2 and Ni4). Nitrogen was applied @ 120 kg ha-1with different nitrogen sources used. Ni was applied in the form of NiCl2. H2O as per the requirement of treatment as basal dose. Important growth parameters (plant height and number of tillers) at different growth stages and dry matter yield (grain and straw) were determined. Results revealed that nitrogen and nickel supply significantly affected all the parameters under study when compared with no supply of nitrogen and nickel. The nitrogen application through urea registered the highest growth parameters and dry matter yield as compared to ammonium sulphate and calcium ammonium nitrate. The nickel application @ 2 kg ha-1 recorded significantly maximum increase in all growth attributes as well as yield attributes. The interaction effect was found significant. Due to interaction effect maximum plant height, number of tillers, test weight, grain and straw yield were recorded when 2 kg ha-1 Ni was applied in combination of urea (N120UR) followed by ammonium sulphate (N120AS) and calcium ammonium nitrate (N120CAN) with the treatment N120UR Ni2, followed by N120AS Ni2 and N120CAN Ni2.
