Abstract: Ni is considered as an essential element primarily because of its function as an irreplaceable component of urease which is responsible for the hydrolysis of urea N. Urea N acquired by plant is not available for plant N metabolism unless hydrolyzed to CO2 and NH3. Ni deficiency in legumes and other dicots causes a decrease in the activity of enzyme urease, a condition that causes accumulation of toxic levels of urea and is manifested as necrosis at the tip of the leaves. A field experiment was conducted during Zaid season of 2021on research plot of Udai Pratap (Autonomous) College, Varanasi (U.P.) adjoining the Department of Agricultural Chemistry and Soil Science. The physicochemical properties of the experimental soil were; pH (7.43), EC (0.48 dS m
-1); organic carbon (0.55%), available nitrogen (243.18 kg ha
-1), available phosphorus (18.32 kg ha
-1), available potassium (212.30 kg ha-1), available nickel (Trace). The experiment was carried out in randomized block design (RBD) with six treatments and three replications. Treatment were T0 = Control (RDF N: P: K), T
1 = RDF+ Ni @ 0.50 kg ha
-1, T
2 = RDF + Ni @ 1.00 kg ha
-1, T
3 = RDF + Ni @ 1.50 kg ha
-1, T
4 = RDF+ Ni @ 2.00 kg ha-1, T
5 = RDF + Ni @ 2.50 kg ha
-1. The growth parameters (plant height, number of leaves and number of branches) were significantly increased by different treatments. The minimum value was recorded with control (without nickel) and maximum with treatment T4 (Ni @ 2 kg ha
-1) at 15, 30, 45 and 60 days after sowing. Application of nickel at different levels increased the dry matter production. Highest seed and stover yields were recorded with treatment comprising Ni @ 2 kg ha-1. All the treatments have significant effect in case of N, P and K content in stover. The minimum concentration of N, P and K was recorded in case of control and maximum in T4. Similar trend was also found in case of N, P and K uptake by stover. Available N, P and K status of postharvest soil were also significantly affected by different treatments. The minimum amounts were recorded with treatment T0 (without nickel) and maximum with treatment T
4 (Ni @ 2 kg ha
-1). The application of nickel significantly affected the growth, yield and nutrient uptake by green gram. The available N, P and K status of post-harvest soil was also increased. The application of 2.0 kg ha¬¬¬-1 with20 kg N ha
-1, 50 kg P
2O
5 ha-1 and 40 kg K
2O ha
-1 was found to be the best treatment regarding growth, yield, nutrients uptake and N, P and K status of soil.
