Abstract
Nickel is an essential micronutrient for leguminous plants. It has a large range between limiting and toxic levels. A pot experiment was conducted on two dominant soil series of Jharkhand i.e., Upland [Sidhamantoli (ST-5)] and Lowland [Tetratoli (TT-5)]. Five application levels of Ni, viz. 0.0, 2.5, 5.0, 10.0 and 20.0 mg kg−1 with pea (Pisum sativum L.) as test crop were arranged in three blocks in a glass house. An increasing trend of pea dry matter was observed with increasing Ni application level up to 10.0 mg kg−1. Nickel content in pea plant over control was found 1.36 to 2.53 folds higher with Ni application 2.5 to 20.0 mg kg−1. Accumulation of Ni in soil of Sidhamantoli series (upland situation) was noticed 1.11–4.29 mg kg−1 in top and 1.31–5.68 mg kg−1 in bottom of the pot, while in Tetratoli soil series (low land situation) Ni content was found 1.40–5.35 mg kg−1 in top and 1.25–4.95 mg kg−1 in bottom soil. Nickel application stimulates Plant growth parameters and that gradually increased with increasing Ni application levels up to 5.0 mg kg−1 in Sidhamantoli and up to 10.0 mg kg−1 in Tetratoli soil series, while at 20 mg kg−1 Ni application in both soil conditions showed negative effect. So, appropriate precaution should be maintained in application of Ni in leguminous plants and fixed a threshold value of Ni application level 5.0 mg kg−1 in upland Sidhamantoli (ST-5) and 10.0 mg kg−1 in low land Tetratoli (TT-5) soil series of Jharkhand plateau.
