Abstract:

The initial soil was silty loam having pH 4.90, Organic matter 1.92%, total N 0.12%, available P 4.00 µg g-1, K 0.040 meq 100 g-1, available Ca 1.50 meq 100 g-1, Mg 0.98 meq 100 g-1 and S 12.00 µg g-1. There were six lime treatments viz.T1: Control, T2 : 0.5 t lime ha-1 , T3 : 1.0 t lime ha-1, T4 : 1.5 t lime ha-1, T5 : 2.0 t lime ha-1, and T6 : 2.5 t lime ha-1. Dolochun was used as the liming material. The design of the experiment was Randomized Complete Block Design (RCBD )with three replications. Every plot received 140.0 kg N, 25.0 kg P, 106.0 kg K, 3.06 kg S, 3.6 kg Zn and 0.6 kg B ha-1 from urea, TSP, MoP, gypsum, zinc sulphate (monohydrate) and boric acid, respectively. The post harvest soils were analyzed for pH, OM, available P, Ca, Mg and K. The application of different rates of lime to soil progressively increased pH, OM and availability of P and gradually decreased K, Ca and Mg in soils at 30 DAL. Liming significantly increased at 30 DAL pH, OM but K, P, Ca, Mg decreased from 60 DAL up to 120 DAL. Available K, P, Ca and Mg were significantly increased due to application of lime which was mainly associated with increased wheat yields.
