Field experiments were conducted at two locations, viz., Kannur (Kerala) and Chettalli (Kodagu,
Karnataka) for evaluating the efficacy of sulphate of potash (SOP) as a source of potassium (K)
on black pepper. There were nine treatment combinations viz., T1 -Control, T2 -Recommended
(Rec.) K as muriate of potash (MOP), T3 -Rec. K as SOP, T4 -125% of Rec. K as SOP, T5 -T3 + SOP 2%
foliar spray, T6 -50% of Rec. K as SOP + SOP 2% foliar spray, T7 -50% of Rec. K as SOP, T8 -T2 + Mg
@ 25 kg ha-1 as MgSO4 and T9 - T3 + Mg @ 25 kg ha-1 as MgSO4 laid out in a randomized block
design with three replications. The results showed that soil nutrient status in treatment with
25.0% higher recommended K as SOP recorded significantly higher concentrations of soil organic
carbon, K, Ca, S, Zn and Cu. The study further revealed that for economic yield of high quality
black pepper, 50% of recommended dose of K as SOP for soils of high K status and 100%
recommended K as SOP + 2% foliar spray of SOP for soil of low K status can be recommended
