A field experiments were conducted on the “Impact of potato + pigeon pea based intercropping systems on microbial properties” in the premises of Agricultural Research Station (ARS), Madenur, Hassan Taluk and District during Kharif and Rabi 2017 and 2018. Experiment consisting of twelve treatments (T1: 100 % K through K2SO4 + NP through fertilizers for targeted yield of 20 t ha-1, T2: 100 % K through Bio-K + balance NP through fertilizers for targeted yield of 20 t ha-1, T3: 50 % K through Bio-K + 50 % K through K2SO4 + balance NP through fertilizers for targeted yield of 20 t ha-1, T4: 100 % K through K2SO4 + NP through fertilizers for targeted yield of 25 t ha-1, T5: 100 % K through Bio-K + balance NP through fertilizers for targeted yield of 25 t ha-1, T6: 50 % K through Bio-K + 50 % K through K2SO4 + balance NP through fertilizers for targeted yield of 25 t ha-1, T7: Recommended dose of fertilizers alone (75:75:100 kg NPK ha-1), T8: Package of Practice recommendation, UAS B) and replicated thrice. Among the soil biological properties, microbial activity viz., bacteria, fungi and actinomycetes count after harvest of potato was significantly higher in treatments receiving 100 % K through Bio-K + balance NP through fertilizers for targeted yield of 25 t ha-1 (15.87 x 106 Cfu g-1, 9.53 x 104 Cfu g-1 and 5.15 x 102 Cfu g-1, respectively) and it was on par with 50 % K through Bio-K + 50 % K through K2SO4 + balance NP through fertilizers for targeted yield of 25 t ha-1 (15.15 x 106 Cfu g-1, 9.23 x 104 Cfu g-1 and 5.02 x 102 Cfu g-1, respectively) across all the treatments in potato and finger millet (13.80 x 105 Cfu g-1, 8.36 x 103 Cfu g-1 and 3.06 x 102 Cfu g-1, respectively) across all the treatments.
