Effect of organic nutrient sources on biological properties of soil in potato and turmeric cropping system

The field experiment was conducted during 2016-17 and 2017-18 to study the effect of organic nutrient sources on soil biological properties of potato and turmeric. The field experiments were laid out in randomized block design with four replications and eight treatments. The eight treatments were T1 (100% RD N through VC & PM on 50:50 N-equivalence basis), T2 (90% RD N through VC & PM on 50:50 N equivalence basis), T3 (80% RD N through VC & PM on 50:50 Nequivalence basis), T4 (70% RD N through VC & PM on 50:50 N-equivalence basis), T5 (60% RD N through VC & PM on 50:50 N equivalence basis), T6 (50% RD N through VC & PM on 50:50 N-equivalence basis), T7 (40% RD N through VC & PM on 50:50 N-equivalence basis) and T8 (Control only FYM). Organic nutrient sources significantly influenced microbial properties of potato and turmeric. The microbial properties were higher in T1 (100% RD N through VC & PM on 50:50 N-equivalence basis) treatment and lowest in control. The application of 100% RD N showed positive impact on microbial properties of soil and also enhanced fertility status of soil, which ultimately reflects a healthy soil. | Effect of organic nutrient sources on biological properties of soil in potato and turmeric cropping system
