^*Data represents percent DRR incidence in chickpea field location 1 and 2. Average of 2–3 block replicates are represented here. RCBD two-way ANOVA was used for the comparison of the mean for each experiment and significance was assessed by the least significant difference (LSD at p < 0.05) post hoc test. Statistics are performed column-wise. Different letters (a, b, c, d, e) in a column denote significant difference between mean at p < 0.05. DS = drought stress; CS = combined stress; CV = coefficient of variance; LSD = least significant difference; NA = treatments could not be maintained in field experiment thus data is not available. Field location-1 = NIPGR, New Delhi; Field location-2 = GKVK, Bengaluru. Data shows an increase in the DRR incidence under severe CS treatment compared to pathogen treatment.
