Description A two-year field experiment was conducted to investigate the effect of sub-soiling on plant growth, root morphology and yield of rainfed pigeonpea [Cajanus cajan (L. ) Millsp.] (Var LRG 41) during 2012-13 and 2013-14. Crop exposed to moisture stress condition from flowering to harvest (120 days) during 2013-14, compared to experiment conducted during 2012-13. The results indicated that sub-soil tillage sustained higher shoot, root growth and seed yield during the year 2013-14, which coincided with end of season drought compared to conventional tillage treatment. Crop growth in terms of plant height, leaf area/plant significantly improved due to sub-soiling compared to conventionally tilled treatment. Similarly sub-soiling recorded significant increase in drought tolerant traits, viz. root length (234%), root dry weight (274%) and relative water content (37%). Consequently, sub-soil tillage recorded significant increase in number of pods/plant by 59%, 100 seed weight by 12% and pod yield by 219% compared to conventionally tilled treatment. Sub-soil tillage proved efficient method of mechanical intervention for drought mitigation under rainfed pigeonpea cultivation.
