A field investigation was carried out at Regional Agricultural Research Station, Warangal on Vertisols during Kharif 2016-17, 2017-18, 2018-19 to study the effect of nipping and plant geometries in medium duration pigeonpea productivity under rainfed conditions of Telangana. Nipping terminal bud at 45 and 60 days after sowing significantly reduced the plant height and increased the number of primary and secondary branches and pods per plant. Pooled results inferred that one time nipping at 45 days (1688 kg ha-1) has significantly out yielded the other treatments. With single time nipping at 60 days after sowing, nipping twice at 45 and 60 days after sowing and control there is an increase in grain yield by 12 %, 18 % and 16 % respectively over single time nipping at 45 days after sowing. While, grain yield was not influenced by the plant geometries. Interaction was also found significant with single time nipping at 45 days after sowing with 41,666 plants ha-1plant geometry(1763 kg ha-1) and it was at par with single time nipping at 45 days after sowing at 27,777 plants ha-1plant geometry (1748 kg ha-1) over the other treatments..
