A field experiment was undertaken Regional Agricultural Research Station, Nandyal during 2018-18 and 2019-20 to studythe effect of crop residue incorporation, sowing time and irrigation on chickpea (Cicer arietinum. L.) under double cropping system in vertisols of Andhra Pradesh. The data pooled over for two successive years revealed that significantly higher dry matter production (4642 kg ha-1), seed yield (1546 kg ha-1) was recorded with incorporation of foxtail millet crop residue. Chickpea sown during November 1st FN recorded significantly higher number of pods per plant (33.1), seed weight plant-1 (10.1 g), dry matter production (4719 kg ha-1), seed yield (1660 kg ha-1) and stover yield (3524 kg ha-1). Application of irrigation during pre-flowering and pod development stage recorded significantly higher plant height (45.3 cm), number of branches plant-1 (8.4),number of pods plant-1 (34.1), seed weight plant-1 (10.1 g), dry matter production (4861 kg ha-1), seed yield (1819 kg ha-1), stover yield (3926 kg ha-1)and harvest index (46.3). Interaction effect between foxtail millet crop residue incorporation and November 1st FN sowing recorded significantly higher dry matter production (5146 kg ha-1) and seed yield (1839 kg ha-1) of chickpea, which proved to be best option for rabi chickpea production.
