A field experiment was conducted to study the performance of pigeonpea genotypes at different dates of sowing and spacing under rainfed conditions in clay loam soils. The experiment consisted of three genotypes [‘ICP 8863’ (Maruthi), ‘TTB 7’, and ‘WRP 1’], two sowing dates (normal and delayed) and two spacings (100 x 20 cm and 50 x 20 cm). Normal sown pigeonpea produced significantly higher yield attributes and yield compared to delayed sowing. A reduction of 23% in the mean seed yield was observed with delay in sowing by 15–30 days. Under delayed sowing, ‘ICP 8863’ (Maruthi) performed better than ‘TTB 7’ and ‘WRP 1’. However, spacing did not influence the growth and yield of pigeonpea under delayed sowing. The pod damage by Helicoverpa armigera was higher in ‘WRP 1’ and in normal sown crop, while wilt caused by Fusarium udum was higher in ‘TTB 7’. Higher net returns were obtained with early sowing and ‘ICP 8863’ (` 9720 ha−1) compared to other genotypes.
