The influence of sowing dates on tikka late leaf spot (TLLS) and pod and haulms yields in groundnut were studied during 1991–92, 1992–93 and 1993–94 rabi and summer seasons. Maximum TLLS severity (7.83 to 8.42) was recorded on the crop sown in early rabi (5 and 20 October). The disease severity has graduaUy decreased from 7.33 (in the crop sown on 5 November in normal rabi to 1.33 (in the crop sown on 20 April in summer). The highest pod and haulms yields (29 and 32 q/ha) respectively were obtained from the crop sown on 5 December, The crop sown on 20 November was the next best with pod and haulms yields of 28.0 and 30.66 q/ha respectively. The best sowing time for the groundnut in the Southern Zone of Andhra Pradesh was found to be 20 November to 5 December in normal rabi, since very less disease severity was recorded.
