Abstract

A trial was conducted to identify optimum sowing time for sesame in North Coastal Zone of Andhra Pradesh under irrigated conditions at Regional Agricultural Research Station, Anakapalle during rabi 2020-21 and 2021-22. The treatments consisted of two varieties of Sesame as main plots and six sowing dates in split plot design replicated thrice. The results of the trial revealed that optimum sowing time for sowing of Sesame under irrigated conditions in North Coastal Zone is second fortnight of December. Among the varieties, brown seeded variety (YLM 66) gave significantly higher seed yield than white seeded Variety (Swetha til) and was found suitable to NC zone. For brown seeded Sesame, YLM 66 sown during first fortnight of December to first fortnight of January gave higher seed yields as compared to other dates of sowing. For white seeded sesame, sowing during second fortnight of December gave higher seed yield. Delay in sowing beyond first fortnight of January for brown seeded sesame and beyond second fortnight of December for white seeded sesame reduced the seed yield significantly.
