A field experiment was conducted at S.V. Agricultural College Wetland farm, Tirupati to study the performance of sweet corn cultivars under varied times of sowing in Southern Agro-Climatic Zone of Andhra Pradesh during rabi 2011. The treatments consisted of combination of two factors viz., three varieties (Madhuri, Sugar 75, Misthi) and four times of sowing (October first fortnight, October second fort night, November first fortnight and November second fortnight). Among the cultivars Misthi produced significant higher green cob yield of 17910 kg ha1 with maximum values of growth and yield attributes over other cultivars. Sweet corn sown in first fortnight of October gives cob yield of 28291 kg ha-1 with maximum growth attributing characters than the subsequent delayed sowing.
