Effect of time of sowing and hybrids on growth and yield of tropical sugarbeet.

摘要

To evaluate the optimum time of sowing with suitable hybrids of tropical sugarbeet, an investigation was carried out in Coimbatore, Tamil Nadu, India, during 2004-05. The main plot consisted of four times of sowing (15 days interval from 1 October to 15 November) and three tropical sugarbeet hybrids (Cauvery, Indus and Shubhra) in the subplot. The highest growth, yield attributes and yield were recorded in October first fortnight sowing with Cauvery and it was comparable with October second fortnight sowing with the same hybrid. All the three hybrids had yield potential ranging from 70 to 100 t/ha. Among the hybrids, the highest root yield was recorded in Cauvery (92 t/ha), followed by Indus (76 t/ha), and Shubhra registered the lowest yield of 71 t/ha. For quality parameter, Shubhra recorded the highest brix reading of 21%, followed by Indus (17%) and Cauvery (16%). October sowing with Cauvery performed best for tropical sugarbeet emergence, establishment, yield and quality.
