Evaluation of suitable tropical sugarbeet hybrids with optimum time of sowing.

The investigation was carried out in tropical sugarbeet at Tamil Nadu Agricultural University, Coimbatore to evaluate optimum time of sowing with suitable hybrids. The experiment was conducted in strip plot design. The main plot consists of four times of sowing (15 days interval from 1^st September to 15^th October) and three tropical sugarbeet hybrids (Cauvery, Indus and Shubhra) in sub plot. Higher crop biometrics of tropical sugarbeet was recorded in October 1^st sowing and was on par with 15^th September and 15^th October sowing. The yield characters and yield (72 and 88 tha⁻¹ during 2005 and 2006 respectively) of tropical sugarbeet and brix reading were higher in 1^st October sowing during both the experiments conducted during 2005–06 and 2006–07. With respect to tropical sugarbeet hybrids, Cauvery performed better in yield (76 and 92 t ha⁻¹ during 2005 and 2006 respectively) and Shubhra recorded higher brix reading (20%). September second fortnight to October second fortnight sowing with Cauvery hybrid performed better for tropical sugarbeet emergence, establishment, yield and quality. [ABSTRACT FROM AUTHOR]
