Nitrogen management in sugarcane seed crop

A field experiment was conducted for three consecutive years from 1997 –98 to 1999–2000 at Regional Agricultural Research Station, Anakapalle to study the effect of nitrogen levels and its time of application on yield and quality of sugarcane seed crop and its impact on performance of succeeding commercial crop. The study indicated that application of nitrogen at 100% recommended dose in two equal splits at 45 and 90 DAP was more advantageous for realizing higher seed cane yield. Extending nitrogen application up to 135 days had favourable influence on seed quality with lower sucrose and higher glucose content in seed cane. The yield and quality of commercial crop raised with recommended nutrients application was not influenced by the seed crop which received different nitrogen levels applied at specified growth stages of the seed crop.
