Effect of Management Practices on Growth and Productivity of Chip Bud Raised Sugarcane (Saccharum offcinarum L.)

Field investigations were carried out during early seasons of 2014 to 2016 at Sugarcane Research Station, Cuddalore to ascertain the effect of intra-row spacings doses of NPK, addition of bio- inoculants in combination with the practice of topping under conventional method of flooding irrigation forchipbud raised sugarcane seedlings. The adoption of 30 cm intra-row spacings + 100% dose of NPK+ topping treatment registered significantly maximum number of tillers per hectare, however, the maintenance of 45 cm intra- row spacings + 100 % recommended dose of NPK + topping registered the maximum values of varied growth, yield parameters viz., cane length (289 and 282 cm), cane girth (2.79 and 2.66 cm) individual cane weight (2.06 and 1.97kg) and millable canes (1,27,600 and 1,23,600) cane (140.43 and 129.94tha-1)and sugar yield (16.86 and 15.67tha-1).
