Influence of spacing on growth and yield of sugarcane raised throughin vitro micropropagation

Abstract

The role of quality seed in improving the productivity of sugarcane both in terms of quality and yield, is well recognized. At Parry’s Sugarcane Research and Development Centre, sugarcane micropropagation methods have been standardized and the three-tier seed production system is being followed for the introduction of new varieties and also ruling varieties. Field experiments were conducted at Parry’s research farm by planting sugarcane variety Co 86032 raised through micropropagation with different spacing viz., 90 × 60 cm, 90 × 90 cm, 120 × 60 cm and 120 × 90 cm during 2002-03 planting season. Among the four spacings, 90 × 60 cm recorded the highest tiller number of 1.88 lakh/ha, 203.93 cm stalk length, internode length of 12.59 cm and cane yield of 105.90 t/ha. Thus, a spacing of 90 × 60 cm was found suitable for raising tissue culture raised Co 86032 variety.
