PERFORMANCE OF SUGARCANE SOMACLONES UNDER DIFFERENT IRRIGATION AND FERTILIZERS DOSES

Abstract

In vitro grown plantlets (somaclones) were regenerated through callus culture. Selected somaclone along with parent were tested under different fertilizer and irrigation levels for agronomic and qualitative traits of parent/clones. Maximum plant height, and internodes (plant-1) was observed in NIA-98 somaclone. The tillers (plant-1), weight plant-1, cane yield, sucrose and purity were greater in AEC82-1026 somaclone and maximum stem girth was obtained in BL4 somaclone from the combination of 150-80-100 NPK (kg ha-1) with 25 irrigations during the growing season. It was concluded that the application of 150-80-100 kg NPK ha-1 and 25 irrigations during the growth period of sugarcane were efficient for achieving better agronomic and qualitative traits of sugarcane somaclones.
