PERFORMANCES OF DOLOCHUN AS A SOURCE OF MAGNESIUM FOR SUGARCANE AT FARMERS FIELD UNDER OLD HIMALAYAN PIEDMONT PLAIN

Abstract

A Verification trial was conducted in 2005-2006 cropping season at farmers field of Thakurgaon and Panchagar districts to evaluate the performances of dolochun as a source of magnesium on sugarcane production. Four levels of magnesium (0. 20. 40 & 60kg ha-1 ) from dolochun with recommended dose of NPKS were applied equally to all the treatments. Application of dolochun @ 40 kg Mg ha-1 significantly increased the number of millable canes, cane yield and brix percentage. The minimum number of tiller, number of millable cane and cane yield were produced in control plot with recommended NPKS fertilizers where no magnesium was applied. Results revealed that the application of dolochun at 40 kg Mg ha1 with recommended fertilizers (N12, P35, K100, S25 & Zn2 kg ha-1 ) produced significantly higher sugarcane yield (91.37 that millable cane (88.15 x l03 ha-1 ) and brix % (22.87) among all other treatments under study.
