INFLUENCE OF VARIOUS LEVELS OF NITROGEN AND POTASSIUM ON YIELD ATTRIBUTING CHARACTERS IN TURMERIC GENOTYPESKamlesh Ahirwar S.B. Singh, Ajay Khare and Rajesh Jatav
The study was conducted in split plot design with three genotypes viz; Roma, PCT-8 and Suroma as main plot treatment and nine fertility levels as sub plot treatment replicated three times. Roma recorded maximum length of mother rhizome (6.93 cm), weight of primary rhizome (23.62 q/plant), weight of secondary rhizomes (29.50 g/plant) and fresh weight of rhizomes (69.92 g/plant). Suroma recorded the minimum length of mother rhizome (6.51 cm), weight of primary rhizome (21.54 g/plant), weight of secondary rhizomes (27.45 g/plant) and fresh weight of rhizomes (68.11 g/plant). The fresh yield of rhizomes (101.72 q/ha) and dry matter recovery (37.39%) were found to be significantly higher in case of Roma genotype of turmeric over PCT-8 and Suroma. The increasing N and K fertilizer nutrients from N100K100 to N200K200 increased the yield-attributing characters slightly, i.e. non-significantly. The fresh weight of rhizomes per plant was also not influenced significantly due to increased N and K levels upto N200K200. The maximum productivity viz. fresh yield of rhizomes (100.90 q/ha) was recorded in case of N200K200.
