Effect of Different Level of NPK and CRF for Plant Growth and Rhizome Yield in Arrowroot (Maranta arundinacea L.)

The present investigation was carried out to Effect of different level of NPK and CRF for plant growth and rhizome yield in Arrowroot (Maranta arundinacea L.) was conducted in the horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higgin bottom University of Agriculture Technology and Sciences, Prayagraj (U.P.) during July 2021- April 2022. The experiment was laid out in RBD with 11 Treatments with 3 replications. The results revealed that the treatment T10 100% CRF(Control Release Fertilizer)performed the best in terms in Plant height (140.22), leaf length (49.06), leaf width (19.10), No. of tillers(14.33), fresh weight per plant (736.33), Number of rhizomes per plant (11.33), yield of rhizomes per plant (11.78), yield of rhizomes per hectare (81.81), Maximum cost benefit (3.50). Therefore, the treatment T10 100% CRF is the best when compared to other treatments. As, the highest benefit cost ratio was observed in T10 100% CRF. i.e. (3.50).
